[0002] After the earphones are manufactured and assembled, they are usually tested for various functions before being packaged and shipped to prevent defective products from entering the market. The earphone acoustic test is an indispensable part of the earphone speaker function. This includes testing the earpiece and microphone.

[0003] Patent application number: CN202321802751.6 discloses a bone conduction headphone acoustic test fixture, including a base and an artificial mouth, the artificial mouth is arranged above the base, characterized in that a support frame is arranged on the base, a support is fixed on the support frame near the artificial mouth, a positioning fixture is installed on the top of the support, the headphone can be placed on the positioning fixture, a telescopic member is arranged on the base at the support frame, the telescopic end of the telescopic member is fixedly connected to a connecting frame, at least two conductive members are fixed on the connecting frame, and both conductive members can press and clamp the headphone. After the headphone is fixed, the headphone is tested through the artificial mouth, but this type of device is tested by facing the headphone directly, and the one-way pickup function of the microphone cannot be well tested, that is, it can only pick up sound in one direction to avoid environmental sound interference, and the distance between the artificial mouth and the headphone cannot be adjusted, which is inconvenient for acoustic testing of the headphone in different positions.

[0005] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a Bluetooth headset acoustic testing device.

[0006] The present invention can be implemented by the following technical solutions:

[0007] The present invention discloses a Bluetooth headset acoustic testing device, comprising a base plate, a turntable rotatably connected to the base plate is arranged on the base plate, the turntable is driven to rotate by a limit motor, a positioning plate rotatably connected to the turntable is arranged on the turntable, an arc-shaped rack is fixed on the positioning plate, a positioning motor is fixed on the turntable, a positioning gear is fixed on the output end of the positioning motor, the positioning gear is meshed with the arc-shaped rack, a plurality of arc-shaped positioning grooves penetrating the positioning plate are also evenly arranged on the positioning plate, the turntable at the position of the positioning groove is provided with a limit groove, the limit groove is provided with a slider slidably connected to the limit groove, a positioning shaft is fixed on the bottom of the slider, the positioning shaft is slidably connected to the positioning groove at the corresponding position, a fixing seat is fixed on the slider, a mounting hole is arranged on the fixing seat, and a simulation mouth is also fixed on the base plate in the middle of the turntable. Insert the bottom of the Bluetooth headset to be tested into the mounting hole of the fixing seat to fix the headset, play audio through the artificial mouth, receive audio through the microphone of the Bluetooth headset, and drive the turntable to rotate through the limit motor, and each headset passes in front of the artificial mouth in turn. The audio signal received by the headset can confirm that each headset can accurately receive the corresponding audio signal within a certain range in front of the artificial mouth, that is, the test of the one-way sound pickup function of the headset microphone is realized, and the positioning gear is driven to rotate by the positioning motor, and the positioning gear is meshed with the arc rack. When the positioning gear rotates, the positioning plate rotates. Since the slider is slidably connected with the limit groove, the positioning shaft fixed on the slider is slidably connected with the positioning groove. When the positioning plate rotates, the slider moves in the limit groove, thereby adjusting the distance between each headset and the artificial mouth. When the distance between the headset and the artificial mouth is gradually adjusted, it can be confirmed whether the distance of the headset picking up sound meets the requirements. The device can perform acoustic tests on multiple headsets at one time, and the one-way sound pickup function of the microphone can be tested by adjusting the angle between the artificial mouth and the headset, and the sound pickup function of the headset can be tested by adjusting the distance between the headset and the artificial mouth.

[0008] Preferably, a circular rack is fixed on the turntable, a limiting gear is fixed on the output end of the limiting motor, and the limiting gear is meshed with the circular rack.

[0009] Preferably, slide bars are fixed on the turntables on both sides of the limiting groove, and the slide bars pass through the sliders at the corresponding positions and are slidably connected with the sliders. The support of the sliders is achieved by the slide bars passing through the sliders.

[0010] Preferably, the fixing seat is provided with a fixing block, and the fixing block is provided with a positioning hole penetrating the fixing block at a position corresponding to the mounting hole, and a plurality of fixing rods are fixed on the fixing seat, and the fixing block is provided with a fixing hole used in conjunction with the fixing rod. The bottom of the earphone is inserted into the positioning hole, and the fixing block is placed on the fixing seat, so that the earphone can be quickly fixed on the fixing seat, and the fixing block can be easily removed and replaced, further improving the testing efficiency of the earphone.

[0011] Preferably, the positioning shaft is also provided with a positioning wheel used in conjunction with the positioning groove.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] The device can perform acoustic tests on multiple headphones at one time, and can test the one-way sound pickup function of the microphone by adjusting the angle between the artificial mouth and the headphones, and can test the sound pickup function of the headphones by adjusting the distance between the headphones and the artificial mouth.
