Detailed ways

The scheme of this application is further described in conjunction with the accompanying drawings as follows:

As shown in Figures 1-4 and 7, Embodiment 1 of the present invention:

A color-changing earphone based on human physiological signals, comprising a sound source connector 1, a broadcast unit 2, a wire control device 3 and a sound source line 4, the sound source line 4 is divided into a first section 41 connecting the sound source connector 1 and the wire control device 3, And the second section 42 connecting the wire control device 3 and the broadcast unit 2; the broadcast unit 2 includes a first housing 21 with a sound hole and a second housing 22 forming a receiving cavity 23 with the first housing 21 The loudspeaker 5 and the first full-color LED light source 61 are accommodated in the receiving cavity 23, and the first full-color LED light source 61 is controlled by the microcontroller 7 arranged in the line control device 3; the broadcasting unit 2 and/or the wire control device 3 is provided with a sensing device 8 for acquiring human physiological signals, the signal output end of the sensing device 8 is connected to the microcontroller 3, and the microcontroller 3 is based on the obtained human body physiological signal Physiological information changes to control the light output effect of the first full-color LED light source 61; the sensing device 8 includes a heart rate sensor 81 for acquiring changes in the heart rate of the human body and/or a temperature sensor 82 for acquiring changes in the temperature of the human body.

The working principle of the above scheme: the infrared heart rate sensor 81 and the temperature sensor 82 detect the heart rate and body temperature data of the earphone wearer, and transmit the heart rate and body temperature data to the microcontroller 7;

When the heart rate of the earphone wearer increases, the infrared heart rate sensor 81 gradually reduces the output level value, and the microcontroller 7 drives the first full-color LED light source 61 to increase the light flickering frequency. Conversely, when the heart rate of the earphone wearer slows down, the infrared heart rate sensor 81 gradually increases the output level value, and the microcontroller 7 drives the first full-color LED light source 61 to reduce the light flickering frequency;

Similarly, when the body temperature of the earphone wearer rises, the temperature sensor 82 gradually increases the output level value, and the microcontroller 7 drives the first full-color LED light source 61 to emit light whose color depth varies according to the level value, for example, the body temperature The higher the value, the darker the red light emitted. Conversely, when the body temperature of the wearer of the earphone drops or the temperature of the earphone is lowered by taking off the earphone, the temperature sensor 82 gradually reduces the output level value, and the microcontroller 7 drives the first full-color LED light source 61 to emit color depth according to the level value. Changing light, for example, the lower the body temperature, the lighter the blue light emitted.

The second housing 22 has an annular slot 24, and the slot 24 has a light exit hole or a light exit slit 241 that communicates with the receiving cavity 23, and the slot 24 is provided with an annular light guide strip 25 , the light emitted by the first full-color LED light source 61 enters the ring-shaped light guide strip 25 through the light exit hole or light exit slit 241 .

When a heart rate sensor 81 is provided, the heart rate sensor 81 is set in the wire control device 3, and its signal output end is connected to the signal input end of the microcontroller 7;

When a temperature sensor 82 is provided, the temperature sensor 82 is set in the broadcast unit 2, and its signal output terminal is connected to the signal input terminal of the microcontroller 7 through the signal line 43 arranged along the second section 42 of the audio source line.

In this implementation, the broadcasting unit 2 is preferably an earplug, and the earplug is placed in the ear hole of a person to facilitate the measurement of body temperature changes.

The wire control device 3 has a built-in lithium battery and a corresponding power supply circuit, and the power supply circuit is connected to a charging interface 31 located at the side or end of the wire control device 3 shell.

On the basis of the above scheme, the following extensions can also be made:

The wire control device 3 is also provided with a second full-color LED light source 62 controlled by the microcontroller 7, and a light guide fiber 44 is arranged along the second section 42 of the sound source line. One end of 44 is opposite to the second full-color LED light source 62 ;

In this embodiment, the optical fiber structure is used as an extension of the above-mentioned solution, and it can also be implemented independently, so that only the part of the sound source line has a color change.

As shown in Figures 5-6, Embodiment 2 of the present invention differs from Embodiment 1 above in that: the second housing 22 is transparent as a whole or partially transparent, so that the first full-color LED light source 61 emits The light is emitted from the transparent portion 221 of the second housing 22 .

In actual production, the second housing 22 and\the first housing 21 may also be soft transparent entities made of light-guiding materials.

The above-mentioned preferred implementation mode should be regarded as an illustration of the implementation mode of the scheme of this application, and any technical deduction, replacement, improvement, etc. that are similar to, similar to, or based on the scheme of this application should be regarded as the scope of protection of this patent.
