Description

Technical Field

[0001] The utility model relates to the technical field of Bluetooth earphones, in particular to a Bluetooth earphone with a power display function. Background Art

[0002] In recent years, the Bluetooth headset market has continued to prosper. Among them, true wireless headsets still dominate, accounting for 55%. As consumers' requirements for sound quality, comfort, intelligence, etc. continue to increase, the Bluetooth headset industry is ushering in a new round of technological innovation and market competition.

[0003] When a Bluetooth headset is in use, it is necessary to rely on an energy storage battery to maintain its battery life to meet the daily use needs of the user. Therefore, existing Bluetooth headsets are usually equipped with a charging compartment for charging the Bluetooth headset. However, some Bluetooth headset bodies or Bluetooth headset charging compartments usually do not have a power display function. The reason is that displaying the power level requires additional power consumption, thereby reducing the battery life of the Bluetooth headset, or a device for displaying the power level is provided on the Bluetooth headset, but the user cannot see the power level of the Bluetooth headset when wearing the headset. Moreover, existing Bluetooth headsets are unable to display the power level of the charging compartment energy storage battery, Bluetooth headset battery one, and Bluetooth headset battery two, and may only have a single display, resulting in an incomplete display, which makes the user's judgment of the power level error when using it, thereby reducing the user's experience.

[0004] Therefore, we propose a Bluetooth headset with a battery display function to solve the above-mentioned technical problems. Utility Model Content

[0005] In view of this, the present invention overcomes the shortcomings and its main purpose is to provide a Bluetooth headset with a power display function, which serves to solve the above-mentioned problem.

[0012] As a preferred solution, the RGB three-color lights are provided in three groups, and the three groups of RGB three-color lights are equidistantly distributed on the outside of the Bluetooth headset charging compartment.

[0013] As a preferred solution, the RGBRGB three-color lamp driving circuit is electrically connected to the main control chip and multiple groups of the RGB three-color lamps respectively. The main control chip converts the detection signal transmitted by the BQ27425 chip into a corresponding driving signal command, and then transmits it to the RGB three-color lamp driving circuit through the I2C bus. The RGB three-color lamp driving circuit executes the driving signal command issued by the main control chip to control the multiple groups of the RGB three-color lamps to emit light.

[0014] As a preferred solution, the Bluetooth headset charging compartment also includes a charging protection circuit and a charging interface.

The power detection module 7 includes a BQ27425 chip. An I2C bus for transmitting a detection signal is connected between the BQ27425 chip and the main control chip. When the charging warehouse energy storage battery 6 charges or stores the Bluetooth headset battery 1 and the Bluetooth headset battery 2, the power detection module 7 can detect the power of the charging warehouse energy storage battery 6, the Bluetooth headset battery 1 and the Bluetooth headset battery 2, and then transmit the detection signal to the main control chip through the I2C bus, and the main control chip analyzes the detection signal;

[0028] Multiple groups of RGB three-color lights are respectively used to display the remaining power of the Bluetooth headset charging compartment 1 or the two groups of Bluetooth headset bodies 3, and the multiple groups of RGB three-color lights are equidistantly distributed on the outside of the Bluetooth headset charging compartment 1;

[0029] The RGB three-color lamp driving circuit 8 is used to drive multiple groups of RGB three-color lamps to emit light. The RGB three-color lamp driving circuit 8 includes an SQL2811 driving chip. The RGBRGB three-color lamp driving circuit 8 is electrically connected to the main control chip and the multiple groups of RGB three-color lamps respectively.

[0030] See also Figures 1 to 3 There are three groups of RGB three-color lights, which can emit red light, yellow light or green light. The RGB three-color light driving circuit 8 receives the driving signal command issued by the main control chip, so that multiple groups of RGB three-color lights emit red light, yellow light or green light respectively, which are used to respectively display the power of the Bluetooth headset charging compartment 1 and the two groups of Bluetooth headset bodies 3.

[0031] See also Figures 1 to 3The main control chip receives the detection signal emitted by the power detection module 7, and divides the detection result into three levels, less than 20%, 20% to 60% or greater than 60%, and then converts it into a driving signal command and transmits it to the RGB three-color light driving circuit 8. The RGB three-color light driving circuit 8 drives multiple groups of RGB three-color lights to emit red light, yellow light or green light respectively. The red light, yellow light or green light emitted by the three groups of RGB three-color lights can be used to respectively indicate the power of the two groups of Bluetooth headset bodies 3 and the charging warehouse energy storage battery 6. It should be noted that when the three groups of RGB three-color lights are completed, the RGB three-color light in the middle is used to display the power indication of the charging warehouse energy storage battery 6, and the other two groups of RGB three-color lights are respectively located on the left and right sides of the group of RGB three-color lights, corresponding to the remaining power of the Bluetooth headset battery contained in the Bluetooth headset body 3.
