Abstract

The utility model relates to a simplex wireless movable communication telephone, which changes the mode of present sound receiver arranged on one end of a telephone into the mode of a sound receiver arranged on two ends of the casing of a telephone. Conversion can be sent out without the move of a telephone and the sound receiver can close to the ear of a user when the utility model is used. The utility model has the advantages of convenient operation, enhanced conversation speed and reliable performance.

Description

Simplex wireless movable communication telephone

The utility model relates to a kind of mobile communication phone machine, more specifically, relates to a kind of simplex radio mobile communication phone machine.

The transmitter and the receiver of existing simplex radio mobile communication phone machine lean on nearerly, place the same end of telephone set usually.Need when the user send words the close user mouth of transmitter, receiver then sends the big sound, and the user can be heard.In the middle of the bigger construction site of the extraneous sound, road (as traffic police etc.) is also applicable for this using method, but in many cases, because the huge sound of receiver brings very big interference to other people, also know dialog context because of what the people around at the scene can both hear information that receiver sends and user with ining a minute, this be in many cases extremely inconvenience or user loth.Though can solve this problem and receiver placed in one's ear and reduce volume, again must mobile phone when the user send words, make transmitter near the mouth, this makes troubles again.And mobile phone must cause the discontinuous of conversation, and conversation speed is reduced, and reliability also reduces, and this is not to use the person to wish to be avoided naturally.

The purpose of this utility model provides a kind of novel simplex radio mobile communication phone machine, and this phone function allows the user needn't mobile phone and send and be subjected to the words operation.Another purpose of the present utility model is to make the battery of above-mentioned telephone set and transmitter easily disassemble and to install with the telephone set remainder, makes the charging of battery and telephone set use very convenient.

For achieving the above object, telephone set of the present utility model comprises shell, transmits and receives circuit, transmits and receives conversion equipment, display unit, keyboard, antenna, battery, electrophone, it is characterized in that described electrophone places the two ends of described shell respectively.More and then, the transmitter of this telephone set and battery are the dismountable parts as telephone set, and remainder is as dismountable another part, each is connected these two parts with a connector that matches.

Fig. 1 is the front view of present simplex radio mobile communication phone machine;

Fig. 2 is the front view of the telephone set of an embodiment of the present utility model;

Fig. 3 is the view of the telephone set the first half of separating of the A-A line from Fig. 2;

Fig. 4 is the view of the telephone set the latter half of separating of the A-A line from Fig. 2.

Fig. 1 is the front view of present simplex radio mobile communication phone machine.6 is receivers, the 7th among the figure, transmitter.As can be seen, electrophone is to be close together among the figure, and all above telephone set.

Among Fig. 2, display unit 12, keyboard 13, antenna 14, receiver 15, emission receiving converter 16 and the not shown circuit that transmits and receives that is installed in the shell are housed on the shell 11.Battery (not shown) and transmitter 18 are housed in the latter half of shell 11.As seen from Figure 2, transmitter 18 is installed in the other end relative with receiver 15.Among the embodiment of the present utility model, two removable sections have been assembled after, electrophone towards with the one side.Because electrophone places the two ends of telephone set respectively, the user can place receiver in one's ear, and makes transmitter near mouth, and mobile phone again when sending the words operation has been removed many troubles from, and improved conversation speed.Because receiver is near in one's ear, volume needn't be very big, and except the user, other people do not know the content that both call sides is talked.The reducing and to realize by the gain that reduces cased audio amplifier circuit of volume.

From Fig. 3 and Fig. 4 as can be seen, the telephone set first half respectively has a pair of mechanical splice that becomes to work in

coordination

19 and 20 with the Lower Half interface, is used for making first half Lower Half easily to disassemble or is assembled together.When the stored electricity of the battery in the Lower Half uses, can take Lower Half apart, to battery charge, charging electricity can be reinstalled.Because joint has interchangeability, also can change the standby first half or Lower Half at any time.No matter which part parts has fault to need to change, or uses the reserve battery that has charged all very convenient.

Because telephone set is divided into dismountable two parts, also dismountable electrical connection arrangement must be set between two parts.As seen from Figure 4, two

electrical pickofves

21,22 are arranged on the Lower Half composition surface, be used for usefulness for the charging of battery.In an embodiment of the present utility model, one in these two electrical pickofves is earth point, can reduce electrical pickoff on circuit design, makes ground connection electric contact and another electric contact 23 constitute the path that is electrically connected of transmitter 18.Correspondingly, as shown in Figure 3,, also be provided with and the corresponding contact 24-26 of above-mentioned electrical pickoff, making when two parts are assembled together the operate as normal that guarantees the circuit each several part with the Lower Half place of matching at the first half of telephone set.These contacts can be adopted such as this mode of Elastic Contact, the excellent contact after guaranteeing to assemble.

Above-mentioned example is just realized a concrete instance of basic design of the present utility model, and design of the present utility model also not only is confined to the scope of this example.Can make some and change,, even only change the relative position etc. of each several part such as the position of adjusting electrophone.Basic design of the present utility model is not left in these changes, still belongs within the protection range of the present utility model.
