As shown in fig. 1, an embodiment of the invention provides a schematic diagram of an audio electrical signal conversion assembly. The audio electric signal conversion component 1 includes at least a decoder (codec)11, a receiver 12, and an exciter 13. The decoder 11 is connected to the receiver 12, and the decoder 11 is connected to the exciter 13.

Note that since the frequency characteristics expressed by the receiver 12 and the exciter 13 are different, the same audio parameters cannot be used. It is necessary to provide 2 sets of processing paths, one path of which separately processes the audio electrical signal entering receiver 12, and the other path of which specially processes the audio electrical signal entering exciter 13.
For example, the decoder 11 further divides the decoded audio electrical signal into two audio electrical signals, which may be identical audio electrical signals. For example, the frequency response and gain of the two audio electrical signals may be the same. Then, the decoder 11 may process the frequency response and the gain of each of the two audio electrical signals to obtain a first audio electrical signal and a second audio electrical signal. Wherein the first electrical audio signal has a first frequency response and a first gain and the second electrical audio signal has a second frequency response and a second gain.

The coil of the linear motor 131 is fixed to the case of the linear motor 131, and then the vibrator movement inside generates vibration. When the vibration frequency of the linear motor 131 is in the range of the human auditory frequency and the vibration intensity of the linear motor 131 is large, it can be recognized as a sound signal by the human ear.
Optionally, the device further comprises a driver; the driver is connected with the decoder 11, and the driver is connected with the linear motor;
the driver amplifies the second audio electric signal;
the linear motor converts the amplified second audio electric signal into the second voice signal.
The audio electrical signal conversion assembly 1 may further comprise a driver 14. The driver 14 is connected to the decoder 11, and the driver 14 is connected to the linear motor 131. Fig. 2 is a schematic diagram of another audio electrical signal conversion assembly.

Thus, the first audio electric signal is converted into a first voice signal through the telephone receiver; the second audio electrical signal is converted to a second speech signal by the exciter. Namely, the volume during the call can be increased by assisting the sounding through the exciter. The telephone receiver does not need to be used in an over-power mode, the telephone receiver can be prevented from being burnt, and stability and safety can be improved.
The embodiment of the invention also provides a terminal which comprises the audio electric signal conversion component 1.
Optionally, the terminal further comprises foam;

The terminal may also comprise a foam and the actuator 13 is connected to the middle frame of the terminal. For example, the exciter 13 may be bonded to the center frame of the terminal. The foam has a first side connected to the actuator 13, for example, the foam may be glued to the actuator 13. The second side of the foam abuts the rear shell of the terminal.

When the linear motor 131 vibrates, the corresponding vibration is transmitted to the whole machine through the middle frame. When the ears of a person are close to the screen of the terminal, the corresponding vibration can be sensed. This process utilizes the principle of bone conduction, i.e., sound can be transmitted to the auditory nerve through the jaw and skull, causing hearing. It should be noted that since the linear motor 131 transmits sound by vibration, it is necessary for the human ear to be closely attached to the screen of the terminal. It is not perceptible if the human ear is not in close proximity to the screen of the terminal. The receiver 12 transmits the sound signal through air and the exciter 13 transmits the sound signal through solid vibration.

In step 402, since the frequency characteristics of the receiver 12 and the exciter 13 are different, the same audio parameters cannot be used. It is necessary to provide 2 sets of processing paths, one path of which separately processes the audio electrical signal entering receiver 12, and the other path of which specially processes the audio electrical signal entering exciter 13.
For example, the decoder 11 further divides the decoded audio electrical signal into two audio electrical signals, which may be identical audio electrical signals. For example, the frequency response and gain of the two audio electrical signals may be the same. Then, the decoder 11 may process the frequency response and the gain of each of the two audio electrical signals to obtain a first audio electrical signal and a second audio electrical signal.

When the exciter 13 vibrates, the corresponding vibration is transmitted to the whole machine through the middle frame. When the ears of a person are close to the screen of the terminal, the corresponding vibration can be sensed.
Note that sound propagates through vibration, and the greater the distance, the greater the attenuation. Therefore, the exciter 13 should be placed close to the upper portion of the terminal. At this time, the vibration source is closer to the human ear, and the loudness of sound felt by the human ear is larger. The exciter 13 needs to be closely coupled to the middle frame of the terminal in order for the vibration to be propagated.

