[0075] 本发明的翻转扬声器100,能够应用于电子产品上,所述电子产品应包括通过第一转轴I枢转连接的第一部件和第二部件,为了容易理解,本发明的电子产品以笔记本电脑为例进行说明,第一部件为笔记本电脑的显示端200,而第二部件则为笔记本电脑的系统端300。 [0075] Flip speaker 100 of the invention, the electronic products can be used in the electronic products should include a first member and a second member through a first pivot shaft I connected, for easy understanding of the present invention to electronic products notebook computers as an example, the first component of a laptop display terminal 200, and the second part was a laptop system side 300.

[0076] 下面结合附图对本发明的翻转扬声器100的具体结构和工作原理进行详细说明。 [0076] the following with reference to flip the speaker of the present invention specific structure and working principle 100 will be described in detail.

[0077] 如图1和图2所不,本发明的翻转扬声器包括:扬声器本体2和传动机构至少包括第一转轴I和第二转轴3 ;显示端200和系统端300通过第一转轴I枢转连接;扬声器本体2通过第二转轴3枢转连接在系统端300上,第一转轴I和第二转轴3相平行设置。 [0077] FIGS. 1 and 2 do not, flip the speaker of the present invention includes: a speaker body 2 and the transmission mechanism comprises at least a first and a second rotary shaft I 3; display end 200 and 300 systems by the end of the first pivot axis I turn connected; speaker body 2 through the second rotary shaft 3 is pivotally connected to the system side 300, a first rotary shaft and second rotary shaft 3 I parallel set. 当显示端200由O度(本发明中提及的显示端200的角度均为显示端200相对系统端300的夹角)开始转动(正向转动)时,能够通过传动机构带动扬声器本体2转动,当扬声器本体2转动至预定角度后,显示端200继续转动,而扬声器本体2保持在该角度不动。 When the display side 200 by the O degrees (angle display terminal of the present invention are mentioned in 200 display system side angle opposite end 200 300) starts to rotate (forward rotation), it is possible to drive through a transmission mechanism to rotate the speaker body 2 When speaker body 2 is rotated to a predetermined angle, the display terminal 200 continues to rotate, and the speaker body 2 held at this angle does not move. 同时扬声器本体2在转动的过程中可实现开启状态与关闭状态的切换,即在O度时,扬声器本体2处于关闭状态(禁声状态),当扬声器本体2转动至预定角度时,触发扬声器本体2的开关10,使扬声器本体2由禁声状态转换至开启状态(允许发声状态)。 At the same time the speaker body 2 may be implemented in the course of the rotation toggle the state and the closed state, that is, when O degrees, speaker body 2 in the closed state (gag state), when the speaker body 2 is rotated to a predetermined angle, trigger speaker body 2 switch 10, the speaker sound body 2 transition from state to ban on state (allowing vocal state).

[0078] 如图3所示,所述传动机构还包括:第一齿轮4、第二齿轮5和齿条6,第一齿轮4固定在第一转轴I上,显示端200与第一转轴I固定连接,显示端200转动时带动第一转轴I和第二齿轮4转动;第二齿轮5固定在第二转轴3上,扬声器本体2与第二转轴3固定连接;齿条6具有分别与第一齿轮4和第二齿轮5相嗤合的第一齿部7和第二齿部8,第一齿轮4随显示端200转动时推动齿条6朝向第二齿轮5的方向移动,由于齿条6的第二齿部8与第二齿轮5相啮合,因此齿条6的移动能够带动第二齿轮5及扬声器本体2转动。 [0078] shown in Figure 3, the drive mechanism further comprises: a first gear 4, 5 and the second gear rack 6, a first gear 4 is fixed to the first rotary shaft I, the first rotary shaft 200 and the display terminal I fixedly connected, a first display drive shaft I and the second gear 4 is rotated to rotate end 200; second gear 5 is fixed to the second rotary shaft 3, the speaker main body 2 is fixedly connected with the second rotary shaft 3; 6 having respectively first rack a gear 4 and 7 of the first tooth and a second tooth of the second gear 5 relative laugh together 8, the first show to promote the rack gear 4 with 6 direction towards the second gear 5 moves end 200 is rotated, since the rack 6 second tooth portion 8 is engaged with the second gear 5, 6 can therefore move the rack drive gear 5 and the second speaker body 2 is rotated. 由于扬声器本体2无需像显示端200 —样,工作状态至少旋转至90度(一般会大于90度)。 Since the speaker body 2 without image display side 200-- like, work status rotated at least 90 degrees (typically greater than 90 degrees). 而扬声器本体2只需转动一定角度使其上的出音孔9露出即可(一般无需大于90度)。 The speaker body 2 by simply turning on an angle so that it is exposed to the sound hole 9 (generally without more than 90 degrees). 因此,当显示端200转动时,只需通过齿条6带动扬声器本体2转动至预定角度(例如60度)即可,当显示端200继续转动时不会再带动扬声器本体2转动。 Therefore, when the display side 200 is rotated, only 6 driven by a rack speaker body 2 is rotated to a predetermined angle (eg 60 degrees) can be, when the display terminal 200 continues to rotate the speaker will not be driven by rotation of the body 2. 齿条6上还具有用于控制开关10启闭的按压部11。 Rack also has a pressing portion for controlling the opening and closing of the switch 10 11 6. 开关10的设置位置固定不动,按压部11随齿条6的移动而移动,按压部11在移动时与开关10触碰或分离(触碰时扬声器本体2禁声,分离时扬声器本体2发声),从而实现开关10的启闭。 Set the position switch 10 fixed and mobile pressing portion 11 with the rack 6 is moved, when the pressing portion 11 moves with the switch 10 touch or separation (touch the speaker body 2 gag, separation speaker sound body 2 ), in order to achieve the opening and closing of the switch 10.

