The driving member 240 includes a driving motor 242, a driving telescopic rod 244 and a sliding rod 246. The driving motor 242 is connected to the first housing 210. The output end of the driving motor 242 is connected to the driving telescopic rod 244. The driving motor 242 is further connected to the first button 110 and the second button 120, respectively, for driving the extension and retraction of the driving telescopic rod 244. Referring to fig. 2, the driving rod 244 is further connected to the sliding rod 246. The second housing 220 defines an arc-shaped sliding slot 222. The sliding rod 246 is slidably disposed in the arc-shaped sliding slot 222.
In this embodiment, the arc-shaped chute 222 is disposed on the second housing 220, so that the sliding rod 246 slides in the arc-shaped chute 222, and the sliding rod 246 moves on the second housing 220 along the extending direction parallel to the arc-shaped chute 222, that is, the sliding track of the sliding rod 246 on the second housing 220 is arc-shaped, and the output end of the driving motor 242 only controls the extension and retraction of the driving telescopic rod 244, so that the driving telescopic rod 244 performs telescopic movement without rotating, so that the driving motor 242 is a telescopic motor, and further the driving manner of the driving motor 242 is single, which simplifies the driving manner of the driving motor 242, and reduces the structural complexity of the driving motor 242, thereby reducing the maintenance difficulty of the driving motor 242, and further reducing the testing cost of the earphone testing device.
In one embodiment, referring to fig. 1 and fig. 2, the telescopic driving rod 244 includes a plurality of telescopic sub-rods 2442 connected in sequence, and each telescopic sub-rod 2442 is used for adjusting the distance between the driving motor 242 and the sliding rod 246. In this embodiment, the plurality of telescopic sub-rods 2442 connected in sequence provide a length-adjustable function, and the driving telescopic rod 244 adjusts the distance between the sliding rod 246 and the bracket of the driving motor 242 through the telescopic distance between the telescopic sub-rods 2442, so that the sliding rod 246 moves in the arc-shaped sliding groove 222 through the change of the position relationship between the sliding rod 246 and the driving motor 242, thereby driving the second housing 220 to be far away from or close to the first housing 210, and facilitating the opening and closing of the earphone accommodating space of the earphone testing device.

In one embodiment, the housing assembly further comprises a shielding layer through which the driving motor is connected with the first housing. In this embodiment, the earphone to be tested is placed in the earphone accommodating space, wherein the earphone testing device is used for carrying out acoustic testing on the earphone, and isolation and shielding are needed to be carried out on external sound signals. Because the external interference sound source of the earphone testing device mainly comes from the driving motor, when the earphone performance test is carried out, the shielding layer isolates the sound emitted by the driving motor outside the earphone accommodating space, the probability of external interference sound waves entering the earphone accommodating space is reduced, and the accuracy of the test result of the earphone testing device is improved.
In one embodiment, the housing assembly further comprises a heat dissipation layer, the heat dissipation layer is connected with the first housing and the second housing, and a surface of the heat dissipation layer facing away from the first housing is further connected with the driving motor. In this embodiment, since the driving motor is a main power unit, and is connected to an external power supply, the external power supply provides electric energy for the operation of the driving motor and the testing component in the testing device for the earphones, and when the driving motor operates, heat generated by the telescopic work of the driving motor is conducted to the first housing and the second housing, so that the temperature of the first housing and the second housing is increased, and the temperature in the accommodating space for the earphones is increased, which may cause deviation in performance testing of the earphones. In order to further improve the accuracy of the testing result of the earphone, heat dissipation layers are arranged on the surfaces of the first shell and the second shell, so that heat generated by the driving motor is dissipated through the heat dissipation layers. Under the structure of the large area of the heat dissipation layer, namely the heat dissipation area of the heat dissipation layer is large, the contact area between the heat dissipation layer and the air is increased, so that the heat exchange rate of the heat dissipation layer and the air is increased, the heat dissipation effect of the driving motor is improved, the probability of overhigh temperature in the earphone accommodating space is reduced, and the accuracy of the earphone test result is further improved. In other embodiments, the heat dissipation layer is provided with heat dissipation holes, and the heat dissipation area of the heat dissipation layer is further increased by providing the heat dissipation holes on the heat dissipation layer, so that the heat dissipation effect of the heat dissipation layer is improved.

