Embodiment 1

[0040] Please see figure 1 , figure 1 A schematic flowchart of an audio synchronization adjustment method is provided for the embodiment of the present application. The method is applied to a first audio device, and the first audio device communicates with a second audio device, wherein the audio synchronization adjustment method includes:

[0041] S101. When an audio operation instruction is detected, forward the audio operation instruction to the second audio device, so that the second audio device performs audio adjustment according to the audio adjustment instruction at the audio operation moment; wherein the audio operation instruction includes the audio operation moment and the audio adjustment instruction.

[0042] In this embodiment, the first audio device and the second audio device have the ability to communicate with each other, which may be wireless or wired, which is not limited in this embodiment.

[0043] S102. Extract the audio operation time and the audio a...

Embodiment 2

[0050] Please see figure 2 , figure 2 It is a schematic flowchart of an audio synchronization adjustment method provided by the embodiment of the present application. The method is applied to a first audio device, and the first audio device communicates with a second audio device, wherein the audio synchronization adjustment method includes:

[0051] S201. Establish a communication connection with the second audio device, and synchronize clock times of the first audio device and the second audio device.

[0052] As an optional implementation manner, the step of establishing a communication connection with the second audio device and synchronizing the clock time of the first audio device and the second audio device may include:

[0053]A communication connection is established with the second audio device, and clock synchronization processing is performed on the clock time of the first audio device and the clock time of the second audio device.

[0054] Implementing this i...

Embodiment approach

[0075] As an optional implementation, the method also includes:

[0076] Sending confirmation reception information to the second audio device, so that the second audio device knows that the first audio device has received the above confirmation information.

[0077] In this embodiment, after the two-way confirmation is completed, the first audio device and the second audio device perform audio adjustment synchronously.

[0078] As an optional implementation manner, when the confirmation information fed back by the second audio device is not received, the method further includes:

[0079] Detect whether the negative information fed back by the second audio device is received.

[0080] In this embodiment, the denial information may include NACK, that is, explicit denial information.

Abstract

The invention provides an audio synchronization adjustment method and audio equipment.The audio synchronization adjustment method is applied to first audio equipment, the first audio equipment is in communication connection with second audio equipment, and the audio synchronization adjustment method comprises the steps that when an audio operation instruction is detected, the audio operation instruction is forwarded to the second audio equipment, the second audio equipment carries out audio adjustment according to the audio adjustment instruction at the audio operation time and the audio operation moment; wherein the audio operation instruction comprises audio operation time, audio operation moment and an audio adjustment instruction; extracting an audio operation time, an audio operation moment and an audio adjustment instruction included in the audio operation instruction; and performing audio adjustment according to the audio adjustment instruction at the audio operation time and the audio operation moment. Therefore, by implementing the implementation mode, when a user uses a single audio device to carry out audio adjustment, the synchronization precision of the multiple audio devices can be improved to a microsecond level, so that the synchronization effect of the multiple audio devices is improved.

Description

technical field [0001] The present application relates to the field of audio processing, and in particular, to an audio synchronization adjustment method and audio equipment. Background technique [0002] There are more and more wirelessly synchronized audio products, and users have higher and higher requirements for each product. Among them, the synchronization requirements for multiple headphones or speakers are higher. In practice, users' requirements for synchronization have reached the microsecond level. However, in the process of using the current product, users often operate on a single audio device, which makes it difficult for multiple audio devices to achieve microsecond-level synchronization in the actual synchronization process. Contents of the invention [0003] The purpose of the embodiment of the present application is to provide an audio synchronization adjustment method and an audio device, which can improve the synchronization accuracy of multiple audio ...
