Specifically, the key 11 generates a corresponding sound signal when pressed, and the microphone 31 may collect the sound signal in real time, transmit the collected sound signal to the circuit board 30, and perform key identification by the circuit board 30.
The electronic device may be a sound box, the microphone 31 may be a microphone 31 disposed in the sound box, and the microphone 31 may realize a function of collecting a sound signal generated when the key 11 is pressed, and may also realize other functions of the sound box.
In the technical solution provided in this embodiment, since the electronic device does not need the key 11 to act on the contact, the circuit board 30 can obtain the signal generated when the key 11 is pressed through the microphone 31, thereby avoiding the situation that the key cannot be identified due to the fact that the contact is worn and an accurate electrical signal cannot be generated, and improving the reliability of the electronic device.
Alternatively, in order to prevent liquid or static electricity from penetrating into the inside of the electronic device through the gap between the key 11 and the key housing (casing 10), thereby causing damage or malfunction of the electronic device, the key 11 may be isolated from the circuit board 30 inside the casing 10, and the following description is made by way of two exemplary embodiments:
in the first embodiment, a groove (not shown) is recessed at a position where the key is disposed on the outer surface of the housing 10, and the key 11 is disposed inside the groove.
To further improve the isolation effect, a recess (not shown) is integrally formed with the housing 10, and the key 11 is disposed in the recess. Specifically, the key 11 may include a key foot, a return spring and a key cap, and the key cap of the key 11 is connected with the key foot through the return spring; the user can press the key cap of the key 11, so that the return spring generates elastic deformation, and when the key cap is pressed to the maximum pressing distance, the key cap collides with the key foot, so that a corresponding sound signal is generated, and the sound signal is a recognition basis for the circuit board 30 to recognize the key 11. The key cap of the key 11 may be higher than the outer surface of the casing 10 when being disposed, or may be flush with the outer surface of the casing 10, which is not limited herein.
In the second embodiment, a spacer 20 covering the circuit board 30 is disposed between the housing 10 and the circuit board 30; the housing 10 is provided with a through hole (not shown) through which the key foot is connected to the spacer 20.
The spacer 20 in this embodiment may be a spacer, the area of the spacer 20 is greater than or equal to that of the circuit board 30, and the projection of the spacer 20 in the vertical direction covers the projection of the circuit board 30 in the vertical direction. Specifically, the key 11 may include a key foot, a return spring, and a key cap, and the key cap of the key 11 is connected with the key foot through the return spring. The key cap of the key 11 may be higher than the outer surface of the casing 10 when being disposed, or may be flush with the outer surface of the casing 10, which is not limited herein.
By isolating the keys 11 of the electronic device from the circuit board 30, liquid or static electricity is prevented from permeating into the electronic device through gaps between the keys 11 and the key shell (shell 10), so that the electronic device is prevented from being damaged or being out of service.
Optionally, the microphone 31 may be directly below the key 11 or the microphone 31 may also detect a sound signal between two keys 11, that is, the position of the projection of the key 11 on the circuit board 30 coincides with the position of the microphone 31; or the number of the microphones 31 and the keys 11 is at least two, the keys 11 are arranged at intervals, and the microphones 31 are arranged between any two keys 11.
The sound signals collected by the different microphones 31 may have differences when the keys 11 are pressed, and the arrangement of the different keys 11 may also affect the process of the circuit board 30 for identifying the keys 11.
When the microphone 31 is disposed directly below the key 11, the microphone 31 directly below the pressed key 11 may acquire the highest peak of the sound waveform of the sound signal, and the peaks of the sound waveforms of the sound signals acquired by the remaining microphones 31 decrease as the distance between the microphone 31 and the key 11 increases, that is, the larger the distance between the microphone 31 and the key 11 is, the smaller the peak of the sound waveform acquired by the microphone 31 is. Therefore, the circuit board 30 can identify the pressed key 11 from the peak of the sound signal collected by the microphone 31.
When the microphones 31 are disposed in the middle of two keys 11, that is, there are two microphones 31 with the same distance to the keys 11 and the distance is the smallest in one key 11, the sound waveforms of the sound signals collected by the two microphones 31 corresponding to the pressed key 11 are similar, and the sound waveforms of the sound signals collected by the other microphones 31 decrease as the distance between the microphone 31 and the key 11 increases. Therefore, the circuit board 30 may determine a corresponding preset waveform group according to the sound waveform collected by each microphone 31, and determine the pressed key 11 according to the corresponding preset waveform group.
By setting the position relationship between the microphone 31 and the key 11, the microphone 31 can acquire the sound waveform meeting the identification condition, thereby improving the reliability of the electronic device.
