The invention discloses a sound playing method, a sound receiving method and an electronic device, belongs to the technical field of electronics, and aims to solve the problem that in a sound directional propagation scene, the propagation direction is fixed, and if the direction of a receiver receiving sound relative to the electronic device is changed, the receiver cannot receive a sound signal.The sound playing method comprises the following steps: playing a first sound signal according to a first target azimuth parameter; receiving an instruction fed back by the sound receiving device based on the first sound signal; under the condition that the instruction indicates that the first sound signal meets the preset condition, playing a second sound signal according to the first target azimuth parameter; under the condition that the instruction indicates that the first sound signal does not meet the preset condition, updating to a second target azimuth parameter; wherein the first soundsignal is used for being received by a sound receiving device, and the second sound signal is used for being received by a user corresponding to the sound receiving device. The sound playing method is applied to the electronic device.
Description
technical field [0001] The present application belongs to the field of electronic technology, and in particular relates to a sound playing method, a sound receiving method and electronic equipment. Background technique [0002] Speakers in electronic equipment are used to play sound signals in electronic equipment. The sound signal played by ordinary speakers can be transmitted 360° in the air. With people's demand for directional sound transmission, ultrasonic speakers appeared. The working principle of the ultrasonic speaker is: the audible sound signal is modulated onto the ultrasonic carrier signal and emitted into the air by the ultrasonic transducer. During the propagation of ultrasonic waves of different frequencies in the air, due to the nonlinear acoustic effect of air, these signals will interact and self-demodulate, resulting in a frequency that is the difference between the sum of the original ultrasonic frequencies (sum frequency) and the frequency (difference...
