Abstract
The utility model provides a kind of intercom under water, including for collection site environment voice signal sound pick-up, for the voice signal of collection to be amplified into the loudspeaker played out with the signal conditioning circuit of analog-to-digital conversion, the sonar communications set for being carried out subsurface communication using sound wave, the voice signal for that will receive；Wherein described sonar communications set includes emitter, receiver and transducer；Described sound pick-up is connected by signal conditioning circuit with emitter, and the receiver wireless connection that emitter passes through sound wave and other intercoms under water, the output end of receiver is connected by transducer with described loudspeaker.The utility model make use of the sonar communication transmission information between sonar communications set transmitter and receiver, diver under water operation when can directly carry out speech exchange, for the communication of diver provides guarantee, be conducive to smoothly completing for underwater operation, it is to avoid cause security incident.
Description
Technical field
The utility model is related to mobile communication technology, and in particular to a kind of intercom under water.
Background technology
Intercom is a kind of bidirectional mobile communication instrument, in the case where any network support is not needed, it is possible to converse,
There is no telephone expenses to produce, it is adaptable to be relatively fixed and frequently conversing occasion.When divers keep in touch under water, it will usually adopt
Use gesture exchange.During underwater operation, due to light problem and the problem of diver's notice, cause diver when facing a danger
It is difficult to and alarm, easily triggers security incident.For above-mentioned deficiency, the utility model provides one kind and carries out communication friendship under water
The intercom of stream, using the sonar communication transmission information between transmitter and receiver.
Utility model content
The technical problems to be solved in the utility model is：A kind of intercom under water is provided, for the communication of diver provides guarantor
Barrier, is conducive to smoothly completing for underwater operation.
The utility model is that the technical scheme that solution above-mentioned technical problem is taken is：A kind of intercom, its feature under water
It is：It includes：Sound pick-up for the voice signal of collection site environment, for the voice signal of collection to be amplified and
The signal conditioning circuit of analog-to-digital conversion, sonar communications set for carrying out subsurface communication using sound wave, for that will receive
The loudspeaker that voice signal is played out；Wherein
Described sonar communications set includes emitter, receiver and transducer；Described sound pick-up passes through signal condition
Circuit is connected with emitter, the receiver wireless connection that emitter passes through sound wave and other intercoms under water, the output of receiver
End is connected by transducer with described loudspeaker.
By such scheme, described sound pick-up and signal conditioning circuit is arranged in diver's helmet, and loudspeaker is arranged on latent
In the earphone that water person wears, sonar communications set is arranged on headband.
By such scheme, described signal conditioning circuit includes the amplifying circuit, filter circuit and the AD conversion that are sequentially connected
Circuit.
By such scheme, the opening angle of described loudspeaker is 5 ° to 30 °.
By such scheme, described transducer is piezo-electric crystal.
The beneficial effects of the utility model are：
1st, the sonar communication transmission information between sonar communications set transmitter and receiver is make use of, diver is under water
Speech exchange can be directly carried out during operation, for the communication of diver provides guarantee, is conducive to smoothly completing for underwater operation,
Avoid causing security incident；Sonar communication is more particularly suitable under water simultaneously, and stable performance substantially increases the quality of communication.
2nd, because the work of diver is special, intercom will be embedded into diving equipment under water, be more beneficial for diver's
Operation.
3rd, the opening angle to loudspeaker is further set, and may be such that transaudient effect is best.
Brief description of the drawings
Fig. 1 is the theory diagram of the embodiment of the utility model one.
Specific embodiment
With reference to instantiation and accompanying drawing, the utility model is described in further detail.
The utility model provides a kind of intercom under water, as shown in figure 1, it includes：For the sound of collection site environment
The sound pick-up of signal, for by the voice signal of collection be amplified with the signal conditioning circuit of analog-to-digital conversion, for utilizing sound
The loudspeaker that ripple carries out the sonar communications set of subsurface communication, the voice signal for that will receive is played out；It is wherein described
Sonar communications set include emitter, receiver and transducer；Described sound pick-up passes through signal conditioning circuit and emitter
Connection, the receiver wireless connection that emitter passes through sound wave and other intercoms under water, the output end of receiver passes through transducer
It is connected with described loudspeaker.
The minimum system that sound pick-up is made up of microphone and amplifier, vibrations are produced by collection site sound, are passed through
Amplifying circuit amplifies voice signal, by the signal being capable of identify that as sonar communications set after signal conditioning circuit, transmitting
Machine transmits the signal under water, is received by the receiver of other intercoms under water, and voice signal is converted to by transducer
Played by loudspeaker.
Preferably, described sound pick-up and signal conditioning circuit are arranged in diver's helmet, and loudspeaker is arranged on diver
In the earphone worn, sonar communications set is arranged on headband.
Preferably, described signal conditioning circuit includes the amplifying circuit, filter circuit and the A/D converter circuit that are sequentially connected.
Preferably, the opening angle of described loudspeaker is 5 ° to 30 °.
Preferably, described transducer is piezo-electric crystal.
The utility model uses high-performance sound pick-up, product embedded digital noise reduction and floating-point Phase Processing chip, can be most
The reduction noise of limits, reduces voice, it is adaptable to this environment higher to performance requirement under water.
Above example is merely to illustrate design philosophy of the present utility model and feature, in the art its object is to make
Technical staff will appreciate that content of the present utility model and implement according to this that protection domain of the present utility model is not limited to above-mentioned implementation
Example.So, equivalent variations or modification that principle, mentality of designing disclosed in all foundation the utility model are made, in this practicality
Within new protection domain.
