The capacitive acoustic control method, device, apparatus and medium provided in the embodiments of the present application are described in detail with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Fig. 1 is a schematic flowchart of a capacitive acoustic control method according to an embodiment of the present application. As shown in fig. 1, the capacitive acoustic control method may include:
s101: carrying out sound source positioning by using a microphone array, and determining the capacitance for emitting sound;
s102: and under the condition that the power supply of the capacitor which emits the sound is in the low power consumption mode, controlling the power supply of the capacitor which emits the sound to exit the low power consumption mode so as to control the capacitor sound.
Specific implementations of the above steps will be described in detail below.
In the embodiment of the application, the sound source is positioned by using the microphone array, the capacitor which emits sound is determined, and then the power supply of the capacitor is controlled to exit from the low power consumption mode under the condition that the power supply is in the low power consumption mode, so that the problem of capacitance sound can be solved. The PCB does not need to be modified, the noise reduction capacitor with higher price does not need to be used, and the cost for solving the capacitive sound can be reduced.
The embodiment of the application does not limit the specific process of utilizing the microphone array to perform sound source localization and determining the capacitance for emitting sound, and specifically refers to the process of performing sound source localization through the microphone array in the related art.
In some possible implementations of embodiments of the present application, S101 may include at least one of:
under the condition that the distance between the electronic equipment provided with the microphone array and a user is smaller than a distance threshold value, positioning a sound source by using the microphone array, and determining the capacitance for emitting sound;
under the condition that human ears or human heads exist in the images acquired by the electronic equipment, the microphone array is utilized to carry out sound source positioning, and the capacitance for emitting sound is determined.
In some possible implementations of embodiments of the present application, the distance of the electronic device to the user may be detected by a distance sensor.
In some possible implementations of the embodiments of the present application, in detecting the distance from the electronic device to the user by using the distance sensor, a Time of flight (TOF) method may be used to detect the distance from the electronic device to the user.
The embodiment of the present application does not limit the specific manner for detecting the distance from the electronic device to the user, and any available manner may be applied to the embodiment of the present application.
In the embodiment of the application, when the electronic equipment is far away from the user, even if capacitive sound occurs, the capacitive sound cannot be easily heard by the user, and the capacitive sound does not need to be controlled. When the electronic device is close to the user, the capacitive sound is easily heard by the user, and the capacitive sound needs to be controlled.
In the embodiment of the application, the capacitor sound is controlled only when the electronic equipment is close to the user, so that the problem that when the electronic equipment is far away from the user, the power supply for controlling the capacitor exits from a low power consumption mode and the power consumption of the power supply is high can be solved.
In some possible implementations of the embodiment of the present application, a camera of an electronic device may be used to collect an image, and then it is determined whether a human ear or a human head exists in the image collected by the camera. When no human ear or head exists in the image acquired by the camera (for example, the electronic device is in a user pocket), it indicates that the electronic device is not close to the human ear, and the capacitance sound does not need to be controlled; when the human ear or the human head exists in the image collected by the camera, the electronic equipment is close to the human ear, and the capacitance sound is easy to hear by a user and needs to be controlled.
The embodiment of the present application does not limit the manner of detecting whether the human ear or the human head exists in the image, and any available manner may be applied to the embodiment of the present application. For example, ear features are extracted by a high-order invariant matrix to perform ear recognition, and head detection recognition is performed by OpenCV.
In some possible implementations of the embodiment of the present application, a camera of an electronic device may be used to acquire an image, and then it is determined whether a human ear or a human head exists in the image acquired by the camera. When the electronic equipment is close to the user and no human ear or head exists in the image acquired by the camera (for example, the electronic equipment is in a user pocket), it indicates that the electronic equipment is not close to the human ear, and at this time, the capacitance sound does not need to be controlled; when the human ear or the human head exists in the image collected by the camera and the distance between the electronic equipment and the user is short, the electronic equipment is close to the human ear, and the capacitance sound is easy to hear by the user and needs to be controlled.
In the embodiment of the application, the capacitor sound is controlled only when the electronic equipment is close to the user and the human ear or the human head exists in the image, so that the problem that the power supply for controlling the capacitor exits from the low power consumption mode and the power consumption of the power supply is high when the electronic equipment is close to the user and the human ear or the human head does not exist in the image can be solved.
