Abstract
The utility model discloses an intercom with many PTT key, including interphone body and antenna, control circuit board, microphone and speaker, its characterized in that: the last predetermined a plurality of PTT keys of talkbacking of being used for of interphone body, every PTT key correspond different frequency, channel, number and key to be connected with control circuit board, such design, accessible control circuit board's connection is initiated to telephone to different users, the utility model discloses a modern design, it is fixed through predetermineeing the signal that corresponds the PPT key, need not make adjustment to the intercom during use, can communicate by fast settling, facilitate the use.
Description
Technical field
The utility model relates to electronics field, is specifically related to the intercom of a kind of improvement.
Background technology
Owing to intercom cluster is to instant intercommunication of making peace, use very convenient, and there is no the features such as Communications service expense, have
The biggest application prospect.But the most traditional intercom is all only to arrange single intercom push key (the Push i.e. PTT of to Talk
Button), there is certain use defect in such setting.Mainly, if it is desired to carry out other letter during intercommunication
Road communicates, and is to be inconvenient for troublesome, and user needs to carry out parameter setting again and adjustment, and once parameter is arranged
Improper, it is likely to result in situation about cannot communicate and occurs, add the complexity of operation.Therefore, prior art haves much room for improvement
And raising.
Utility model content
The purpose of this utility model be overcome above-mentioned the deficiencies in the prior art in place of, it is provided that a kind of intercommunication with many PTT key
Machine, can preset according to the requirement of user the parameter that each intercom push key is corresponding before using, is made without setting during use
Fixed, it is possible to realize i.e. taking i.e. use, convenient and swift.
The purpose of this utility model is achieved by the following technical solution: a kind of intercom with many PTT key, including
Intercom body and antenna, control circuit plate, microphone and loudspeaker, it is characterised in that: preset on intercom body
Multiple PTT keys for intercommunication, described each PTT key corresponding different frequency, channel, number and key, and with
Control circuit plate connects.
Further, each PTT key correspondence is configured with independent microphone and loudspeaker, they respectively with control circuit
Plate connects.
The described predeterminable different frequency of each PTT key, channel, number and key, by the company with control circuit plate
Connect and different user is initiated call.
Described PTT key has 2-12, and intercom body is provided with the back splint fixed for intercom body.
Compared with prior art, the beneficial effects of the utility model are:
1, by presetting each PTT key corresponding different frequency, channel, number and key etc., different user can be sent out
Play call, be not required to intercom is in use made setting and adjusts, simplify operating process, it is possible to fast run-up
Vertical communication, convenient use.
2, determine communication object by this default method, may be used for distinguishing the ditch between different stage user
Logical authority, it is to avoid cause confusion.
3, the utility model small product size is little, lightweight, it is possible to wear, and can liberate the both hands of user.
Accompanying drawing explanation
Fig. 1 is the schematic diagram in the utility model body front.
Fig. 2 is the schematic block circuit diagram of the utility model embodiment.
Description of reference numerals: 1 microphone；2 loudspeakers；3PTT key group；4 antennas；5 control circuit plates；31～
38 is corresponding PTT button.
In order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, below will to embodiment or
In description of the prior art, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only
It is embodiments more of the present utility model, for those of ordinary skill in the art, before not paying creative work
Put, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail so that advantage of the present utility model and
Feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clearly
Define.
Seeing Fig. 1 and Fig. 2, the intercom with many PTT key of the present embodiment, including on intercom body and body
PTT key group 3, intercom body is provided with microphone 1, loudspeaker 2, antenna 4 and control circuit plate 5.PTT key
Eight PTT buttons 31～38 that group 3 is preset are connected with control circuit plate 5 respectively, microphone 1, loudspeaker 2 and antenna
4 are connected with control circuit plate 5 respectively, described each PTT key according to preset can corresponding different frequency, channel, number
Code and key etc., can initiate call, the intercommunication of described many PTT key by the connection with control circuit plate 5 to different user
Machine also includes back splint, fixing for intercom body.
Operation principle and process: after opening intercom, enter holding state, now can carry out according to default channel parameter
Call.Such as, press PTT button 31, after control circuit plate 5 judges that PTT button 31 is pressed, be adjusted to it relative
The parameters such as the frequency answered and key, now enter intercommunication function, and microphone 1 picks up the sound of user, control circuit plate
Sent signal by antenna 4 after 5 process signals, receive via the interphone antenna 4 presetting parameter corresponding with PTT button 31
After corresponding transmitting voice signal processes to control circuit plate 5, loudspeaker 2 play, complete an intercommunication process.Press
Lower PTT button 33, then carry out another corresponding parameter intercommunication call such as the frequency organized and key, and so on, this reality
Execute in example one to have eight groups of different frequency parameters and be available for intercommunication call.
Each PTT key is according to presetting corresponding different frequency, channel, number and key, and certainly, each PTT key also may be used
Correspondence is configured with independent microphone and loudspeaker, and they are connected with control circuit plate 5 respectively, can by with control circuit
Different user is initiated call by the connection of plate 5, uses intercom of the present utility model, can be not required in use to right
The machine of saying is made setting and adjusts, and simplifies operating process.The utility model intercom volume is little, lightweight simultaneously, it is easy to
Wear, user's both hands can be liberated.By presetting, signal corresponding for PPT key is fixed, it can be ensured that communication process reliable.
Above specific embodiment of the utility model is described.It is to be appreciated that the utility model is not
Being confined to above-mentioned particular implementation, those skilled in the art can make various deformation within the scope of the claims
Or amendment, this has no effect on flesh and blood of the present utility model.
