Before the improvement of the present application, the position of the microphone in the audio electronic device is fixed. For this reason, when the wind blows to the microphone in the environment, the microphone will receive obvious wind sound, which is what we often call wind noise; especially as for audio electronic devices being sports glasses, they need to be used daily during outdoor running and cycling. During their use, the problem of wind noise is particularly obvious.
In view of this, the present application provides an audio electronic device.
Please referring to
What needs to be pointed out here is that, theoretically, when the microphone 2 moves in the pipeline 11, the pickup of the voice by the microphone 2 will also be affected, but the impact on the voice is smaller than the impact on the wind noise. Therefore, in this design, only the wind noise value can be picked up to adjust the position of the microphone 2. Obviously, in an embodiment of the present application, the voice value of the microphone 2 at the current position can also be obtained, and then the position of microphone 2 is determined according to the voice value and the value of the microphone 2.
The microphone 2 is movably and adjustably provided in the pipeline 11 along the length direction of the pipeline 11. There is no limitation in this design on how to adjust the position of the microphone 2. The position of the microphone 2 can be adjusted manually, so that the user can choose a suitable position according to the size of the wind noise. In the embodiment of the present application, the audio electronic device 100 also includes a driving device 3 and a control device 4. The driving device 3 and the microphone 2 are connected drivingly to drive the movement of the microphone 2, and the control device 4 is electrically connected to the driving device 3. The control device 4 includes a memory, a processor, and the wind noise control program of the microphone 2 of the audio electronic device 100 stored in the memory. The processor executes the wind noise control program of the microphone 2 of the audio electronic device 100 to implement the following wind noise control method for the microphone 2 of the audio electronic device 100:
In an embodiment, when the wind noise at the current position is greater than the first set value, the driving device 3 is controlled to drive the microphone 2 to move until the wind noise at the current position of the microphone 2 is less than the second set value. The above step includes:
In an embodiment, in the step of obtaining the wind noise picked up by the microphone 2 at the current position of the microphone 2 every time a set condition is reached, the set condition includes the microphone 2 moving a set distance.
In an embodiment, when the wind noise at the current position is greater than the first set value, the driving device 3 is controlled to drive the microphone 2 to move until the wind noise at the current position of the microphone 2 is less than the second set value. After the above step, the method also includes:
In an embodiment, after the step of re-obtaining the wind noise picked up by microphone 2 at the current position of microphone 2, the method includes:
In one embodiment of the present application, the driving device 3 drives the microphone 2 to move. The specific structure of the driving device 3 is not limited. In the embodiment of the present application, the pipeline 11 is provided in an arc shape. The driving device 3 includes a rotation device 31 (specifically a motor, more specifically a stepper motor) and a connection rod 32. The connection rod 32 extends along the radial direction of the rotation shaft of the rotation device 31; one end of the connection rod 32 is connected to the rotation shaft of the rotation device 31, and the other end is connected to the microphone 2. Specifically, a long groove is provided on one side wall of the pipeline 11, and one end of the connection rod 32 passes through the long groove and is rotatably connected to the microphone 2.
In addition, the microphone 2 is also electrically connected to the control device 4, which may be wireless or wired. In the case of wired connection, the microphone 2 and the control device 4 are connected through a cable, and sufficient length is reserved for the cable to prevent the cable from moving along with the microphone 2 when it moves.
Obviously, the present application adjusts the wind noise by adjusting the position of the microphone 2 in the pipeline 11. Obviously, the opening size of the pipeline 11 can be controlled at the pipeline 11, so as to reduce the wind noise by adjusting the position.
The present application also provides a wind noise control method for the microphone 2 of the audio electronic device 100.
Step S10: obtaining the wind noise at the current position of the microphone 2 picked up by the microphone 2. Specifically, the microphone 2 will pick up the wind noise signal, and the control device 4 can obtain the wind noise value according to the wind noise signal;
Step S20: when the wind noise at the current position is greater than the first set value, controlling the driving device 3 to drive the microphone 2 to move until the wind noise at the current position of the microphone 2 is less than the second set value; the second set value is less than or equal to the first set value. For example, in an embodiment of the present application, the first set value is 60 dB and the second set value is 40 dB.
In the technical solution provided by the present application, the wind noise control method for the microphone 2 of the audio electronic device 100 includes the following steps: obtaining the wind noise at the current position of the microphone 2 picked up by the microphone 2; when the wind noise at the current position is greater than the first set value, the driving device 3 is controlled to drive the microphone 2 to move until the wind noise at the current position of the microphone 2 is less than the second set value; the second set value is less than or equal to the first set value. That is, in the technical solution of the present application, when the wind noise at the current position of the microphone 2 is large, the driving device 3 is controlled to drive the microphone 2 to move, so that the wind noise at the position of the microphone 2 is at a smaller wind noise value, that is, smaller than the second set value. At this time, when speaking through microphone 2, the wind noise value is smaller and has less impact on the voice.
In an embodiment of the present application, step S20 includes:
Step S21: when the wind noise at the current position is greater than the first set value, controlling the driving device 3 to drive the microphone 2 to move;
Step S23: determining whether the wind noise at the current position is less than the second set value;
Step S24: if yes, controlling the driving device 3 to stop working.
In an embodiment of the present application, after step S20, the method further includes: re-obtaining the wind noise at the current position of the microphone 2 picked up by the microphone 2, that is, returning to step S10 to start the next cycle.
In an embodiment of the present application, after the step of re-obtaining the wind noise at the current position of the microphone 2 picked up by the microphone 2, the method further includes: when the wind noise at the current position is less than a third set value, controlling the microphone 2 to move to the initial position; the third set value is smaller than the second set value. For example, the third set value can be 10 dB. In this way, when the wind noise is small, the microphone 2 is moved to the initial position to maintain a better voice effect.
