Detailed Description
To make the objects, technical solutions and advantages of the present disclosure more apparent, the following embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings. It is to be understood that the described embodiments are merely a subset of the disclosed embodiments and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
Technical solutions disclosed in the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the present disclosure provides an electronic device, including:
an acceleration sensor 101, a vibration unit 102, and a control unit 103.
The control unit 103 includes an interference driving module 1031, and the interference driving module 1031 is connected to the vibration unit 102. Under the state that electronic equipment is in voice communication, interference drive module 1031 outputs interference signal, vibration unit 102 produces the vibration according to the interference signal that receives, the vibration transmits to acceleration sensor 101, at this moment vibration unit 102 to acceleration sensor 101's vibration information acquisition can play the interference effect, acceleration sensor 101 originally received sound signal in the voice communication process will be incomplete, can reach and prevent to utilize acceleration sensor 101 to carry out the purpose of eavesdropping user's sound signal in the voice communication process of using electronic equipment, improved electronic equipment's security.
Specifically, the electronic device may further include a device body 1, the device body 1 may be a portion of the electronic device from which a housing is removed, and the acceleration sensor 101 and the vibration unit 102 are both disposed in the device body 1.
Optionally, the vibration frequency of the vibration unit 102 is greater than or equal to 200% of the sampling frequency of the acceleration sensor 101.
Specifically, when the vibration of the vibration unit 102 is synchronized with the vibration of the mass in the acceleration sensor 101, there is a possibility that the vibration unit 102 does not interfere with the vibration of the mass in the acceleration sensor 101. In order to prevent this, the vibration frequency of the vibration unit 102 may be set separately from the sampling frequency of the acceleration sensor 101, and specifically, the vibration frequency of the vibration unit 102 may be set to be greater than or equal to 200% of the sampling frequency of the acceleration sensor 101, so that it is ensured that the vibration of the vibration unit 102 is not synchronized with the vibration of the mass block in the acceleration sensor 101, and the vibration unit 102 forms a stable interference effect on the vibration of the mass block in the acceleration sensor 101.
In a specific embodiment, the vibration frequency of the vibration unit 102 may be set to 200% of the sampling frequency of the acceleration sensor 101. At this time, the vibration unit 102 has completed two cycles of vibration in one sampling period of the acceleration sensor 101, and the effect of the vibration unit 102 on the high-frequency interference of the sampling information of the acceleration sensor 101 in the sampling period of the acceleration sensor 101 can be achieved on the basis of avoiding the synchronization of the vibration unit 102 and the vibration of the mass block in the acceleration sensor 101.
Optionally, the vibration unit 102 is a linear motor.
In particular, a linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. The linear motor has a simple structure, the size and the vibration parameters can be flexibly adjusted, the requirement of a miniature vibration component can be met, the linear motor can be widely applied to various large, medium and small electronic equipment, and the vibration information sampling of the acceleration sensor 101 can be effectively interfered. In addition, the vibration unit 102 of the embodiment of the disclosure may also select a vibration motor originally of the electronic device, which is not limited by the embodiment of the disclosure.
Optionally, the interference signal is generated according to a sound signal of the electronic device during a voice communication process.
Specifically, the purpose of the embodiment of the present disclosure is to prevent the acceleration sensor 101 from eavesdropping a sound signal of a user during a voice communication process, and utilize an interference signal generated by a sound signal of an electronic device during the voice communication process, where the interference signal drives the vibration unit 102 to vibrate, and the vibration generated by the vibration unit 102 is further transmitted to the acceleration sensor 101, so that the sound signal received by the acceleration sensor 101 can be interfered in a targeted manner, thereby achieving the purpose of effectively preventing eavesdropping.
Optionally, the sound signal includes a sound signal emitted by a receiver and/or a sound signal received by a microphone.
Specifically, when the electronic device performs an anti-eavesdropping function, the electronic device mainly aims at sound signals in a voice communication process, that is, voices made by a user and voices heard by the user, and does not include non-voice call information such as music, video or game sound. The sound signals emitted by the receiver and received by the microphone are the voice heard by the user and the voice emitted by the user. Therefore, the interference driving module 1031 can be prevented from outputting interference information under the condition of non-voice call sounding, the effective output of the interference driving module 1031 is ensured, and the interference efficiency of the vibration unit 102 on the acceleration sensor 101 is also improved.