The exciter 13 may be a linear motor 131. The linear motor 131 may be controlled to generate vibration to convert the second audio electric signal into a second voice signal. The coil of the linear motor 131 is fixed to the case of the linear motor 131, and then the vibrator movement inside generates vibration. When the vibration frequency of the linear motor 131 is in the range of the human auditory frequency and the vibration intensity of the linear motor 131 is large, it can be recognized as a sound signal by the human ear.
The linear motor 131 may be adhered to the middle frame of the terminal, and the linear motor 131 generates vibration according to the second audio signal. When the linear motor 131 vibrates, the corresponding vibration is transmitted to the whole machine through the middle frame. When the ears of a person are close to the screen of the terminal, the corresponding vibration can be sensed. This process utilizes the principle of bone conduction, i.e., sound can be transmitted to the auditory nerve through the jaw and skull, causing hearing. It should be noted that since the linear motor 131 transmits sound by vibration, it is necessary for the human ear to be closely attached to the screen of the terminal. It is not perceptible if the human ear is not in close proximity to the screen of the terminal. The linear motor 131 has a large vibration amount, and a large-sized linear motor needs to be selected.

The driver 14 performs an amplification process on the second audio electric signal having the second frequency response and the second gain. The linear motor 131 may be controlled to generate vibration to convert the second audio electric signal, which is amplified by the driver 14, into a second voice signal. And amplifying the second audio electric signal by using a driver, and outputting the amplified second audio electric signal to the linear motor. In this way, the loudness of the speech signal converted by the linear motor is greater.

That is, the receiver 12 projects at a medium-high frequency, and the exciter 13 projects at a medium-low frequency.
Optionally, the converting the first audio electrical signal into a first voice signal by the receiver includes:
under the condition that an object is detected to contact the screen of the terminal, converting the first audio electric signal into the first voice signal through the telephone receiver;
in case it is detected that no object touches the screen of the terminal, the method further comprises:
and converting the decoded audio electric signal into a third voice signal through the telephone receiver.
When a user uses the terminal to make a call, the decoded audio electric signal may be converted into a speech signal only by using the receiver 12. The receiver 12 and the exciter 13 may be used simultaneously. At this time, the receiver 12 and the exciter 13 work synchronously, and the voice signal converted by the microphone 12 and the voice signal converted by the exciter 13 are superposed together, so that the loudness of the voice signal sensed by the user is large, namely, the volume during the call is increased.
For example, the terminal may detect whether an object touches a screen of the terminal. In case that it is detected that an object touches the screen of the terminal, the first audio electric signal may be converted into a first voice signal through the receiver 12, and the second audio electric signal may be converted into a second voice signal through the exciter 13. In the case where it is detected that no object touches the screen of the terminal, the decoded audio electric signal may be converted into the third voice signal only by the receiver 12. This is because the exciter 13 is vibration-borne and is not felt if the human ear is not pressed against the screen. Therefore, when an object touching the screen of the terminal is detected, the exciter 13 is triggered to vibrate for volume compensation.
Optionally, the converting, by the receiver, the first audio electrical signal into the first voice signal when it is detected that an object touches a screen of the terminal includes:

and converting the decoded audio electric signal into a fourth voice signal through the telephone receiver.
Further, the user can decide whether to use only the receiver 12 or to use both the receiver 12 and the exciter 13 as desired. For example, when the user wants to use the receiver 12 and the exciter 13 simultaneously, the call volume of the terminal can be manually adjusted to be greater than or equal to the preset volume threshold. For example, the call volume of the terminal may be adjusted to the maximum volume. The terminal can detect the current call volume and can also detect whether an object contacts the screen of the terminal. When the call volume of the terminal is greater than or equal to the preset volume threshold and an object is detected to contact the screen of the terminal, the first audio electric signal can be converted into the first voice signal through the telephone receiver, and the second audio electric signal can be converted into the second voice signal through the exciter 13. In the case that the call volume of the terminal is less than the preset volume threshold, the decoded audio electric signal may be converted into the fourth voice signal only by the receiver 12. In this way, the user can decide whether to use only the receiver 12 or to use both the receiver 12 and the exciter 13 as desired. And the operation process is simple, convenient and fast. In the case where the receiver 12 and the exciter 13 operate synchronously, the voice signal converted by the microphone 12 and the voice signal converted by the exciter 13 are superposed together, so that the loudness of the voice signal perceived by the user is large, i.e., the volume of the voice signal during conversation is increased.
According to the audio electrical signal conversion method provided by the embodiment of the invention, a user can decide whether to use only the receiver 12 or simultaneously use the receiver 12 and the exciter 13 according to the needs of the user. And the operation process is simple, convenient and fast. Under the condition that the receiver 12 and the exciter 13 work synchronously, the first audio electric signal is converted into a first voice signal through the receiver; the second audio electrical signal is converted to a second speech signal by the exciter. Namely, the volume during the call can be increased by assisting the sounding through the exciter. The telephone receiver does not need to be used in an over-power mode, the telephone receiver can be prevented from being burnt, and stability and safety can be improved. Since the receiver and the exciter are standard components of the terminal, no additional hardware is required, i.e. no cost is added to the hardware. Compared with the prior art, the method does not need to sharpen the sound in the large volume mode, so that the listening feeling is better during the call, and the feeling of harsh and uncomfortable feeling can not occur.
