Description

Technical Field

[0001] This invention relates to the field of headphone manufacturing equipment, and more particularly to a 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 CN201922179578.9 discloses an acoustic testing device for Bluetooth headsets, including a base. An adjustment plate is installed at the center of the upper surface of the base. Two adjustment rods are symmetrically installed on the upper surface of the adjustment plate, and a simulated mouth is installed inside the two adjustment rods. Symmetrical support rods are installed on the upper surface of the base, and a placement platform is installed inside the two support rods, positioned directly in front of the simulated mouth. The Bluetooth headset is fixed to the base, and acoustic testing is performed by directly facing the headset's microphone through the simulated mouth. However, this type of device, by testing directly facing the headset, cannot effectively test the microphone's unidirectional sound pickup function, meaning it can only pick up sound from one direction, thus avoiding ambient noise interference. Furthermore, the distance between the simulated mouth and the headset cannot be adjusted, making it inconvenient to perform acoustic testing on the headset from 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 an earphone testing device.

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

[0007] This invention discloses a headphone testing device, comprising a base plate, a turntable on the base plate, a simulated mouth fixed on the turntable, and the turntable driven to rotate by a rotary motor. A sliding rod and a lead screw are also disposed above the base plate, the lead screw being driven to rotate by a positioning motor. A sliding plate is also disposed above the base plate, the lead screw passing through the sliding plate and threadedly connected to it, and the sliding rod passing through the sliding plate and slidably connected to it. A fixing seat is fixed on the sliding plate, and the fixing seat has multiple positioning holes. During Bluetooth headphone testing, the bottom of the Bluetooth headphone is inserted into the positioning holes, sound is emitted through the simulated mouth, and the corresponding audio is received by the headphone. The rotary motor drives the turntable to rotate, adjusting the direction of the simulated mouth. The direction and angle of the sound received by the Bluetooth headphone are then confirmed by the audio received by the headphone, verifying the unidirectional pickup function of the microphone in the headphone. Furthermore, the positioning motor drives the lead screw to rotate, adjusting the position of the sliding plate, thereby adjusting the position of the Bluetooth headphone and thus the distance between the simulated mouth and the Bluetooth headphone. This allows for the detection of audio signals received by the Bluetooth headphone and the simulated mouth at different positions, confirming the functionality of the Bluetooth headphone.

[0008] Preferably, limit blocks are symmetrically fixed on both sides of the fixing base, and a limit rod rotatably connected to the limit blocks is provided between the two limit blocks. Multiple limit plates are fixed on the limit rod, and limit magnets are fixed on each limit plate. Positioning magnets are fixed on the fixing base at positions corresponding to the limit magnets. After the earphone is fixed, rotating the limit rod causes the limit magnets on the limit plates to attract each other with the positioning magnets on the fixing base, thus fixing the limit plates. The limit plates cover the earphones, securing the Bluetooth earphones and preventing them from vibrating and falling off the fixing base during testing.

[0009] Compared with existing technologies, the present invention has the following advantages:

[0010] By adjusting the direction of the simulated mouth, the unidirectional pickup function of the microphone in the headset can be confirmed. Furthermore, by adjusting the position of the Bluetooth headset and detecting the audio signals received by the Bluetooth headset and the simulated mouth at different positions, the functionality of the Bluetooth headset can be confirmed.

During Bluetooth headset testing, the bottom of the Bluetooth headset is inserted into the positioning hole 10. Sound is emitted through the simulated mouth 3, and the corresponding audio is received by the headset. The rotating motor 4 drives the turntable 2 to rotate, adjusting the direction of the simulated mouth 3. Then, the direction and angle of the sound received by the Bluetooth headset are confirmed by the audio received by the Bluetooth headset, confirming the unidirectional pickup function of the microphone in the headset. The positioning motor 7 drives the lead screw 6 to rotate, adjusting the position of the slide plate 8, thereby adjusting the position of the Bluetooth headset. This adjusts the distance between the simulated mouth 3 and the Bluetooth headset, thereby detecting the audio signals received by the Bluetooth headset and the simulated mouth 3 at different positions, confirming the function of the Bluetooth headset.
