Abstract
The utility model relates to an earphone composed of a timing alarm electronic clock, an interface circuit, a music integrate circuit and an amplifying circuit which are electrically connected with each other. The utility model make an audion on the interface circuit conduct by using an outputted signal from the timing alarm electronic clock, the signal's voltage is rised by the interface circuit and transmitted to the music integrate circuit, a weak signal outputted from the music integrate circuit is amplified by the amplifying circuit and is transmitted to a speaker to generate a timing alarm music, a switch K is added on the speaker for manual control of the alarming ring. The earphone has advantages that, people would not forget time during enjoying music, and the earphone has a reasonable structure, is easy to be manufactured and convenient to be used.
Description
Technical field
The utility model relates to a kind of earphone.
Background technology
Like the people who listens to the music very many in the modern society, often delay normal working and learning, also do not have a kind of alarm that in earphone, adds, make the audiophile not forget the time because of being drunk at music but indulge in music.
Summary of the invention
At the deficiencies in the prior art, the quarter-bell earphone that it is one that the utility model provides a kind of recreational practicality.
The purpose of this utility model is achieved through the following technical measures.
This earphone is made up of locking electronic clock, interface circuit, music integrated circuit and amplifying circuit, more than each device be electrically connected.
Described interface circuit is made up of triode, resistance, electric capacity, and each device is carried out and connected.
Described amplifying circuit is made up of triode and resistance, and triode is electrically connected with resistance.
Locking electronic clock output signal when the utility model uses, make the triode conducting on the interface circuit, signal interface circuit boosts, be sent to music integrated circuit, the weak signal of music integrated circuit output is amplified through amplifying circuit, be sent to loud speaker, send the locking music, for realizing that the Artificial Control of quarter-bell is added switch K at the loud speaker place.The advantage of this earphone be reminds people in enjoy music and as for forgetting the time, have rational in infrastructure, make advantages such as simple, easy to use.