[0079] 为了实现显示端200仅带动扬声器本体2转动至预定角度后不再继续跟随显示端200的翻转而翻转,就应该在显示端200继续翻转时,第一齿轮4不再驱动齿轮6移动或者第二齿轮5不再与齿条6相啮合。 [0079] In order to achieve the display terminal 200 to drive the speaker only after the body 2 to a predetermined angle of rotation no longer continue to follow the display side flip 200 and flip, it should continue to flip the display side 200, a first gear 4 is no longer driven gear 6 is moved 5 or the second gear 6 is no longer meshed with the rack. 本实施例中采用的是当扬声器本体2转动至预定角度后,第一齿轮4脱离与齿条的啮合,第一齿轮4继续转动时齿条6保持不动。 This embodiment is used when the speaker after the body 2 is rotated to a predetermined angle, 4 out of first gear meshing with the rack, 4 to continue to rotate the first gear rack 6 remain intact. 如图3所示,并同时结合图4、图5和图6,具体的结构为:第一齿部7和第二齿部8分别位于齿条6的靠近两端部;第一齿轮4和第一齿部7的相啮合段短于第二齿轮5和第二齿部8的相啮合段。 As shown in Figure 3, and also in conjunction with Figure 4, Figure 5 and Figure 6, a specific configuration of: a first toothed portion 7 and the second rack tooth portion 8 are located close to both end portions 6; a first gear 4 and a first tooth segment engaged portion 7 is shorter than the second gear 5 and the second teeth portion meshed section 8. 本实施例中的第一齿轮4的轮面上没有完全布满齿,而是仅设置了部分齿,当第一齿轮4转动一定角度后,即使继续转动也不会带动齿条6继续移动。 Examples of the surface of the first gear wheel 4 of the present embodiment is not completely covered with teeth, but is only a partial set of teeth, when the first gear 4 is rotated a certain angle, it will not continue to rotate even if the drive continues to move the rack 6. 同样的,第二齿轮5也仅设置部分齿,大部分轮面是光滑的,但第二齿轮5上的齿比第一齿轮4上的齿多,且第二齿部8比第一齿部7长。 Similarly, the second gear 5 is also provided only partial tooth, the majority of the tread is smooth, but the second gear 5 on the gear ratio of the teeth on the first gear more than 4, and a second gear portion 8 than the first tooth portion 7 Long.

[0080] 实际上,第一齿部7的齿数与第一齿轮4上的齿数可以相等也可以不相等,同样的,第二齿部8的齿数与第二齿轮5上的齿数可以相等也可以不相等,只要保证当显示端200转动至大于扬声器本体2的所述预定角度时,显示端200的转动不会再带动扬声器本体2继续跟随转动即可。 [0080] In fact, the number of teeth on the gear 4 with the first gear portion 7 of the first teeth can be equal or may not be equal to the same number of teeth of the second tooth portion 8 and the number of teeth on the second gear 5 can also be equal to not equal, as long as the rotation when the display terminal 200 to greater than the predetermined angle speaker body 2, the display side 200 of the rotation will not be driven by speaker body 2 continues to follow the rotation can be. 如图3所示,本实施例中第一齿部7的齿数与第一齿轮4上的齿数相等,而第二齿部8的齿数多于第二齿轮8上的齿数;且第一齿部7的齿数少于第二齿部8的齿数。 3, the present embodiment 4 teeth on the first gear teeth of the first toothed portion 7 is equal, the number of teeth and the second teeth portion 8 is greater than the number of teeth on the second gear 8; and a first tooth portion 7 teeth less than the number of teeth of the second teeth portion 8.

