Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.
[0042] A first aspect of an embodiment of the present invention provides an earphone testing device, which controls the offset of an earphone at a preset angle to improve the accuracy and efficiency of earphone testing.
[0043] The earphones may be various earphone devices, such as open-back earphones, on-ear headphones, in-ear headphones, etc.
[0044] Among them, such as Figure 1 As shown, the headphone test setup includes:
[0045] A test platform 10 is provided with a drive motor 11. The drive motor 11 is triggered to rotate by a motor drive signal and drives the test platform 10 to rotate in a first direction and / or a second direction, wherein the first direction intersects the second direction.
[0046] A human head model 20 is mounted on the test platform 10 and is provided with an artificial ear 21 for placing the earphone to be tested. The human head model 20 rotates with the test platform 10;
[0047] The motor driving circuit 30 is connected to the driving motor 11 and is triggered by the motor control signal to output a motor driving signal;
[0048] The control circuit 40 is connected to the motor drive circuit 30 and is used to receive angle information and output corresponding motor control signals to synchronously rotate the angle of the human head model 20 to a preset angle.
[0049] In this embodiment, a human head model 20 is molded according to the shape of a human head. An artificial ear 21 is integrally formed on the human head model 20. The artificial ear 21 is provided with an ear canal. Open-ear headphones, head-mounted headphones, and in-ear headphones can be placed outside the artificial ear 21 or accommodated in the ear canal. The lower part of the human head model 20 is installed on the test platform 10. The test platform 10 is provided with a mounting portion 14 for mounting the human head model 20. The test platform 10 is also provided with a drive motor 11. The drive motor 11 rotates in a first direction and / or a second direction according to a received motor drive signal, and drives the mounting portion 14 and the human head model 20 to rotate accordingly. The first direction and the second direction can be set according to needs. In an optional embodiment, the first direction is a horizontal direction and the second direction is a vertical direction.
[0050] When the human head model 20 rotates in the horizontal direction, the simulation is equivalent to the shaking movement of the human head. When the human head model 20 rotates in the vertical direction, the simulation is equivalent to the nodding movement of the human head.
[0051] When testing the headphones, the tester can place the headphones on the artificial ear 21 of the human head model 20. At the same time, the control module such as the remote control and the host computer 50 outputs angle information to the control circuit 40. The control circuit 40 analyzes the angle information, determines the rotation angle and rotation duration of the drive motor 11, and outputs a corresponding motor control signal to the motor drive circuit 30. The motor drive circuit 30 outputs a motor drive signal of corresponding magnitude and duration to the drive motor 11 based on the received motor control signal. The drive motor 11 rotates according to the received motor drive signal, driving the test mounting portion 14, the human head model 20, and the headphones placed on the human head model 20 to rotate together. After the test device moves to a preset angle matching the angle information, the motor drive signal stops outputting to the drive motor 11, and the drive motor 11 remains at the current preset angle position. The internal sensor of the headphones placed on the artificial ear 21 can collect position information, audio information, etc. during the movement, realizing spatial audio, head tracking, and other information collection. The collected information is sent to the signal receiving module, thereby completing the spatial audio, head tracking, and other functions integrated into the headphones.
[0052] At the same time, after receiving the next angle information, the control circuit 40 switches to output different motor control signals, thereby controlling the human head model 20 and the headphones placed on the human head model 20 to rotate to another preset angle again, completing the next posture synchronization work or the preset number of tests.
[0053] By adopting the headphone testing device, automatic rotation and maintenance of the preset angle can be achieved, which improves the testing accuracy of the headphone, reduces the testing time, and improves the testing efficiency.
[0054] At the same time, the earphone testing device can also realize the factory function verification of the earphone. The earphone that has just been shipped is placed on the artificial ear 21. At the same time, the control circuit 40 receives the angle information of the test system and controls the drive motor 11 to rotate through the motor drive circuit 30. The drive motor 11 drives the test mounting part 14, the human head model 20 and the earphone placed on the human head model 20 to rotate together, and stops outputting the motor drive signal to the drive motor 11 after moving to a preset angle matching the angle information. The drive motor 11 remains at the current preset angle position. The internal sensor of the earphone placed on the artificial ear 21 can collect the angle information during the movement and compare the collected angle information with the specified angle information. When the angle information of the two is within the error range, it indicates that the earphone collection function is normal, otherwise it is abnormal.
[0055] The test platform 10 may be provided with a corresponding mounting portion 14, one or more motors, and in an optional embodiment, such as Figure 2 As shown, the test platform 10 includes:
[0056] Base 12;
[0057] The rotating portion 13 is mounted on the base 12;
[0058] The first drive motor 111 is installed on the side of the rotating portion 13 facing the base 12. The first drive motor 111 is triggered to rotate by the first motor drive signal and drives the rotating portion 13 to rotate in the first direction;
[0059] The second drive motor 112 is installed on the other side of the rotating portion 13 facing away from the base 12 and moves along the first direction with the rotating portion 13. The second drive motor 112 is triggered by the second motor drive signal to rotate along the second direction;
[0060] The mounting portion 14 has a first end mounted on the second drive motor 112 , and a second end for mounting the human head model 20 . The mounting portion 14 rotates in the first direction and / or the second direction when the first drive motor 111 and the second drive motor 112 rotate.
