Abstract

The invention discloses a multi-drive audio module. The multi-drive audio module comprises a vibrating diaphragm component, a voice coil component, a magnetic circuit component, a bracket and a rear cavity cover plate; the vibrating diaphragm component and the rear cavity cover plate are respectively combined and installed in the upper layer and the lower layer of the bracket, so that an inner cavity is formed; both the voice coil component and the magnetic circuit component are arranged in the inner cavity, wherein the voice coil component is connected below the vibrating diaphragm component;the magnetic circuit component is connected above the rear cavity cover plate; and the magnetic circuit component is matched with the voice coil component, so that the vibrating diaphragm component produces sound. Multiple voice coils having the same impedance are connected in series, so that power sharing is carried out; therefore, the power burden of the single voice coil can be reduced while the relatively high power can be obtained; the service life of the voice coil is prolonged; the segmentation vibration of a vibrating diaphragm is reduced; the whole structure is compact; due to the relatively small rear cavity volume, the relatively small product volume and the relatively regular shape can be realized; and the applicability and the competitiveness of a product are improved.

Description

technical field [0001] The invention relates to the technical field of audio equipment, in particular to a multi-drive audio module. Background technique [0002] In a traditional audio module, the speaker is usually placed in a sealed rear cavity to reduce the bad superposition caused by low-frequency diffraction, so as to achieve the best effect. However, a small and airtight rear cavity will reduce the compliance of the diaphragm, resulting in a substantial increase in the low-frequency resonance frequency, making the bass worse, and increasing the quality of the vibration system to reduce the low-frequency resonance frequency will increase the SPL (sensitivity) ) decreases to make the sound smaller. [0003] At the same time, since the power of the voice coil in the speaker depends on the thickness of the wire diameter (note the wire itself) and the wire material, the carrying power of the voice coil wire is limited. The thicker the wire diameter, the smaller the resist...
