Ultrathin electrodynamic loudspeaker

Abstract

The invention discloses an ultrathin electrodynamic loudspeaker. The ultrathin electrodynamic loudspeaker is characterized by comprising a stand, a magnetizer, a magnet, a concentrating flux plate, a voice coil, a centering disk, a vibrating membrane and a dust cover, wherein the magnetizer, the magnet and the concentrating flux plate are sequentially arranged in a space formed by the stand, the voice coil is arranged between the magnetizer and the concentrating flux plate, the centering disc is arranged on the peripheral surface of the voice coil, the vibrating membrane is arranged on the centering disc and covers both the centering disc and the space of the stand, the dust cover is arranged on the voice coil for masking, the centering disc is characterized by comprising a bottom support part for supporting the bottom of the stand, an lower flank part extends from a inner side terminal part of the bottom support part to an upper part and form a circular lower flank part, and a ripple part horizontally extends from an upper terminal part of the lower flank part to form certain ripples.

Description

technical field [0001] The invention relates to an ultra-thin electric loudspeaker, in particular to an ultra-thin electric loudspeaker which can realize ultra-thin structure and can improve the bass playing function through improvement. Background technique [0002] A speaker (speaker) is an audio device that converts electrical signals into the vibration of the diaphragm, generates density waves in the air, and emits sound waves. [0003] In such a loudspeaker, the following parts are included: a voice coil (voice coil) that flows current due to an external electrical signal, a voice coil bobbin (bobbin) that winds the voice coil, a permanent magnet (magnet) that forms a magnetic field, and a voice coil bobbin that will move up and down. The vibration generated by the movement is emitted to the diaphragm (diaphragm) in the air as sound waves. [0004] The vibrating membrane of the speaker having the above-mentioned structure vibrates according to the Lorentz force (Lorent...

Problems solved by technology

[0009] Therefore, there is a limitation in reducing the overall height (H1) of the conventional small high-output loudspeaker (1) in order to secure the amplitude.

And, from the position of the above-mentioned damper (17), the magnetic permeable plate (11) should be attached on the top of the permeable body (12), so there is a limit to reducing the overall height (H1) structurally
