For example, the first earpiece 210 may emit a sound toward a side of the electronic device 200 on which the display is displayed, the second earpiece 220 may emit a sound toward a peripheral direction of the electronic device, the first earpiece 210 may serve as a main earpiece of the electronic device 200, and the second earpiece 220 may serve as a secondary earpiece of the electronic device 200.

It is to be understood that the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.

The first earpiece 210 and the second earpiece 220 are spaced apart by less than a predetermined distance, such as the first earpiece 210 and the second earpiece 220 are spaced apart by less than 0.5 cm, 1 cm, 2 cm, 3 cm, and so on. In some embodiments, the first earpiece 210 and the second earpiece 220 may each be mounted at a location at the same end of the electronic device 200, such as mounting the first earpiece 210 and the second earpiece 220 each to a top end of a display of the electronic device 200.

The signal line may be understood as a conductive line, such as a copper line.

The memory 203 may be used for storing computer programs and data, such as for storing audio data. The memory 203 stores computer programs containing instructions executable in the central processor 270. The computer program may constitute various functional modules.

The central processor 270 is a control center of the electronic device 200, connects various parts of the whole electronic device 200 by using various interfaces and lines, and performs various functions of the electronic device 200 and processes data by running or calling a computer program stored in the central processor 270 and calling data stored in the central processor 270, thereby integrally monitoring the electronic device 200. Such as the central processing unit 270 controlling the display 230 of the electronic device 200 to display pictures, such as the central processing unit 270 controlling the first earpiece 210 of the electronic device 200 to emit sound signals.

The audio processor 280 is further electrically connected to the first earpiece 210 and the second earpiece 220, such as the audio processor 280 is connected to the first earpiece 210 through a copper wire, and the audio processor 280 is connected to the second earpiece 220 through a copper wire. The audio processor 280 may receive the audio signal emitted from the central processor 270, the audio processor 280 processes the audio signal received by the audio processor 280, such as converting, and the like, and the audio processor 280 transmits the processed audio signal to the first earpiece 210 and the second earpiece 220 to drive the first earpiece 210 and the second earpiece 220 to emit the sound signal. The audio processor 280 may be understood as an audio processing module or as a power amplifier module.

In practical applications, the electronic device 200 may generate audio signal leakage when talking on one or two earphones.

Based on this, the embodiment of the present application may drive the first earpiece 210 and the second earpiece 220 through the audio processor 280 to form an acoustic short circuit during the emission of the sound signal so as to attenuate the audio signal leaked from the electronic device 200.

Referring to fig. 2, fig. 2 is a second structural frame of an electronic device according to an embodiment of the present disclosure. The input 281 of the audio processor 280 is electrically connected to the central processor 270, such as through a copper wire.

Wherein the first phase and the second phase are opposite in direction. Two signals may also be generated in opposite phases such that the first earpiece 210 and the second earpiece 220 form an acoustic short circuit during the sound production to attenuate the audio signal. Particularly, the low frequency part of the audio signal is attenuated, so that the audio signal leaked toward the periphery by the electronic apparatus 200 can be effectively attenuated when the user is talking, thereby improving the talking performance.
