 The gist of the present invention is that the mobile phone strap is equipped with a tuning circuit for tuning to the transmission / reception carrier of the mobile phone, and a liquid crystal display means driven by the output of the tuning circuit. A display device for displaying desired display information on the liquid crystal surface by the liquid crystal display means.

[0006] A mobile phone to which the present invention is applied is a device that performs wireless communication, and includes all wireless devices that perform communication using high-frequency transmission / reception carrier waves. A mobile phone is equipped with an antenna rod, which is an antenna means for receiving or transmitting a predetermined radio wave, and is usually adjustable in length to enhance a tuning effect.

[0007] A strap provided on the mobile phone includes a tuning circuit including an LC resonance circuit for generating a DC voltage in synchronization with a transmission / reception carrier of the mobile phone, and a DC voltage generated by the tuning circuit as driving power. It is equipped with a liquid crystal display that operates. Further, the liquid crystal display means is usually provided with an expression means for transmitting desired display information.

[0008] The tuning circuit is preferably provided on a printed circuit board, and a rectifying diode is connected to a coil that is electromagnetically coupled to a transmission / reception carrier of a mobile phone to generate a DC voltage. Also, a conductor (antenna pickup) surrounding the base of the antenna rod of the mobile phone may be provided in the tuning circuit. When provided on a printed circuit board, a printed circuit board on which an ordinary electric circuit is printed may be cut into small chips. It is desirable that the printed circuit board and the antenna rod be electrically insulated.

More specifically, it may be a normal coil component or a pattern-printed coil. In this case, it is desirable to print the coil on both sides of the substrate to gain gain. Also, the form of the coil to be printed is not particularly limited, but it is preferable to connect each of the front and back coils in a conductive state as a substantially planar wound coil.

A rectifying diode is connected to the coil, and a circuit of a liquid crystal display means and a circuit of an expression means for transmitting desired display information to the liquid crystal display means are connected to a subsequent stage. The liquid crystal display means is a so-called liquid crystal panel (LCD) that activates each liquid crystal element mounted on the panel by turning on / off a voltage. This liquid crystal panel is not particularly limited, and a suitable one may be selected and used. In addition, liquid crystal panels may be provided on both sides.

[0011] The presence or absence of a backlight provided in the liquid crystal panel is not particularly limited. If the backlight is not provided, a light emitting diode is provided after the rectifying diode, and the backlight of the liquid crystal panel is provided. It may be used as a light and / or a light emitting sign for incoming calls. The shape, color and number of the light emitting diodes are not particularly limited either, and may be any suitable number or number.

Alternatively, the liquid crystal display means and the expression means may be provided integrally, or they may be separately provided in a suitable portion. Specifically, the expression means may be provided on the printed circuit board at the attachment portion of the hand-held ring.

The expression means is a circuit composed of suitable electronic components for appropriately controlling the liquid crystal element of the liquid crystal display means and displaying desired information on the liquid crystal display means. The electronic means depends on the contents displayed on the liquid crystal display means. What is necessary is just to select the structure of components. Various sensors may be used as needed. As an example of a specific display, it is a display of characters, numbers, illustrations, initials, temperature, humidity, time, date, the number of calls, and the like. Furthermore, a simple microcomputer or the like in which various expression methods are assembled may be incorporated in the expression means, and the illustration displayed on the liquid crystal display means may be moved or the characters may be displayed in a flowing manner.

[0014] Further, a battery serving as a backup power supply for storing display information of the liquid crystal display means may be fixedly or exchangeably provided to back up the display information. Further, an electronic component may be provided in the circuit as appropriate so that the battery can be charged when the circuit is operated. Fixed means that the battery is incorporated as a part of the circuit so that it cannot be separated, and replaceable means that the battery inside can be replaced when the battery is exhausted. The interior position of the battery is not particularly limited.

[0015] The mode of mounting the tuning circuit and the liquid crystal display means on the strap is not particularly limited, but as a specific mode of mounting, the tuning circuit is provided on the attachment portion of the hand strap ring. The liquid crystal display means may be provided near the tip of the strap. Further, the tuning circuit and the liquid crystal display means may be integrally formed, and the diameter of the strap body of the strap may be provided so as to be adjustable.

[0016]

[Action]

 Since the strap of the present invention is configured as described above, if the mobile phone is in the transmitting / receiving state, a voltage is generated on the antenna rod, and the coil on the print substrate that is electromagnetically coupled to the antenna rod is excited.

In the case where the light emitting diode is provided, the voltage is supplied to the light emitting diode and the light emitting diode is turned on.

The liquid crystal display means and the expression means receive the voltage, and the liquid crystal display means serves as a power supply for turning on / off each liquid crystal element. The expression means sends desired display information to the liquid crystal display means, The element is controlled to display information on the liquid crystal display. In the case of a device having a microcomputer, the displayed information is moved so that the illustration moves or characters are displayed.
