[Technical field to which the invention belongs]

 The present invention relates to a cradle with a hands-free handset function for a mobile phone that can be dialed with an external dialer, and is an external dial device that can be used for various mobile phones, which is convenient for a user, safe for driving and portable. Devices that increase the convenience of telephone calls.

[0002]

[Prior art]

 The most annoying thing about using a phone is finding a phone number, which is why a kind of dialer is prevalent. When the user wants to make a call, the user can use the dialer to enter the abbreviated number and dial the telephone number stored in the dialer in advance. The user simply places the dialer near the handset and uses it so that the handset can receive the DTMF voice generated by the dialer. Although such dialers are somewhat convenient for use, the convenience of these dialers has not been fully exploited in the current situation where mobile phones have become widespread. The main causes are as follows. 1. Since the DTMF decoder unit was not installed in the mobile phone, the mobile phone could not be activated and dialed by the DTMF voice in the dialer. 2. The dialer could not be used because the character codes of END, 0, 1, ... 9 are not the same.

[0003]

[Problems to be solved by the invention]

 In view of the fact that a known dialer was not usable for a mobile phone, the present invention provided a dial processing circuit in the cradle body with a hands-free handset function of the mobile phone and combined it with the use of the dialer. The task is to make it possible to use a dialer on a mobile phone and to dial from a mobile phone using the dialer.

Specifically, a main object of the present invention is to provide a cradle with a hands-free receiver function for a mobile phone that can be dialed with an external dialer, that is, a hands-free receiver function for a mobile phone. A dial processing circuit and related circuits are provided in the cradle to make it easier to use a mobile phone, and when dialing from a car with a mobile phone, dialing is performed using the dialer combined with the cradle with a hands-free handset function. It is an issue to improve the safety of driving by making it possible for the user to pick up the mobile phone and not to dial, and to make a call directly using the cradle with hands-free receiver after dialing is completed. I have.

[0005]

[Means for Solving the Problems]

 The invention of claim 1 is to provide a hands-free receiver circuit and a dial processing circuit in a cradle body with a hands-free receiver function, and a signal line and a dialer, that is, a DTMF sound generator, which is combined with the hands-free handset. In the cradle with a free handset function, the dial processing circuit includes a mobile phone dial decode IC or circuit, a dial control processing unit, a DTMF decode unit, and a control button, and the mobile phone dial decode IC or circuit decodes a dial code. The dial control processing unit is provided for controlling the dialing of the mobile phone when the dialer dials, and the DTMF decoding unit is provided for the dialing of the mobile phone. , DTM where dialers occur The F signal is decoded and converted into a dial code that can be received by a mobile phone through a mobile phone dial decode IC or circuit. The cradle has a speaker function. The invention according to claim 2 is characterized in that the dial processing circuit can be directly provided in one of the plugs at both ends of the signal line of the mobile phone, or can be accommodated in one case separately provided in the signal line. A cradle with a hands-free handset function for a mobile phone, which can be dialed with an external dialer according to claim 1.

[Embodiment of the invention]

 FIG. 1 is a block diagram of an embodiment of the present invention, in which a hands-free receiver circuit 11 and a dial processing circuit 12 are provided in a cradle body 1 with a hands-free receiver function, and a signal line 2 and a signal processing circuit 12 are provided. Dialer 3 (DTMF sound generator) is combined and formed.

The hands-free receiver circuit 11 includes a power supply and charging circuit 111, an amplifier and sound quality processing circuit 112, an audio signal control circuit 113, a microphone amplification circuit 114, a microphone 115, and a speaker 116 (or earphone). I have. The hands-free receiver circuit 11 is a circuit having the function of a general hands-free receiver and belongs to a well-known technique.

The dial processing circuit 12 includes a mobile phone dial decode IC or circuit 121, a dial control processing unit 122, a DTMF decode unit, and a control button 124, of which the mobile phone dial decode IC or circuit 121 receives an input signal. The mobile phone 4 decodes the dial code thus obtained into a dial code receivable by the mobile phone and provides the mobile phone 4 with a dial operation. The dial control processing unit 122 controls the dial input state of the mobile phone when the dialer 3 dials. The control button 124 activates the mobile phone and causes the cradle with hands-free handset to receive the DTMF signal. The DTMF decoding unit 12 decodes the DTMF signal generated by the dialer 3 and converts the DTMF signal into a dial code that can be received by the mobile phone 4 through the mobile phone decoding IC or the telephone 121.

The signal line 2 is a flexible wire body 21, one end of which is provided with a telegraph plug 22 inserted into a signal socket of the mobile phone 4, and the other end is inserted into a socket of a cradle having a hands-free handset function. A plug 23 is provided to connect the signals of the mobile phone 4 and the cradle 1 with a handsfree receiver function. Since the structure of the signal line is well known, detailed description is omitted.

The dialer 3 includes a DTMF sound generation unit and a storage unit therein, and the DTMF sound generation unit converts a telephone number in the storage unit into a DTMF code. The storage unit can store telephone data input by the user, and can be used for abbreviated dialing and later use (detailed description is omitted because the structure of the dialer is well known).

When the user wants to dial with the mobile phone 4 and presses the control button 124 connected to the cradle 1 with a hands-free receiver function, the dial control processing unit 122 of the cradle 1 with a hands-free receiver function is formed according to the above requirements. Activate the dialer 3 and directly enter the abbreviated number or voice input using the dialer 3, and place the dialer 3 near the input end of the cradle 1 with a hands-free handset function. After the dialer 3 searches for the telephone number to be recorded (this telephone number is input by the user in advance), the telephone number is converted into a DTMF code and output, and the cradle 1 with a hands-free handset function is used. Upon receiving this DTMF code, the DTMF decoding unit 123 of the dial processing circuit 12 starts decoding, the dial control processing unit 122 activates the mobile phone 4, puts it into a dial standby state, and sets the DTMF decoding unit. After completion of the decoding, the mobile phone dial decoding IC or circuit 121 starts dialing and connects the telephone to the other party.

In addition, as shown in FIGS. 2 and 3, the style of the mobile phone 4 is steadily increasing, and a single cradle with a hands-free handset function is applied to each type of mobile phone 4. For this reason, we provide the dial processing circuit 12 directly at any one of the plugs 22 and 23 at both ends of the signal line 2 or by providing one case 24 between the two plugs 22 and 23. This is the second embodiment of the present invention.

[0013]

[Effect of the invention]

 Taken together, the structure of the present invention is simple and convenient to use, and can be applied to various mobile phones, cradle and dialer with hands-free receiver function, and purchase a new mobile phone, cradle with hands-free receiver function and dialer. There is no need for it, and it completely solves the drawback that the well-known dialer could not be used in combination with a mobile phone.
