Problems solved by technology

[0002] At present, there are more and more mobile phone users in China. People usually save their contacts in their mobile phones. When users lose their mobile phones, they often lose all their contacts, which brings inconvenience to work and life.
[0003] Now there are some phone number backup devices on the market, which lack text interface operation prompts. Some backup devices have too small a capacity and need to be copied many times, which is inconvenient to operate. Moreover, the backup device is only for number backup. If you need to find a specific number, After being retrieved, it needs to be re-entered on other phones to dial. The actual use function is very limited and cannot meet the applicability requirements of mobile phone users.

Embodiment 1

[0051] see figure 2 , the audio dial module 3 can be connected to the phone through a wired method, the specific method is as follows:

[0052] a, the phone is off-hook, and the switching circuit 35 establishes the connection between the phone dialer and the phone outside line;

[0053] b. The user first finds the required phone number through the phone dialer, presses the send key or the prefix number send key, and the dual-tone multi-frequency circuit 31 converts the phone number into an audio dial signal and sends it to the outside line of the phone;

[0054] c. After the outside line of the phone is connected, the transfer circuit 35 automatically disconnects the outside line of the phone and the dual-tone multi-frequency circuit, and the outside line of the phone is automatically connected to the phone, and the phone starts talking, so as to realize automatic dialing without manual dialing.

Embodiment 2

[0056] see image 3 , the audio dialing module 3 can be connected to the phone in a wireless way, the specific way is as follows:

[0057] a. Off-hook the phone, and point the microphone of the phone to the speaker 32 of the phone number backup dialer;

[0058] b. The user first selects the desired phone number through the phone dialer, and presses the send button or the prefix number send button, then the audio dial signal can be amplified by the audio amplifier 37, and then the speaker 32 sends a sound wave signal to the phone microphone;

[0059] c. Through sound wave coupling, the outside line is directly connected to the number, and the phone starts talking, so as to realize the automatic dialing of the phone.

[0060] In the present invention, the mobile phone directory backup module and the audio dialing module are divided into multiple chips, and the external interface circuit of the mobile phone, the central processing unit, and the dual-tone multi-frequency circuit ...

Abstract

The invention provides a mobile telephone interface and dialing integration circuit and a telephone set dialing device applied to the same. The integration circuit comprises a mobile telephone external interface circuit, a dual-tone multi-frequency circuit, a memory and a central processing unit, wherein the central processing unit is respectively connected with the mobile telephone external interface circuit, the dual-tone multi-frequency circuit and the memory; the central processing unit leads telephone-number book information stored in a mobile telephone into the memory for storage by the mobile telephone external interface circuit; and the dual-tone multi-frequency circuit converts the telephone-number book information stored in the mobile telephone into an audio-frequency dialing signal. The invention also provides the telephone set dialing device applied to the mobile telephone interface and dialing integration circuit. The integration circuit and the telephone set dialing device can realize the functions of information backup and automatic dialing of a telephone-number book.
