Embodiment 1

[0036] figure 1 It is a flow chart of the volume control method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where the volume of the first playback device in the music playback system is too high and affects the second playback device (other playback devices in the music playback system). In the case of a playback effect, the method may be performed by the first playback device, and specifically includes the following steps:

[0037] Step 110, sequentially select a volume value from the set of preset volume values ​​to output a preset audio signal.

[0038] Wherein, the preset volume value set is composed of at least one volume value that can be output by the first playback device.

[0039] The preset audio signal can be a segment of audio signal, such as a song, a segment of recording, etc.; it can also be a segment of irregular sound waves, so as to distinguish it from conventionally played audio files. When the user sel...

Embodiment 2

[0051] The arrangement order of the volume values ​​in the preset volume value set may be random, and at this time, the volume values ​​read out sequentially are also random. There may be a situation where the read volume value is greater than the actual volume threshold. At this time, the false volume threshold determined according to the threshold feedback information sent by the second playback device will be greater than the actual volume threshold. As a result, when outputting according to the false volume threshold, still There are cases where the output volume value is higher than the actual volume threshold, making the determined volume threshold inaccurate.

[0052] In order to solve the above problems, this embodiment provides a volume control method. As a specific description of Embodiment 1, step 110, sequentially selecting a volume value from the preset volume value set to output a preset audio signal includes: Select a volume value in order from small to large in...

Embodiment 3

[0080] This embodiment provides a volume control method, and the method is used to cooperate with the method provided in Embodiment 1 to realize volume control. The method is applied to a second playback device, such as Figure 4 As shown, the method includes:

[0081] Step 210: Receive a preset audio signal output by the first playback device.

[0082] The second playback device has an audio input device such as a microphone and a recording circuit connected to the microphone. The preset audio signal input by the first playback device is received through the audio input device.

[0083] Step 220, acquiring the strength of the preset audio signal.

[0084] The unit of the intensity of the preset audio signal is decibel. For a specific implementation manner of obtaining the strength of the audio signal according to the audio signal, reference may be made to related content in the prior art, and details are not described here.

[0085] Step 230: If the intensity of the pres...

Abstract

The invention discloses a volume control method, playing equipment and a system. A volume value is selected in sequence from a preset volume value set to output preset audio signals, and the preset volume value set is formed by at least one volume value outputted by first playing equipment; if threshold feedback information sent by second playing equipment is received, the current volume value is confirmed as the volume threshold, and the threshold feedback information is used for expressing that the intensity of the audio signals received by the second playing equipment is higher than the preset threshold; and the target audio signals are outputted according to the volume threshold. According to the volume control method, the playing equipment, and the system, the target audio signals can be outputted according to the volume threshold, the volume value of the target audio signals is no greater than the volume threshold, interferences of the audio signals outputted by the playing equipment can be prevented, and the playing effect of the playing equipment is optimized.

Description

technical field [0001] Embodiments of the present invention relate to electronic device control technology, and in particular to a volume control method, playback device and system. Background technique [0002] With the development of wireless network technology, wireless network technology is widely used in the field of music playback. Some music player equipment manufacturers connect multiple music player devices through wireless networks to form a music player system composed of multiple music player devices. [0003] The user groups the audio playback devices in the music playback system through the smart terminal to obtain multiple playback groups. The user controls the playback groups located in different areas to play different music to achieve personalized settings. For example: set two music playback devices in the living room as the first playback group, and set one music playback device in the bedroom as the second playback group. Then, the user controls the f...
