Description

Technical Field

[0001] This invention relates to the field of headphone manufacturing equipment, and more particularly to a Bluetooth headphone testing device. Background Technology

[0002] After headphones are manufactured and assembled, they typically undergo various functional tests before being packaged and shipped to prevent defective products from entering the market. Acoustic testing is an indispensable part of the headphone speaker function testing, which includes testing the earpiece and microphone.

[0003] Patent application number CN202122220096.0 discloses an acoustic testing fixture for irregularly shaped headphones, including a base; a positioning component disposed on the base for positioning the headphones; and a sound-generating component disposed on the base. The sound-generating component includes a fixing seat disposed on the base, a sound-generating bracket disposed on the fixing seat, and an artificial mouth disposed on the sound-generating bracket, with the artificial mouth facing the positioning component. After the headphones are fixed, they are tested using the simulated mouth. However, the distance between the simulated mouth and the headphones in this type of device cannot be adjusted, making it inconvenient to perform acoustic tests on the headphones at different positions.

[0004] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a Bluetooth headset testing device.

[0006] This invention can be achieved through the following technical solutions:

[0007] This invention discloses a Bluetooth headset testing device, comprising a platform, on which a sliding rod and a lead screw are disposed. The lead screw is driven to rotate by a positioning motor. A sliding plate threadedly connected to the lead screw is disposed on the lead screw, and the sliding rod passes through and slidably connects to the sliding plate. A simulated mouth is also fixed on the sliding plate. A turntable is also disposed on the platform, driven to rotate by a rotary motor. Multiple fixing devices are evenly fixed on the turntable. Each fixing device includes a fixing plate fixed on the turntable, and a fixing seat is fixed to the top of the fixing plate. The fixing seat has fixing holes. The device includes a push plate with a push rod fixed to its bottom. The push rod passes through a fixed seat and is slidably connected to it. A positioning block is fixed to the push rod below the fixed seat, and a spring is fixed between the positioning block and the fixed seat. A support shaft is fixed above a turntable on one side of the fixed seat, and a support plate is rotatably connected to the support shaft. Support rods are fixed at both ends of the push rod, and a sliding groove is provided at the end of the support plate to slidably connect with the support rod. A top plate is fixed above the table, and a cylinder is fixed to the top plate. A positioning plate is fixed to the end of the piston rod of the cylinder. The Bluetooth earphones to be tested are fixed by inserting their bottoms into the mounting holes of the mounting base. Audio is played through the simulated mouth, and the Bluetooth earphones' microphones receive the audio. A rotating motor drives a turntable to rotate, with each earphone passing in front of the simulated mouth in turn. The audio signals received by each earphone confirm that it can accurately receive the corresponding audio signal within a certain range in front of the simulated mouth, thus testing the unidirectional pickup function of the earphone microphones. A positioning motor drives a lead screw to rotate. Since the lead screw is threadedly connected to a sliding plate, the sliding plate moves in the direction of the lead screw as the lead screw rotates. Adjusting the distance between the simulated mouth and the earphone directly opposite the simulated mouth allows for confirmation of the earphone's pickup function. To check if the sound pickup distance meets the requirements, after the headphone test is completed, the headphone reaches the designated position, the cylinder starts, the piston rod of the cylinder extends, the positioning plate descends, the positioning plate pushes the support plate to rotate around the support shaft, one end of the support plate pushes the support rod to rise, the push plate rises, and the push plate pushes the tested headphone out of the fixing hole. The cylinder starts again, the piston rod of the cylinder shortens, the spring pushes the positioning block to descend, the push plate returns to the bottom of the fixing hole, and the headphone to be tested is placed on the fixing seat again. This device can perform acoustic tests on multiple headphones at the same time, and the unidirectional sound pickup function of the microphone can be tested by adjusting the angle between the simulated mouth and the headphone, and the sound pickup function of the headphone can be tested by adjusting the distance between the headphone and the simulated mouth.

[0008] Preferably, the turntable surrounds the simulated mouth, a circular rack is fixed to the bottom of the turntable, and a gear is fixed to the output end of the rotary motor, the gear meshing with the circular rack.

[0009] Preferably, a positioning rod is fixed below the positioning plate, and a roller is provided on the positioning rod. The roller contacts the support plate, causing the support plate to rotate.

[0010] Compared with existing technologies, the present invention has the following advantages:

[0011] This device can perform acoustic tests on multiple headphones at once, and can test the unidirectional pickup function of the microphone by adjusting the angle between the simulated mouth and the headphones, and can test the headphone pickup function by adjusting the distance between the headphones and the simulated mouth.
