Description

Amplifier for mobile phone.

The present invention relates to an amplification device for a mobile communication phone, and more particularly, to an amplification device capable of amplifying a transmission and reception signal of a mobile communication phone so that calls can be made even in a hearing loss area.

BACKGROUND OF THE INVENTION [0002] Cellular telephones include cellular phones, commonly referred to as cellular phones, and so-called PCS phones, abbreviated as personal communication services.

In the case of cellular phones, the analog frequency method is used initially, but the digital frequency method is used in recent years, but it has only the possibility of making a telephone call while moving. In the case of fish phone, voice service, various data transmission as well as image are available. Evolved into a multimedia that can be delivered.

However, both of them depend on the relay base stations installed in each region to transmit and receive radio waves for the call, and although these base stations are set up in place, a hearing loss zone is generated.

These hearing loss areas are not affected by radio waves transmitted and received from base stations in islands, mountainous areas, and interiors of buildings and vehicles (especially basements) where cars are running at high speeds.

As described above, some users use the amplification antenna on the back of the mobile communication phone for smooth passage in the hearing loss area, but the effect is insufficient.

As a result, restrictions on the use of mobile phones in books, mountainous areas, vehicles while driving, and basements increase user dissatisfaction, and in fact, call quality deteriorates in contrast to high-quality mobile phones desired by consumers. Have problems such as

Therefore, the present invention has been made to solve the above problems, by providing a small amplification device that can amplify the signal used in the transmission and reception of the mobile communication phone to improve the call quality in the hearing loss area. For the purpose.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation of the present invention for achieving the above object.

1 is a block diagram showing the configuration of the present invention, Figure 2 will be described together as a perspective view showing an embodiment of the present invention.

The amplification apparatus 10 of the present invention is capable of a normal transmission and reception state of the antenna 12 and the signal detected by the antenna 12 to detect the transmission and reception signals of the mobile phone in a casing 11 of the compact box type. The amplifier 13 is amplified so as to improve the call quality in the hearing loss area.

The amplifier 13 receives the main power from a power source means E, such as a general power source or a cigar jack of a car, and has a power source and a signal line 15 that can be connected to the mobile telephone 14. In the case of using 10), the main power of the amplifying device 10 is used instead of the battery power of the mobile phone 14.

In the casing 11 of the amplifying apparatus 10, in addition to the amplifier 13 for signal amplification, a signal controller (lever; 20) for maintaining an optimal transmission and reception state by appropriately adjusting the transmission and reception signals according to the degree of hearing loss. And amplification device 10 and charging equipment having an integrated speaker 21 capable of charging the battery 21 of the mobile phone 14 and the speaker 21 which can be talked without lifting the mobile phone 14. There should be no inconvenience to be provided separately.

The charger 23 has a confirmation lamp 24 for checking the state of charge and a discharge button 25 for forcibly discharging the voltage remaining on the battery 22 to charge the battery 22. ) Is further provided.

The present invention as described above is installed in the interior of a car or a general home and office so that power is supplied to the amplification device 10 using a general power source and a cigar jack, and the power and signal lines 15 drawn from the amplifier 13. Connect and use the mobile phone (14) through.

In the above state, the transmission and reception signal is detected by the antenna 12 connected to the amplifier 14, and the signal is amplified to the state in which the amplifier 13 can normally transmit and receive. Becomes possible.

In addition, an additional device such as a signal controller 20, a charger 23, and a speaker 21 is further provided in the amplifying device 10 to adjust the signal controller 20 according to the degree of hearing loss, thereby controlling transmission and reception states. It can be controlled, and the call can be made without carrying the mobile telephone 14 directly.

Then, the auxiliary battery 22 of the mobile telephone 14 can be charged by the charger 23 integrally provided on the casing 11 of the amplifying apparatus 10, and in particular, the process of charging the battery 22. The discharge button 25 can be used to help extend the life of the battery 22 by forcibly discharging and dissipating the voltage remaining in the battery 22.

The present invention as described above can be installed in an area where a radio wave is weak in the interior of a car or a building, making it possible to make a smooth (normal) call, thereby relieving the dissatisfaction of the mobile phone user and contributing to the improvement of the call quality. It can have such effects.
