Abstract

The invention discloses electronic equipment, which comprises an equipment main body, a first sound production device and a second sound production device, the first sound production device and the second sound production device are both arranged in the equipment main body, the first sound production device emits first ultrasonic waves, the second sound production device emits second ultrasonic waves, and the frequency of the first ultrasonic waves is different from that of the second ultrasonic waves; a first sound guide channel and a second sound guide channel are arranged in the equipment main body, a first sound guide hole and a second sound guide hole are formed in the outer surface of the equipment main body, and the first sound production device is communicated with the first sound guide hole through the first sound guide channel; and the second sound production device is communicated with the second sound guide hole through the second sound guide channel. According to the scheme, the problem that sound emitted by the electronic equipment cannot be directionally transmitted can be solved.

Description

technical field [0001] The invention relates to the field of audio technology, in particular to an electronic device. Background technique [0002] With the rapid development of electronic equipment, the application of electronic equipment is becoming more and more extensive. Electronic equipment such as mobile phones and tablet computers play more and more roles in people's work, life, and entertainment. [0003] At present, the speakers and receivers of electronic equipment amplify the audio signal and push the air through the sound film to make sound. The frequency range of human audible sound is 20Hz-20kHz, because the sound wave of audible sound does not have obvious directivity when propagating in the air. , causing the sound to spread in all directions around, which in turn causes the sound to be heard by more people. When people use electronic devices to play music, watch videos or video chat, they are easy to influence others. Therefore, people are eager for electr...
