It filtering device 100 provided by the present embodiment when in use will be in the installation to sound equipment of filtering device 100；Work as sound equipment
When interior propagation sound, sound is separated by the intercommunicating pore 120 on filtering device 100 so that audio signal is filtered,
Reduce interfering with each other between signal, it is particularly possible to which the low frequency part signal in prominent audio, effect are as shown in Figure 3.And
From figure 3, it can be seen that the sound equipment using the present embodiment has the advantages that
1, the audio signal for reducing sound equipment interferes with each other, prominent low frequency part signal；
2, distortion reduction, antinoise signal interference performance is strong, and bearing capacity increases；
3, curve is balanced, the increased effect of bandwidth range.
Therefore, filtering device 100 provided by the present embodiment passes through the protrusion of the edge setting in corresponding intercommunicating pore 120
Edge 130.So as to reduce interfering with each other between signal, the audio of sound equipment is improved.
Specifically, in the present embodiment, the free end face at the prominent edge 130 is in contour planar.To have
The easy to process and preferable effect of filtered audio effect.Certainly, in other embodiments, the free end face at prominent edge 130
It is also possible to wavy etc..
Specifically, in the present embodiment, multiple intercommunicating pores 120 are adjacently positioned along left and right directions, and each institute
The lower edges for stating intercommunicating pore 120 are disposed adjacent with the lower edges of the spacer body 110 respectively.So as to the company of being evenly arranged
Through-hole 120, so that multiple intercommunicating pores 120 being capable of uniform filtering audio signal.
Specifically, in the present embodiment, 120 triangular shape of intercommunicating pore.So that filtered audio effect is more preferable,
Low frequency part signal is more prominent.
Specifically, in the present embodiment, 120 triangular shape of intercommunicating pore.The intercommunicating pore 120 is at an acute angle to be set upward
The isosceles triangle shape set.So that filtered audio effect is more preferable, low frequency part signal is more prominent.
Embodiment two
Present embodiments provide a kind of sound equipment.
Fig. 4 is please referred to, the sound equipment includes shell 200 and loudspeaker 300, and sound chamber 210 is equipped in the shell 200, described
Loudspeaker 300 are installed in the sound chamber 210；The sound equipment further includes the filtering device 100 such as above-described embodiment, the filter
Part 100 is installed in the sound chamber 210.The specific structure of the filtering device 100 is referring to above-described embodiment, since this sound equipment uses
Whole technical solutions of above-mentioned all embodiments, therefore also have and reduce interfering with each other between signal in sound equipment, especially may be used
To protrude the effect of the low frequency part signal in audio.
Further, in the present embodiment, the quantity of the sound chamber 210 is multiple, and the filtering device 100 is set to multiple
Between the sound chamber 210, and it is connected to multiple sound chambers 210.So that passing through 100 shape of filtering device between adjacent tone chamber
The boundary of audio chamber, and then achieve the effect that filter the audio signal in each sound chamber 210.
Specifically, sound chamber 210 can be cuboid shape, it can also be with other shapes.Such as shown in Fig. 5, one of sound chamber
210A is in cuboid shape, another sound chamber 210A is in irregular.
Further, in the present embodiment, the loudspeaker 300 include active loudspeaker 310 and passive loudspeaker 320；It is described to have
Source loudspeaker 310 and passive loudspeaker 320 are respectively arranged on different sound chambers 210, and are connected to by the filtering device 100.At this
In embodiment, due to being equipped with filtering device 100, audio signal is filtered, and interferes with each other smaller, therefore passive loudspeaker
320 can obtain less, the low frequency part signal sound driver more outstanding of interference, to generate better audio.
Further, in the present embodiment, 210 quantity of sound chamber is three, and inline；
The filtering device 100 is equipped between two adjacent sound chambers 210.
It is equipped with the active loudspeaker 310 in the sound chamber 210 on both sides, is located in the middle in sound chamber 210 and is equipped with institute
State passive loudspeaker 320.
In the present embodiment, sounding power is increased to improve sound source by two active 310 sounding of loudspeaker.And
The sound wave that two active loudspeaker 310 generate is reached at passive loudspeaker 320 by respective filtering device 100, so that passive loudspeaker
The driving energy of 320 acquisitions is bigger, and the bass effect of generation is more preferable.Specifically, relative to conventional sound equipment framework, such as it is closed
Formula case and inverted phase type case, sound equipment provided by the present embodiment, lowest resonance point can go to 1/3fo point, and use conventional structure
The sound equipment of frame will frequency of occurrences wild effect below 1/2fo point.Sound equipment provided by the present embodiment can guarantee sound
Stablize output, harmonic distortion THD can also stablize to be exported near 1%, forms stable fan-out capability.
Further, in the present embodiment, the active loudspeaker 310 and passive loudspeaker 320 are arranged towards same direction.From
And sound is enabled to propagate facing one direction, achieve the effect that sound is more concentrated.It certainly, in other embodiments can be with
Using other schemes.As shown in fig. 6, active loudspeaker 310B and passive loudspeaker 320B is towards different directions.
To sum up, the improvement in sound equipment provided by the present embodiment about filtering device 100, can be adapted for existing speaker
Main frame, such as closed case and inverted phase type case.Also, with the continuous improvement that user requires sound quality, development cycle contracting
It, can be preferably by control loudspeaker linear for the filtering device 100 is increased under each mode state of existing speaker in the case where short
Work, can effectively change frequency response when speaker voice output in range, make it response is more balanced, stereovision is distinct,
Frequency range broadens, dynamic is more prominent, and preferably matches electronic solution.
