Step 110, establish the corresponding relationship between the playing state or working state of the wireless music playing device and the ambient light parameters;

Step 120, collect the ambient light intensity through the light sensor, obtain the digital value of the light intensity through analog/digital conversion, and transmit the digital value to the processor through the digital bus;

Step 130. Adjust the playing state or working state according to the corresponding relationship and the digital value.

In this embodiment, by sensing changes in ambient light, the player automatically adjusts its own playing state or working state to provide better user experience.

In this embodiment, the ambient light parameters include: ambient light intensity, the playing state includes: volume level, playing the next song, playing the previous song, and looping; the working state includes: on, off , pause; correspondingly, the corresponding relationship is: the volume increases or decreases as the ambient light intensity changes, and when the ambient light intensity is less than the preset first threshold, the wireless A music player device; when the ambient light intensity is greater than a preset second threshold, automatically turn on the wireless music player device and play music.

In this embodiment, there is one optical fiber sensor, which is installed on the front surface, upper surface, left surface, right surface or rear surface of the wireless music playback device.

As another embodiment, there are multiple optical fiber sensors, and they are installed on different housing surfaces among the front surface, upper surface, left surface, right surface or rear surface of the wireless music playback device.

In this embodiment, the digital bus is: I2C, UART or SPI.

In this embodiment, after the step 120 and before the step 130, it also includes:

Step 121, the processor acquires audio data through the network interface, and transmits the audio data to the audio amplification module after decoding or digital/analog conversion;

Step 122, the audio amplification module amplifies the power of the audio data to drive the speaker to produce sound.

In this embodiment, the network interface is: a wired network interface, a wireless network interface conforming to the 802.11 specification, or a Bluetooth wireless communication interface.

Embodiment two

In this embodiment, taking the relationship between volume and ambient light intensity as an example, the volume increases or decreases as the detected light intensity changes: if the volume ranges from 0 to 100, then the light intensity varies from none to maximum. The intensity is also divided into 100 levels. For each level of light intensity, the volume will increase by one level. For each level of light intensity decreased, the speaker will decrease by one level. It can be set that when the detected light intensity is lower than the preset first threshold, the playback device will automatically shut down, and it can also be set that when the detected light intensity is greater than the preset second threshold, it will automatically start and play music.

In this embodiment, the wireless music system is composed of multiple playback devices, and the volume change caused by a certain playback device due to the detected light intensity change will not affect the volume change of other playback devices. However, when shutting down or starting up due to changes in light intensity, the playback device needs to broadcast information to inform other playback devices in the wireless music system, so that other playback devices stop sending audio data and control data to the playback device.

Embodiment three

In this embodiment, take the number of ambient light flashes as an example to control wireless music. For example, when the playback device detects that the ambient light flashes twice within 3 seconds, the next song will be played; Flash 3 times in 3 seconds, pause playback, etc. The wireless music system is composed of multiple playback devices. The wireless music system is controlled by the light change mode, which is only effective for the playback devices covered by the light, and does not affect the working status of other playback devices in the wireless music system. For example, through the light in the bedroom, only one or more playback devices in the bedroom are controlled, while the playback status of the playback devices in other rooms is not affected.

Embodiment four

In this embodiment, a regional playback group can be quickly established through lights. The wireless music system consists of multiple playback devices, and these playback devices may be placed in many places (rooms) in the family. One or more players in the wireless music system can form a regional playback group (such as 2 playback devices in the living room), and play music synchronously. Through a preset change mode of the light, a regional playback group can be quickly formed . For example, when we want to form several playback devices in the living room into a regional playback group, we don't need to use the mobile phone to control, we only need to flash the lights in the living room 5 times within 5 seconds, and all the ambient light changes detected and the light intensity is greater than The playback device with a certain threshold automatically forms a regional playback group wirelessly to play music synchronously, which greatly simplifies the operation.
