Problems solved by technology

[0012] Intelligent switching between speakers and earpieces, confidentiality and clarity cannot be unified
In addition, when the surrounding noise is too loud, the earpiece will also have the problem of unclear sound due to its insufficient maximum volume.
[0013] Therefore, the existing implementation has not yet provided a solution for effectively locating the user's position and accurately transmitting the sound to the area where the user is located.

Embodiment 1

[0048] For a single user, when the sound output device is a mobile device, the implementation process of outputting sound for the user.

[0049] see figure 2 , figure 2 It is a schematic diagram of the sound output flow in Embodiment 1 of the present application. The specific steps are:

[0050] In step 201, the sound output device is configured in a single-user mode.

[0051] The user can know in advance whether it is necessary to perform sound output for a single user or multiple users. Therefore, the sound output device can manually select single-user mode or non-single-user mode. When the sound output device receives the user's operation, it will follow the operation instruction to configure.

[0052] In step 202, the sound output device determines whether the user wears a wearable device that can be positioned, and if yes, executes step 203; otherwise, executes step 205.

[0053] Use the positioning module on the sound output device to determine whether the user wh...

Embodiment 2

[0091] For multiple users, when the sound output device is a mobile device, the implementation process of outputting sound for multiple users.

[0092] When the sound output device is a mobile device, if it is set to non-single-user mode, it will output sound according to the configured sound output mode. That is, the present application does not propose an improved technical solution for the sound output mode in this scenario.

Embodiment 3

[0094] For a single user, when the sound output device is a fixed device, the realization process of outputting sound for the user.

[0095] see Figure 4 , Figure 4 It is a schematic diagram of the sound output flow in Embodiment 3 of the present application. The specific steps are:

[0096] In step 401, the sound output device is configured in a single-user mode.

[0097] Step 402, the sound output device determines whether the corresponding user wears a wearable device that can be positioned, and if yes, executes step 403; otherwise, executes step 404.

[0098] In step 403, the sound output device determines the distance and angle between the user's location and the device using the positioning technology matched with the wearable device that can be positioned, and step 405 is executed.

[0099] Take the user watching TV in front of the TV as an example. When the user wears a wearable device that can be positioned, such as a Bluetooth watch, the location of the user is...

Abstract

The application provides an audio output method applied to an audio output device. The method comprises: according to the number of users needing to receive sounds and states of the users and the device, locations of the users as well as a distance and an angle of the device are determined based on a positioning technology; an audio output direction and an audio output region are determined based on the determined locations of the users and the distance and angle of the device; and sounds are outputted to the corresponding uses according to the determined direction and region. On the basis of the same conception, the application also provides an audio output apparatus. Therefore, the auditory-sense experience of the user is improved and the security is enhanced.

Description

technical field [0001] The invention relates to the technical field of intelligent positioning, in particular to a sound output method and device. Background technique [0002] There are the following sound output methods in the existing implementation: [0003] The first type: traditional speakers output sound. [0004] The sound transmission of traditional speakers cannot effectively control the direction and area of ​​sound transmission. The sound waves spread to a 360-degree spherical range, resulting in high loss, no directionality, and a lot of noise. [0005] The second type: physically control the direction of sound propagation, such as directional sound transmission TVs, control the direction of sound through sound insulation materials or speaker arrays. [0006] Physically controlling the direction of sound propagation limits the direction of the sound. The user can only cooperate with the device to listen to the sound in the relevant area, rather than the device...
