Problems solved by technology

[0004] However, in the sound-generating device of the related art, the diaphragm and the elastic support assembly are respectively fixed on opposite ends of the voice coil, although the elastic support assembly can effectively prevent the lateral swing of the voice coil when it vibrates, However, the structure directly connected to the voice coil restricts the design of the voice coil. Since the height of the voice coil is fixed, in order to ensure the space for up and down vibration, the overall height of the sound-generating device cannot be thinner. In addition, the The volume of the magnetic circuit system is also limited, and the elastic support assembly is arranged between the voice coil and the magnetic circuit system, which also affects the magnetic gap, so that the magnetic circuit cannot be maximized, so that the The acoustic performance of the sound-generating device is more optimized

Abstract

The invention provides a sound generator, comprising a basin frame, a vibration system, a magnetic circuit system with magnetic gaps and four mutually-spaced support frameworks, wherein the vibrationsystem comprises a diaphragm, a voice coil inserted in the magnetic gaps, and an elastic support component that is fixed on the basin frame and is arranged opposite to the diaphragm at intervals, wherein the voice coil has a rectangular structure with rounded corners, and the four support frameworks are respectively positioned at four rounded corners of the voice coil; and one end of each supportframework is fixed to the elastic support component, and the other end of each support framework is fixed to one end of the voice coil far away from the diaphragm, so that the voice coil is elastically suspended below the diaphragm. Compared with related technologies, the sound generator provided by the invention has excellent acoustic performance and good listening sense.

Description

【Technical field】 [0001] The invention relates to the field of electroacoustic conversion, in particular to a sound generating device used in portable electronic products. 【Background technique】 [0002] With the advent of the mobile Internet era, the number of smart mobile devices continues to rise. Among the many mobile devices, the mobile phone is undoubtedly the most common and portable mobile terminal device. At present, the functions of mobile phones are extremely diverse, one of which is the function of high-quality music. Therefore, sound-generating devices for playing sound are widely used in current smart mobile devices. [0003] The sound-generating device in the related art includes a pot frame, a vibration system fixed to the pot frame, and a magnetic circuit system that drives the vibration system to vibrate and sound. The vibration system includes a diaphragm fixed to the pot frame, drives the vibrating Membrane vibration voice coil and elastic support assem...
