Special-shaped ultrathin high-power double-positioning loudspeaker

Abstract

A special-shaped ultrathin high-power double-positioning loudspeaker relates to the technical field of loudspeakers and comprises a vibrating diaphragm, a voice coil, a support, a centering disk, U iron and a magnetic circuit system arranged in the support which are sequentially arranged from top to bottom, and an installation space for installing the voice coil and the magnetic circuit system is arranged in the support in an up-down penetrating mode, the upper end portion of the voice coil is fixedly connected with the lower surface of the vibrating diaphragm, the lower end portion of the voice coil is fixedly connected with the upper surface of the centering disk, and the centering disk is fixed on the support. The vibration amplitude of the loudspeaker is buffered through the centering disk, it is guaranteed that the voice coil keeps vertical linear vibration during vibration, the hidden danger of bottoming caused by oblique vibration and overlarge stroke when high-power voltage is input into the loudspeaker is solved, so that the aims of thinness and high power of the product are fulfilled.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a special-shaped ultra-thin high-power double-positioning loudspeaker. Background technique [0002] The loudspeaker is a transducer device that converts electrical signals into acoustic signals, and the performance of the loudspeaker has a great influence on the sound quality. The loudspeaker is the weakest device in the audio equipment, and it is the most important part for the sound effect; in portable electronic equipment such as portable mobile communication terminal equipment, notebook computers, MP3 players, there are micro A speaker module that converts electrical signals into audio signals. [0003] Existing audio terminal equipment requires small size, portability, and thinness; the size limit of the finished product has led to the development of thinner speakers, and the performance requirements for speakers are also more stringent, requiring small size, ultra-th...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the loudspeaker in the prior art is too large in size and too thick to match the existing terminal audio products. Due to the size limitation, the vibration system has no stroke space, and the disadvantage of bottoming will appear when the power is increased. If the thickness of the traditional speaker is thin, the bass cannot be played out. The body of the flat-panel speaker can be made thin, but the technical defect of low power
