Embodiment 1

[0023] figure 1 A schematic structural diagram of an indicating circuit provided by an embodiment of the present invention is shown. The indicating circuit 10 includes a driving circuit 101 and a cold light sheet 102, and the cold light sheet 102 is arranged on the earphone 30;

[0024] The driving circuit 101 is configured to receive a clock frequency determined by the mobile terminal 20 according to the volume of the earphone 30, and output a driving signal corresponding to the clock frequency to the cold light sheet 102;

[0025] The cold light sheet 102 is configured to receive the driving signal, and emit light according to the driving frequency of the driving signal, so as to indicate the volume of the earphone 30 according to the emitted light.

[0026] In this embodiment, the mobile terminal 20 determines the clock frequency according to the volume of the earphone 30 . Specifically, when the volume of the earphone 30 is high, the determined clock frequency is high; w...

Embodiment 2

[0029] An embodiment of the present invention provides an indicating circuit, and the indicating circuit 10 of this embodiment is implemented on the basis of the first embodiment.

[0030] refer to figure 2 The schematic diagram of the structure of the driving circuit is shown, the driving circuit 101 includes a driving chip 1011, and the driving chip 1011 is provided with a clock signal input terminal CLK and a driving signal output terminal EL1, EL2;

[0031] The clock signal input terminal CLK is connected to the clock signal output terminal ClkOut of the mobile terminal, and the driver chip 1011 receives the clock signal output by the mobile terminal 20 according to the volume of the earphone 30;

[0032] The driving signal output terminals EL1 and EL2 are connected to the EL sheet 102, the driving chip 1011 outputs a driving signal to the EL sheet 102, and the driving frequency of the driving signal corresponds to the clock frequency of the clock signal.

[0033] In thi...

Embodiment 3

[0049] Figure 7 An indication method provided by an embodiment of the present invention is shown, and the method includes:

[0050] Step 401, the mobile terminal determines the clock frequency according to the volume of the earphone, and outputs it to the driving circuit.

[0051] In this embodiment, the mobile terminal 20 determines the clock frequency according to the volume of the earphone 30 . Optionally, the mobile terminal 20 determines the clock frequency according to the percentage of the volume of the earphone 30 to the total volume and the range of the clock frequency. Specifically, the clock frequency may be the product of the percentage Vol of the volume in the total volume and the range of the clock frequency. Wherein, the clock frequency is between 32kHz-400kHz. For example, if the playback volume Vol of the earphone 30 accounts for 30% of the total volume, and the clock frequency range is 368kHz, then the clock frequency is 368kHz*30%=110.4kHz. After the mo...

Abstract

The invention provides an indicating circuit and method. The indicating circuit comprises a driving circuit and an electroluminescent panel; the electroluminescent panel is arranged on a headset; thedriving circuit is used for receiving a clock frequency determined by a mobile terminal according to a volume of the headset, and outputting a driving signal corresponding to the clock frequency to the electroluminescent panel; and the electroluminescent panel is used for receiving the driving signal and giving out light according to a driving frequency of the driving signal, so as to indicate thevolume of the headset according to the light given out. According to the indicating circuit and method provided by the embodiment of the invention, a user can distinguish whether the headset plays amusic or not and a size of the volume according to the light given out by the electroluminescent panel; and not only can the user be reminded of turning off the music to save power consumption, but also the problem of eardrum stimulation due to the fact that the user directly wear the headset when the volume of the headset is overhigh can be avoided.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an indicating circuit and method. Background technique [0002] With the development of science and technology, mobile terminals have gradually become an indispensable communication tool in people's work and life. Users use mobile terminals to talk, listen to music, watch videos, etc., and users often use earphones when listening to music or watching videos. In the prior art, earphones only meet the user's listening needs, but cannot meet the user's needs in some application scenarios. For example, when a mobile terminal plays music through earphones, the user cannot tell whether the earphones are playing music from the appearance of the earphones, and needs to wear the earphones for confirmation, or check the mobile terminal for confirmation; and, when the mobile terminal plays music through the earphones, if the earphone volume If it is too high, the eardrum will be ir...
