Abstract

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.
