Embodiment Construction

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Several embodiments of the invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time. The terms "vertical", "horizontal"...

Abstract

The invention provides an electroacoustic device and electronic equipment adopting the electroacoustic device. The electroacoustic device comprises a vibration system, a magnetic circuit system and abracket system for accommodating the vibration system and the magnetic circuit system, the vibration system comprises a vibrating diaphragm, a middle paster and a voice coil. The magnetic circuit system comprises magnetic steel, a polar plate and a middle hole positioning pin; polar plate on magnetic steel, the polar plate and the magnetic steel are cylindrical; the pole plate and the magnetic steel are coaxial, the support system comprises a support body and a rear cover, the rear cover is fixed to the bottom of the middle of the support body, a first through hole is formed in the middle of the magnetic steel, a second through hole is formed in the middle of the pole plate, the middle hole positioning pin sequentially penetrates through the second through hole and the first through hole and is fixed to the rear cover, and the middle hole positioning pin protrudes out of the pole plate. According to the invention, the problem of interference between the magnetic steel and the voice coil caused by deviation of concentricity of assembly and gluing of the magnetic steel and the bracket during vibration of the vibrating diaphragm can be solved.

Description

Technical field [0001] The invention relates to the technical field of acoustic equipment, in particular to an electroacoustic device and an electronic device using the electroacoustic device. Background technique [0002] Electroacoustic devices are important acoustic components of audio products and are widely used in in-ear headphones, headphones, smart Bluetooth speakers and other equipment. The electro-acoustic device is used to complete the conversion of electrical and acoustic signals. It is an energy conversion device, which mainly includes a bracket system, a vibration system, and a magnetic circuit system. [0003] In the prior art, in order to achieve higher sensitivity, the design distance between the ring magnet and the voice coil is relatively small when the structural size is limited. After the electro-acoustic device undergoes environmental reliability tests such as high temperature and humidity, the glue that glues the magnetic steel is prone to failure, causing t...
