Embodiment Construction

[0025] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0026] In addition, if there are descriptions involving "first", "second" and so on in the embodiments of the present invention, the descriptions of "first", "second" and so on are only for descriptive purposes, and should not be interpreted as indicating or implying Its relative importance or implicitly indicates the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of these features. In addition, the meaning of "and / or" appearing in the whole text includes three parallel schemes, taking "A and / or B" as an example, ...

Abstract

The invention discloses a voice coil assembly and a sound production device, the voice coil assembly comprises a voice coil and a voice coil skeleton, the voice coil comprises a voice coil body and avoice coil lead, and the voice coil body is formed by winding an amorphous metal wire; and the voice coil framework is arranged at the inner side of the voice coil. The voice coil assembly is small inunit resistance, and in a sound production device provided with the voice coil assembly, when a current signal is converted and output to sound wave energy, the voice coil loss is small.

Description

technical field [0001] The invention relates to the technical field of electroacoustic conversion, in particular to a voice coil assembly and a sound emitting device. Background technique [0002] With the thinning design of electronic equipment, the space reserved for acoustic modules in existing electronic equipment is getting smaller and smaller. In the acoustic module, it is necessary to supply power to the coil, and the voice coil generates a magnetic field, so that the voice coil drives the diaphragm to vibrate and produce sound. Since the voice coil needs to vibrate with the diaphragm, the voice coil wire requires high tension; at the same time, the resistance of the voice coil increases gradually with the increase of the number of winding turns of the voice coil. The resistance of the existing voice coil wire is relatively large, so that the current signal The loss of the voice coil is large when converting and outputting the sound wave energy. Contents of the inv...
