Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] In order to overcome the diffusion problem caused by sound transmission, parametric speakers, visual sensors and auricle recognition technologies are used in the present invention. The parametric array speakers, visual sensors and auricle recognition technologies are described below:

[0043] The basic principle of the parametric array loudspeaker is to modulate the audio signal and the ultrasonic carrier signal. Since the high-intensity ultrasonic carrier modulation signal produces a nonlinear effect when it propagates in the air, the audio signal is regenerated, and the strong di...

Abstract

The invention provides a sound oriented transmission method of a mobile terminal and the mobile terminal. The method comprises the steps of: storing auricle images of a user into the internal storage of the mobile terminal in advance; when the mobile terminal plays sound, starting an image obtaining device to obtain the front image of the mobile terminal; recognizing that whether auricle characteristics are included in the front image; if the auricle characteristics are recognized, matching the auricle characteristics in the auricle images stored in the mobile terminal with the auricle characteristics in the front image; if the matching is successful, obtaining relative three-dimensional space coordinates of the ears of the user relative to a parametric array loudspeaker in the mobile terminal, starting the parametric array loudspeaker, and transmitting sound signals towards the directions of the ears according to the obtained relative three-dimensional space coordinates. According to the sound oriented transmission method of the mobile terminal and the mobile terminal, after being recognized, the ears of the user are positioned, sound is transmitted in an oriented manner by the parametric array loudspeaker, and thereby sound diffusion is reduced, and interference of the sound on people nearby is avoided.

Description

technical field [0001] The present invention relates to the field of intelligent terminal equipment, in particular to a mobile terminal sound directional transmission method and the mobile terminal. Background technique [0002] With the popularization of mobile terminals, especially smart phones, they have become a necessity in users' lives. Making calls, listening to music, watching videos, and watching news through mobile terminals take up a lot of time for users. [0003] Due to the use of mobile terminals, it often happens outdoors. For example, when people go out, they often need to communicate with family or friends on the phone, or they are bored during the journey and want to listen to music or watch videos, but because they are in public places , When making a phone call, you don’t want to be heard by others when you have a private conversation, or when you are listening to music or watching a video, it may cause interference to others. Therefore, when the mobile t...
