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.
