The known prior art has the following problems to be solved.
As described above, a device that can recognize an incoming call of a mobile phone without having to wear the mobile phone is suitable for a case where it is not necessary to respond immediately when an incoming call is received or a case where a response cannot be made. For example, it may be useful to know whether there is an incoming call with a wristwatch or bracelet worn during a meeting. However, in this case, it is necessary to incorporate a receiver in a wristwatch or a bracelet and a transmitter in a mobile phone. In order to incorporate a transmitter into a mobile phone, it must be changed from the design of the mobile phone, which hinders the development of mobile phones that aim for further miniaturization. In addition, a dedicated receiver is required for each model, and there is a problem that the cost is high because there is no versatility. Furthermore, it is difficult to add the function to an existing mobile phone.

FIG. 3 is a connection diagram illustrating a transmitter of the apparatus according to the first embodiment. It is a connection diagram which shows the receiver of the apparatus of Example 1. FIG. 6 is a perspective view showing a modification of the vibration detection circuit 20. FIG. It is explanatory drawing of an incoming call notification signal.

  Hereinafter, embodiments of the present invention will be described in detail for each example.

FIG. 1 is a perspective view showing a mobile phone call notification device 10 according to the first embodiment.
As shown in the figure, the apparatus of the present invention can be easily mounted and used on any type of cellular phone 12. The transmitter 14 is fixed to the mobile phone 12 using, for example, a fixing tool 18 such as a band. The transmitter 14 may be integrated with a case (not shown) for housing the mobile phone 12. The connection of the electric wire etc. between the mobile telephone 12 and the transmitter 14 is unnecessary. Accordingly, the mobile phone 12 can be used as it is.

  A cellular phone 12 as shown in the figure is placed in a suitcase (not shown), for example, and the user secures the receiver 16 to the watch 50 by putting the watch 50 on his / her arm, for example. The mobile phone 12 is set to a silent mode in which no ring tone sounds and is set to vibrate when an incoming call is received. The so-called vibration function is attached to any existing mobile phone. The transmitter 14 detects this vibration and transmits an incoming call notification signal 19 to the receiver 16. When receiving the incoming call notification signal 19, the receiver 16 vibrates, for example, with a vibrator and notifies the user of the incoming call. When the user knows that there is an incoming call, the user then takes out the mobile phone 12 from the suitcase at an appropriate time and looks at the incoming call history. Then, if necessary, call the called party.

FIG. 2 is a connection diagram illustrating the transmitter of the apparatus according to the first embodiment.
As shown in the figure, the transmitter 14 includes a vibration detection circuit 20 that detects vibration at the time of incoming call of a mobile phone, an incoming notification signal transmission circuit 22 that is activated by a detection signal output from the vibration detection circuit 20, and a transmission antenna 38. . The vibration detection circuit 20 includes, for example, a resonator 28 that resonates with an incoming vibration of a mobile phone, an induction coil 30 integrated with the resonator 28, and a magnet that forms a magnetic field that penetrates the induction coil 30. . The output terminal of the induction coil 30 includes a rectifier circuit 34 that converts an induced current into a direct current, and a capacitor 36 that receives and accumulates the induced current.

  The resonator 28 is a substrate supported so as to be able to mechanically vibrate inside the case of the transmitter 14. In this embodiment, the magnet 32 is fixed to the case inner wall of the transmitter 14. When the resonator 28 vibrates and the induction coil 30 vibrates with it, the magnetic flux penetrating the induction coil 30 changes and an induced electromotive force is generated. Since the induced current flowing through the induction coil 30 is an alternating current, it is rectified to charge the capacitor 36. When the resonator 28 is set to have the maximum amplitude at the vibration frequency of the vibrator of the mobile phone, the vibration detection sensitivity is maximized.

