Description

technical field

[0001] The invention belongs to the technical field of loudspeakers, in particular to a high-power ultra-thin loudspeaker. Background technique

[0002] With the popularization of notebook computers and LED TVs, many similar electronic products tend to be thinner and lighter. For this reason, speakers used in these electronic products also need to be thinner. However, when the volume of the speaker is reduced, especially when the thickness is reduced, the withstand power of the speaker is correspondingly reduced, so that it cannot meet the usage requirements.

[0003] At the same time, after the volume of the speaker is reduced, the sound quality of the speaker will also be limited. The traditional woofer has a relatively high treble, or when the treble is reduced, the lowest resonance frequency F0 is relatively high, or the power is too small, so it cannot reproduce the low frequency well. Especially the woofer used on the TV set has comprehensive and high...