[0081] 当显示端200处于工作角度时,即显示端200翻转至与系统端300呈大于90度的角度时,如果使用者只想关闭扬声器,可以只需向下按压使扬声器本体2翻转而处于禁声状态即可。 [0081] When the display is working angle end 200, which displays 200 flip side to the system side 300 is greater than the angle was 90 degrees, if the user want to turn off the loudspeaker, you can simply pressing down the speaker body 2 is inverted and in the state to gag. 因此,本发明的翻转扬声器还包括:止挡件12、推抵部13和弹性复位元件14,弹性复位元件14设置于在第二转轴3上,当扬声器本体2由所述预定角度反向转动时通过第二齿轮5将推动齿条6朝向第一齿轮I的方向移动,同时弹性复位元件14积蓄扭力。 Accordingly, the present invention further flip loudspeaker comprising: the stopper 12, abutting portion 13 and the elastic pushing the reset member 14, the elastic member 14 is provided to reset the second rotary shaft 3, when the speaker main body 2 by the reverse rotation of the predetermined angle 5 through the second gear rack 6 will drive in the direction towards the first gear I move, while 14 savings torsion elastic return element. 此过程中,止挡件12用于当齿条6运动至其上的按压部11与开关10触碰时,阻挡齿条6的继续运动,使齿条6保持在固定位置,同时也保证了第二齿轮5以及扬声器本体2的位置保持不动。 This process, the stopper 12 is used when the rack 6 moves to its pressing portion 11 and the switch 10 is touched, the barrier continues to move the rack 6, the rack 6 is held in a fixed position, but also to ensure 5 and the second gear position of the speaker of the body 2 remain intact. 由于按压部11与开关10触碰,使扬声器本体2处于禁声状态,实现了在显示端200处于工作角度时,能独立控制扬声器本体2的关闭。 Since the pressing portion 11 and the switch 10 touch, the speaker body 2 in the state gag realized at the display side 200 is working angle, can control speaker independent body closed 2. 推抵部13设置于第一齿轮4上,当显示端200由工作角度关闭至第一齿轮4与齿条6处于啮合状态或即将啮合状态时,推抵部13推抵止挡件12,使止挡件12解除对齿条6的止挡,在弹性复位元件14的扭力作用下,第二齿轮5正向转动,而齿条6则在第二齿轮5的带动下朝向第二齿轮5的方向移动,此时,本发明的整个翻转扬声器回复至初始状态(所谓初始状态,是指显示端200和扬声器本体2均处于O度的状态,按压部11与开关触碰,第一齿轮4与第一齿部7嗤合,第二齿轮5与第二齿部8啮合)。 Pushing abutment portion 13 is provided on the first gear 4, when the display 200 is closed by the working angle end to the first gear 4 in engagement with the rack 6 or about the engagement state, pushing abutment portion 13 is pushed against the stopper member 12, so that the stopper member 12 to lift the stopper on the rack 6, in the torque effect of elastic return element 14, the second forward gear 5 is rotated, the rack 6 and the second driven gear 5 toward the second gear 5 direction, this time, the speaker of the present invention, the entire flip reply to the initial state (the so-called initial state, the display side is the speaker body 200 and are in a state of O 2 degrees, the pressing portion 11 and the touch switch, and a first gear 4 laugh first tooth portion 7 together, the second gear 5 meshing with the second teeth portion 8).

[0082] 如图7和图8所示,并继续结合图2,止挡件12包括止挡片15和连接部16,止挡件12通过连接部16可以套设于第一转轴I上,但应当不随第一转轴I的转动而转动,也就是止挡件12的位置是固定不动的。 [0082] FIG. 7 and 8, and continue in conjunction with Figure 2, the stopper 12 includes a connecting portion 12 through 16 may be provided on a first axis I set the stopper plate 15 and the connecting portion 16, the stopper, it should not with rotation of the first shaft I rotates, that is, the position of the stopper member 12 is stationary. 止挡片15固定连接在连接部16上;齿条6的侧面上开设有止挡槽17,止挡片15具有与止挡槽17相配合的止挡部18。 The stopper plate 15 is fixedly connected to the connector section 16; on the side of the rack 6 opened a stopper groove 17, the stopper plate 15 has a stopper groove 17 cooperating with the stopper 18. 当齿条6在第二齿轮5的驱动下朝向第一齿轮4运动至按压部11与开关10触碰时,止挡部18卡入止挡槽17内,从而限制了齿条6的继续移动。 When the first gear rack 6 toward the second driving gear 5 is moved to the pressing portion 4 and the switch 10 is touched 11, the stopper portion 18 snaps into the stopper groove 17, thereby limiting the rack continues to move 6 . 如图8所示,止挡部18的端面为斜面,同样的,止挡槽17与其对应的槽壁也为斜面。 8, the end face of the stopper portion 18 is beveled, the same, but also for the bevel stop recess groove wall 17 corresponding thereto.

