Abstract: A speaker includes a telescopic sound chamber, a first diaphragm, and a first piezoelectric vibrating element. The telescopic sound chamber has a box wall, a bottom layer, and a first opening. The telescopic sound chamber includes a plurality of telescopic sub-box layers sleeved on and connected to each other and decreasing in volume layer by layer. The telescopic sound chamber accommodates the smaller telescopic sub-box layer into the larger telescopic sub-box layer to reduce the volume of the telescopic sound chamber. The telescopic sound chamber moves the smaller telescopic sub-box layer away from the larger telescopic sub-box layer to increase the volume of the telescopic sound chamber. The first diaphragm is arranged on the box wall to cover the first opening. The speaker can improve the drawbacks of low-frequency range distortion and has the advantages of full audio, high volume, and smooth sound pressure.

Abstract: The present invention provides a coaxial speaker including a fixing member, a magnetic circuit system, a voice coil, a first vibration system connected with the voice coil, and a second vibration system connected with the voice coil and arranged surrounding the first vibration system. The second vibration system locates coaxially with the first vibration system. The first vibration system includes a first diaphragm and a first support connecting the first diaphragm and the voice coil. The second vibration system includes a second diaphragm and a second support connecting the second diaphragm and the voice coil. The first diaphragm is used for generating treble sound. The second diaphragm is used for generating bass sound. Bass sound and treble sound form a full-range speaker, providing high-quality sound. Moreover, the assembly process is simplified by sharing voice coil, which improves assembly efficiency and reduces costs.
