Abstract

The utility model discloses a small telephone, which comprises a shell body, a keyboard, a telephonic communication circuit and an earpiece. The small telephone is characterized in that the earpiece is in the size of an earplug, a high-speed electronic change-over switch is crossed over between the signal lines of a loudspeaker and a microphone for quickly alternately switching the signals of the loudspeaker and the microphone. The utility model has small size and convenient use; the small telephone can have various decorative models.

Description

Small telephone

The utility model relates to a kind of microtelephone, particularly relates to a kind of microtelephone that does not have traditional telephone receiver.

The telephone set (see figure 3) of present prior art, it comprises the telephonic communication circuit 40 that housing 10, keyboard 20, receiver 30 are established in reaching.The overall structure of this telephone set, because receiver 30 wherein, at least to make the distance of receiving

words portion

31 and 32 in the portion of passing on a message be the distance between common people's mouthful ear, housing 10 must cooperate putting of above-mentioned receiver 30 to put again, therefore the moulded of telephone set of prior art can't significantly dwindle, also difficulty has significant breakthrough on moulded, makes the market competition of this product very difficult.In addition, must often grip the receiver 30 of above-mentioned heaviness in use, use very inconvenience.

The telephone set of above-mentioned prior art is on moulded and volume, because of the restriction that is subjected to receiver can't have breakthrough development.Again in use, this telephone set must grip receiver for a long time and bring inconvenience.In order to overcome above-mentioned defective, the utility model provides a kind of brand-new microtelephone.

Main purpose of the present utility model is, a kind of microtelephone is provided, and dwindles the wherein volume of receiver, thereby bigger space design is arranged.

Another purpose of the present utility model is, a kind of microtelephone is provided, and receiver wherein is the earplug size, can overcome the inconvenience of long-time gripping receiver, and this receiver is hidden among the housing of this telephone set.

Another purpose of the present utility model is, a kind of microtelephone is provided, and is the ornament of a fineness when not using usually.

In order to achieve the above object, the utility model provides a kind of microtelephone, it includes housing, keyboard, telephonic communication circuit and receiver, it is characterized in that: said receiver is the earplug size, the microphone that is used for receiving the loud speaker of words and is used to give orders or instructions is located at same earplug, high-velocity electrons diverter switch of cross-over connection between the holding wire of loud speaker and microphone is used for alternately switching apace the signal of loud speaker and microphone.

The utility model has the advantages that volume is little, easy to use, and various decorative models can be arranged.

Below by preferred embodiment and accompanying drawing microtelephone of the present utility model is elaborated.

Brief Description Of Drawings:

Fig. 1 is a three-dimensional combination figure of the present utility model.

Fig. 2 is the schematic diagram that high speed of the present utility model is switched loud speaker and microphone signal circuit.

Fig. 3 is the schematic diagram of the telephone set of prior art.

See also shown in Figure 1, a kind of microtelephone of the present utility model, it comprises housing 1, keyboard 2, telephonic communication circuit 3 and receiver 4, above-mentioned keyboard 2 is identical with prior art constructions with telephonic communication circuit 3 grades.Of the present utility model being characterised in that, said receiver 4 is designed to be earplug size and shape, thereby the receiver volume of prior art is contracted to minimum, and then has the maximum space of shape-designing.

Please consult shown in Figure 2 again, the utility model will be used for receiving the loud speaker 5 of words and the microphone 6 that is used to give orders or instructions is located at same receiver 4, and between the holding wire of this loud speaker 5 and microphone 6 cross-over connection one high-velocity electrons diverter switch 7, be used for alternately switching fast the signal of loud speaker 5 and microphone 6, the situation that this device is in forever only have a kind of signal of communication to be connected, thus loud speaker 5 and microphone 6 eliminated because of interference phenomenon that hypotelorism produced.

Among the embodiment of the present utility model, housing 1 is designed to a kind of animal-shaped (as shown in Figure 1), wherein receiver 4 usefulness one extended line connects the afterbody that is arranged on this animal housing 1 rear, and have automatic wire winding function, can when not using, this receiver 4 be collected in (as shown in Figure 1) on the housing 1 automatically.Because receiver 4 of the present utility model is so little, and can be hidden on the housing 1, thereby broken through the restriction of functional moulding of the telephone receiver of prior art fully, the utlity model has bigger shape-designing space, can become a kind of desktop pendulum decorations articles for use of fineness, improve the value of this product.Present embodiment available double faced adhesive tape 9 or other analogs between the bottom surface of housing 1 and the table top 8 that bears are fixed, and make it more practical.

In sum, microtelephone of the present utility model because to the improvement of wherein earphone structure, makes little, the functional diversities of volume of the present utility model, and can exempt the inconvenience of hand-held receiver, has novelty and practicality really.

Claims

1, a kind of microtelephone, it comprises housing, keyboard, telephonic communication circuit and receiver, it is characterized in that: said receiver is the earplug size, loud speaker wherein and microphone are in same earplug, and one of cross-over connection is used for alternately switching fast the high-velocity electrons diverter switch of the signal of loud speaker and microphone between the holding wire of this loud speaker and microphone.