[0094] 如图9所示,本发明的笔记本电脑的系统端300朝向显示端200的表面上具有用于容置扬声器本体100的容置槽(由于被扬声器本体100遮挡而未示出)。 [0094] As shown in Figure 9, the laptop system of the present invention, the end 300 toward the display main body having a speaker for receiving housing groove (speaker body 100 due to being obscured but not shown) of the upper surface 100 of the end 200. 继续结合图2或图3,扬声器本体2具有顶面和侧面,出音孔9开设在其侧面上,当显示端200转动至与系统端300之间的夹角为O度时,扬声器本体2完全容置于容置槽内,且扬声器本体2的顶面不突出于系统端300朝向显示端200的表面。 Continue in conjunction with FIG. 2 or 3, the speaker body 2 has a top surface and side, the sound hole 9 opened on its side, while the display side and the system side 200 is rotated to the angle between the O 300 degrees, the speaker body 2 completely accommodated in the accommodating groove and the top surface of the body 2 speaker system does not protrude toward the display surface side end 300 200. 本实施例中翻转扬声器100为两个,两个翻转扬声器100对称设置在系统端300朝向显示端200的转动侧的两端。 In this embodiment two inverted speaker 100, the two flip speaker 100 disposed symmetrically at both ends of the rotation-side end 200 of the display 300 toward the system side.

[0095] 下面结合附图对本发明的翻转扬声器以及笔记本电脑的转动过程以及工作原理进行介绍。 [0095] the following with reference to flip the speaker of the present invention and the rotation process and the principle of laptops introduced.

[0096] 首先需要说明的是,实际上扬声器本体2的预定角度可以为任意角度,但考虑到实用性和必要性,本实施例中仅以预定角度在O〜90度(例如60度)范围内为例进行说明。 [0096] first need to explain that, in fact predetermined angle speaker body 2 may be any angle, but taking into account the practicality and necessity, for example, in O~90 degree (for example, 60 degrees) only a predetermined angle range of the present embodiment within example.

[0097] 如图11所示,当显示端200处于O度时,扬声器本体2位于系统端300的容置槽内,按压部11与开关10接触,使扬声器本体2处于禁声状态,第一齿轮4右侧(所谓右侧,是指图中的右侧,以下同)的齿与第一齿部7上的右侧的齿处于啮合状态;第二齿轮5右侧的齿与第二齿部8上的右侧的齿处于啮合状态;而左侧均处于未啮合状态,随着显示端200的转动,带动第一齿轮4转动并驱动齿条6朝向第二齿轮6 (或扬声器本体2)的方向移动,齿条6在移动的过程中带动第二齿轮5转动,使扬声器本体2转动随之转动,扬声器本体2上的出音孔9露出,并且齿条6上的按压部11脱离开关10,扬声器本体2由禁声状态切换至允许发声状态。 [0097] 11, when the display terminal 200 is O degrees, speaker body system side in FIG. 2 is receiving slot 10 contacts the pressing portion 11 of the switch 300, the speaker sound body 2 in the state ban, first gear 4 on the right (the so-called right-hand, refers to the right side in the figure, hereinafter the same) of the teeth 7 on the right side of the teeth of the first gear portion in engagement; 5 to the right of the second gear teeth and second teeth 8 teeth on the right side portion in engagement; and on the left are not engaged in the state, with the rotation of the end 200 of the display, rotation of the first drive gear 4 and drive towards the second gear rack 6 6 (or speaker body 2 ) The direction, the rack 6 drive in the process of moving the second gear 5 rotates, the speaker will rotate the body 2 is rotated, the sound hole 2 on the speaker body 9 is exposed, and the pressing portion 11 of the rack 6 from switch 10, the speaker body 2 is switched from the state to allow sound gag status. 扬声器本体2最后转动至如图12所示的状态。 The last speaker body 2 is rotated to the state shown in FIG. 12. 在该转动过程中扭簧释放积蓄的扭力(如何积蓄扭力将在下面介绍)。 In this release accumulated during the rotation of the torsion spring torque (torque how savings will be described below).

