Directional sounding method and device, ultrasonic transducer and electronic equipment

Abstract

The invention provides a directional sound production method and device, an ultrasonic transducer and electronic equipment. The directional sound production method is applied to the electronic equipment, the electronic equipment comprises an ultrasonic transducer, first position information of a user before displacement and second position information of the user after displacement are acquired firstly, and an ultrasonic propagation path emitted by the ultrasonic transducer covers a first position; a rotation angle of the ultrasonic transducer is determined according to the first position information, the second position information and the position of the ultrasonic transducer; and the super-energy transducer is controlled to rotate according to the rotation angle, so that the propagationpath of the ultrasonic waves emitted by the rotated ultrasonic transducer covers the second position. According to the technical scheme, a dynamic and real-time directional sound production effect can be achieved, so that the user does not interfere with others in the same space while protecting personal privacy or working confidentiality, and noise interference of collective work and life is reduced to a great extent.

Description

technical field [0001] The invention relates to the field of audio technology, in particular to a directional sound generation method, device, ultrasonic transducer and electronic equipment. Background technique [0002] Directional sound technology, as the name suggests, is that the sound is no longer 360-degree diffuse sound like traditional speakers, but is directional and transmits sound along a certain path. This technology can lock the noise of square dancing and campus broadcasting in a specific area and solve the problem of disturbing people. It can also be used in museums to explain exhibits and supermarkets to explain products, broadening the way exhibits and product information are communicated, and will not cause sound pollution. [0003] In modern life, mobile phones have become an inseparable part. According to the "China Mobile Internet 2018 Semi-annual Report" released by QuestMobile last year, Chinese mobile Internet users are increasingly dependent on the ...

Problems solved by technology

[0004] However, the existing directional sound emitting devices can only emit sound in a specific direction. When the position information of the user relative to the electronic device changes, it may face the problem of leaving the directional sound emitting area and being unable to receive directional sound waves.
