Abstract
The utility model discloses an earphone with a posture prompting function, which has the technical scheme that a posture indicator (A) which is connected in series with a traditional earphone circuit, a sounding music chip (B) and a time delay circuit (E) which is simultaneously used for adjusting the alarming time of the sounding music chip (B). The posture indicator (A) is composed of a plastic plate (5), a metal ring (6), a metal rod (7), a metal ball (8), insulating liquid (9), a conducting wire (10), a rotating shaft (11) and an outer shell (12). The metal rod (7) and the metal ball (8) can swing with the incline of the head under the action of gravity, if the swinging angle exceeds the setting range, the metal rod (7) will touch the metal ring (6), and the time delay circuit (E) and a battery (1) are switched on. The utility model overcomes the problem that users wearing the earphone ignore the head posture.
Description
Technical field
The utility model relates to the stereo set in the daily living article, relates to the earphone of a kind of attached headband and receiver specifically.
Background technology
Although public earphone has had bigger improvement on pattern and function at present, but thereby the problem that the habitual sagging posture of the head that the wearer occurs when using earphone is for a long time oppressed the cervical vertebra nerve is still unresolved, vast earphone user often ignores the posture of head in wearing the earphone process, can not get for a long time correcting, be easy to bring out chronic diseases such as cervical vertebra hyperplasia and myopia.
The utility model content
The purpose of this utility model just provides a kind of earphone that has the pose reminding function, and it can remind the user to note the posture of head when wearing earphone.
The technical scheme that the utility model addresses the above problem is, utilizes gravity principle, is input parameter with this analog quantity of posture of human body head, by the disconnection and the closure of circuit, through the delay circuit time-delay, realizes the purpose of signal of telecommunication guide sound tone signal.
The utility model increases a part of circuit in earphone original sound amplifying circuit, it comprises delay circuit, sounding Music Clip circuit.Two circuit parallel connections are connected with posture indicating device and switch, battery again.Delay circuit is in parallel with sounding Music Clip both positive and negative polarity, with the time of control sound horn.The posture indicating device is equipped with pendulum, and habitual when sagging to a side at people's head, pendulum will be swung under action of gravity in the opposite direction, Metallic rod contacting metal ring, and delay circuit and sounding musical film circuit turn-on, delay circuit charges.If people's head keeps curved position, delay circuit is with conducting, and the sounding Music Clip control loudspeaker that are electrically connected with it send music, the head pose of reminding the user to correct a mistake.
Posture indicating device in the utility model utilizes the work of pendulum, change in location and becket height change by plastic sheet, rational warning threshold is set, and this complicated record of grid bearing with human body head is converted into conducting (0) and disconnects the simple record of discerning easily in (1) these two kinds of circuit cleverly.
The utility model compared to prior art, its advantage and benefit are embodied in:
1. cost is lower, and technology is simple.
2. be widely used, adaptability is good.

Embodiment
Below in conjunction with the specification drawings and specific embodiments explanation earphone that the utility model has the pose reminding function is further described.
Circuit diagram of the present utility model as shown in Figure 1, circuit of the present utility model comprises battery 1, switch 2, posture indicating device A, variable resistor C, loudspeaker 3,4, patch jack D, sounding Music Clip B, delay circuit E etc.
Switch 2 is in closure state when earphone uses.
Variable resistor C regulates the size of current by loudspeaker 3,4 circuit, is used for regulating the size of loudspeaker 3,4 volumes.
Sounding Music Clip B, posture indicating device A and battery 1 series connection, delay circuit E is in parallel with sounding Music Clip B.

The structure chart of posture indicating device A as shown in Figure 2, the shell 12 of this indicating device is an airtight container, draws lead 10 places in circuit from rotating shaft 11 and becket 6.Rotating shaft 11 is connected with Metallic rod 7, and Metallic rod is connected to Metal Ball 87 times, and Metallic rod 7 and Metal Ball 8 are affixed and can be around rotating shaft 11 swings.In the both sides of Metallic rod 7 plastic sheet that can move horizontally 5 is arranged respectively, plastic sheet 5 inboards are connected to the becket 6 that can move up and down.
This posture indicating device A is when human body head is in normal posture, and Metallic rod 7 is delayed time and sounding Music Clip parallel circuits and battery 1 disconnection straight down; When human body head was in improper posture, Metallic rod 3 and Metal Ball 4 to the opposite direction swing of human body head incline direction, contacted the becket 6 of this side, time-delay and sounding Music Clip parallel circuits and battery 1 conducting, delay circuit E capacitor C under action of gravity
2Charging.
Be filled with iknsulating liquid 9 in the shell of this posture indicating device A.Iknsulating liquid 9 makes Metal Ball 8 swing more steadily in the cavity of shell 12, has slowed down the cycle of swing, reduced Metallic rod 7 with noise and the mechanical wear of becket 6 when contacting.
The triode T of delay circuit
2Emitter is electrically connected with sounding Music Clip B, is used for controlling the phonation time of sounding Music Clip B.Usually after the human body head posture was in abnormal condition and continues for some time, sounding Music Clip B control loudspeaker 3,4 were reported to the police.
The utility model can be of wide application, the execution mode and the field that are not limited in this specification to be mentioned.For the professional in present technique field, any improvement that the utility model embodiment is done or change do not exceed the protection range of spirit of the present utility model and claims.
