Description

Technical Field

[0001] This utility model relates to the field of headphone testing technology, specifically to a headphone acoustic performance testing fixture with a surround rotation function. Background Technology

[0002] Wireless headphones are a common digital product that helps people enjoy music and audio-visual products, and are a widely used digital device.

[0003] During the manufacturing process of wireless headphones, acoustic performance testing is required. This testing involves vibrating the headphones with an acoustic device to detect vibrations. By analyzing the vibration parameters and the parameters detected by the built-in sound sensor, the device's ability to receive sounds from different directions and frequencies can be determined, thus assessing the headphone's quality. Typically, the headphones are fixed on a testing platform, and sound is detected through speakers in two directions. By measuring the vibration frequencies in both directions, the device's parameters can be adjusted. This process also allows for the timely detection and handling of any defective products produced during manufacturing.

[0004] In the acoustic testing process of wireless headphones, existing methods can only test a single headphone in two directions. However, there are many different audio frequencies in headphones during use, and testing in two directions is not accurate enough for the test results. Moreover, testing a single headphone is inefficient for the overall testing process. Therefore, existing acoustic testing methods for wireless headphones suffer from low efficiency and inaccurate test results. Utility Model Content

[0005] The purpose of this invention is to simultaneously distinguish and detect the left and right channels of multiple sets of headphones by setting up a ring-shaped speaker and multiple angle detection modules, thereby improving the accuracy and efficiency of detection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a headphone acoustic performance testing fixture with a circumferential rotation function, comprising a testing base plate, a testing linear module disposed on the testing base plate, a testing component slidably connected to the testing linear module, the testing component comprising a testing placement plate and headphone placement slots arrayed on the testing placement plate, the headphone placement slots being filled with an elastic compression sleeve, and a ring-shaped moving audio component disposed around the testing placement plate, the opening of the audio component always facing the testing placement plate, the testing component further comprising a testing base, the testing placement plate being rotatably connected to the testing base.

[0007] Preferably, a detection frame is fixedly connected to the detection base, a detection shaft is rotatably connected to the detection frame, and a rotary motor is fixedly connected to one side of the detection shaft.

[0008] Preferably, a movable slide is fixedly connected to the detection base plate, a movable groove is provided on the movable slide, and a slide rail is fixedly connected to the bottom of the detection base, the slide rail being slidably connected within the movable groove.

[0009] Preferably, the detection base plate has an annular slide rail, and a speaker base is slidably connected in the annular slide rail. The speaker assembly includes a speaker support plate and a vertical speaker fixedly connected to the surface of the speaker support plate. The speaker support plate is fixedly connected to the speaker base.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. The detection component is set up so that it can slide in a straight line and flip, and can place multiple sets of left and right channel headphones at the same time. This allows for sound detection from multiple angles and simultaneous detection of multiple sets of headphones, which greatly improves detection efficiency and accuracy.

[0012] 2. A ring-shaped audio component is set up, which can move in a ring to generate sound vibration. Audio vibration can be detected at any position within the circumference area, further improving the accuracy of the detection results. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0021] refer to Figure 1-3 A detection base plate 1 is set up, and acoustic testing is performed on the detection base plate 1. This allows the headphones to be monitored by emitting sound to the headphones from different directions. After the test is completed, the vibration frequency of the headphones can be used to determine whether the headphones are qualified and their response to different frame rates of sound quality from different directions.

[0022] refer to Figure 1-3 A detection linear module 11 is provided on the detection base plate 1. The detection linear module 11 has a lead screw structure inside, which can drive two parts to move along opposite threads at one end, thereby achieving the effect of synchronous bidirectional movement. A detection component 2 is slidably connected to the detection linear module 11. The detection component 2 is symmetrically arranged, which can place the left channel earphone on one side and the right channel earphone on the other side. A detection connecting plate 16 is slidably connected to the detection linear module 11. The detection connecting plate 16 can be driven to slide by the detection linear module 11. The detection component 2 includes a detection placement plate 21 and earphone placement slots arrayed on the detection placement plate 21. The earphone placement slots are filled with elastic compression sleeves. The elastic compression sleeves are rubber sleeves. When the end of the earphone is inserted into the earphone placement slot, it will compress the earphone through elastic deformation. The detection assembly 2 also includes a detection base 23, a detection placement plate 21 rotatably connected to the detection base 23, a detection frame 231 fixedly connected to the detection base 23, a detection shaft 232 rotatably connected to the detection frame 231, a rotary motor 233 fixedly connected to one side of the detection shaft 232, the rotary motor 233 drives the detection shaft 232 to rotate, and drives the detection placement plate 21 to tilt, thereby adjusting the detection angle when the headphones are placed, and thus detecting the vibration frequency of the headphones at different angles. The detection connection plate 16 is fixedly connected to the detection base 23, realizing the effect of synchronously driving the detection assembly 2 to move by the detection linear module 11, and realizing the effect of adjusting the distance and relative angle between the left channel headphones and the right channel headphones.

[0023] refer to Figure 1-3A movable slide rail 12 is fixedly connected to the detection base plate 1. A movable slide groove 13 is provided on the movable slide rail 12. A slide rail 14 is fixedly connected to the bottom of the connecting plate of the detection base 23. The slide rail 14 is slidably connected in the movable slide groove 13. When the detection connecting plate 16 moves relative to the detection linear module 11, the detection frame 231 moves. The slide rail 14 at the bottom of the detection connecting plate 16 slides in the movable slide groove 13, so that it can only move along the length direction of the movable slide groove 13, thus limiting the movement direction.

[0024] refer to Figure 1-3 The detection placement plate 21 is surrounded by a ring-shaped moving speaker assembly 3. The opening of the speaker assembly 3 always faces the detection placement plate 21. The detection base plate 1 has an annular slide rail 15. The speaker base 31 is slidably connected in the annular slide rail 15. The speaker assembly 3 includes a speaker support plate 32 and a vertical speaker 33 fixedly connected to the surface of the speaker support plate 32. The speaker support plate 32 is fixedly connected to the speaker base 31. The opening orientation of the vertical speaker 33 can be adjusted by rotating the position of the speaker base 31, thereby detecting the sound vibration of several headphones on the detection assembly 2 from different directions and improving the accuracy of the detection.

[0025] The working principle of this device is as follows: When conducting acoustic testing on headphones, several pairs of headphones are inserted into the headphone placement slots on two headphone placement plates, one for the left and one for the right channels. They are then elastically fixed by the elastic compression sleeves in the headphone placement slots. At this time, the two speaker components 3 are rotated to the position to be tested, and the speakers are turned on. After obtaining the readings, the linear detection module 11 and the rotary motor 233 are started. The positions and placement angles of several headphones on the left and right channels are adjusted, and the vertical speakers 33 are turned on again to obtain the test readings. Then, the positions of the speaker components 3 are adjusted again to ensure that the two speaker components 3 are always on the same straight line for testing. After three tests, the readings are obtained, and the acoustic performance readings of several pairs of headphones can be analyzed, thus completing the acoustic performance testing process for several headphones.

[0026] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
