Example one
Referring to fig. 1, a flowchart illustrating steps of a volume adjusting method according to a first embodiment of the present invention is shown.
The volume adjusting method provided by the embodiment of the invention is applied to electronic equipment and comprises the following steps:
step 101: and acquiring a first sound signal collected by a microphone.
The first sound signal collected by the microphone is composed of near-end voice, ambient noise and echo, wherein the near-end voice is a second sound signal played by the receiver. In the conversation process, a processor of the electronic equipment analyzes the first sound signal collected by the microphone in real time, and adjusts the volume of the receiver in real time according to the analysis result.
Step 102: an echo signal value and a noise signal value in the first sound signal are determined separately.
The echo signal is a sound signal returned by a second sound signal sent by an earphone of the electronic equipment after passing through the obstacle. The noise signal is noise generated in the environment surrounding the electronic device.
Step 103: and adjusting the volume of the receiver according to the echo signal value and the noise signal value.
The echo signal value can reflect the strength of a second sound signal played by the receiver, and the higher the echo signal value is, the higher the strength of the second sound signal is; the noise signal value can reflect the magnitude of the external noise, the larger the noise signal value is, the larger the external noise is, otherwise, the smaller the noise signal value is, the smaller the external noise is. The user clearly hears the second sound signal played by the receiver, and needs to overcome the external noise and the echo of the second sound signal output by the receiver at the previous moment, so the volume of the receiver needs to be adjusted by combining the echo signal value and the noise signal value, thereby ensuring that the user can clearly hear the second sound signal output by the receiver, namely the call content sent by the opposite terminal device, and preventing surrounding people from hearing the call content.
According to the volume adjusting method provided by the embodiment of the invention, a first sound signal collected by a microphone is acquired; respectively determining an echo signal value and a noise signal value in the first sound signal; according to the volume of the earphone adjusted by the echo signal value and the noise signal value, on one hand, the volume of the earphone can be flexibly adjusted by the electronic equipment, the volume of the earphone does not need to be manually adjusted by a user, the adjustment of the volume of the earphone is instant and accurate, and the use experience of the user can be improved.
Example two

The volume adjusting method provided by the embodiment of the invention is applied to electronic equipment and comprises the following steps:
step 201: and acquiring a first sound signal collected by a microphone.
Step 202: and acquiring a second sound signal to be played by the receiver.
In the process of the communication between the electronic equipment and the opposite terminal equipment, the user of the electronic equipment sends voice information to the opposite terminal equipment and inputs the voice information through the microphone, and the user of the opposite terminal equipment sends the voice information to the electronic equipment and inputs the voice information through the receiver of the electronic equipment. The second sound signal is a sound signal converted from the sound information sent to the electronic equipment by the opposite terminal equipment user.
Step 203: and performing echo signal cancellation processing on the first sound signal according to the second sound signal to obtain a third sound signal and determine an echo signal value in the first sound signal.
And performing echo cancellation on the first sound signal collected by the microphone and the second sound signal to be played by the receiver to obtain the energy of the echo signal collected by the microphone, wherein the energy of the echo signal can be represented by an echo signal value.
And carrying out echo signal elimination processing on the first sound signal according to the second sound signal to obtain a third sound signal. Specifically, an echo signal value in the first sound signal may be determined in dependence on the second sound signal; and subtracting the echo signal value from the first sound signal to obtain a third sound signal.
An adaptive filtering echo cancellation method may be used for performing echo cancellation on the first sound signal, and the schematic diagram of the echo cancellation is shown in fig. 3. As shown in fig. 3, the first sound signal collected by the microphone mainly originates from two paths, where the first path is a sound source including near-end speech and ambient noise, and the second path is an echo of the sound signal emitted by the receiver after encountering an obstacle. Estimating the size of an echo signal in a first sound signal collected by a microphone by using a reference signal, namely a second sound signal to be played by a receiver, and then subtracting the estimated echo signal from the first sound signal collected by the microphone to obtain a third sound signal with echo removed.
Step 204: and carrying out noise estimation on the third sound signal, and determining a noise signal value in the third sound signal.
Any suitable method may be adopted for performing noise estimation on the third sound signal, and this is not particularly limited by the embodiment of the present invention.
Step 205: and adjusting the volume of the receiver according to the echo signal value and the noise signal value.
A manner of adjusting the volume of the handset, optionally in dependence on the echo signal value and the noise signal value, is: calculating the ratio of the echo signal value to the noise signal value; comparing the ratio with a preset value; reducing the volume of the receiver under the condition that the ratio is greater than a preset value; and under the condition that the ratio is smaller than the preset value, increasing the volume of the receiver.
The method for adjusting the volume of the receiver according to the ratio of the echo signal value to the noise signal value can improve the accuracy of volume adjustment.
In a specific implementation process, the preset value can be determined as follows: determining a safe distance; the volume of the receiver is increased while preset noise is played through the receiver, and the increase of the volume of the receiver is stopped when the signal intensity reaches the preset intensity after the preset noise is transmitted for a safe distance; collecting noise played by a receiver through a microphone to obtain a fourth sound signal; and determining the ratio of the first signal value of the fourth sound signal to the second signal value of the preset noise as a preset value.
