Technical field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a terminal for a voice call.

Background technique

With the development of communication technology, users have higher and higher requirements for the quality of calls during a call. In the actual call process, in addition to the network, signal, terminal quality and other objective factors will affect the call quality, the environmental noise of the environment in which the terminal is located also has a great impact on the call quality. At present, most of the earpieces used in the terminal work in such a way that sound waves generated by diaphragm vibration are transmitted to the user through air vibration. Due to the air involved in the transmission of sound, if the noise of the environment in which the terminal is located is too large, noise may be masked to cover the sound played by the terminal earpiece, so that the user cannot hear the other party's speech during the call.

At present, if the user cannot hear the speech content of the other party during the call, the software in the terminal is triggered to adjust the filter by increasing the volume, thereby increasing the volume of the sound played by the terminal handset, thereby enabling the user to listen. Clear the other party's speech. However, excessive volume can reduce the life of the earpiece and cause damage to the user's hearing system.

detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, instead of All embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The embodiment of the present invention can be used for a terminal, which can detect the noise of the environment in which the terminal is currently located, and obtain the corresponding processing result by analyzing the noise data, and then determine whether the handset needs to be switched according to the obtained processing result.

As shown in FIG. 1 , an embodiment of the present invention provides a terminal, which is provided with a main microphone 11 , a secondary microphone 12 , a moving coil type earpiece 13 , and a bone conduction type earpiece 14 . The main microphone 11 is disposed on the lower side of the terminal, and is mainly used for normal conversation; the auxiliary microphone 12 is disposed on the upper side of the terminal, and is mainly used for monitoring noise; the moving coil type earpiece 13 and the bone conduction type earpiece 14 are both disposed at the terminal. Above the screen, a voice signal is played, and the sound hole of the moving coil type earpiece 13 is adjacent to the vibration area of the bone conduction type earpiece 14. It should be noted that each component in the terminal may have other installation modes, and the installation mode is not limited in the present invention.

The embodiment of the invention provides a method for voice call, which can be applied to the terminal shown in FIG. 1 . As shown in FIG. 2, the method process specifically includes:

101. Detecting noise of the current environment of the terminal.

102. If the noise is greater than the noise threshold, the osteoconductive earpiece is activated.

The noise threshold is used to indicate the amount of noise that the user can receive when using the terminal to make a call. In general, the noise intensity in a quiet environment can be used as a noise threshold, or the noise threshold can be set empirically, or after setting, a limited number of adjustment tests can be used to obtain an appropriate value.

The bone conduction type of the earpiece uses bone conduction to transmit sound waves. First, the sound is converted into mechanical vibration of different frequencies, and then transmitted through the human skull, the bone labyrinth, the inner ear lymph, the spiral, the auditory nerve, and the auditory center. The step of transmitting sound waves in the air enables clear sound reproduction in a noisy environment. Therefore, when the noise of the current environment of the terminal is greater than the noise threshold, A bone conduction earpiece can be used to play a voice signal to improve the quality of the user's call.

It should be noted that a trigger can be set on the terminal. When detecting that the noise of the current environment of the terminal is greater than the noise threshold, the terminal can automatically trigger the terminal to start the bone conduction type earpiece; and a bone conduction type earpiece can also be set on the terminal. The switch can manually activate the bone conduction earpiece when the user feels that the noise is too large to hear the other party's speech.

103. Playing a voice signal through a bone conduction type earpiece.

In the embodiment of the present invention, the bone conduction type earpiece may be a piezoelectric ceramic piece, and the bone conduction type earpiece may be disposed in the terminal in a manner of sticking the piezoelectric ceramic piece to a specific area above the screen. In this case, when the terminal receives the voice signal, the piezoelectric ceramic piece driven by the voice signal generates deformation to promote the vibration of the pasting area, and then the voice signal is transmitted to the user through the human skeleton. Since the driving voltage required for the deformation of the piezoelectric ceramic piece is high, it is also possible to add an amplification module before the bone conduction type earpiece to ensure that the piezoelectric ceramic piece can be driven.

As shown in FIG. 3, an embodiment of the present invention provides a circuit connection diagram between components in a terminal. An amplifier 15 is disposed in the terminal, and an input end of the amplifier 15 is connected to the CODEC (English: COderDECoder, Chinese: codec) At the output of 16 , the output of amplifier 15 is connected to bone conduction earpiece 14. At this time, the signal output from the CODEC 16 is amplified by the amplifier to drive the piezoelectric ceramic piece of the bone conduction type earpiece to vibrate.

