Description

The cordless phone which provides the main body and the handset in a separate form like a landline phone {THE CORDLESS PHONE WHICH IS SEPARATED ALIKE TELEPHONE}

Field of invention

The present invention relates to a wireless telephone that can maximize the convenience of use by configuring the handset-type wireless telephone to separate the receiver and the main body like a current wired telephone by a coil cord, so that the wired telephone can be used as a wireless telephone. Although the device was designed by the present inventors (Utility Model Publication No. 94-1178), it was provided in the form of an adapter attached to a landline telephone, there were many restrictions on the implementation.

This can be improved and implemented in the landline phone itself to achieve the desired purpose as well as to provide more convenient. Providing a handset-type cordless phone in the form of a landline phone with a coil cord is placed in the reception set of the office and home. The present invention has been made in that the inconvenience to solve the inconvenience, the dial keyboard can be enlarged to make it easier for older people to use and design a variety of products.

Background of the invention

With the development of technology, wireless telephones, which are widely used, provide convenience to life. Currently, products that can be used by connecting multiple handsets to one main body have been developed to maximize convenience for the whole family. However, since the radiotelephone integrates all functions into the handset and is gradually miniaturized and lightened, it is inadequate to be placed on the reception set of an office or home.

In addition, due to the miniaturization of the phone, the size of the dial button is small, making it difficult for older people to press the dial, so the dialing keypad must be as large as current landline phones. There is a problem in that it is easily discharged using a rechargeable battery, and to solve this problem, a high capacity battery has to be provided, which is limited in size and weight to be applied to the current handset type, and ultimately, the handset is separated by a coil cord like a landline telephone. It must be provided in the form.

There are various forms of a method for providing a cordless telephone in the form of a wired telephone filed by the present inventor (utility model application 91-3315) and published (utility model notification 94-1178). First, cut the connecting line between the telephone trunk line and the main body of the telephone and attach the transceiver. Second, cut the connecting line between the telephone main body and the handset and attach the transceiver. There is a method of attaching a transceiver to the subdivision. Applicant No. 91-3315, filed by the inventor of the present invention, uses a first method, and an adapter including a bell signal detector, a directional separator, a wireless transceiver, and a call circuit detector is provided on a wall surface. An adapter including a bell signal generator, a directional separator, a wireless transceiver, and a hook switch detector is fixed to the telephone body and wirelessly connected, but the circuit is complicated and the size of the adapter device is unreasonable.

The second method is the 94-1178 of the present application, which is used in ordinary radiotelephones. The main body of the radiotelephone minimizes the functions by the transmission / reception circuit, the relay, the password setting, and the retrieval function. It is characterized by setting the on / off switch.

* Purpose of invention

The object of the present invention is that, despite the convenient advantages of using a conventional handset type wireless telephone, it is difficult to install by position and wiring due to the power supply line and telephone line when the main body of the telephone is placed on the reception set, and the handset is placed on the reception set. There is a problem in that it is not suitable for stability and functionality.

In addition, there are many cases where the user receives a phone call while using a speakerphone. However, in the present handset type wireless telephone, such a speakerphone function is not provided. However, the present invention provides a more convenient phone culture by providing such a function. Purpose.

As the society ages, the aging population is increasing. Most of the aging population are unable to remember where they have been placed after use due to memory loss and poor vision. To solve this problem, to solve this problem, the portability of the cordless telephone is somewhat sacrificed by configuring it as a wire telephone as in the present invention. It is possible to apply a high capacity battery can be configured to enable even if not frequently charged.

Summary of the invention

The present invention relates to a wireless telephone having a main body and a handset connected to a coil cord like a wired telephone. The telephone line includes a main body comprising a wireless transmission / reception circuit, a telephone control device, and a ringtone processing circuit, and corresponding counterpart wireless. The present handset consists of a radio transmitter and receiver circuit, a control circuit, a receiver sensing circuit, a spurphone circuit, a battery, a coil cord and a speaker, and a microphone so that the telephone is provided in a form separated from the coil cord by the receiver and the main body like a current wire telephone. The mobile phone is used as a mobile phone and is configured to receive a speakerphone when receiving a call while working. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Detailed description of the invention

The cordless telephone provided with the main body and the handset separated by a line like the wired telephone of the present invention has a characteristic that is convenient for carrying and talking while the current handset type cordless telephone is portable, but it is not suitable for human conscious living. The solution focuses on the advantages of large dials, high capacity batteries, and arbitrarily fixed phone installation locations that are difficult to provide with handsets in the way of providing cordless telephones in the form of conventional landline telephones. It is characterized in that it can provide a speakerphone function that is not implemented in a handset-type wireless telephone.

Transceiver circuits of radiotelephones are largely divided into analog and digital methods, and each channel is selectively configured to select the cleanest channel under the control of the central controller, and the frequency band is changed from 40Mhz to 900Mhz recently. It is a trend that uses up to giga band, and it is difficult to predict the future phone image because technology that introduces outgoing concept of wireless telephone and combines with outgoing telephone and various mobile phones is introduced.

Due to the development of wireless transmission and reception circuits and semiconductor technology, the existing complex transmission and reception circuits are connected to a small number of accessory parts around the one chip, and the signal processing stage reaches a stage. The technology is expected to be developed to create new functions and technologies using these devices.

As a wireless telephone is a product of human need for more convenience, telephone related technologies will be advanced in order to solve the current problems functionally and technically, and the present invention is also a technology proposed in response to such advances, The present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic diagram of a wireless telephone in which the main body and the receiver are provided in a form separated by lines, such as a wire telephone according to the present invention.
