However, there are certain errors in manually adjusting the height and horizontal distance, and this error will make the test results inaccurate. Summary of the Utility Model

[0034] The technical solutions of this application will be further described below in conjunction with embodiments and the accompanying drawings.

[0035] An embodiment of this application provides an audio test device. As Figure 1 and Figure 2 shown, the audio test device 100 includes a base 2, a first bracket 3, a second bracket 4, and a driving component (not marked in the figure). The base 2 can be set to a structure similar to a cuboid, with rounded corners at the four sides. The first bracket 3 is arranged at one end of the base 2. The cross-section of the first bracket 3 can be cylindrical or cuboid, and can be selected according to needs. The top of the first bracket 3 is used to carry the audio test equipment. The second bracket 4 is arranged at the other end of the base 2. The cross-section of the second bracket 4 is similar to that of the first bracket 3. The top of the second bracket 4 is used to carry the electronic device 7 to be tested, such as devices like mobile phones, tablets, music players, etc. The driving component is located inside the base 2, and the driving component can drive one of the first bracket 3 and the second bracket 4 to slide relative to the other. For example, the second bracket 4 can be set as fixed, and the driving component drives the first bracket 3 to move towards the second bracket 4, or the first bracket 3 can be set as fixed. At this time, the driving component drives the second bracket 4 to move towards the first bracket 3. Select which bracket to drive according to needs, or the driving component can also be set to drive both the first bracket 3 and the second bracket 4 to move simultaneously. When it is necessary to use the audio test device 100 to test the sound of an electronic device, the second bracket 4 is kept fixed, the electronic device 7 to be tested is fixed on the top of the second bracket 4, and the audio test equipment 6 is fixed on the top of the first bracket 3. Driven by the driving component, the first bracket 3 moves towards or away from the second bracket 4 along the base according to the setting. In this way, during the audio test of the electronic device, the audio test equipment 6 can automatically adjust the distance from the electronic device as needed, without manual adjustment, avoiding errors caused by manual adjustment, and making the test results more accurate and the test efficiency higher.

[0036] In some implementation manners, such as Figure 1 shown, a guiding portion 9 is provided on the base 2. The guiding portion 9 extends along the arrangement direction of the first bracket 3 and the second bracket 4. The first bracket 3 is slidably connected to the guiding portion 9, and the second bracket 4 is fixed at the other end of the base 2. The guiding portion 9 can be configured as a guide rail. The bottom of the first bracket 3 is connected to the guide rail through a pulley. The driving assembly is connected to the first bracket 3 and then drives the first bracket 3 to slide along the guide rail towards the fixed second bracket 4. Since the audio testing device 6 and the electronic device 7 to be tested are respectively fixed to the tops of the first bracket 3 and the second bracket 4, the adjustment of the distance between the audio testing device 6 and the electronic device 7 to be tested is realized. Optionally, the guiding portion 9 can be configured as a chute. The bottom of the first bracket 3 is connected to the chute through a slider. The driving assembly is connected to the first bracket 3 and then drives the first bracket 3 to slide along the guide rail towards the fixed second bracket 4. Thus, the adjustment of the distance between the audio testing device 6 and the electronic device 7 to be tested is realized. Compared with the case where the guiding portion 9 is not provided, by providing the guiding portion 9 on the base 2 and slidably connecting the first bracket 3 to the guiding portion 9, and fixing the second bracket 4 on the base 2, when using the audio testing device 100 to test the sound of the electronic device, the first bracket 3 can slide more precisely towards the second bracket 4.

[0037] In order to realize the adjustment of the height of the audio testing device 6, such as Figure 1 shown, the first bracket 3 includes: a first fixing portion 31, a first lifting portion 32, and a first lifting driving assembly (not marked in the figure). The first fixing portion 31 is connected to the base 2, and the first fixing portion 31 is fixed in a direction perpendicular to the base 2, but the first fixing portion 31 can move along the guiding portion 9 towards the second bracket 4. The first lifting portion 32 is slidably connected to the upper end of the first fixing portion 31, and the audio testing device 6 is fixed to the top of the first lifting portion 32. The first lifting driving assembly is connected to the first lifting portion 32 to drive the first lifting portion 32 to lift relative to the first fixing portion 31. When it is necessary to adjust the height of the audio testing device 6 relative to the base 2, the first lifting driving assembly can be used to control the first lifting portion 32 to lift relative to the first fixing portion 31. Since the audio testing device 6 is fixed to the top of the first lifting portion 32, the height of the audio testing device 6 relative to the base is adjusted as the first lifting portion 32 lifts. By such a setting, the height of the audio testing device 6 relative to the base 2 can be adjusted, and it can better meet the height requirements of different testers.