  The terminal voltage of the capacitor 36 increases due to charging. For example, the incoming call notification signal transmission circuit 22 is a circuit that, when the terminal voltage of the capacitor 36 exceeds the breakdown voltage, causes the capacitor 36 to be discharged at a stroke and triggers the incoming call notification signal 19. In a mobile phone, the time for which the vibration continues is different between when an e-mail is received and when a call is received. As described above, when the vibration energy is converted into electric power and the incoming call notification signal transmission circuit 22 is activated when the electric power is accumulated more than a certain level, the incoming call notification is performed only when the vibration continues for a certain amount or more. Can be sent.

  The incoming notification signal transmission circuit 22 may be configured by, for example, a one-shot multivibrator so as to transmit the incoming notification signal 19 for several seconds after detection of an incoming call. Since the vibration energy of the mobile phone is converted into electric power and stored in the capacitor 36, if the incoming call notification signal transmission circuit 22 can be driven by this energy, no other power source is required. However, if the transmission power is insufficient, a battery may be connected in parallel with the capacitor 36.

FIG. 3 is a connection diagram illustrating the receiver of the apparatus according to the first embodiment.
The receiver 16 includes a receiving antenna 40, a receiving circuit 24, a switching element 44, a charging circuit 42, a backflow prevention diode 46, a notification device 26, and a battery 48. The incoming call notification signal 19 preferably has a unique signal pattern as much as possible to prevent interference, as will be described later. The receiving circuit 24 has a function of distinguishing and identifying this incoming notification signal 19 from that of other transmitters.

  When the incoming notification signal 19 is received, the output signal of the receiving circuit 24 has a function of switching the switch of the switching element 44 from the off state to the on state. The battery 48 is for driving the alarm 26. When the switching element 44 is turned on, power is supplied from the battery 48, and the alarm 26 is activated to drive, for example, a vibrator (not shown). A vibrator for a known mobile phone may be used. Since the total weight of the receiver 16 is light, even if a piezoelectric element is used, mechanical vibration felt by a person can be generated. Further, the alarm 26 may be an acoustic vibrator that emits a minute sound. Further, it may be a light emitting element such as an LED.

  Note that the charging circuit 42 has a function of charging the battery 48 for driving the receiver 16 by, for example, generating electric power with external light. The receiver 16 is easy to receive natural light because it is worn by a person. If this is used for charging, battery replacement becomes unnecessary. The battery 48 may be a capacitor or a rechargeable secondary battery. Further, the charging circuit 42 may detect the swing of the receiver 16 to generate power and charge the battery 48. The vibration detection circuit described with reference to FIG. 2 also has a function of generating power by swinging, but various known generators can be used as the charging circuit 42. This is suitable when the receiver 16 is carried in a pocket.

FIG. 4 is a perspective view showing a modification of the vibration detection circuit 20.
The illustrated vibration detection circuit 20 includes an induction coil 30 fixed to a case of a transmitter 14 (not shown) and a magnet 32 supported in the case. The magnet 32 is supported in the case via, for example, a spring 52. The resonator 28 includes a spring 52 and an adjustment screw 54. The adjusting screw 54 can be turned from the outside of the case using a screwdriver or the like. When the adjustment screw 54 is turned, the compression length of the spring 52 can be adjusted, so that the resonance vibration frequency can be finely adjusted. It can be adjusted to vibrate with optimum sensitivity to the vibration of your mobile phone.

FIG. 5 is an explanatory diagram of an incoming call notification signal.
For example, the incoming call notification signal transmission circuit 22 is configured to transmit a unique incoming call notification signal 19 that is randomly set in advance for each device. The incoming notification signal transmission circuit 22 and the reception circuit 24 are sold in pairs. The incoming call notification signal 19 transmitted by the incoming call notification signal transmission circuit 22 can be received only by the reception circuit 24 paired in advance. If a device such as a SAW filter is used, such a transceiver can be manufactured. The same selective communication can be performed using a digital filter.

  As described above, according to the present invention, since the transmitter is not incorporated into the mobile phone, there is no need to modify the mobile phone and it does not depend on the model of the mobile phone. No electrical wiring is required for the transmitter. In this way, the ultra-small receiver can be used by attaching it to various accessories such as a wristwatch, a bracelet, a hat, glasses, and a batch.
