Loudspeaker with damping function

Abstract

The invention discloses a loudspeaker with a damping function. The loudspeaker comprises a shell, a basket and an underframe, wherein the shell is a circular truncated cone shape, and the internal ofthe shell is in a cavity state; the upper bottom surface of the shell is in a through state, and the lower bottom surface of the shell is in a sealing state; the underframe is formed by two cylinderswhich are called as a first cylinder and a second cylinder; the section area of the first cylinder is greater than that of the second cylinder, and the second cylinder is located at the center of thefirst cylinder, and penetrates the first cylinder; the internal of the second cylinder is in a hollow state; a vibrating diaphragm, a dustproof cover, a spider, a voice coil and a permanent magnet arearranged in the shell; a damping device is arranged at the top of the shell, and one connection is formed between the damping device at the top of the shell and the basket and the underframe, and theunoccupied parts of the internal edge and bottom of the shell are filled with a damping material. The invention provides a loudspeaker capable of achieving the damping effect.

Description

technical field [0001] The invention belongs to the technical field of loudspeaker manufacturing technology in integrated circuits, and in particular relates to a loudspeaker with a shock-absorbing function. Background technique [0002] Loudspeaker is also called "horn"; it is a very commonly used electro-acoustic transducer device, which can be seen in electronic and electrical equipment that emits sound; with the rapid development of electronic information technology, more and more electronic products are applied to Loudspeakers are used as their sound-generating components, such as mobile phones, laptops, etc. Nowadays, people have put forward higher requirements on the acoustic performance of the speaker; the speaker of the related technology structure mainly includes a casing and a sound-generating device accommodated in the casing. In order to improve the sound quality, the usual practice is to Filled with sound-absorbing materials such as zeolite molecular sieves, b...

Problems solved by technology

Nowadays, people have put forward higher requirements on the acoustic performance of the speaker; the speaker of the related technology structure mainly includes a casing and a sound-generating device accommodated in the casing. In order to improve the sound quality, the usual practice is to Filled with sound-absorbing materials such as zeolite molecular sieves, but the skeleton structure of zeolite or molecular sieve is mainly composed of silicon or silicon-alumina, which has a great adsorption capacity for nitrogen in the air, but has a limited adsorption capacity for oxygen in the air, maki...
