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

Embodiment Construction

[0030] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] The horn speaker is a commonly used speaker, which consists of two parts: a vibration system (treble head) and a horn (impedance matcher). The diaphragm of the vibration system is a dome-shaped diaphragm, and the horn is a trumpet-shaped pipe with a gradually expanding area. The vibration of the diaphragm radiates sound waves into the air through the horn (after two reflections), and continues with the help of a gradually expanding horn-shaped pipe. Amplifies the sound signal output from the speaker. It has high frequency and large volume, and is often used for outdoor and square sound reinforcement. However, due to its horn-shaped pipe structure, the traditional horn-type loudspeaker is often bulky and has not been used in the field of ultra-thin electronic products such as flat-panel televisions.

Abstract

The invention provides an ultra-thin speaker system. The ultra-thin speaker system comprises an impedance matcher, a speaker monomer and a speaker rear cavity, wherein the speaker monomer is connected between the impedance matcher and the speaker rear cavity, one end of the impedance matcher is seamlessly connected with the speaker monomer, and the other end of the impedance matcher is used as a sound outlet end; and the section of the impedance matcher is flat, and the sectional area of the flat cross is gradually extended from the seamless connection end between the speaker monomer and the flat section to the sound outlet end. According to the ultra-thin speaker system, better impedance matching between a speaker and air in an external space can be generated and higher radiation efficiency can be achieved in a space with limited thickness by utilizing the structure and acoustic design means as well as the impedance matcher with the flat section, so that improvement on the maximum volume of the speaker of ultra-thin electronic products is facilitated.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to an ultrathin loudspeaker system applied to ultrathin electronic products. Background technique [0002] With the progress of society and the development of technology, people increasingly use access terminals to access the Internet or internal networks of enterprises in a wireless manner to obtain information. under these circumstances, [0003] Home video entertainment equipment such as TV sets need sound reproduction means, 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 cabinet, it is necessary to realize the miniaturization of the flat-panel TV audio system. However, in order to reproduce sufficient volume, the speaker must have a sufficient volume, and as flat-panel TVs have become thinner, it has become difficult to secure the ...
