Description
Technical field
The present invention relates to loudspeaker sound channel detection technique field, specially a kind of loudspeaker left and right acoustic channels distinguish detection device and its
Detection method.
Background technology
During our listenings, sound can be told and transmitted by which direction, so as to substantially determine the position of sound source.
We are due to that we have the reason of two ears so the direction of sound can be differentiated.For example, there is one in our right front
Sound source, then, because auris dextra is nearer from sound source, sound just passes to auris dextra first, then just pass to left ear, and auris dextra is heard
Sound is more slightly more strong than the sound that left ear is heard.If the sound rate that sound source is sent is very high, be transmitted to left ear sound some can quilt
The number of people reflects back, thus left ear is just not easily heard this sound.Two ears to this minute differences of the sensation of sound,
Pass in cerebral nerve, just enable us to judge that sound is to come from right front., will here it is usually said " binaural effect "
It is this by two sound receiving terminals to sound preserve processing in a manner of with loudspeaker, then can reach the effect for preserving three-dimensional sound
Fruit.
When the left and right sound channels of loudspeaker break down, it is necessary to be overhauled, surveyed at present for many TV SKDs of producing line
When examination, loudspeaker divide L channel loudspeaker and R channel loudspeaker, during playing audio/video file, it is necessary to carefully listened with ear very much
It is whether normal that the loudspeaker left and right sound track signals of TV SKD can just be told, even need to be gone to touch loudspeaker with hand when necessary
Whether surface is shaken to judge, time-consuming and easy error, therefore, we have proposed a kind of loudspeaker left and right acoustic channels to distinguish detection device
And its detection method.
The content of the invention
It is an object of the invention to provide a kind of loudspeaker left and right acoustic channels to distinguish detection device and its detection method, with solution
When stating proposed in background technology current and tested for many TV SKDs of producing line, loudspeaker divide L channel loudspeaker and R channel
Loudspeaker, play audio/video file during, it is necessary to loudspeaker that can just tell TV SKD or so are carefully listened very much with ear
Whether sound channel signal is normal, even needs to be gone to touch whether flared surface is shaken to judge with hand when necessary, time-consuming and easy
The problem of error.
To achieve the above object, the present invention provides following technical scheme：A kind of loudspeaker left and right acoustic channels distinguish detection device, bag
Mounting seat is included, the bottom of the mounting seat is bonded with rubber antiskid pad by bonding agent, connected at the top of the mounting seat
Outer protecting shell is connected to, LED light is embedded with the top of the outer protecting shell, being respectively connected with transmission at left and right sides of the outer protecting shell leads
Line, transfer wire described in two groups are electrically connected with the two arrays of electrodes of LED light respectively, and the outer end of transfer wire is equal described in two groups
It is connected with conductive clip.
Preferably, the left and right sidewall of the outer protecting shell is embedded with rubber ring, and two groups of rubber rings are socketed in two groups of biographies respectively
On the outer wall of transporting line.
Preferably, the LED light is plugged on outer protecting shell, and the inner chamber of the outer protecting shell is provided with and LED light
The grafting copper pipe being adapted, transfer wire described in two groups is respectively with corresponding grafting copper pipe to being connected.
Preferably, it is coated with electro-insulating rubber skin at the outer wall handle of the conductive clip.
A kind of loudspeaker left and right acoustic channels distinguish the detection method of detection device, and the loudspeaker left and right acoustic channels distinguish the inspection of detection device
Survey method comprises the following steps that：
S1：Access the detection device：The place circuit of former loudspeaker is cut off, is gone here and there respectively on the horn wire of loudspeaker left and right acoustic channels
Join LED light, correct access LED light moved towards according to both positive and negative polarity, two groups are connected with two groups of joints of cut-off part respectively,
Then LED light is connected in series in the circuit of loudspeaker, mounting seat is placed on to obvious place, rubber antiskid pad is supported on platform
On face；
S2：Observation detection：During normal use, when left and right acoustic channels have signal output to loudspeaker, it is connected on horn wire
LED light bright can will be lighted under the driving of electric energy, if breaking down, the LED light on horn wire then will not point
It is bright；
S3：Breakdown judge：According to step S2 display result, tester just can directly judge electricity by vision can
Whether the left and right sound track signals depending on mainboard are working properly.
Compared with prior art, the beneficial effects of the invention are as follows：This programme use is on machining production line, machining production line
Acquisition testing result as fast as possible is needed, this programme solution is original to listen the loudspeaker that can just tell TV SKD with ear
The whether normal mode of left and right sound track signals, improve detection efficiency and accuracy rate.
