As shown in fig. 1 to 3, the mobile terminal may include:
a plurality of microphones for capturing ambient noise when the mobile terminal is in a predetermined state, wherein the predetermined state may include, but is not limited to, the following: the distance between the mobile terminal and the human ear is smaller than a threshold value (the threshold value can be preset and can be 5 cm for example); the mobile terminal is in a call mode and is not connected with an earphone;
the microcontroller is connected with at least one sound pickup and used for receiving the ambient noise sent by the sound pickup, determining offset noise according to the ambient noise and superposing the offset noise and the audio frequency of the mobile terminal, wherein the sound wave of the offset noise is opposite to the sound wave of the ambient noise;
at least one loudspeaker is connected with the microcontroller and is used for receiving the superposed audio frequency sent by the microcontroller and transmitting the superposed audio frequency to human ears, so that the superposed audio frequency can counteract the ambient noise in the superposed audio frequency in the process of transmitting the superposed audio frequency to the human ears.
Each device in this embodiment will be described in detail below.
Among them, as shown in fig. 2, the multiple sound pickup in the mobile terminal provided by the present application may include a top sound pickup 6 disposed at the top of the mobile terminal, a bottom sound pickup 3 disposed at the bottom of the mobile terminal, and a back sound pickup 5 disposed at the back of the mobile terminal. Wherein the top microphone 6 may for example be used to pick up sound from the top of the mobile terminal, the bottom microphone 3 may for example be used to pick up sound from the bottom of the mobile terminal, and the back microphone 5 may for example pick up sound from the back of the mobile terminal.
It should be noted that, in this embodiment, the back sound pickup 5 may be specifically disposed at a camera on the back of the mobile terminal, so that when the user holds the mobile terminal by hand, the back sound pickup can be prevented from being shielded to affect the sound pickup effect.
Furthermore, a sound pick-up device can be arranged on the side edge of the mobile terminal, so that the sound acquired by the mobile terminal is more comprehensive.
In addition, it should be noted that, when the user holds the mobile terminal, it is inevitable to block part of the sound pickup (for example, the sound pickup disposed at the side of the mobile terminal may be blocked), and thus, in this embodiment, when the mobile terminal is in a predetermined state and the sound pickup is required to acquire the ambient noise, only the sound pickup that is not blocked may be activated to acquire the ambient noise, and the blocked sound pickup may not be activated to acquire the ambient noise, so that the sound pickup effect of the sound pickup may be ensured, and the ambient noise may be accurately acquired.
And, referring to fig. 2, the at least one speaker in the mobile terminal of the present embodiment may include a top speaker 1 disposed at the top of the mobile terminal, a bottom speaker 4 disposed at the bottom of the mobile terminal, and a screen sounder 2.
The method for transmitting the superimposed audio to the human ear by using at least one speaker may include the following two methods:
the method comprises the following steps: the audio of the mobile terminal is transmitted by a first part of the at least one loudspeaker, and the cancellation noise is transmitted by a second part of the at least one loudspeaker. Wherein the first part of loudspeakers and the second part of loudspeakers each comprise at least one loudspeaker.
For example, the top speaker 1 and the screen sounder 2 in fig. 1 may be used to transmit audio of the mobile terminal, and the bottom speaker 4 may be used to transmit canceling noise.
The second method comprises the following steps: at least one speaker is used to simultaneously transmit the audio frequency of the mobile terminal and cancel the noise.

In addition, it should be noted that, in this embodiment, whether the first method or the second method is adopted mainly depends on the corresponding cancellation effect of the two methods. If the cancellation effect corresponding to the first method is better (namely, when the superimposed audio is transmitted by the first method, the ambient noise can be better cancelled, and the audio played by the mobile terminal is clearer), the superimposed audio is transmitted by the first method; and if the cancellation effect corresponding to the second method is better, transmitting the superposed audio by adopting the second method.
Then, in conjunction with the above and with reference to fig. 2, ambient noise 7 may be acquired by top microphone 6, bottom microphone 3, and back microphone 5, and the microcontroller may process and analyze ambient noise 7 to determine the acoustic wave from ambient noise 7 as the opposite cancellation noise of the acoustic wave from the ambient noise (i.e., -ambient noise), and superimpose the cancellation noise with the audio output by the mobile terminal, and then output the superimposed audio 8 (i.e., -ambient noise + audio played by the mobile terminal). Wherein the superimposed audio 8 is output jointly by the top loudspeaker 1, the bottom loudspeaker 4 and the screen generator 2. And after the superimposed audio 8 is output, the cancellation noise therein and the ambient noise 7 cancel each other to obtain the audio 9 input to the human ear (i.e., -ambient noise + audio played by the mobile terminal + ambient noise).
Therefore, in the embodiment of the present disclosure, when the mobile terminal plays the audio, the cancellation noise opposite to the ambient noise sound wave is superimposed to play, so that the sound received by the human ear is changed from "ambient noise + the audio played by the mobile terminal" to "ambient noise + the audio played by the mobile terminal-ambient noise = the audio played by the mobile terminal", so that the sound finally reaching the human ear is an audio that is infinitely close to the audio played by the mobile terminal, and then the noise reduction processing on the played audio is implemented.
Further, as shown in fig. 3, the mobile terminal provided by the present application may further include a network module, which may be connected to the microcontroller, and is used to enable the mobile terminal to establish a connection (e.g., a data or voice connection) with the network. And, the mobile terminal may further include a power circuit, which may be used to power the mobile terminal.
