Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present application clearer and clearer, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In order to solve the problems of poor voice communication quality and low user experience in the related sound wave transmission method, an embodiment of the present application provides a sound wave transmission method, which may be applied to, but is not limited to, a first sound wave receiving device, and a flow of the method is as shown in fig. 1, and includes the following steps:
s11: in the process of carrying out voice communication with second sound wave receiving equipment, if at least two sound waves are received, whether the at least two sound waves carry first characteristic information or not is detected.
In offices, homes, and other places, there may be multiple terminals simultaneously, and multiple terminals may all sound, for example, in a home environment, as shown in fig. 2, there are terminals such as a television, a mobile computer, and multiple mobile phones, and if the television is playing a video program at this time, the mobile computer is playing music, a user uses a first sound wave receiving device to perform voice communication with a second sound wave receiving device in a different place, during the voice communication, the first sound wave receiving device receives multiple sound waves, and in order to perform voice communication with the second sound wave receiving device better, the first sound wave receiving device needs to filter out part of the sound waves, and at this time, it is necessary to detect whether at least two sound waves carry first feature information.
The first sound wave receiving device and the second sound wave receiving device can be terminals such as a mobile computer and a mobile phone, can be voice communication initiators, and can also be voice communication receivers. The first characteristic information may be selected according to actual needs, and may be, but is not limited to, fingerprint information, identification information of the terminal, and the like.
S12: and selecting the sound waves to be filtered from the sound waves carrying the first characteristic information.
The sound wave generated by the sound wave generating device may carry the first characteristic information, and the sound wave generated by the user may not usually carry the first characteristic information.
In the process of voice communication between the first sound wave receiving device and the second sound wave receiving device, sound waves emitted by the user to be transmitted may be interfering sound waves, and interfering sound waves may be sound waves to be filtered, that is, sound waves carrying the first characteristic information may be sound waves to be filtered, so that the sound waves to be filtered can be selected from the sound waves carrying the first characteristic information.
S13: and after the sound waves to be filtered are filtered out from the at least two sound waves, the residual sound waves are transmitted to a second sound wave receiving device.
In this scheme, first sound wave receiving equipment is carrying out speech communication's in-process with second sound wave receiving equipment, if receive two at least sound waves, can choose therefrom and treat the filtration sound wave, and directly filter and treat the filtration sound wave, give second sound wave receiving equipment with remaining sound wave transmission, when the environment that first sound wave receiving equipment located is very noisy, can reduce the interference to a great extent, thereby promote the speech communication quality, promote user experience, compare the mode of the processing of making an uproar that falls that adopts among the correlation technique, can fundamentally get rid of the sound wave of interference, guarantee the speech communication quality more effectively.
Specifically, the implementation process of detecting whether the at least two sound waves carry the first characteristic information in S11, as shown in fig. 3, specifically includes:
s111: at least two sound waves are respectively converted into electric signals.

S113: and determining that the sound wave corresponding to the electric signal carrying the first characteristic information carries the first characteristic information and the sound wave corresponding to the electric signal not carrying the first characteristic information does not carry the first characteristic information.
Because the first sound wave receiving device cannot directly process the sound waves, each sound wave needs to be converted into an electric signal, whether the sound wave carries the first characteristic information or not is detected based on the converted electric signal, if the electric signal carries the first characteristic information, it can be determined that the sound wave corresponding to the electric signal carries the first characteristic information, if the electric signal does not carry the first characteristic information, it can be determined that the sound wave corresponding to the electric signal does not carry the first characteristic information, and whether the sound wave carries the first characteristic information or not can be detected through S111-S113.
Specifically, there are many ways to select the sound wave to be filtered from the sound waves carrying the first characteristic information in S12, and two ways are described below.
The first mode, as shown in fig. 4, specifically includes:
s121: and displaying the carried first characteristic information for the sound wave carrying the first characteristic information.
S122: first feature information selected by a user is received.
S123: and acquiring the sound wave corresponding to the first characteristic information selected by the user to obtain the sound wave to be filtered.

In this way, a feature information set needs to be established in advance, and the establishment process specifically includes: establishing a communication connection with at least one surrounding sound wave generating device; and receiving second characteristic information sent by at least one sound wave generating device through the communication connection to obtain a characteristic information set.

When the first sound wave receiving device establishes a bluetooth communication connection with at least one sound wave generating device around, the first sound wave receiving device may first send a bluetooth search request, and if the at least one sound wave generating device around receives the bluetooth search request, the first sound wave receiving device may send a bluetooth search response in response to the first sound wave receiving device. After the first sound wave receiving device receives at least one Bluetooth search response, Bluetooth communication connection can be established between the first sound wave receiving device and the sound wave generating device which sends the Bluetooth search responses. The first sound wave receiving device can communicate with the sound wave generating device based on the bluetooth communication connection for transmission of characteristic information or the like.