[0038] Furthermore, such as Figure 1As shown, the audio test device 100 further includes a first height sensor (not shown in the figure). At the top of the first bracket 3, there is an audio test device 6, and a first height sensor is arranged outside the audio test device 6. The first height sensor can detect the height at which it is located, and the first height sensor is electrically connected to the first lifting drive assembly, so that the signal of the first height sensor can be transmitted to the first lifting drive assembly. Therefore, when the first lifting part 32 is controlled by the first lifting drive assembly to rise or fall, the first height sensor can detect the height at which it is located in real time, so as to obtain the height at which the audio test device 6 is located. In this way, during the use of the audio test device 100, the height at which the audio test device 6 is located can be accurately obtained and fed back to the first lifting drive assembly, so that the accuracy of the experimental results is higher.

[0039] To adjust the height of the electronic device 7 to be tested, as Figure 1 shown, the second bracket 4 includes: a second fixing part 41, a second lifting part 42, and a second lifting drive assembly (not shown in the figure). The second fixing part 41 is connected to the base 2, and the second fixing part 41 is fixed on the base 2. The second lifting part 42 is slidably connected to the upper end of the second fixing part 41, and the electronic device 7 to be tested is fixed on the top of the second lifting part 42. The second lifting drive assembly is connected to the second lifting part 42 to drive the second lifting part 42 to lift relative to the second fixing part 41. When it is necessary to adjust the height of the electronic device 7 to be tested relative to the base 2, the second lifting drive assembly can be used to control the second lifting part 42 to lift relative to the second fixing part 41. Since the electronic device to be tested is fixed to the top of the second lifting part 42, the height of the electronic device to be tested relative to the base 2 is adjusted as the second lifting part 42 rises and falls. By such an arrangement, the height of the electronic device 7 to be tested relative to the base 2 can be adjusted, which can better meet the height requirements of different testers, and the height can be kept consistent with the audio test device 6.

[0040] Further, as Figure 1As shown, the audio test device 100 further includes a second height sensor (not shown in the figure). At the top of the second bracket 4, there is an electronic device fixing component 8. The electronic device fixes the electronic device 7 to be tested from the fixing component 8. A second height sensor (not shown in the figure) is provided on the electronic device fixing component 8. The second height sensor can detect the height at which it is located. The second height sensor is electrically connected to the second lifting drive component, so that the signal of the second height sensor can be transmitted to the second lifting drive component. Therefore, when the second lifting part 42 is controlled by the second lifting drive component to rise or fall, the second height sensor can detect the height at which it is located in real time, so that the height of the electronic device 7 to be tested is kept at the same height as the audio test device. In this way, during the use of the audio test device 100, the height of the electronic device 7 to be tested can be accurately obtained and fed back to the second lifting drive component, thereby making the experimental results more accurate.

[0041] Optionally, as Figure 1 shown, the audio test device 100 further includes a distance measuring sensor 5. The distance measuring sensor 5 can be provided on the audio test device 6 or the electronic device fixing component 8. Taking the distance measuring sensor 5 being provided on the audio test device 6 as an example, the distance measuring sensor 5 is electrically connected to the drive component. The distance measuring sensor 5 can measure the distance between the audio test device 6 and the electronic device fixing component 8 and feed it back to the drive component. During the test, the distance between the audio test device 6 and the electronic device fixing component 8 can be obtained in real time through the distance measuring sensor 5, so that the audio test device 100 can accurately determine and adjust this distance as needed, thereby making the test results more accurate.

[0042] In some implementation manners, as Figure 1 shown, the audio test device 6 includes: an audio receiver 61 and an audio processing unit 62. The audio receiver 61 is used to receive the sound emitted by the electronic device 7 to be tested, and the audio processing unit 62 is used to process the signal of the audio receiver 61. During the audio test of the electronic device, the electronic device is received by the audio receiver 61, and then the audio receiver 61 transmits the signal to the audio processing unit 62. The audio processing unit can transmit the processed signal to the computer through a signal line for use. Compared with directly transmitting the audio signal to the computer, this application adds an audio processing unit 62, first processes the received sound signal and then transmits it to the computer, reducing audio loss and interference, making the accuracy of the sound signal higher during the transmission process, and thus making the test results more accurate.