[0098] 当扬声器本体2转动至预定角度60度时,由于第一齿轮4上仅设置局部齿,该齿已脱离与齿条6的啮合,继续转动显示端200时将不再驱动齿条6移动,使得第二齿轮5也不再被驱动,扬声器本体2便保持在预定角度不动。 [0098] When the speaker body 2 is rotated to a predetermined angle of 60 degrees, since the first gear is provided only partial teeth 4, which has been out of engagement with the rack teeth 6, continue to rotate the display side 200 will no longer drive rack 6 mobile, so that the second gear 5 is no longer driven, speaker body 2 is maintained at a predetermined angle does not move. 如图13所示,显示端200可转动至需要的任何工作角度(如150度)。 As shown in Figure 13, display terminal 200 may be rotated to any desired working angle (e.g. 150 degrees).

[0099] 在上述状态下,如果关闭显示端200,当显示端200关闭至60度时,第一齿轮4上的齿又与第一齿部7相嗤合,并带动齿条6和第二齿轮5动作,实现第二齿轮5和扬声器本体2的转动,实现扬声器本体2的关闭。 [0099] Under these conditions, if you turn off the display terminal 200, when the display terminal 200 close to 60 degrees, the teeth 4 on the first gear and the first gear unit 7 with laugh together, and promote the rack 6 and the second gear 5 actions to achieve the second gear 5 and the speaker body rotation 2, to achieve speaker body closed 2. 在此过程中,扭簧积蓄扭力。 In this process, the torsion torque savings.

[0100] 当显示端200处于工作角度,而使用者只想关闭扬声器,如图14和图15所示,只需按压并翻转扬声器本体2,使扬声器本体2处于小于O度的某一角度,例如负5度(此过程,扭簧积蓄扭力),第二齿轮5在扬声器本体2的带动下反向转动并驱动齿条6向第一齿轮4的方向移动,齿条6上的按压部11触碰开关10,同时止挡件卡入齿条6的止挡槽17内,挡住齿条6,使其不能继续移动,从而实现了显示端200处于工作角度时,能够单独关闭扬声器本体2,使其处于禁声状态。 [0100] When the display terminal 200 is in the working angle, and the user just off the speaker, as shown in Figure 14 and Figure 15, simply press and flip the speaker body 2, the speaker body 2 is smaller than O degrees at an angle, For example minus 5 degrees (this process, the torsion spring torque savings), the reverse rotation of the second gear 5 and driving the rack 6 is moved in the direction of the first gear 4 is driven by the speaker main body 2, the pressing portion 11 on the rack 6 Touch switch 10, while the card into the rack and the stopper member 6 of the stopper groove 17, blocking the rack 6, it can not continue to move, in order to achieve the display 200 when in the operating angle end, the speaker main body 2 can be turned off separately, it is the sound state ban.

[0101] 在图14所示的状态下,如果使用者想关闭显示端200,在最初的转动过程中,由于第一齿轮4与第一齿部7不啮合,显示端200的转动不会引起齿条6的任何动作,如图16和图17所示,当显示端200转动至5度时,第一齿轮4上的推抵部13转动至止挡片15处,并随着第一齿轮4的转动推抵止挡片15,使其脱离止挡槽17,解除对齿条6的止挡。 [0101] In the state shown in FIG. 14, if the end user wants to turn off the display 200, the initial rotation, since the first gear 4 and the first tooth portion 7 is not engaged, the display 200 does not cause rotation of the end Any action of the rack 6, 16 and 17, when the display terminal 200 to 5 degrees of rotation, pushing against the portion 4 of the first gear 13 is rotated to the stopper piece 15, and with the first gear 4. Push the rotation against the stopper plate 15, away from the stopper grooves 17, the lifting of the stopper on the rack 6. 扭簧释放扭力,在扭簧的扭力作用下,第二齿轮8反向转动,齿条6则在第二齿轮8的带动下朝向第二齿轮8的方向运动,当运动到扬声器本体2处于O度时,齿条6被第一齿轮4上的齿挡住并限位而恢复至图11所示的初始状态。 Torsion spring release torque at the torsion of the torsion spring, and the second gear 8 reverse rotation, the rack 6 toward the direction of movement of the second gear 8 is driven by the second gear 8, when the motion to the speaker body 2 in O When the degree of the rack teeth 4 6 is blocked on the first gear and the stopper 11 and returned to the initial state shown in FIG.
