Abstract

A photoinduction loudspeaker, photoinduction loudspeaker control method and apparatus are provided. The photoinduction loudspeaker includes a loudspeaker and a photoinduction device. The photoinduction device is configured to acquire a light intensity value of an ambient environment where the loudspeaker is located and the photoinduction device transmits the light intensity value to the loudspeaker. The loudspeaker controls its own playing status based on the light intensity value. The photoinduction loudspeaker in the present invention is capable of identifying the ambient environment for selecting its own playing status based on the ambient environment in order to provide more intelligent service for a user.

First claim

What is claimed is:

1. A photoinduction loudspeaker, characterized in that the photoinduction loudspeaker comprises a loudspeaker and a photoinduction device;
wherein the photoinduction device is configured to acquire a light intensity value of an ambient environment where the loudspeaker is located and the photoinduction device transmits the light intensity value to the loudspeaker;
wherein the loudspeaker controls its own playing status based on the light intensity value; and
wherein when the light intensity value acquired by the loudspeaker decreases, the loudspeaker is configured to lower a volume level of playing songs; the loudspeaker is configured to select music styles and types based on the light intensity value acquired by the loudspeaker, and configured to play songs with the selected styles and types; and when the light intensity value acquired by the loudspeaker is less than a threshold value, the loudspeaker is configured to switch to a standby mode of the playing status based on the light intensity value, and wherein the playing status during the standby mode is further selected from one or more of the following: stopping the playback of songs and turning off the loudspeaker.

2. The photoinduction loudspeaker of claim 1 , characterized in that the photoinduction device comprises a photosensor and a transmission unit;
wherein the photosensor is configured to acquire the light intensity value of the ambient environment where the loudspeaker is located;
wherein the transmission unit is configured to transmit the light intensity value to the loudspeaker.

3. The photoinduction loudspeaker of claim 2 , characterized in that the photoinduction device further comprises an analog-to-digital converter;
wherein the photosensor is configured to acquire an analog value of the light intensity value of the ambient environment where the loudspeaker is located;
wherein the analog-to-digital converter is configured to acquire the analog value of the light intensity value into a digital value of the light intensity value.

4. The photoinduction loudspeaker of claim 1 , characterized in that the photoinduction loudspeaker further comprises a processor;
wherein the processor is connected to the photoinduction device via a digital bus, and is configured to receive the light intensity value, which is acquired by the photoinduction device, of the ambient environment where the loudspeaker is located, and controls the playing status of the loudspeaker based on the light intensity value.

5. A photoinduction loudspeaker control method, characterized in that the method comprises:
acquiring a light intensity value of an ambient environment where a photoinduction loudspeaker is located by the photoinduction loudspeaker; and
controlling a playing status of the photoinduction loudspeaker based on the light intensity value by the photoinduction loudspeaker;
wherein when the light intensity value acquired by the loudspeaker decreases, the loudspeaker is configured to lower a volume level of playing songs; the loudspeaker is configured to select music styles and types based on the light intensity value acquired by the loudspeaker, and configured to play songs with the selected styles and types; and when the light intensity value acquired by the photoinduction loudspeaker is less than a threshold value, the photoinduction loudspeaker is configured to switch to a standby mode of the playing status based on the light intensity value, and wherein the playing status during the standby mode is further selected from one or more of the following: stopping the playback of songs and turning off the loudspeaker.

6. The photoinduction loudspeaker control method of claim 5 , characterized in that acquiring the light intensity value of the ambient environment where the photoinduction loudspeaker is located comprises:
acquiring an analog value of the light intensity value of the ambient environment where the photoinduction loudspeaker is located and converting the analog value of the light intensity value into a digital value of the light intensity value by the photoinduction loudspeaker.

7. A photoinduction loudspeaker control apparatus, characterized in that the photoinduction loudspeaker control apparatus comprises:
an acquisition unit, configured to acquire a light intensity value of an ambient environment where a photoinduction loudspeaker is located; and
a playing control unit, configured to control a playing status of the photoinduction loudspeaker based on the light intensity value;
wherein when the light intensity value acquired by the loudspeaker decreases, the loudspeaker is configured to lower a volume level of playing songs; the loudspeaker is configured to select music styles and types based on the light intensity value acquired by the loudspeaker, and configured to play songs with the selected styles and types; and when the light intensity value acquired by the photoinduction loudspeaker is less than a threshold value, the photoinduction loudspeaker is configured to switch to a standby mode of the playing status based on the light intensity value, and wherein the playing status during the standby mode is further selected from one or more of the following: stopping the playback of songs and turning off the loudspeaker.

8. The photoinduction loudspeaker control apparatus of claim 7 , characterized in that the acquisition unit is configured to acquire an analog value of the light intensity value of the ambient environment where the photoinduction loudspeaker is located and converts the analog value of the light intensity value into a digital value of the light intensity value.

9. The photoinduction loudspeaker of claim 2 , characterized in that the photoinduction loudspeaker further comprises a processor;
wherein the processor is connected to the photoinduction device via a digital bus, and is configured to receive the light intensity value, which is acquired by the photoinduction device, of the ambient environment where the loudspeaker is located, and controls the playing status of the loudspeaker based on the light intensity value.

10. The photoinduction loudspeaker control method of claim 5 , characterized in that acquiring the light intensity value of the ambient environment where the photoinduction loudspeaker is located comprises: acquiring an analog value of the light intensity value of the ambient environment where the photoinduction loudspeaker is located and converting the analog value of the light intensity value into a digital value of the light intensity value by the photoinduction loudspeaker.

11. The photoinduction loudspeaker control apparatus of claim 7 , characterized in that the acquisition unit is configured to acquire an analog value of the light intensity value of the ambient environment where the photoinduction loudspeaker is located and converts the analog value of the light intensity value into a digital value of the light intensity value.