[0043] To better fix the electronic device 7 to be tested, as Figure 1As shown in the figure, an electronic device fixing assembly 8 is provided at the top of the second bracket 4. The electronic device fixing assembly 8 includes a support panel 81, telescopic jaws 82, and a jaw driving assembly (not marked in the figure). The support panel 81 is connected to the second bracket 4. The telescopic jaws 82 are arranged around the support panel. The jaw driving assembly is connected to the telescopic jaws 82 and controls the telescoping of the jaws. The telescopic jaws 82 can be arranged on the upper and lower sides or the left and right sides of the support panel 81, or one telescopic jaw 82 can be arranged at each of the four sides. The number of jaws can be set to 2, 3, or 4, which can be selected according to needs. During the entire audio test, when an electronic device needs to be placed, the jaw driving assembly controls the telescopic jaws 82 to tighten and hold the electronic device 7 to be tested. The support panel 81 supports the electronic device 7 to be tested, and then the test is carried out. When the electronic device needs to be removed, the jaw driving assembly controls the telescopic jaws 82 to open, and then the tester removes the electronic device. Compared with the fixed elastic jaws, the driven telescopic jaws 82 configured in this application enable the support panel to more conveniently fix the electronic device to be tested, with higher test efficiency. Moreover, the driven telescopic jaws 82 can hold the electronic device 7 to be tested more firmly, avoiding loosening during the test and affecting the test accuracy.

[0044] Further, in order to achieve a better clamping effect, as Figure 1 and Figure 2 shown, a pressure sensor 821 can be arranged on the clamping surface of the telescopic jaws 82. The clamping surface is the surface of the inner surface of the telescopic jaws 82 that contacts the electronic device 7 to be tested, and the pressure sensor 821 is electrically connected to the jaw driving assembly. When the electronic device 7 to be tested is placed on the support panel 81 or removed from the support panel, the pressure sensor 821 arranged on the clamping surface of the telescopic jaws 82 can sense the pressure brought by the electronic device 7 to be tested, and transmit the signal converted from this pressure to the jaw driving assembly. The jaw driving assembly controls the telescopic jaws 82 to clamp or loosen. By arranging the pressure sensor 821 on the clamping surface of the telescopic jaws 82, the telescopic jaws 82 can sense the weight of the electronic device 7 to be tested, so that the jaw driving assembly can control the telescopic jaws 82 to clamp the electronic device 7 to be tested more appropriately, avoiding excessive clamping force and damaging the test equipment, and can protect the telescopic jaws 82 and increase the service life of the telescopic jaws 82.

[0045] Optionally, as Figure 1 shown, the guiding portion 9 can be set as a guide rail or a chute. When the guiding portion 9 is set as a guide rail, the bottom of the first bracket 3 is correspondingly set as a pulley structure, and the first bracket 3 slides on the guide rail through the pulley. When the guiding portion 9 is set as a chute, the bottom of the first bracket 3 is correspondingly set as a slider structure, and the first bracket 3 slides on the chute through the slider.

[0046] In some implementation manners, a rechargeable battery may be disposed in the audio test device 100. For example, a rechargeable battery is disposed in the base 2, and the battery supplies the energy-consuming units of the entire audio test device 100. Compared with the test device that uses a wired connection, by disposing a rechargeable battery in the audio test device 100, the audio test device 100 can be used without an external power supply, and it is not necessary to be limited to the position of the socket, which increases the usage scenarios of the audio test device 100 and makes the audio test device 100 more practical.

[0047] The driving assembly for controlling the first bracket 3 to move back and forth along the guiding portion 9 towards the second bracket 4 includes: a lead screw, a nut, and a motor. The guiding portion 9 is disposed on the base 2; the fixing portion 31 of the first bracket 3 is slidably engaged with the guiding portion 9; the lead screw is disposed on the base 2 and extends along the direction of the guiding portion 9; the nut is fixed to the first fixing portion 31 and is engaged with the lead screw; the motor is connected to the lead screw to drive the lead screw to rotate. When the motor is started to drive the lead screw to rotate, the lead screw can drive the first fixing portion 31 to move back and forth along the guiding portion 9 towards the second bracket 4 through the nut, so as to drive the first bracket 3 to move back and forth along the guiding portion 9 towards the second bracket 4. There are various implementation manners for the driving assembly, as long as linear driving can be achieved. In addition to the motor cooperating with the lead screw and nut transmission scheme in this example, there are also cylinder driving, motor cooperating with gear and rack transmission, etc. The structural principles of the first lifting driving assembly for driving the first lifting portion 32 to lift on the first fixing portion 31 and the second lifting driving assembly for driving the second lifting portion 42 to lift on the second fixing portion 41 are similar to the foregoing driving assembly and will not be elaborated here.

[0048] Optionally, the first bracket 3, the second bracket 4, and the base 2 may be configured with a metal material, such as stainless steel, aluminum alloy, etc. Because the metal material has better durability, compared with plastic or other non-metal materials, by configuring the first bracket 3, the second bracket 4, and the base 2 with a metal material, the audio test device 100 can have better durability and a longer service life.

[0049] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
