Abstract

The utility model discloses a headset timer serially connected to a headset cord. The headset timer comprises a single-chip microcomputer, a sound acquisition module, a timing device, an alarm and a switch serially connected to the headset cord. An input end of the single-chip microcomputer is respectively connected with an output end of the sound acquisition module and an output end of the timing device. An output end of the single-chip microcomputer is connected with the alarm and the switch. The headset timer helps people develop good habits of using headsets to prevent hearing from being impaired by long-term use of the headsets.

Description

The earphone timing device

Technical field

The utility model relates to audio-visual equipment field, particularly a kind of timing device that is applied on earphone.

Background technology

Day by day universal along with portable players such as walkman, CD, MP3, MP4 is for people's life brings very big enjoyment.The young man likes earphone is clogged ear, sound is amplified, in order to put into physically and mentally in the audiovisual world of oneself.But due to the long-time earphone that uses, cochlea, ear-drum are produced arrive infringement, easily cause user's Hearing, serious also may cause deafness.Therefore cultivating the good use earphone custom of people is to guarantee the normal necessary means of hearing.

Summary of the invention

The technical problem that the utility model solves is to provide a kind of timing device that is applied on earphone, can be helping people to cultivate good earphone use habit, to prevent impaired hearing.

For solving the problems of the technologies described above, technical solution adopted in the utility model is:

The earphone timing device, described timing device is serially connected on earphone cord, timing device comprises single-chip microcomputer, sound collection module, timer, alarm and is serially connected in switch on earphone cord, the input of described single-chip microcomputer is connected output with the output of sound collection module respectively and is connected with timer, the output of single-chip microcomputer connects alarm and switch.

Improvement of the present utility model is: described timing device also comprises for showing that earphone uses the display screen of timing and earphone dormancy time.

Owing to having adopted above technical scheme, the obtained technological progress of the utility model is:

The utility model can arbitrarily be set earphone service time, and according to the service time corresponding time of having a rest of configuration, when earphone reaches the service time of setting service time, the utility model can cut off sound automatically, send warning, the reminding user earphone arrives continuous service time, enters simultaneously resting state.After the earphone dormancy time finishes, automatically connect sound, the user can continue to use earphone.The utility model can show time and the earphone dormancy time that uses earphone by display screen in observation process, be convenient to the user and watch.

Description of drawings

Fig. 1 is structured flowchart of the present utility model.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.

The earphone timing device is serially connected on earphone cord, is used for controlling cut-out or the connection of earphone sound, and its structured flowchart is shown in Figure 1.Timing device comprises single-chip microcomputer, sound collection module, timer, alarm, display screen and is serially connected in switch on earphone cord.The sound collection module is used for gathering on earphone cord whether transfer voice is arranged, and collection result is passed to single-chip microcomputer in real time.Timer is used for setting continuous service time according to user's user demand, and is transferred to single-chip microcomputer the continuous service time that will set.Single-chip microcomputer is used for according to the transfer voice situation that gathers and sets the operating state of controlling alarm and switch continuous service time.Alarm is used for sending according to the instruction of single-chip microcomputer and pipes, and arrives continuous service time with reminding user, and ear needs to have a rest.Switch is used for cutting off or connect sound source according to the instruction of single-chip microcomputer.The input of display screen connects the output of single-chip microcomputer, is used for showing that earphone uses timing and earphone dormancy time.

When the utility model uses, can according to user's demand, set continuous service time of earphone and earphone dormancy time on timer; Timer is sent the time value of input into single-chip microcomputer, the transfer voice state that single-chip microcomputer gathers in conjunction with the sound collection module, beginning timing.When the earphone of setting arrived continuous service time, the Single-chip Controlling alarm sent warnings that pipe, and control switch cuts off transfer voice simultaneously, thereby reaches the situation of the uncontrolled use earphone of restriction user, thereby protects user's the sense of hearing to be without prejudice.
