【detailed description】

A micro-sound comprising a main body with a horn; the top of the main body is inclined downward, and the side surface of the main body is curved in a convex shape from the two ends to the middle; the side of the main body is disposed at a position opposite to each other. The first speaker and the second speaker are provided with a third speaker at the top of the body. In the present invention, since the first horn and the second horn are disposed on the side of the arc-shaped main body and the third horn is disposed on the downwardly inclined top, the sound is propagated in the three-dimensional direction to have a better stereo effect.

The invention will now be further described with reference to the drawings and preferred embodiments.

As shown in Figs. 1 to 3, the stereo includes a main body 100 in which a speaker and a main circuit board are disposed, and a base 200 in which a battery and a key circuit board are disposed inside the support main body 100. The main circuit board is electrically connected to the battery, and the key circuit board is electrically connected to the main circuit board. On the base 200 and the main body 100, opposite positions of the wires for passing through the wires are provided.

The top of the main body 100 is inclined downward and the side surface is curved in a convex shape toward the both ends to the middle, and includes a left shell 2 and a right shell 1 and a middle frame 3 connecting the left shell 2 and the right shell 1 and a left shell. 2 and right shell 1 The middle frame 3 is detachable and fixed between the three. The left shell 2/right shell 1 is generally convex outwardly convex and has a semicircular opening at the bottom and a downwardly inclined slit at the upper end; the middle frame 3 includes a closed left shell 2 and a right shell 1 a first closed end of the upper end cut and a second closed end closing the left shell 2 and the bottom of the right shell 1 and a support column disposed between the first closed end and the second closed end; the relative of the left shell 2 and the right shell 1 A horn limiting ring is disposed at each position, and the first horn and the second horn are respectively fixed in the horn limiting ring by glue, and a horn sounding hole 5 for sounding is disposed in the horn limiting ring; The upper closed end of the third end is provided with a first escaping position 31 adapted to the third horn, and the upper closed end is provided with a concave horn placing table 32 for ringing the first escaping position 31, and the third horn is fixed by glue On the horn placement table 32. In this embodiment, the first speaker and the second speaker adopt the same type of speaker, and the third speaker adopts the film type speaker and is larger than the first avoidance position 31, and the thin film type speaker is light in weight and does not appear to be caused by the top of the main body being overweight. Poor stability, small size, does not take up too much space.

Since the third speaker is exposed outside the main body, in order to protect the third speaker, the micro-speaker further comprises a speaker net 4 covering the third speaker and closely cooperating with the Laba placing table, and the edge of the speaker net 4 is provided with the The placing table is closely fitted to the insertion portion 41. In order to enhance the strength of the horn mesh 4, an outwardly inclined fold 42 is provided between the insertion portion 41 and the horn mesh 4. The inclination of the louver placement table 32 is the same as the inclination of the first closed end. Thus, the distance between the table 8 and the top of the middle frame 3 is the same, which is convenient for injection molding.

The micro-audio further includes a button 6 for controlling the button circuit board disposed in the base 200. In order to facilitate the installation of the button, the button 6 is set in an integrated manner, and a button avoidance hole corresponding to the button 6 is disposed on the base.

The above is a further detailed description of the present invention in connection with the specific preferred embodiments. It is not intended that the specific embodiments of the invention are limited to the description. It will be apparent to those skilled in the art that the present invention may be practiced without departing from the spirit and scope of the invention.
