Embodiment 1

[0029] This embodiment provides a filter device for audio.

[0030] Please see figure 1 and figure 2 , the filter device 100 includes a separator 110, and a plurality of communication holes 120 opened on the separator 110; the separator 110 includes two sides facing away, and at least one of the sides is provided with a corresponding communication hole 120 The protruding edge 130 of the edge setting. Wherein, the separator 110 may be a sheet metal part, a plastic part, a wood part and the like. The separator 110 may be flat, curved or other shapes. The connection hole 120 is used to communicate with both sides of the filter device 100 so that the sound can be transmitted smoothly. The shape of the communication hole 120 may be a circle, a triangle, a quadrangle, or other polygons and the like. The protruding edge 130 can be integrally formed with the separator 110 , or can be assembled together by bonding, welding or clamping with a copper drum later. The protruding edg...

Embodiment 2

[0041] This embodiment provides a sound.

[0042] Please see Figure 4 , the audio system includes a housing 200 and a speaker 300, the housing 200 is provided with a sound cavity 210, and the speaker 300 is installed in the sound cavity 210; the audio system also includes the filter device 100 as in the above embodiment , the filter device 100 is installed in the sound cavity 210 . For the specific structure of the filter device 100, refer to the above-mentioned embodiments. Since this speaker adopts all the technical solutions of all the above-mentioned embodiments, it also has the effect of reducing the mutual interference between the signals in the speaker, and can especially highlight the low-frequency part of the audio signal. .

[0043] Further, in this embodiment, there are multiple sound cavities 210 , and the filter device 100 is disposed between the multiple sound cavities 210 and communicates with the multiple sound cavities 210 . Therefore, the boundary of the ...

Abstract

The invention discloses a filter device and an audio system. The filter device comprises a partition body and a plurality of communication holes arranged on the partition body. The partition body comprises two back-to-back sides, at least one of which is provided with a protruding edge arranged corresponding to the edge of the communication hole. The invention has the effects of reducing mutual interference of audio signals of sound, highlighting low-frequency partial signals, reducing distortion, strong anti-signal interference ability, increasing bearing capacity, curve equalization, and increasing frequency range.

Description

technical field [0001] The invention relates to the technical field of audio, in particular to a filter device and an audio. Background technique [0002] Existing speakers include sealed speakers and inverted speakers. However, the existing audio structure is prone to the problem of mutual interference of audio signals. Contents of the invention [0003] The main purpose of the present invention is to provide a filter device and a sound box, aiming at reducing the problem of mutual interference of audio signals of the sound box. [0004] In order to achieve the above object, the filter device proposed by the present invention is used for audio, the filter device includes a separator, and a plurality of communication holes opened on the separator; the separator includes two opposite sides, at least One side is provided with a protruding edge corresponding to the edge of the communicating hole. [0005] Optionally, the free end surface of the protruding edge is in the sh...