[0061] In this embodiment, the base 12 can be fixedly mounted on the corresponding platform by means of screw locking, bonding, etc., the end of the rotating portion 13 facing the base 12 is fixedly mounted on the base 12 by means of a positioning column or a screw, and the other end of the rotating portion 13 facing away from the base 12 can rotate. The first drive motor 111 is mounted on the base 12 and fixedly mounted with the end of the rotating portion 13 facing the base 12. The second drive motor 112 is mounted on the side of the rotating portion 13 facing away from the base 12 and rotates along with the rotating portion 13 when it rotates. The first end of the mounting portion 14 is mounted on the second drive motor 111. The mounting portion 14 is mounted on the rotor of the first drive motor 111 and rotates along with the rotor of the second drive motor 112. The second end of the mounting portion 14 is used to mount the human head model 20. When the first drive motor 111 rotates, the rotating portion 13 rotates in the first direction, and drives the second drive motor 112, the mounting portion 14 and the human head model 20 mounted on the rotating portion 13 to rotate in the first direction. When the second drive motor 112 rotates, the second drive motor 112 drives the mounting portion 14 and the human head model 20 to rotate in the second direction, thereby simulating the shaking and nodding movements of the human head.
[0062] When testing the earphones, the tester can place the earphones on the artificial ear 21 of the human head model 20. At the same time, the control module such as the remote control and the host computer 50 outputs the angle information to the control circuit 40. The control circuit 40 analyzes the angle information, determines the rotation angle and rotation duration of the drive motor 11, and outputs the corresponding motor control signal to the motor drive circuit 30. The motor drive circuit 30 outputs a first motor drive signal of corresponding size and duration to the first drive motor 111 and / or outputs a second motor drive signal of corresponding size and duration to the second drive motor 112 according to the received motor control signal. After receiving the first motor drive signal, the first drive motor 111 rotates in the horizontal direction and drives the rotating part 13 to rotate in the horizontal direction, thereby driving the upper second drive motor 112, the mounting part 14, the human head model 20 and the earphones placed on the human head model 20 to rotate together. Rotate horizontally, and / or, the second drive motor 112 rotates in the vertical direction after receiving the second motor drive signal, and drives the upper mounting part 14, the human head model 20 and the headphones placed on the human head model 20 to rotate in the vertical direction together, thereby simulating the shaking and nodding movements of the human head. After moving to a preset angle matching the angle information, the control circuit 40 stops outputting the motor control signal, and the motor drive circuit 30 stops outputting the motor drive signal to the first drive motor 111 and the second drive motor 112. The first drive motor 111 and the second drive motor 112 remain at the current preset angle position. The internal sensor of the headphones placed on the artificial ear 21 can collect position information, audio information, etc. during the movement, realize spatial audio, head tracking and other information collection, and the collected information is sent to the signal receiving module, thereby completing the spatial audio, head tracking and other functions integrated in the headphones.
[0063] Among them, the first drive motor 111 and the second drive motor 112 can adopt corresponding types of motors, such as a stepper motor, an asynchronous motor, etc. In an optional embodiment, the first drive motor 111 and the second drive motor 112 are stepper motors. A stepper motor is an electric motor that converts an electrical pulse signal into a corresponding angular displacement or linear displacement. Each time a pulse signal is received, the stepper motor rotates an angle or moves forward one step. The angular displacement or linear displacement output by the stepper motor is proportional to the number of input pulses, and the rotation speed is proportional to the pulse frequency. By controlling the stepper motor, the human head model 20 and the headphones placed on the human head model 20 can be moved to a preset angle, thereby improving the test accuracy.

[0065] The first motor driver 31 is connected to the control circuit 40 and the first drive motor 111 respectively. The first motor driver 31 is triggered by the motor control signal to output a first motor drive signal;
[0066] The second motor driver 32 is connected to the control circuit 40 and the second drive motor 112 respectively. The second motor driver 32 is triggered by the motor control signal to output a second motor drive signal.
[0067] In this embodiment, the first motor driver 31 is connected to the first drive motor 111 via a signal line, and the second motor driver 32 is connected to the second drive motor 112 via a signal line. The first motor driver 31 and the second motor driver 32 are also connected to the control circuit 40 via signal lines, respectively. After receiving the angle information, the control circuit 40 outputs a first motor control signal to the first motor driver 31 via the signal line, and outputs a second motor control signal to the second motor driver 32 via the signal line. After receiving the first motor control signal, the first motor driver 31 converts and outputs a corresponding first motor drive signal to the first drive motor 111, and drives the first drive motor 111 to rotate horizontally. After receiving the second motor control signal, the second motor driver 32 converts and outputs a corresponding second motor drive signal to the second drive motor 112, and drives the second drive motor 112 to rotate vertically, thereby driving the headphones on the human head model 20 to rotate to a preset angle.

After moving to a preset angle matching the angle information, the output of the motor drive signal to the drive motor 11 is stopped, and the drive motor 11 remains at the current preset angle position. The internal sensor of the headphones placed on the artificial ear 21 can collect position information, audio information, etc. during the movement process to realize spatial audio, head tracking, and other information collection. The collected information is sent to the signal receiving module, thereby completing the spatial audio, head tracking, and other functions integrated in the headphones.