Optionally, the vibration frequency and the vibration amplitude of the interference signal are equal to both the vibration frequency and the vibration amplitude of the sound signal, and the vibration phase of the interference signal and the vibration phase of the sound signal are different by 180 °.
Specifically, the acceleration sensor 101 can receive vibration information of the sound signal, and the vibration unit 102 generates vibration according to the received interference signal. Under the condition that the vibration frequency and the vibration amplitude of the interference signal and the vibration phase of the sound signal are equal, and the vibration phase of the interference signal and the vibration phase of the sound signal are different by 180 degrees, the mass block in the acceleration sensor 101 and the vibration unit 102 can vibrate in opposite directions, and at this time, the vibration information intensity acquired by the acceleration sensor 101 can be mutually offset due to the action of the opposite vibration, so that the vibration information acquired by the acceleration sensor 101 is reduced or completely avoided.
Optionally, the interference signal is a noise signal randomly generated by the interference driving module 1031.
Specifically, the noise signal may drive the vibration unit 102 to vibrate randomly, so as to randomly interfere with the information collected by the acceleration sensor 101. Similarly, when two users perform voice communication, the surrounding of the users has obvious loud noises such as television sound, broadcast sound, traffic whistling and the like, and at the moment, one user cannot easily receive voice information of the other user, so that the communication purpose of the other user is difficult to accurately understand. In the embodiment of the present disclosure, the random vibration of the vibration unit 102 may be transmitted to the acceleration sensor 101, so that it is difficult for the acceleration sensor 101 to accurately receive the voice information of the sound signal, and the purpose of preventing eavesdropping is achieved.
Alternatively, the vibration unit 102 is disposed in the apparatus main body 1 adjacent to the acceleration sensor 101.
The vibration energy generated by the vibration unit 102 is transmitted to the acceleration sensor 101, and specifically, the vibration unit 102 and the acceleration sensor 101 are connected through a hardware medium, and the hardware medium can transmit the vibration generated by the vibration unit 102; the vibration unit 102 and the acceleration sensor 101 may be arranged in the device main body 1 adjacent to each other, so that a vibration transmission medium is not needed, and the vibration generated by the vibration unit 102 can be directly transmitted to the acceleration sensor 101, thereby achieving the effect of timely and efficiently interfering the information acquisition of the acceleration sensor 101.
Referring to fig. 2, an embodiment of the present disclosure further provides an anti-eavesdropping method applied to the electronic device, including:
s101, controlling an interference driving module to output an interference signal under the condition of voice communication;
and S102, generating vibration by the vibration unit according to the interference signal, and transmitting the vibration to the acceleration sensor.
Specifically, the voice communication in step S101 includes a voice call, a video call, or other communication modes requiring voice interaction.
According to the anti-eavesdropping method, the vibration unit is driven to vibrate by the interference signal output by the interference driving module, the vibration generated by the vibration unit can be effectively transmitted to the acceleration sensor, the vibration of the acceleration sensor is interfered, the original sound information received by the acceleration sensor can be damaged, and the purpose of preventing eavesdropping by utilizing the acceleration sensor is achieved. The anti-eavesdropping method is simple to operate, sensitive information of a terminal user is prevented from being leaked, and the safety of the electronic equipment is improved.
Optionally, the control unit sends a control instruction for controlling the interference driving module according to the received encrypted call instruction.
Specifically, before the control unit sends the control instruction, the electronic device may select the encrypted call instruction after turning on the voice call. The sending of the encrypted call instruction can be that the control unit selects according to the importance of the voice call information, or can be that a user independently selects which calls are encrypted calls, and then sends the encrypted call instruction, and finally achieves the purpose of eavesdropping prevention by interfering the acquisition information of the acceleration sensor through the vibration unit.
Optionally, referring to fig. 3, an electronic device further includes a control module 1032 configured to control the interference driving module 1031 to output an interference signal when the electronic device is in voice communication.
Specifically, the interference signal may be generated and controlled by the interference driving module 1031 itself and output to the outside, or may be generated and controlled by the control module 1032 and then output to the outside by the interference driving module 1031, so as to achieve flexible control of the interference signal.
