Abstract

A design of the utility model relates to a headphone with an LED indicator light which comprises an audio signal input module, an LED driving module and an LED circuit module. The LED driving module is respectively connected with the audio signal input module and the LED circuit module. The LED circuit module is controlled through receiving audio signals of the audio signal input module. Through the LED indicator light installed on the headphone, a user is easy to be found when wearing the headphone to listen to the music at night. A problem that the user is uneasy to be found to cause dangers is effectively solved. And the strength of audio signals of sound played by the headphone can be intuitively seen by the user, which brings conveniences to the user. The utility model has the advantages of reasonable structure design and enhanced function of the headphone at the premise of not influencing the normal use of the headphone.

Description

A kind of earphone that has LED light

Technical field

The utility model relates to a kind of earphone that has LED light, relates in particular to a kind ofly when audio signal is imported, and the led light source on the earphone can carry out glittering a kind of earphone that has LED light with the power of audio signal.

Background technology

Existing earphone only has the function of the music listened on the market, does not have the function of flashing light, when the user wears earphone night and carries out activity out of doors and listen to music, because earphone does not have the flashing light function, the user is shrouded by the curtain of night, be not easy to be found, be easy to cause danger by the people.Also have; existing earphone is when playing back music; the power of audio signal can not show intuitively; particularly working as earphone is connected with external played equipment; when the volume of external played equipment is very big; because the user can not intuitively learn the power of audio signal, regular meeting makes ear be subjected to the stimulation of big volume because of careless directly the use.

The utility model content

For solve exist in the prior art because earphone does not have LED light, have potential hazard when the user is used night and can not discern the technical problem of audio signal power, the utility model provides a kind of earphone that has LED light.

The utility model solves the problems of the technologies described above the scheme that is adopted: a kind of earphone that has LED light is provided, and the described earphone that has LED light comprises audio signal input module, LED driver module and led circuit module; Described LED driver module is connected with described led circuit module with described audio signal input module respectively, by the audio signal that receives described audio signal input module described led circuit module is controlled.

According to a preferred embodiment of the present utility model: described LED driver module is to be installed in the LED control chip on the wiring board in the fuselage.

According to a preferred embodiment of the present utility model: described LED control chip can provide 5 paths of LEDs level to drive output.

According to a preferred embodiment of the present utility model: described led circuit module comprises eight LED branch roads, and per two described LED branch roads are one group.

According to a preferred embodiment of the present utility model: described earphone casing is provided with loophole, and described led light source can be derived in described loophole.

The beneficial effects of the utility model are: by the LED signal lamp is installed on earphone, make the user when wearing earphone and listen to music night, be easy to be found by the people, efficiently solve the generation of the danger that causes because the user is not easy to be found by the people, and the power of the audio signal that earphone played sound can be seen more convenient user's use intuitively by the user.The utility model reasonable in design not influencing under the normal prerequisite of using of earphone, makes the function of earphone obtain enhancing.

Fig. 2. have the head circuit schematic diagram of LED light;

Fig. 3. have the earphone external structure schematic diagram of LED light.

Embodiment

The utility model is described in further detail below in conjunction with drawings and embodiments.

See also a kind of earphone modular structure block diagram that has LED light of Fig. 1, a kind of earphone that has LED light of the utility model comprises audio signal input module 101, LED driver module 102 and led circuit module 103 as shown in Figure 1; Described LED driver module 102 is connected with described led circuit module 103 with described audio signal input module 101 respectively, by the audio signal that receives described audio signal input module 101 described led circuit module 103 is controlled.

See also a kind of head circuit schematic diagram that has LED light of Fig. 2.Comprise audio signal input module 101, LED driver module 102 and led circuit module 103 as shown in Figure 2 in this circuit diagram.Described LED driver module 102 is a LED control chip 201, provides 5 paths of LEDs level to drive output.Described led circuit module comprises eight LED branch roads, and per two described LED branch roads are one group.

In the work, audio signal is input to the pin 8 of LED control chip 201 through capacitor C 2 and resistance R 10,201 work of LED control chip provide five paths of LEDs level to drive output, be the 1st, 2,3,4 and 6 pins of LED control chip, along with changing from weak to strong of audio signal, LED then can light successively according to the order of D1D5, D2D6, D3D7 and D4D8, and it is luminous to glimmer along with the fluctuating of audio signal.

See also the earphone external structure schematic diagram that Fig. 3 has LED light.LED light can come out by printing opacity from the corresponding loophole 302 that earphone casing 301 is provided with as shown in Figure 3.

The utility model is by installing the LED signal lamp on earphone, make the user when wearing earphone and listen to music night, be easy to be found by the people, efficiently solve the generation of the danger that causes because the user is not easy to be found by the people, and the power of the audio signal that earphone played sound can be seen more convenient user's use intuitively by the user.The utility model reasonable in design not influencing under the normal prerequisite of using of earphone, makes the function of earphone obtain enhancing.

Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
