Ultra-thin speaker system

Abstract

Provided is a super-thin loudspeaker system, comprising an impedance matcher, a loudspeaker unibody and a loudspeaker rear chamber; the loudspeaker unibody is connected between the impedance matcher and the loudspeaker rear chamber; one end of the impedance matcher is seamlessly connected to the loudspeaker unibody, and the other end is a sounding hole end; the cross section of the impedance matcher is a flat cross section; and the sectional area of the flat cross section expands gradually from the seamlessly connected end of the loudspeaker unibody to the sounding hole end. The present invention utilizes structural and acoustical design means and, in a space with limited thickness, enables the loudspeaker to generate a better impedance match with the air in an external space via the impedance matcher with flat cross sections, thereby achieving higher radiation efficiency, thus improving the maximum volume of the loudspeaker of super-thin electronic products.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to an ultra-thin loudspeaker system applied to ultra-thin electronic products. Background technique [0002] With the progress of society and the development of technology, more and more people use access terminals to access the Internet or intranet in a wireless manner to obtain information. in this case, [0003] Home video entertainment equipment such as TV sets require means of sound reproduction, and generally speaking, medium-sized speakers can meet such needs. However, panel-type products such as LCD TVs emphasize making the products thinner. In order to reduce the thickness of the TV case, the miniaturization of the flat-panel TV audio system must be realized. However, in order to reproduce a sufficient volume, the speaker must have a sufficient volume, and it has become difficult to secure a space required for the speaker in the chassis as the flat panel TV has becom...

AI Technical Summary

Problems solved by technology

However, to ensure the sensitivity and maximum power of the direct-firing speaker, larger and thicker magnets are required. At the same time, the vibration of the speaker also requires a necessary range of motion for the vibration module in the speaker. This requirement on efficiency limits the speaker. The miniaturization of the same is not conducive to the size of the compression

[0006] In response to the requirement of miniaturization, rod-shaped direct-firing speakers with side-firing sound have appeared in recent years for use with thin TVs, but the volume of such speakers is often low and cannot meet the sound requirements of TVs used in larger living rooms
