Ultra-thin trumpet

Abstract

The invention discloses an ultra-thin trumpet. The ultra-thin trumpet comprises a basin frame, drum paper, a voice coil and a magnetic component, wherein the drum paper is positioned at the bottom of the base frame and encloses to form an accommodating cavity; the bottom of the voice coil is fixedly connected with the drum paper; the upper part of the voice coil is electrically connected with a polyamide yarn; the magnetic component comprises an outer cover and a magnetic route arranged on the inner side of the outer cover; the outer cover is provided with a top part and a ring part; the magnetic route and the ring part enclose to form an annular space; the upper part of the voice coil is positioned in the annular space; for an interface position of the voice coil, connected with the polyamide yarn, a first concave notch for avoiding during vibration of the polyamide yarn is formed in the ring part; the drum paper comprises a body in the middle and two folding rings at the periphery; the two folding rings are bonded with each other; the outer end edges of the two folding rings are bonded with each other and are bonded with the basin frame; the inner end edges of the two folding rings are bonded with the edge of the body; the two folding rings are sunk in the accommodating cavity; an air cavity is formed between the two folding rings; and vents for communicating the air cavity with the external air are formed in at least one folding ring. Therefore, the overall height of the trumpet can be greatly reduced.

Description

technical field [0001] The invention relates to the technology in the field of audio equipment, in particular to an ultra-thin speaker. Background technique [0002] With the rapid development of science and technology and people's needs for life, speakers have been widely used in electronic devices such as televisions, computers, and mobile phones. [0003] Existing loudspeakers generally include pot frame, drum paper, voice coil, elastic wave and magnetic components, etc., and a terminal board is arranged on the pot frame, and the terminal board is connected to the voice coil through brocade wire. When the audio current flows through the brocade wire through the voice coil At this time, the voice coil is subjected to the magnetic field force of the magnetic component to produce a corresponding repeated movement, thereby driving the drum paper and the voice coil to generate piston-like vibration, and then pushing the surrounding air to produce sound. [0004] Due to the li...

AI Technical Summary

Problems solved by technology

This will make it difficult to reduce the overall height of the speaker, and cause the speaker to be assembled into the electrical equipment to take up more space in thickness

In addition, when assembling, this kind of traditional horn must be combined with elastic wave and drum paper respectively, which is cumbersome to assemble.
