Description

Chinese character shows multi-function telephones number quickly dialing device

The utility model relates to a kind of multi-functional telephone number fast dialing device that is used for the dual tone phone machine, a kind of specifically Chinese character display electronics assemblies that integrates calculator, notepad, clock, calendar and phone number dial device.

At present, the program controlled telephone of the use overwhelming majority adopts the dual-tone dialing mode, and this dial mode error rate is low, and dialing rapidly.Particularly some telephone set has the telephone number memory function, for the user provides more quick and accurate dialing means.In recent years the inventor has invented telephone number fast dialing device and has applied for Chinese patent through research repeatedly, and the patent No. is ZL92233485.4, and telephone number fast dialing device provides a kind of quick device of calling again for the user.Yet it is convenient inadequately that this device also exists use; Memory space is little, and information memory capacity is not enough; Western language shows the people's use that is not suitable for using Chinese; Bigger the carrying of volume still shows inconvenience; The incomplete defective of cpu chip arithmetic speed low-function.The inventor has invented the utility model finally through further further investigation.

The purpose of this utility model is in order to overcome the defective that prior art exists, the multi-function telephones number quickly dialing device that provides a kind of follow-on Chinese character to show.

The utility model is to realize like this, it mainly comprises central processing unit, memory, data latches, the dual-tone dialing circuit, display, input keyboard, Microspeaker and shell, it is characterized in that central processing unit and memory, data latches are integrated in the special-purpose central processor unit of formation in the integrated circuit (IC) chip, wherein said memory comprises the program storage that stores monitoring program and the data storage of storaging user data, also comprises the library stores device of the storage Hanzi font library that is independent of outside the central processor unit; Display is included as the lattice liquid crystal display screen and the control drive unit that can show Chinese character, numeral; Special-purpose central processor unit links to each other with library stores device, keyboard, display and dual-tone dialing circuit respectively, and the audio signal output end of dual-tone dialing circuit connects Microspeaker.

Described shell comprises bottom, panel and over cap, and bottom and panel constitute housing, and over cap adopts flip structure, is connected with housing by rotating shaft, and the position that over cap is corresponding with the display screen of display is provided with form; Panel top button commonly used is exposed at outside the over cap.

Described Microspeaker is installed in the shell bottom, and the bottom relevant position is provided with through hole.

Advantage of the present utility model is, utilizes new integrated circuit to make volume smaller and more exquisite, is easy to carry more as notepad; Adopt Chinese character to show that use is convenient, be particularly suitable for the Chinese and use; The Microspeaker that employing is littler than prior art under the prerequisite of assurance function, makes outward appearance more attractive in appearance.

Below in conjunction with the most preferred embodiment in the accompanying drawing the utility model is further described.

Fig. 1 is circuit theory diagrams of the present utility model.

Fig. 2 is a profile panel front view of the present utility model.

As shown in Figure 1, the central processing unit in the utility model, memory, data latches etc. are integrated in the integrated circuit (IC) chip, constitute special-purpose central processor unit U1 (ZL9808).Wherein said memory comprises the program storage that stores monitoring program and the data storage of storaging user data, also comprises the library stores device U3 (SRAM) of the storage Hanzi font library that is independent of central processor unit U1.S1～S4, the S68～S74 of special-purpose central processor unit U1 links to each other with the keyboard battle array with K12～K16 end.Special-purpose central processor unit U1 also links to each other with library stores device U3, display lcd and dual-tone dialing circuit U 2 respectively.The corresponding audio signal of generation was exported to profile speaker RL successively after dual-tone dialing circuit U 2 (LR4088B) received dial data.Display lcd is the lattice liquid crystal display screen of large-screen, and it can show that promptly numeral can show Chinese character again.Comprise numerical key, character keys and function key in the input keyboard.

Also comprise some peripheral circuits in the utility model, as: power circuit, buzzer circuit ... or the like, these circuit structures and function all are the custom circuits in common calculator or the electronic notebook, give unnecessary details no longer one by one at this.

As shown in Figure 2, shell of the present utility model comprises bottom, panel 1 and over cap 2, and bottom and panel constitute housing.The printed circuit board (PCB) that integrated circuit is installed is installed in the housing, and the display screen of LCD is arranged on the panel 1, and Microspeaker is installed in the bottom, and the relevant position on the bottom is provided with the through hole (not shown), and is unobstructed so that sound transmits.

Over cap 2 adopts flip structures, is connected with housing by rotating shaft, and the position that over cap is corresponding with the display screen of display is provided with form 3, makes the demonstration that also can see display screen under the situation of not opening over cap.Part on the panel 1 button commonly used such as open and close key, dial key, conversion key, index buttons etc. are exposed at outside the over cap, can not finish so that do not open over cap when doing general operation, make that use is very convenient.

Chinese character of the present utility model shows multi-function telephones number quickly dialing device, except that the function with general calculator, clock, calendar, also has the function of notepad, address list, phone number dial device.The user can be pre-stored in hundreds of clients' telephone number in the machine, and the name searching that shows by Chinese character during use goes out telephone number corresponding, in order to consulting.Can push " dial key " after particularly consulting, send the pairing audio signal of telephone number the telephone set of dual-tone dialing to by loud speaker, telephone number be transferred to, to reach the purpose of accurately calling rapidly.Dial feature of the present utility model quick and precisely, can redial repeatedly, this be ordinary electronic notepad, address book can't realize.

Notepad function of the present utility model can be stored contents such as travel schedule, commemoration day, memorandum, owing to adopted the Chinese character demonstration, therefore points out effect more accurately to understand.The imputting Chinese characters of this device can be selected input methods such as phonetic or the Five-stroke Method, imports very flexiblely, is applicable to numerous users.

The utility model also has many other functions, and these functions and aforesaid patent application (92 2 33485.4) basically identical just increase at aspects such as performance, reliabilities.Not only the volume whole device of urinating is easy to carry as: the Microspeaker of use, and the distorted signals that produces is little, and the dialing accuracy rate has obtained improving widely.

Above-mentioned embodiment does not constitute the qualification to the utility model protection range.Those of ordinary skill in the art can carry out various changes in not exceeding the protection range that the utility model claims are limited.
