A speaker includes a frame having a receiving space, a vibration unit received in the receiving space, and a magnetic circuit unit for driving the vibration unit to vibrate and emit sound. The vibration unit includes a first diaphragm configured to vibrate and emit sound, and a voice coil for driving the first diaphragm to vibrate and emit sound. The speaker further includes a centering support sandwiched between the first diaphragm and the voice coil. In the speaker according to the present disclosure, by sandwiching the centering support between the voice coil and the first diaphragm, a positional conflict between the centering support and the main magnet is avoided, the main magnet can have an increased size, thereby enhancing the space utilization and sensitivity of the speaker, and improving the acoustic performance of the speaker.

Provided is a speaker, including a holder, a vibration unit, and a magnetic circuit unit. The vibration unit includes a first diaphragm and a voice coil, and the voice coil includes a voice coil lead wire. A centering support is sandwiched between the first diaphragm and the voice coil, and includes a first pad portion. The magnetic circuit unit has a recessed portion formed at a position corresponding to the first pad portion. In the speaker provided by the present disclosure, the magnetic circuit unit is provided with the recessed portion to increase the distance between the magnetic circuit unit and the first pads, so that the vibration amplitude of the voice coil can be increased, thereby improving the acoustic performance of the speaker, and providing operating space for the subsequent welding process.

A speaker includes: a frame, a vibration system fixed to the frame, including a diaphragm fixed to the frame and a voice coil driving the diaphragm to vibrate and emit sounds, and a magnetic circuit system fixed to the frame, wherein the diaphragm includes a dome and a suspension surrounding and connected with the dome, the dome includes a first metal dome with a through hole and a second dome covering the through hole, the first metal dome is located between the suspension and the second dome, and the first metal dome is fixedly connected with the suspension and the second dome. Compared with the related art, the speaker disclosed by the present disclosure has higher high frequency performance.

Provided is a waterproof sound device including: an acoustic unit that emits or receives sound; and a membrane that vibrates to transmit the sound emitted from the acoustic unit to the outside or to transmit sound from the outside to the acoustic unit, wherein a distance from the membrane to the acoustic unit is determined to be greater than the maximum vibration width of the width of the vibration of the membrane that vibrates toward the acoustic unit.

An apparatus including a transducer configured to generate sound, where the transducer comprises a diaphragm. At least one portion of the transducer is electrically conductive and is configured to provide an electrical connectivity to a ground. The at least one portion, at least in part, circumferences the diaphragm.

A loudspeaker including a chassis, a drive unit and a diaphragm. The drive unit has a stationary part secured to the chassis and a translatable part secured to the diaphragm. An outer edge of the diaphragm is suspended from the chassis by an edge suspension. The edge suspension has a plurality of straight portions, each straight portion having a respective first surface and a respective second surface which meet along an edge to provide a spring which permits the diaphragm to be moved relative to the chassis by the drive unit. The edge suspension has at least one corner portion, wherein the/each corner portion joins two of the straight portions together and includes at least one geometrical interruption formed therein.
