Abstract
The invention, which is suitable for the technical field of the loudspeaker, provides a coaxial moving-coil loudspeaker and a headset. The coaxial moving-coil loudspeaker comprises a substrate, a bracket, an internal magnetic pole loop and an external magnetic pole loop, and a sounding assembly. The internal magnetic pole loop and the external magnetic pole loop are connected with the substrate electrically. The sounding assembly consists of a vibrating membrane, an inner voice coil and an outer voice coil. The internal magnetic pole loop is arranged inside the inner voice coil and the external magnetic pole loop is arranged inside the outer voice coil. When receiving signals, the substrate uses an internal frequency-division network to divide the signals into a high-frequency signal and a low-and-intermediate-frequency signal; the divided high-frequency signal is inputted into the inner voice coil and drives the vibrating membrane to vibrate by the internal magnetic pole loop; and the divided low-and-intermediate-frequency signal is inputted into the outer voice coil and enables the vibrating membrane to vibrate under the magnetic force effects of the external magnetic pole loop and the outer voice coil. Therefore, a two-divided-frequency loudspeaker effect is realized in one single loudspeaker and the segmentation vibration of the vibrating membrane is reduced to improve the tone quality.