A method for voice call provided by an embodiment of the present invention, if it is detected that the noise of the current environment of the terminal is greater than a noise threshold, the bone conduction type earpiece is activated to play the voice signal. Compared with the prior art method of increasing the volume to improve the quality of the call, the present invention can determine the manner in which the voice signal is played according to the size of the noise. Since the bone conduction type earpiece uses bone conduction to transmit sound waves, the process of transmitting sound waves in the air is omitted, and therefore, the voice signal is played through the bone conduction type earpiece. Achieve clear sound reproduction without increasing the volume, thereby avoiding damage to the earpiece and the user's hearing system while improving the quality of the call. Therefore, the present invention can improve the quality of a voice call without the earpiece and the user's hearing system being damaged.

In an implementation manner of the embodiment of the present invention, an earpiece for playing a voice signal may be switched when the noise satisfies a certain condition. Therefore, on the basis of the implementation shown in FIG. 2, an implementation as shown in FIG. 4 can also be implemented. If the noise is greater than the noise threshold in step 102, the bone conduction type earpiece is activated, which may be specifically implemented as step 1021:

1011. If the noise is greater than the noise threshold, the handset that plays the voice signal is switched from the moving coil handset to the bone conduction earpiece.

When it is detected that the noise of the current environment of the terminal is greater than the noise threshold, in order to avoid noise interference with normal conversation, the earpiece that plays the voice signal can be switched from the dynamic coil that is susceptible to environmental noise to the bone conduction that is not easily interfered by environmental noise. Earpiece.

It should be noted that in order to avoid the confusing sound, during the voice call, the moving ring type earpiece and the bone conduction type earpiece are generally not used simultaneously to play the voice signal, that is, after the bone conduction type earpiece is activated, the moving ring type earpiece must be stop working. In the embodiment of the present invention, the switching of the earpiece can be realized by setting a switch in the terminal. As shown in FIG. 3, the terminal is further provided with an analog switch 17, which can be a single-pole double-throw switch. The input end of the analog switch 17 is connected to the output end of the CODEC16, and the two output ends of the analog switch 17 are respectively connected. The loop earpiece 13 and the bone conduction earpiece 14. If the terminal determines that the noise is greater than the noise threshold, the output of the trigger analog switch 17 is switched by the moving coil type earpiece 13 to the bone conduction type earpiece 14, i.e., the circuit of the moving coil type earpiece 13 is turned off, and the circuit of the bone conduction type earpiece 14 is turned on.

A method for voice call provided by an embodiment of the present invention, if it is detected that the noise of the environment in which the terminal is currently located is greater than a noise threshold, the handset that plays the voice signal is switched from the moving coil type to the bone conduction type. earpiece. Compared with the prior art method for increasing the volume by increasing the volume, the present invention can switch the handset according to the magnitude of the noise, and when the noise exceeds the noise threshold, the handset is disturbed by noise. The loop type earpiece is switched to a bone conduction type earpiece that is not easily disturbed, so that the voice information can be directly transmitted to the user without air, so that the user can hear the other party's speech content and improve the quality of the voice call.

In an implementation manner of the embodiment of the present invention, when the noise is small, the voice signal can be played through the moving coil type handset. Therefore, on the basis of the implementation shown in FIG. 2, an implementation as shown in FIG. 5 can also be implemented. After performing step 101 to detect the noise of the current environment of the terminal, step 104 may also be performed:

104. If the noise is less than or equal to the noise threshold, the voice signal is played through the moving coil handset.

Since the human skull automatically attenuates the low frequency signal, signal distortion may occur when the bone conduction type is used for talking, and the signal distortion of the moving coil type is extremely small. At the same time, considering that the driving voltage of the bone conduction type earpiece is relatively high, the energy consumption is large when the voice signal is played through the bone conduction type earpiece. Therefore, in order to reduce distortion and reduce power consumption, the terminal can play a voice signal through a moving coil earpiece by default.

During the voice call, the terminal can periodically detect the noise of the current environment according to a certain time interval. If the detected noise is less than or equal to the noise threshold, the voice signal can be played through the moving coil. If the earpiece that currently plays the voice signal is a bone conduction type earpiece, the earpiece that plays the voice signal can be switched from the bone conduction earpiece to the moving coil type earpiece.

The method for voice call provided by the embodiment of the present invention, if the noise of the current environment of the terminal is detected to be less than or equal to the noise threshold, the voice signal is played through the moving coil. Compared with the prior art method of increasing the volume to improve the quality of the call, the present invention can determine the playing mode of the voice signal according to the size of the noise. Because of the good fidelity performance and high degree of reduction of the moving coil type earpiece. Therefore, When the noise is small, playing the voice signal through the moving coil type of handset can not only make the user hear the other party's speech content, but also can truly restore the other party's speech content and improve the communication quality.

