Compound voice diaphragm group

Abstract

The invention discloses a compound sound film group comprising a voice diaphragm and a voice coil, wherein the voice coil is fixed on one surface of the voice diaphragm, and the voice coil is a plane-type single-layer coil spirally and tightly coiled by an enamelled wire; thereby, the voice diaphragm is formed by the plane-type single-layer coil spirally and tightly coiled by the enamelled wire, and the voice coil is compounded and shaped on the surface of the voice diaphragm; the height of the voice coil depends on the diameter of the enamelled wire so that the overall thickness of the compound sound film group is greatly reduced; simultaneously, gaps do not need to be arranged among magnetic circuits of the voice coil, thus, the contour dimensions of a horn and a receiver can be made smaller so as to meet the demand that electronic products in electronic product markets are miniaturized; moreover, the impedance can be directly and easily regulated according to the coiled number of turns of the coil and the diameter of the enamelled wire and is not limited, which is beneficial to all-frequency band passing and offers powerful support to manufacture the horn or the receiver with better tone quality and frequency response characteristic.

Description

technical field [0001] The invention relates to the technology in the field of electronic components, in particular to a composite sound membrane group applied to micro speakers or receivers. Background technique [0002] Both the speaker and the receiver are actually a conversion device that converts electrical energy into sound. The sound film group is the main component of this conversion device. The sound film group includes a voice coil and a sound film. When different electronic energies are transmitted to When the voice coil is used, the voice coil generates an energy that interacts with the magnetic field of the magnet. This interaction causes the sound film to vibrate. Because the electronic energy changes at any time, the voice coil will move forward or backward, so the sound film will move accordingly. The action changes the density of the air to produce sound. [0003] There are roughly two traditional ways to make a sound film group: one is to wind the enameled...
