Embodiment 1

It is a kind of bluetooth-type labyrinth speaker in the present embodiment in figure, for common Baffle Box of Bluetooth due to size with reference to Fig. 1 Low frequency dive caused by limitation with loudspeaker size is insufficient, and the not no powerful situation of sound passes through the Acoustic Optimization of labyrinth channel It is made up.

Specifically, bluetooth-type labyrinth speaker includes cabinet 10, bluetooth receiving module, decodes amplification module and loudspeaker 12, Bluetooth receiving module, decoding amplification module and loudspeaker 12 are sequentially connected.Mounting hole is offered on 10 front panel of cabinet, is being installed Loudspeaker 12 is set on hole, offers pilot hole 13, side and pilot hole of the loudspeaker 12 inside cabinet 10 on cabinet 10 Labyrinth channel is formed between 13, i.e., a part of low frequency generated when loudspeaker 12 works ensure that use after labyrinth channel Low frequency dive of person during listening increases the volume of 40Hz or less ultralow frequency.

Labyrinth channel includes the first serpentine channel 21 close to loudspeaker 12, bluetooth receiving module and decoding amplification module 11 It is connected in cabinet 10 and respectively at the top and bottom of cabinet 10, bluetooth receiving module and decoding amplification module 11 limit jointly Second serpentine channel 22.

Further, the first serpentine channel 21 extends in vertical direction, bluetooth receiving module and decoding amplification module 11 It is arranged along the vertical direction, the second serpentine channel 22 is horizontally extending.

Pilot hole 13 is opened on the front panel of cabinet 10, and pilot hole 13 is located at 12 bottom of loudspeaker.Pilot hole 13 is opened It is conducive to low frequency set on bottom directly to export, when bluetooth-type labyrinth speaker is arranged by wall, reduces the resonance that metope generates, promote sound Matter.It should be noted that above-mentioned pilot hole 13 can also open up and 10 rear side of cabinet in other specific embodiments.

It optionally, further include acoustic chamber 23 in cabinet 10, acoustic chamber 23 and loudspeaker 12 are close to the side of cabinet 10 It is corresponding, several protrusions are equipped in acoustic chamber 23.Sound wave is by the protrusion in acoustic chamber 23, by multiple reflections, according to Principles of Acoustics make high frequency signal decay, and then obtain more 40Hz low frequencies below, export by labyrinth channel.

Bluetooth-type labyrinth speaker in the present embodiment, which overcome the limitation of speaker volume and power, reasonable disposition cabinets Structure in 10 increases sound quality to obtain better low frequency dive.

The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