In an implementation manner of the embodiment of the present invention, a dual microphone may be set to determine the ambient noise according to the voice signals received by the two microphones. Therefore, on the basis of the implementation shown in FIG. 2, an implementation as shown in FIG. 6 can also be implemented. The terminal is further configured with a primary microphone and a secondary microphone. Step 101 detects the noise of the environment in which the terminal is currently located, and may be specifically implemented as step 1011 to step 1013. After performing step 1011, step 1014 may also be performed:

1011. Detect the strength of the voice signal received by the primary microphone and the secondary microphone, respectively.

In the embodiment of the present invention, since the main microphone is disposed on the lower side of the terminal and is relatively close to the pronunciation part of the user during the call, the received signal is mainly the user's voice; and the auxiliary microphone is disposed on the upper side of the terminal. It is relatively far away from the user's pronunciation part during the call. Therefore, the signal received by the secondary microphone is mainly noise. Ideally, the voice signal received by the primary microphone is a human voice with ambient noise, and the voice signal received by the secondary microphone includes only ambient noise, and the ambient noise characteristics received by the primary and secondary microphones are consistent.

1012. Determine a difference in intensity of a voice signal of the same content received by the primary microphone and the secondary microphone.

Considering that in the actual environment, there is no guarantee that the voice signal received by the secondary microphone includes only ambient noise, and usually the secondary microphone also receives the human voice. The vocal received by the secondary microphone is about 6 dB smaller than the vocal received by the primary microphone. Therefore, it is necessary to determine whether the voice signal received by the secondary microphone is noise according to the difference of the strengths of the voice signals received by the primary and secondary microphones.

1013. If the intensity difference is greater than the intensity threshold, determine the voice signal of the same content received by the secondary microphone as noise.

The intensity threshold is used to determine whether most of the voice signals received by the secondary microphone are noise signals, and the intensity threshold may be set by a person skilled in the art according to experience.

If the intensity difference is greater than the intensity threshold, it indicates that most of the voice signals of the same content received by the secondary microphone are noise signals, and the voice signal of the same content received by the secondary microphone can be determined as noise.

1014. If the voice signal is not detected by the primary microphone, and the secondary microphone detects the voice signal, the voice signal detected by the secondary microphone is determined to be noise.

If only the secondary microphone detects the voice signal, indicating that the user does not speak at this time, the signal detected by the secondary microphone includes only ambient noise, and the voice signal detected by the secondary microphone can be determined as noise.

The method for voice call provided by the embodiment of the present invention can be received by the secondary microphone if the strength of the voice signal of the same content received by the primary and secondary microphones is greater than a certain threshold, or only the secondary microphone receives the voice signal. The incoming speech signal serves as the noise of the environment in which the terminal is currently located. Compared with the method of increasing the volume in the prior art to improve the call quality, the present invention can determine whether the voice signal received by the secondary microphone is mainly based on the strength of the voice signal of the same content received by the primary microphone and the secondary microphone. For noise. Since the auxiliary microphone is disposed at a position away from the utterance portion of the user in the terminal, if the difference between the strengths of the voice signals received by the primary microphone and the secondary microphone is large, or only the secondary microphone detects the voice signal, the voice received by the secondary microphone is indicated. The signal is mainly noise, and therefore, the voice signal received by the secondary microphone can be determined as noise.

In an implementation manner of the embodiment of the present invention, the playing module 203 is further configured to play a voice signal through the moving coil type if the noise detected by the detecting module 201 is less than or equal to the noise threshold.

In an implementation manner of the embodiment of the present invention, the terminal is further configured with a primary microphone and a secondary microphone, and the detecting module is specifically configured to separately detect the strength of the voice signal received by the primary microphone and the secondary microphone;

Determining a difference in intensity of a voice signal of the same content received by the primary microphone and the secondary microphone;

If the intensity difference is greater than the intensity threshold, determining the voice signal of the same content received by the secondary microphone as noise;

If the voice signal is not detected by the primary microphone and the voice signal is detected by the secondary microphone, the voice signal detected by the secondary microphone is determined to be noise.

The device for voice call provided by the embodiment of the present invention starts the bone conduction type to play the voice signal if it is detected that the noise of the current environment of the terminal is greater than the noise threshold. Compared with the prior art method of increasing the volume to improve the quality of the call, the present invention can determine the manner in which the voice signal is played according to the size of the noise. Since the bone conduction type earpiece uses bone conduction to transmit sound waves, The process of transmitting sound waves in the air is eliminated, so that the voice signal can be played through the bone conduction type earpiece, and a clear sound reproduction can be realized without increasing the volume, thereby avoiding the earpiece and the user when improving the call quality.