In some possible implementations of embodiments of the present application, S102 may include at least one of:
adjusting the working mode of a power supply of a capacitor which emits sound to be a Pulse Width Modulation (PWM) mode;
and adjusting the switch state of the power supply of the capacitor which emits the sound to be a normally open state.
In this application embodiment, the power switch frequency of PWM mode work is invariable, and the power of PWM mode work can output steady voltage, and the ripple is less, can reduce the vibrations of electric capacity, and then reduces the electric capacity sound.
In the embodiment of the application, when the power supply of the capacitor is switched on and off, the voltage applied to two ends of the capacitor has larger variation amplitude, the vibration amplitude of the capacitor is larger, and the capacitor sound is more obvious. The power supply of the capacitor which makes sound is adjusted to be in a normally open state, at the moment, the voltage applied to the two ends of the capacitor cannot change, the capacitor does not vibrate any more, and the capacitor makes sound messages.
In some possible implementations of the embodiments of the present application, S102 may include: and controlling the power supply to exit the low power consumption mode under the condition that the first volume of the capacitive sound is greater than the first volume threshold.
In the embodiment of the application, when the capacitive sound is low, the capacitive sound is not heard by the user generally, and in this case, the capacitive sound does not need to be controlled. When the capacitive sound is high, it may be audible to the user, and the capacitive sound needs to be controlled.
In the embodiment of the application, the capacitive sound is controlled only when the capacitive sound is high and is possibly heard by a user, so that the problem that the power supply for controlling the capacitor exits from a low power consumption mode and the power consumption of the power supply is high when the capacitive sound is low can be solved.
In some possible implementations of the embodiment of the present application, before S102, the method for controlling capacitive sound, provided by the embodiment of the present application, may further include: acquiring a second volume of the background noise; and determining a first volume threshold according to the second volume.
The background noise is also called background noise (simply referred to as "background noise") and refers to ambient noise other than the noise source to be measured.
In some possible implementations of embodiments of the present application, the volume of the background noise may be obtained by the microphone array, and then the corresponding volume threshold may be determined according to the volume of the background noise.
In some possible implementations of embodiments of the present application, determining the first volume threshold from the second volume includes: setting the first volume threshold value as a third volume when the second volume is greater than or equal to the second volume threshold value; and under the condition that the second volume is smaller than the second volume threshold, setting the first volume threshold as a fourth volume, wherein the fourth volume is smaller than the third volume.
It is understood that the larger the volume of the background noise, the less easily the capacitive sound is heard by the user, and the smaller the volume of the background noise, the more easily the capacitive sound is heard by the user.
When the volume of the background noise is larger than or equal to the second volume threshold, the environment is noisy, the capacitance sound is not easy to hear by the user, and if the capacitance sound is heard by the user, the capacitance sound is large, and the capacitance sound needs to be controlled.
When the volume of the background noise is less than the second volume threshold, it indicates that the environment is quiet, and since the capacitive sound is easily heard by the user, the capacitive sound also needs to be controlled, and when the capacitive sound is small, the capacitive sound may be heard by the user.
In some possible implementations of embodiments of the present application, different volume thresholds may be set for different environments. Specifically, in the case where the second volume is greater than or equal to the second volume threshold, the first volume threshold is set to X (i.e., the third volume); in the case where the second volume is less than the second volume threshold, the first volume threshold is set to Y (i.e., a fourth volume), where Y is less than X.
The capacitive sound control method provided by the embodiment of the present application is described below by a specific example. As shown in fig. 2, fig. 2 is a schematic diagram of a process for controlling capacitive sound according to an embodiment of the present application. The process of controlling the capacitive sound comprises:
s201: the distance sensor detects the distance from the electronic equipment to a user;
s202: starting a camera to collect an image under the condition that the distance from the electronic equipment to the user is smaller than a distance threshold value;
s203: carrying out ear recognition or head recognition on the image acquired by the camera;
s204: detecting background noise, capacitance sound and capacitance sound source positioning by using a microphone array under the condition that human ears or human heads exist in an image acquired by a camera, and determining the capacitance of the emitted sound;
s205: determining a power supply of a capacitor according to the capacitor which emits the sound;
s206: determining a corresponding volume threshold according to the volume of the background noise;
s207: and controlling the power supply of the capacitor which emits the sound to exit the low power consumption mode under the condition that the volume of the capacitor sound is larger than the determined volume threshold value.
