Abstract
The invention discloses a passive light-emitting earphone. The passive light-emitting earphone comprises an earphone housing, a loudspeaker, a plug and wires that are electrically connected with the above parts. The passive light-emitting earphone further comprises an LED lamp board, a passive drive circuit electrically connected with the LED lamp board, and a light guide assembly matched with the LED lamp board. The loudspeaker, the LED lamp board and the light guide assembly are mounted in the earphone housing. According to the technical scheme of the invention, audio signals are fully utilized as a drive source for an LED. In this way, not only the loss of the audio quality is avoided, but also an in-ear/head-mounted type earphone or even audio equipment can dazzle with brilliance and shine with dazzling brilliance along with the music (audio) playing process without the adoption of any extra external/built-in power supply. Based on the passive light-emitting technique, the in-ear type earphone can emit the light. Meanwhile, the size of the earphone is not increased excessively due to the adoption of the above parts. The passive light-emitting technique thoroughly solves the problem of potential safety hazards caused by batteries themselves. The passive light-emitting earphone is zero in loss, small in size and free from being charged even after being used for a long time.
Description
Technical field
The present invention relates to earphone field, particularly passive luminous earphone.
Background technology
Existing luminous class earphone adopts two kinds of modes:
One is external power source, and 5V power supply or access external power supply as passed through computer USB coordinate interlock circuit driving LED luminous.This mode can only be used for the larger headphone of volume.Can only for computer (namely having the equipment of USB port), or have civil power place could realize luminescence, use and have significant limitation and can computer USB interface be taken, carry inconvenience, and cannot energy-conserving and environment-protective be realized.
Another kind of mode be adopt once or secondary cell (secondary cell is chargeable battery, as lithium battery) as the energy, and join dependency drives LED is luminous.This mode enters battery owing to having added, the invisible volume adding earphone, product can not be accomplished very little (especially In-Ear Headphones), but also irregularly will charge to earphone, as long-time not to its charging, battery is easy to scrap because of overdischarge, and the risk as adopted lithium battery to there is blast on fire.
Summary of the invention
