First embodiment
Fig. 1 and Fig. 2 are please referred to, the utility model embodiment provides a kind of microphone test device 100, which surveys
It includes support plate 110 and loudspeaker 120 that trial assembly, which sets 100, wherein support plate 110 is connect with loudspeaker 120, and support plate 110 and 120 phase of loudspeaker
Pair position be provided at least two placement holes 111, placement hole 111 is for installing microphone to be detected.
Specifically, in the present embodiment, it since producer is when producing microphone, needs to examine the performance of microphone
It surveys, to detect whether microphone is qualified, qualified product is sold, and underproof product then needs first to repair,
It just can be carried out sale after performance is qualified.Meanwhile producer is according to can also further studying birth the problem of underproof microphone
Whether producing line is problematic, to reduce the loss of producer.
And in the prior art, the detection for microphone causes the production cost of producer to increase due to inefficiency
Add.In view of this, the utility model embodiment provides a kind of microphone test device 100, wherein Fig. 3 and Fig. 4 are please referred to,
The support plate 110 of microphone test device 100 is provided at least two placement holes 111, so as to simultaneously at least two microphones
It is detected.By the setting of microphone test device 100, there are two be illustrated for placement hole 111 below, it should be understood that,
In other embodiments, may also set up more placement holes 111, such as 4 placement holes 111 of setting, the present embodiment to this not
Do any restriction.
In the present embodiment, loudspeaker 120 are installed on support plate 110, meanwhile, microphone to be detected is installed in placement hole 111,
The sound issued by loudspeaker 120 receives simultaneously there are two microphone, and divides two received audio signals of microphone
Analysis, thus judge whether two microphones are qualified, meanwhile, two microphones can be also compared, for example, carrying out sound
When frequency signal is analyzed, two microphones are qualified, but the audio signal of one of microphone is significantly better than another microphone
Audio signal, can to two microphone divided ranks, thus make producer production life it is more convenient.
Further, in order to calibrate loudspeaker 120, so that loudspeaker 120 issue the standard voice needed, consequently facilitating detection,
In the present embodiment, microphone detection device further include 170,170 be installed on support plate 110, and 170 connect with support plate 110 170 with
The electrical connection of one intelligent terminal need to make a sound when needing to carry out performance detection to microphone to be detected first with loudspeaker 120,
Then it is received by 170, meanwhile, received audio-frequency information is analyzed by intelligent terminals such as computers, and based on the analysis results
The sound that loudspeaker 120 issue is adjusted, for example, adjusting size, the frequency of sound etc. that loudspeaker 120 issue, and then obtains demand
Standard voice, so that convenient test the performance of microphone to be detected.
Meanwhile guarantor when in order to make voice transmission to two microphones to be detected issued using the loudspeaker 120 after 170 debugging
It holds unanimously, to preferably carry out the judgement of the performance of two microphones to be detected.In the present embodiment, 170 two are installed on
The midpoint of microphone to be detected.To make two microphones to be detected be equidistant with 170, so that the sending of loudspeaker 120
Sound transmission to two microphones to be detected when it is consistent.
Also, in the present embodiment, the circular in cross-section of loudspeaker 120, and the cross of the position of 170 installations and loudspeaker 120
The midpoint in section is opposite, on the one hand, is installed on the position opposite with 120 midpoint of loudspeaker for 170, loudspeaker 120 can be made to issue
Sound when sound transmission is to 170 damages minimum.On the other hand, the midpoint for being installed on two microphones to be detected due to 170, and
It is more accurate in order to detect, it needs for microphone to be detected to be placed in the face region of loudspeaker 120.Therefore, in being placed in when 170
, it can be achieved that the advantages of reducing 120 cavity volume of loudspeaker when point position.It further, can by reducing 120 cavity volume of loudspeaker
The resonance point for improving sound, makes 120 cavity curve of loudspeaker in calibration range, tests more stable.
The people are needed, in the present embodiment, the surrounding of loudspeaker 120 is provided with the first mounting hole 113, and in support plate
Be also equipped with second mounting hole corresponding with first mounting hole 113 on 110, i.e. the first mounting hole 113 and the second mounting hole
Position, size and quantity are all the same, pass through the first mounting hole 113 and the second mounting hole using screw, it can be achieved that support plate 110 and
Loudspeaker 120 are detachably connected.
Further, in order to adjust resonance frequency, in the present embodiment, microphone test device 100 further includes the first chamber
Body 130, the first cavity 130 are connect with support plate 110 with loudspeaker 120 respectively.By adjusting the size and length of the first cavity 130,
Adjustment microphone to be detected can be achieved and enter the size and depth of deep hole, so that resonance point be made to move back, reach and make test more stable
Effect.
In the present embodiment, in order to guarantee the effect tested, microphone test device 100 further includes the second cavity 140, the
One end of two cavitys 140 is provided with opening, and the second cavity 140 is sheathed on outside loudspeaker 120 and the second cavity 140 connects with support plate 110
It connects, so as to the cavity of sealing be formed between loudspeaker 120 and the second cavity 140, to seal entire test chamber.Pass through setting second
Cavity 140, the sound that loudspeaker 120 can be made to issue will not leak, to ensure that two microphones to be detected receive in test
The sound arrived is more stable.
Further, in practical applications, after microphone to be detected is placed in placement hole 111, if not to its into
Row is fixed, then may cause microphone sliding to be detected when detecting, influence test effect.Therefore, in order in Mike to be detected
Wind fixes the microphone to be detected when detecting, and in the present embodiment, microphone test device 100 further includes pressing plate 150, support plate
For installing loudspeaker 120, one side and the pressing plate 150 of the separate loudspeaker 120 of support plate 110 are detachably connected 110 one side.By setting
Pressing plate 150 is set, microphone to be detected can be limited after microphone to be detected is installed in placement hole 111, to prevent
Only in the detection process, the position of microphone to be detected is moved, and testing result is relatively reliable.
Specifically, in the present embodiment, the two sides positioned at loudspeaker 120 of support plate 110 are provided with location hole 112, pressing plate 150
It is provided with positioning pin 151, support plate 110 is connect by location hole 112 with positioning pin 151 with pressing plate 150.I.e. by Mike to be detected
After wind is installed on placement hole 111, the positioning pin 151 of pressing plate 150 and the location hole 112 of support plate 110 are pressed, to realize pressure
The connection of plate 150 and support plate 110, while position-limiting action is reached to microphone to be detected.
Further, in the detection process, it needs for microphone to be detected to connect with intelligent terminals such as computers, with realization pair
The analysis of audio-frequency information connects for convenience, is originally being in private, microphone detection device includes needle mould device 160, needle mould dress
It sets 160 and is installed on pressing plate 150, needle mould device 160 with microphone to be detected for connecting.It, can by the way that needle mould device 160 is arranged
Facilitate and be electrically connected intelligent terminal and device to be detected, to achieve the effect that detect microphone property.
