Abstract: The invention disclose a single-shrapnel bone conduction oscillator, comprising an embedded shrapnel-type bracket, a first combined bracket being snap-connected to a middle of a top of the embedded shrapnel-type bracket, and a second combined bracket being snap-connected an inside of the embedded shrapnel-type bracket, a voice coil being sleeved on an outer surface of the second combined bracket, a washer being placed inside the voice coil, a magnet being placed on a bottom portion of the washer, and a U-CUP being snap-connected to an bottom portion of the embedded shrapnel-type bracket. The invention has a simple structure. The invention adopts the single-shrapnel type design provided, when the oscillator adds an electric signal, the first combined bracket is fixed with the front shell of the headset to generate vibration, and the magnetic circuit is fixed in the embedded shrapnel bracket.

Abstract: The present invention provides a Bluetooth headset speaker, comprising a bracket, a diaphragm, a voice coil, a washer, a magnet, a U cup, a pad, a first tuning cloth, and a second tuning cloth, wherein the first tuning cloth is fixedly connected to the one side outer wall of the bracket, the one side outer wall of the bracket corresponding to the first tuning cloth is symmetrically provided with through grooves, a through hole is opened on the one side outer wall of the bracket, the second tuning cloth is fixedly connected to one side outer wall of the through hole. Compared with the existing headset speakers, the pad designed by the present invention is internally welded and does not need to be covered with glue, which not only can effectively reduce the production process, but also improves the simplicity of the appearance of the speaker and improves the integration degree of the overall structure of the speaker.
