Description

Technical Field

[0001] The utility model relates to the technical field of acoustics, in particular to a positioning device for testing a headphone. Background Art

[0002] Headphones are a pair of conversion units that receive electrical signals from a media player or receiver and convert them into audible sound waves using sound-producing units placed close to the ears. Headphones can prevent distractions to others and block out ambient noise, preventing them from affecting the user. Traditional headphones are commonly used with products such as mobile phones, walkmans, portable video games, and digital audio players, connecting to these devices via wires. However, with the rapid advancement of technology in recent years, wireless headphones that transmit audio signals wirelessly have become increasingly popular. To ensure quality during the production process, headphones must be tested after they are completed. Acoustic testing of headphones requires the headphones to be placed inside a shielded test chamber. Currently, testing of wireless headphones typically involves setting up two artificial ears for testing, and workers inserting and removing the headphones. However, this method requires workers to pull the left and right sound-producing units apart to insert or remove the headphones. This not only reduces testing efficiency but also increases labor intensity. Over time, fatigue can easily cause the headphones to shift position, impacting the test. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to facilitate those skilled in the art to understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and drawings.

[0024] Reference Figures 1 to 4 The present invention provides a positioning device for testing headphones, comprising a base, a linear drive mechanism disposed on the base, a first test machine assembly and a second test assembly disposed on the linear drive mechanism, a first pressing mechanism disposed on the base for pressing the headphones against the first test assembly, and a second pressing mechanism disposed on the base for pressing the headphones against the second test assembly. The first test assembly and the second test assembly respectively correspond to the two sound-emitting units of the headphones, and the first pressing mechanism and the second pressing mechanism also function similarly. After the two sound-emitting units of the headphones are placed on the first test assembly and the second test assembly, the first pressing mechanism and the second pressing mechanism can respectively press the two sound-emitting units.

[0025] The first test assembly and the second test assembly both include an artificial ear connected to the linear drive mechanism and a support seat arranged above the artificial ear. The support seat is provided with a through hole at a position corresponding to the artificial ear to facilitate the artificial ear to collect sound.

[0026] The first and second clamping mechanisms each include a clamping seat, a first clamping cylinder mounted on the clamping seat, and a first clamping member connected to the output end of the first clamping cylinder. The first clamping cylinder is a rotating downward-pressing cylinder, allowing the first clamping member to move away from above the first or second test assembly, thereby facilitating easy removal of the earphones.

[0027] The pressing seat is provided with a buffer matched with the pressing cylinder. The buffer matches the first pressing member. When the first pressing cylinder drives the pressing member to press down, the buffer and the pressing member contact to prevent the earphone from being damaged by excessive impact force.

[0028] The base is provided with a recessed platform at a position corresponding to the compression seat, and the recessed platform is provided with a first waist-shaped hole along the driving direction of the linear drive mechanism. The first waist-shaped hole is elongated, and the compression seat can be adjusted along the first waist-shaped hole. After being adjusted to the appropriate position, it is tightened with fasteners such as bolts, allowing for flexible adjustment for different models of headphones. The first and second compression mechanisms can ensure the compression effect of different models of headphones, making them more versatile.

[0029] The linear drive mechanism is provided with several bearing components for supporting the headphone headband, and the bearing components include a bearing frame connected to the linear drive mechanism and a bearing member provided on the bearing frame. The bearing member is provided with a supporting groove that matches the headphone headband, and the shape of the supporting groove matches the headphone headband. In this embodiment, there are three bearing components, corresponding to the middle of the headband and the two ends of the headband, respectively, supporting the headphone headband at three points to ensure the stability of the headphones and avoid displacement during the test.

[0030] The support frame includes a bottom plate and a vertical plate arranged on the bottom plate, the bottom plate is provided with a second waist-shaped hole, the vertical plate is provided with a third waist-shaped hole, and the support member is connected to the vertical plate. The second waist-shaped hole is arranged in the horizontal direction, and the support frame can adjust its position along the second waist-shaped hole. Taking the accompanying drawings of this embodiment as an example, the driving direction of the linear drive mechanism is defined as the Y-axis, wherein two support components can be adjusted along the X-axis, and the other support component can be adjusted along the Y-axis, so that the positions of the three support components can be adjusted according to the specifications of the earphones (i.e., the size of the headband), and it can be flexibly adapted to the testing of earphones of different specifications. In addition, the movable plate in this embodiment is provided with a connecting groove for connecting to the support frame, and the bottom plate of the support frame can be adjusted along the connecting groove.

[0031] The linear drive mechanism includes a linear drive member arranged on the base, a movable plate connected to the linear drive member, and the first test assembly and the second test assembly are both arranged on the movable plate. The positioning device for testing headphones provided by the present invention needs to be fixed inside the shielding wire of the acoustic test instrument when in use. Under the action of the linear drive member, the movable plate can move a certain distance toward the outside, thereby facilitating the insertion or removal of headphones. In this embodiment, the linear drive member adopts a slide cylinder. Of course, other types of linear drives, such as an electric lead screw, may also be used in specific implementation.

[0032] The base is provided with a third pressing mechanism for pressing the headphone headband, and the third pressing mechanism includes a second pressing cylinder connected to the linear drive mechanism and a pressing member connected to the second pressing cylinder.

[0033] When conducting a headphone test, the shielding box of the test equipment is in an open state, and the movable plate is driven by the driving member to move a certain distance outward. At this time, the headphones can be placed by the manipulator, and the two sound units of the headphones are placed on the supporting seat of the first test component and the supporting seat of the second test component respectively, and the headband part enters the supporting slot. After that, the movable plate is reset, and the first clamping mechanism, the second clamping mechanism, and the third clamping mechanism clamp the headphones. The shielding box automatically closes, and then the test equipment performs an acoustic test on the headphones. After the test is completed, the shielding box is opened, the first clamping mechanism, the second clamping mechanism, and the third clamping mechanism are reset, and the movable plate moves outward again. At this time, the manipulator can take away the headphones that have completed the test, completing a test process, and then new headphones to be tested can be put in again, and so on.

[0034] The present invention is provided with a first test assembly and a second test assembly. With the cooperation of the first and second clamping mechanisms, the two sound-emitting units of the headphones are placed flat on the first and second clamping mechanisms to achieve the clamping and positioning of the headphones. No manual operation is required, and the positioning is fast and accurate, thereby improving the testing efficiency. At the same time, with the cooperation of the linear drive mechanism, the first and second test assemblies can be moved, facilitating the removal and placement of the headphones. On the other hand, the present invention is also provided with a bearing assembly and a third clamping mechanism to clamp and fix the headband of the headphones, further ensuring the stability of the headphones during the test process and preventing displacement that affects the accuracy of the test results.