In this embodiment, the first positioning pin 248 is used to position the slide bar 246 on the second housing 220, i.e., the first positioning pin 248 positions the slide bar 246 in the arc chute 222. When the slide bar 246 slides in the arc-shaped sliding groove 222, the first positioning pin 248 is not connected with the second housing 220, and when the slide bar 246 moves to a designated position of the arc-shaped sliding groove 222, the first positioning pin 248 is further extended into the first positioning hole 2462, so that the first positioning pin 248 is connected with the bottom of the arc-shaped sliding groove 222, that is, the first positioning pin 248 is connected with the second housing 220, so that the slide bar 246 is fixed at the designated position, and the positioning of the slide bar 246 is realized.
Further, referring to fig. 2, the second housing 220 is provided with a plurality of positioning slots 224 communicated with the arc-shaped sliding slot 222, the plurality of positioning slots 224 are uniformly distributed in the arc-shaped sliding slot 222, and the first positioning pin 248 is respectively inserted into the first positioning hole 2462 and one of the positioning slots 224. To facilitate positioning of the slide bar 246 at different positions, a plurality of positioning slots 224 are in communication with the arc-shaped sliding slot 222, and when the slide bar 246 moves to one of the positioning slots 224, the first positioning pin 248 passes through the first positioning hole 2462 and protrudes into the positioning slot 224, such that the end of the first positioning pin 248 is received in the positioning slot 224. In this way, the first positioning pin 248 is inserted into the first positioning hole 2462 and the positioning slot 224, so as to improve the stability of the sliding rod 246 in the arc-shaped sliding slot 222.
Furthermore, referring to fig. 2, the driving member 240 further includes a second positioning pin 241, the sliding rod 246 further has a second positioning hole 2464, and the second positioning pin 241 is inserted into the second positioning hole 2464 and connected to the first positioning pin 248. In this embodiment, the second positioning hole 2464 is opened on the sliding rod 246, the sliding rod 246 slides in the arc-shaped sliding groove 222, and after the position of the sliding rod 246 is fixed, in order to improve the connection stability between the sliding rod 246 and the first positioning pin 248, the second positioning pin 241 is inserted into the second positioning hole 2464, so that the connection between the sliding rod 246 and the first positioning pin 248 is more stable, the swing amplitude between the sliding rod 246 and the first positioning pin 248 is reduced, and the connection stability between the sliding rod 246 and the first positioning pin 248 is improved.
It can be understood that, the first casing 210 and the second casing 220 of the testing device for earphones are rotatably connected with each other, an earphone accommodating space is formed between the first casing 210 and the second casing 220, and the earphone accommodating space is used for placing a testing device for testing various performances of earphones, so that the testing of various performances of earphones is facilitated. Wherein the driving member 240 rotates the second housing 220 relative to the first housing 210 by moving itself, so as to close or open the earphone accommodating space by rotating the second housing 220, and the control of said actuating member 240, by means of two buttons provided on the base 100, namely, the first button 110 and the second button 120, wherein the first button 110 is a close button that controls the first housing 210 and the second housing 220 to be closed, the second button 120 is an open button for controlling the opening of the first housing 210 and the second housing 220, the close button and the open button are both disposed on the base 100, and both the close button and the open button are connected to the driving member 240, for driving the driving member 240 to move the second housing 220 toward or away from the first housing 210. However, in an actual testing process, the body of the operator may easily touch the close button or the open button by mistake, for example, when the earphone is placed in the earphone accommodating space, the body of the tester needs to be tilted forward, and at this time, the tester easily touches the close button, and starts the driving member 240, so that the second housing 220 starts to be closed, that is, the second housing 220 rotates toward the first housing 210, if the arm is not timely pulled out from the earphone accommodating space, the arm is easily pinched by the second housing 220, and the life safety of the operator is threatened; for another example, in the process of performing an earphone test, the second housing 220 and the first housing 210 are in a closed state, and at this time, an operator easily touches the opening button by mistake, so that the second housing 220 starts to open, that is, the second housing 220 rotates in a direction away from the first housing 210, and for the self-safety protection reason of the machine, the earphone test apparatus will automatically interrupt the test, so that the earphone test is forcibly interrupted, the test time of the earphone is increased, and the efficiency of the earphone test is reduced.
