Abstract
A coaxial speaker includes a magnetic circuit system, a first sound production unit, and a second sound production unit. The first sound production unit and the second sound production unit are coaxially disposed. The first sound production unit surrounds the second sound production unit. The first sound production unit includes a first vibrating diaphragm and a first voice coil. The first voice coil is configured to drive the first vibrating diaphragm to vibrate and produce sound. The second sound production unit includes a second vibrating diaphragm and a second voice coil. The second voice coil is configured to drive the second vibrating diaphragm to vibrate and produce sound. The coaxial speaker ensures concentricity of the first vibrating diaphragm and the second vibrating diaphragm, reduces a height of related products, and reduces cost of the magnetic circuit system.
