Abstract
The invention discloses an interphone, comprising a body, and a power supply, an intercom module, a microphone, a loudspeaker and an audio signal processing unit, which are installed on the body, wherein the power supply supplies power to the interphone, the microphone is used for collecting a voice signal and transmitting the collected voice signal to the audio signal processing unit, the audio signal processing unit comprises an audio encoding and decoding module, a wireless communication module and a radio frequency module, the audio encoding and decoding module encodes and compresses the voice signal collected by the microphone, and the wireless communication module sends the encoded and compressed audio data to the loudspeaker through the radio frequency module. The interphone has the advantages of low power consumption, high integration, strong anti-interference ability, stable radio frequency signal transmission, long transmission distance, good input and output tone quality, high transmission efficiency and small volume, and thus the working efficiency can be obviously improved. The data are transmitted by a wireless network, and large-range and remote wireless data communication can be achieved. The transmission distance can reach 200n, and preferably, the transmission distance is 25-75m.
Description
Technical field
The invention belongs to audio frequency technical field, it is specifically related to a kind of interphone.
Background technology
Traditional interphone is a kind of portable two-way radio transceivers, main feature is half-duplex operation passage and presses button and just can transmit, and traditional interphone is when without any need for network support, just can converse, telephone expenses are not had to produce, being applicable to the occasion relatively fixed and frequently converse, as the important tool of short-distance communication and mobile scheduling commander, in society, industry-by-industry is all widely used. especially along with the development of digital circuit technique, the analog-interphone relatively traditional in external form or performance of novel interphone has all had significant progress, the signal disturbing of interphone and transmission range are maximum difficult problems for interphone systematic study always, traditional interphone only can realize intercommunication function, mainly as between member of community among a small circle communication exchange instrument, realize short-range wireless communication function, existence and stability is poor, it is subject to noise jamming, the shortcoming that transmission range is short, and cost of manufacture is relatively high, the use seriously hindering interphone is promoted. interphone in existing market cannot obtain rescue information in time when generation disaster, and meanwhile, if when carrying out microcommunity activity, interphone cannot use as speaker, in addition, relatively far apart, or when centre has high-lager building or high mountain to stop, speech quality can be greatly affected the distance between two interphones.
Along with the intellectuality of mobile terminal, more and more peripheral hardwares needs to communicate with mobile terminal, selects audio port to be one as data channel and well selects, because the mobile terminals such as mobile phone all support 3.5mm headset plug. Current peripheral hardware signal is all transmit with simulating signal by audio port, peripheral hardware master chip converts numerary signal to simulating signal by digital-to-analog conversion, mobile terminal is delivered to by Mike (MIC) oral instructions, signal is carried out analog to digital conversion by mobile terminal, and simulating signal is reduced into numerary signal. Its Problems existing is the intercommunication function that mobile terminal cannot realize between terminal and terminal when disconnecting networked environment, causes the problem of the decline of mobile terminal service efficiency, not yet proposes effective solution at present.
Audio frequency interface can only be supported and gather simulating signal, cannot directly support and gather numerary signal.
Summary of the invention
For the technical problem existed in prior art, it is an object of the invention to provide that a kind of cost of manufacture is low, stable performance, long transmission distance wireless interspeaker system.
In order to realize above object, the present invention is achieved through the following technical solutions.
A kind of interphone, comprise fuselage, with the power supply installed on fuselage, intercommunication module, microphone, loud speaker and audio signal processing unit, described power supply is that interphone is powered, described microphone is for gathering speech signal, and the speech signal of collection is sent to audio signal processing unit, described audio signal processing unit comprises audio frequency coding/decoding module and radio communication module and radio frequency module, the speech signal of microphone collection is carried out encoding compression processing by described audio frequency coding/decoding module, audio frequency data after encoding compression processing are sent to loud speaker by radio frequency module by described radio communication module, the audio input end of described intercommunication module is electrically connected with audio frequency coding/decoding module, the audio output of intercommunication module is set up with radio frequency module and is electrically connected, intercommunication module is electrically connected with antenna end.
Further, described fuselage side is provided with hook, and body upper is provided with antenna, and the fuselage back side is provided with LED.
Further, described fuselage interior is provided with music player, radio receiver module and warning horn.
Further, described power supply is 5V direct supply.
Further, the audio frequency data of reception also by the wireless communication audio decoding data of reception and decompression, can be sent to loud speaker by radio frequency module through loud speaker and play by described audio frequency coding/decoding module.
Further, the microphone U104 of smart mobile phone selected by described microphone.
Further, described intercommunication module selects A1852 module.
The interphone of the present invention has that low in energy consumption, integrated level height, strong interference immunity, radio signal transmission are stable, long transmission distance, and input and output tonequality is good, transmission efficiency height, the advantage that volume is little, it is possible to significantly improve working efficiency. Transfer passes through wireless network transmissions, it is possible to realize on a large scale, remote wireless data communication. Transmit distance and can reach 200 meters, it is preferable that 25-75 rice. By adopting intercommunication module, and audio frequency coding/decoding module and radio frequency module are electrically connected with intercommunication module, solve the intercommunication function that mobile terminal cannot realize between terminal and terminal when disconnecting networked environment.