In order to reduce the possibility of the second housing 220 rotating incorrectly, referring to fig. 1 and 3 together, the testing device 10 further includes a button protection assembly 400, wherein the button protection assembly 400 includes a first protection member 410, a second protection member 420 and a pressing member 430; the first protection member 410 includes a first slider 412, a first elastic rod 414, and a first baffle 416, the second protection member 420 includes a second slider 422, a second elastic rod 424, and a second baffle 426, the first slider 412 is disposed opposite to the second slider 422, the first slider 412 has a first sliding inclined surface 4122, the first sliding inclined surface 4122 is disposed obliquely toward the second slider 422, the second slider 422 has a second sliding inclined surface 4222, the second sliding inclined surface 4222 is disposed obliquely toward the first slider 412, the first slider 412 and the second slider 422 are both slidably disposed on the base 100, the first baffle 416 is connected to a side of the first slider 412 away from the second slider 422 through the first elastic rod 414, the first slider 412 has a first through hole 4124, the first button 110 is disposed in the first through hole 4124, the second baffle 426 is connected with one side of the second sliding block 422, which is away from the first sliding block 412, through the second elastic rod 424, the second sliding block 422 is provided with a second through hole 4224, the second button 120 corresponds to the second through hole 4224, and the second button 120 is located between the second sliding block 422 and the second baffle 426; the pressing member 430 includes a first connecting rod 432, a second connecting rod 434, and a pressing plate 436, the first connecting rod 432 is connected to the second housing 220, the first connecting rod 432 is further connected to the pressing plate 436 through the second connecting rod 434, the pressing plate 436 has a first pressing inclined surface 4362 and a second pressing inclined surface 4364, the first pressing inclined surface 4362 is used to press the first sliding inclined surface 4122, and the second pressing inclined surface 4364 is used to press the second sliding inclined surface 4222. In this embodiment, the pressing member 430 moves following the second housing 220, that is, when the driving member 240 is opened, the pressing member 430 moves together with the second housing 220. For example, when the second housing 220 rotates towards the first housing 210, the pressing member 430 moves towards the first slider 412 and the second slider 422, when the pressing plate 436 presses the first slider 412 and the second slider 422, the first pressing inclined surface 4362 abuts against the first sliding inclined surface 4122, the second pressing inclined surface 4364 abuts against the second sliding inclined surface 4222, under the combined connection of the first elastic rod 414 and the first baffle 416, and the combined connection of the second elastic rod 424 and the second baffle 426, the lengths of the first elastic rod 414 and the second elastic rod 424 gradually decrease, that is, the first elastic rod 414 and the second elastic rod 424 gradually contract, so that the first slider 412 and the second slider 422 move away from the pressing plate 436, and the first slider 412 moves away from the first button 110, the second slider 422 is close to the second button 120, so that the first button 110 leaves the first through hole 4124 and is located outside the first slider 412, and the second button 120 enters the second through hole 4224 and is located inside the second slider 422. In this way, when the second housing 220 and the first housing 210 are closed, that is, the earphone testing device performs the earphone performance test, the second button 120 is protected by the second slider 422, so that the probability that the operator touches the second button 120 by mistake is reduced, and the probability that the test is interrupted when the earphone testing device performs the test because the second housing 220 is opened is reduced. Furthermore, after the testing of the earphone testing device is finished, the operator can press the second button 120 by inserting a finger or an operation into the second through hole 4224, so that the earphone testing device is opened, i.e. the driving member 240 drives the second housing 220 to rotate in a direction away from the first housing 210. In this embodiment, a projection of the first pressing inclined plane 4362 on the base 100 is offset from a projection of the close button and a projection of the open button on the base 100, that is, there is no overlapping area between the projection of the first pressing inclined plane 4362 on the base 100 and the projection of the close button on the base 100, and there is no overlapping area between the projection of the first pressing inclined plane 4362 on the base 100 and the projection of the open button on the base 100.
