Loudspeakers and how to install them

Abstract

The invention provides a loudspeaker and an installation method thereof, wherein the loudspeaker comprises a shell; a loudspeaker unit, a cover plate and sound absorption powder; wherein the shell comprises an accommodating space; the cover plate is fixed to the shell; the cover plate is used for covering the accommodating space; the loudspeaker also comprises a side plate with a net, a clamping groove is formed in the cover plate; the side plate with the net is inserted into the accommodating space through the clamping groove so as to divide the accommodating space into a first cavity and a second cavity; wherein the loudspeaker single body is accommodated in the first cavity, the second cavity is filled with the sound absorption powder, and the second cavity and the first cavity are isolated by the side plate with the net, so that the sound absorption powder is prevented from entering the first cavity from the second cavity. According to the loudspeaker and the installation method thereof, the shell and the cover plate are fixed and then inserted into the side plate with the net, so that the influence on the sealing performance of the side plate with the net caused by the fixed connection of the shell and the cover plate can be avoided, and the powder leakage rate is reduced.

Description

【Technical field】 [0001] The invention relates to the field of sound and electricity, in particular to a loudspeaker applied to portable electronic products and an installation method thereof. 【Background technique】 [0002] With the rapid development of science and technology, the popularity of audio equipment is getting higher and higher. People's requirements for audio equipment are not limited to video playback, but also require more requirements for the reliability of audio equipment. Especially with the advent of the 4G era, mobile multimedia technology has also developed. Many audio devices have a variety of entertainment functions, such as video playback, digital cameras, games, GPS navigation, etc., and their requirements for the playback sound quality of audio devices are also increasing. high. [0003] In the related art, a loudspeaker, as a commonly used electronic component, is mainly used for playing audio signals. The resonant frequency of the speaker is hig...

AI Technical Summary

Problems solved by technology

Therefore, the filling amount of sound-absorbing powder will affect the low-frequency effect of the speaker box

The traditional retaining wall powder filling method has limited powder filling space, so the amount of sound-absorbing powder filled is limited, which is not conducive to improving the low-frequency effect of the speaker

In addition, because the cover plate and the shell of the speaker are finally welded together by ultrasonic waves, the bonding force between the mesh and the plastic will be greatly affected during ultrasonic welding, which increases the probability of powder leakage
