All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, a train arrival reminding device capable of adjusting capacitance according to received audio changes comprises a chair 1, wherein a power supply 2 is fixedly installed on the inner side wall of the chair 1, the power supply 2 is a KMS-25-12 full-bridge rechargeable battery, the power supply 2 is fixedly connected with two symmetrical polar plates 4 through a wire 3, the polar plates 4 are fixedly installed on the inner rear wall of the chair 1, a fixed electrode 5 and a metal film 6 are fixedly installed between the two symmetrical polar plates 4, the fixed electrode 5 is RS-131, the metal film 6 and the fixed electrode 5 are respectively located at two ends of the polar plates 4, the metal film 6 is located on the right side of the fixed electrode 5, the distance between the metal film 6 and the fixed electrode 5 is one centimeter to one point five centimeters, and mainly the change of capacitance can be better checked.

Through wire 3, fixed

electrode

5 and 6 cooperation use of metal film, can effectually turn into audio current with the sound that the trainman reported, turn into audio voltage by resistance 7 again to this magnetism intensity of controlling electro-magnet 8 to the action bars 11 side-to-side movement strikes back cushion 14, awakens the somnolence tourist.

The upper polar plate 4 is fixedly connected with a resistor 7 through a wire 3, the upper end of the resistor 7 is fixedly connected with an electromagnet 8 through the wire 3, the rear end of the electromagnet 8 is fixedly installed with the back of the armchair 1, a fixing piece 10 is fixedly installed at two thirds of the position of the fixing rod 9, mainly in order to ensure that the movable rod 11 can move enough, the electromagnet 8 is made of a coil and a metal block, two symmetrical fixing rods 9 are fixedly installed at the right side of the electromagnet 8, the two symmetrical fixing rods 9 are horn-shaped, the opening at the left end is small, the opening at the right end is large, the stability between the electromagnet 8 and the headrest 14 is mainly kept, the fixing piece 10 is fixedly installed between the two fixing rods 9, the middle part of the fixing piece 10 is inserted with the two symmetrical movable rods 11, the middle part of the fixing piece 10 is provided with a movable hole matched with the movable rod 11, and the diameter of the movable hole is, a stop 12 is fixedly mounted at the left end of the movable rod 11, and two symmetrical marbles 13 are fixedly connected to the right side of the stop 12.

Use through the cooperation of dog 12 with marble 13, can effectively restrict the home range of movable rod 11, avoid the range of movable rod 11 right motion too big, finally not influenced by electromagnet 8's magnetic force, marble 13 can the effectual help movable rod 11 motion left, provides convenience for reseing of movable rod 11.

A back cushion 14 is lapped at the right end of the movable rod 11, the back cushion 14 is semicircular, the radian of the back cushion 14 is rightward bent, the back cushion 14 is made of rubber, and the back cushion 14 is embedded at the right side of the chair 1.

Because the train arrives about ten minutes before the station, can report once the place ahead and arrive the station, so movable rod 11, back cushion 14 uses with the cooperation of electro-magnet 8, when movable rod 11 side-to-side motion, can effectually strike back cushion 14, thereby strike people's neck, because people's neck subcutaneous fat is thinner, it is comparatively sensitive, when massaging people's neck, can also strike people, it prepares to get off the car to pick up the luggage ten minutes in advance about, it is short to avoid the train to arrive the stop time of standing, it is too late to pick up the luggage, if some passengers place ahead and arrive the station and do not get off the car, also can strike the passenger, avoid getting off the car, the luggage is wrong or the thief takes off in disorder etc..

In use, when seated, a person's neck rests on the headrest 14.

When the power supply 2 is fully charged with USB, the fixed electrode 5 and the metal film 6 together form a capacitor by the capacitor being formed by two metal pieces that are close to each other, and when a voice is broadcast, the train arrives at a station ten minutes or so.

The metal film 6 is influenced by the voice broadcast in the train to generate vibration, because the train is generally quite quiet in the running process, only the voice broadcast sound of the train is relatively larger than some noise, so the metal film 6 is only influenced by the voice broadcast to vibrate, the distance between the metal film 6 and the fixed electrode 5 is changed, therefore, according to the capacitance formula, C ∈ S/4 pi kd, when other quantity is not changed, the distance of the distance d is changed, the capacitance formed by the fixed electrode 5 and the metal film 6 is changed, and therefore, the charge on the polar plate 4 is changed, namely, the circuit wire 3 generates audio current, and then the audio voltage is generated through the resistor 7, and because the audio current is not stable, the audio voltage is not stable, and therefore, the electrified electromagnet 8 is unstable in current and voltage, therefore, the magnetism generated by the electromagnet 8 is also small and large, so that the movable rod 11 made of iron is driven to reciprocate left and right, and people are reminded to arrive at a station while the neck of the people is knocked to massage.

Where C denotes capacitance, e is a dielectric constant, each material has its own dielectric constant, and is constant, S is an area of the metal thin film 6 facing the

fixed electrode

5, 4 is an arabic numeral 4, and pi is a circumferential ratio of 3.14 … …, and d is a distance between the metal thin film 6 and the fixed electrode 5.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
