Problems solved by technology

When the micro-sounder is working, both the sound membrane and the voice coil will vibrate, and with the increase of the working time of the micro-sounder, it is easy for the voice coil to separate from the sound film, causing the micro-sounder to malfunction and fail to work
At the same time, since the voice coil and the sound film need to be bonded with glue after being made separately, the whole process of making the micro-speaker is more complicated.

Embodiment Construction

[0024] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0025] Such as Figure 1-Figure 7 As shown, a kind of miniature sound generator provided by the present invention includes a basin frame 5 and a vibration system and a magnetic circuit system fixed on the basin frame 5, wherein the vibration system includes a sound membrane 1 and is fixed under the sound membrane 1. The voice coil 2 that drives the sound membrane 1 to vibrate and produce sound, and the voice coil 2 and the sound membrane 1 are combined by injection molding.

[0026] Specifically, the basin frame 5 can be a ring-shaped structure made of plastic and other materials and has a housing space; in the vibration system, the sound membrane 1 can be a film-like structure made of metal materials, polymer materials, etc. It can also be provided with structures such as reinforcing ribs to enhance the structural strength o...

Abstract

The invention relates to the technical field of loudspeakers, and in particular relates to a miniature sounder and electronic equipment. The provided miniature sounder comprises a basin stand, a vibration system and a magnetic circuit system; the vibration system and the magnetic circuit system are fixedly connected to the basin stand; the vibration system comprises a voice diaphragm and a voice coil; the voice coil is fixed below the voice diaphragm, and used for driving the voice diaphragm to vibrate and produce sound; and the voice coil and the voice diaphragm are combined through injection moulding. The voice coil and the voice diaphragm of the miniature sounder provided by the invention are difficultly separated; and furthermore, the manufacturing process is relatively simple.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a miniature sound generator, and also to an electronic device. Background technique [0002] With the development of science and technology, people's life is changing with each passing day. In particular, various electronic products have gradually become an indispensable part of people's work and life. Most electronic devices, such as mobile phones, tablet computers and notebook computers, are usually equipped with speakers that convert electrical signals into sound. A device that repeatedly pushes air to generate sound waves. For example, a micro sounder is a small speaker. [0003] At present, people usually use glue to connect the voice coil and the sound membrane together, so that when the voice coil vibrates, it can drive the sound membrane to vibrate together. Because when the micro-sounder is working, both the sound membrane and the voice coil will vibrate, and wi...
