Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
One of the core ideas of the embodiment of the application is that when a mobile terminal carries out group call, voice signals in the group call are subjected to howling suppression processing, and then the voice subjected to the howling suppression processing is played through a receiver; and the voice collected by the receiver is filtered.
Referring to fig. 1, a flowchart illustrating steps of embodiment 1 of a communication method of a mobile terminal according to the present application is shown, which may specifically include the following steps:
in the embodiment of the application, the specific program is an online game program, and the specific group is an online game group. When a user runs a network game on a mobile terminal and carries out group voice communication with other players, because the conversation sequence in the group voice can be synchronous, a plurality of users can speak at the same time to generate a plurality of voice signals and the background sound of the game; if the receiver of the mobile terminal plays such a plurality of voice signals at the same time, when the plurality of voice signals have signals with the same frequency, the phenomenon of 'same frequency resonance' can be generated. The "same-frequency resonance" means that when one sound wave meets another sound wave with the same frequency, stronger sound wave oscillation is emitted, but when the sound wave meets the sound waves with different frequencies, the oscillation generated by the sound signals with the same frequency is amplified and gained by the microphone, and howling is easily generated. It is therefore necessary to perform howling suppression processing on the voice signals before the plurality of voice signals are played by the handset.
and playing the voice signal subjected to the howling suppression processing through the receiver.
the microphone simultaneously collects the voice signal of the front user and the feedback signal generated by the voice signal played by the receiver. After the voice signals of other users and the voice signals of the game played by the receiver are reflected by the surrounding environment, part of the voice signals are reflected back to the microphone of the mobile terminal. In this case, the partially reflected signal corresponds to noise. It is therefore desirable to filter out this portion of the reflected signal.
Another reason for the howling is that the microphone converts the sound signal into an electrical signal, which may directly reach the receiver, which converts the electrical signal into a sound signal, which is then picked up by the microphone, thus creating a positive feedback between the microphone and the receiver. After continuous positive feedback, the noise will cause howling. Therefore, a filtering process is required for the voice signal collected by the microphone.
104, filtering the voice signal collected by the microphone;
and filtering other signals except the voice signal of the current user in the voice signals.
And 105, sending the voice signal after the filtering processing to other users in the group.
And sending the filtered voice signals to other users in the group, wherein the filtered voice signals mainly comprise the voice signals of the current user and have no other noise signals, so that the noise received by other users can be reduced.
Referring to fig. 2, a flowchart of steps of embodiment 2 of a communication method of a mobile terminal according to the present application is shown, which may specifically include the following steps:
when the mobile terminal runs a specific program process and runs a specific group call program to perform a group call, the frequency of the voice signal of each other user is identified, and the frequency of the sound signal of the specific program process, such as the frequency of the sound signal of a game program.
when the signal frequency of the voice signal of other users is the same as the signal frequency of the sound signal of the specific program process, an oscillation signal is generated, the oscillation signal is amplified by a microphone, and when the gain is too large, howling is generated. It is therefore necessary to reduce the signal gain of the voice signal of the specific program process and the signal gain of the voice signal of the specific program process in the voice signals of other users at the same frequency as the signal frequency of the voice signal of the specific program process.
In a preferred example of the embodiment of the present application, the method may further include the following steps:
when the voice signals of other users have signals with the same signal frequency, an oscillation signal is generated, the oscillation signal is amplified by a microphone, and when the gain is too large, howling is generated. It is therefore necessary to reduce the signal gain for the same signal frequency.
Referring to fig. 3, a flowchart of steps of embodiment 3 of a communication method of a mobile terminal according to the present application is shown, which may specifically include the following steps:
when the mobile terminal runs a specific program process and runs a specific group call program to perform a group call, the frequency of the voice signal of each other user is identified, and the frequency of the sound signal of the specific program process, such as the frequency of the sound signal of a game program.
when the signal frequency of the voice signal of other users is the same as the signal frequency of the sound signal of the specific program process, an oscillation signal is generated, the oscillation signal is amplified by a microphone, and when the gain is too large, howling is generated. Therefore, it is necessary to adjust the frequencies of two signals having the same frequency to avoid oscillation, and to avoid adjusting the sound signal of the game program as much as possible and to perform frequency shift processing only on the signal having the same frequency as the sound signal of the progress of the game program among the sound signals of other users in order to obtain a better game experience for the users.
In a preferred example of the embodiment of the present application, the method may further include the following steps:
and performing frequency shift processing on one of the signals with the same signal frequency in the voice signals of other users to avoid oscillation.
Referring to fig. 4, a flowchart of steps of embodiment 4 of a communication method of a mobile terminal of the present application is shown, which may specifically include the following steps:
the feedback signal comprises a feedback signal generated by voice signals of other users and sound signals of the specific program process.
For each user in the communication group, the heard speech includes: the sound signal of the game program is mostly the same as the sound signal of the other users, and the sound signal of the game program is basically the same as the sound signal of the other users, except that there is no own sound signal. Therefore, when the frequency of the voice signal of the current user is the same as the frequency of the signal received by the mobile terminal of the current user from the feedback signal, it can be considered that one of the feedback signals received by the mobile terminals of other users is the same as the frequency of the voice signal of the current user, that is, for other users, frequency oscillation may occur as long as the voice signal of the current user is received. Therefore, the frequency shift processing can be carried out on the voice signal of the current user, and the mobile terminals of other users are prevented from generating howling;
in addition, the feedback signal of the current user can be regarded as noise to other users, and therefore, the feedback signal needs to be filtered.
when the frequency of the current user voice signal is different from the included signal frequency of the feedback signal, the signal frequency included in the feedback signal is directly filtered.
