Abstract
The utility model provides an audio system, include: audio frequency generating device produces audio signal, audio frequency conveyer, with audio frequency generating device connects, will audio signal is coupled to in the human body, audio frequency receiving arrangement acquires and plays from the human body audio signal. Audio system need not the radio signal with the help of the external world, can transmit audio frequency or music the earphone speaker of single human body or a plurality of human bodies to through human body communication on, the not restriction of the volume of receiving transmitting data, transmission power and cost.
Description
Technical field
The utility model relates to voice communication technology, particularly relates to a kind of audio system.
Background technology
Along with improving constantly of people's living standard, the requirement of people to private room is more and more higher, and wireless headset will become the trend of future audio field development.For wired earphone, the maximum feature of wireless headset is exactly " wireless ", and be connected with source of sound by wireless carrier mode, it is more convenient to use, and user need not stick to the constraint of wire rod, can be freely movable in certain scope; Even, some wireless headsets are also built-in microphone, even if also can carry out voice-enabled chat when doing housework, the convenient degree of its scope of application and use absolutely not wired earphone can be compared.
Wireless audio communication in the market mainly contains following 3 classes: (1), Bluetooth wireless transmission; (2), infrared and radio transmission; (3), 2.4G wireless transmission.This 3 class wireless transmission has respective deficiency: the fatal shortcoming of (1), Bluetooth technology is exactly that its transmitted data amount is little, only can reach about 1M per second; (2), wireless infrared transmitting technology requires very high to directive property; Secondly, wireless infrared transmitting requires higher for emissive power, if the Infrared wireless earphone practical significance driven with battery is little; (3), the shortcoming of 2.4G technology is exactly that cost is higher, and is difficult at short notice popularize.
Human body communication is an emerging communication technology of rising in recent years, mainly in order to solve the communication issue of the interconnected LAN (Local Area Network) of human body.Human body communication utilizes human body as the transmission medium of electric signal, realizes body surface, body information interaction that is interior and medical health equipment around.
Utility model content
The utility model object is to provide a kind of audio system, is intended to solve the problem existing for prior art.
The utility model provides a kind of audio system, comprising:
Audio frequency generating means, produces sound signal;
Audio frequency conveyer, is connected with described audio frequency generating means, is coupled in human body by described sound signal;
Apparatus for receiving audio, obtains and plays described sound signal from human body.
Further, described audio frequency generating means is mobile terminal device.
Further, described audio frequency conveyer is Dongle or bluetooth earphone.
Further, apparatus for receiving audio comprises:

Above-mentioned audio system, can by audio frequency or music transmission on the earphone horn of single human body or multiple human body by human body communication without the need to the wireless signal by the external world, not by the restriction of transmitted data amount, through-put power and cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model preferred embodiment sound intermediate frequency system.
Embodiment
In order to make the technical problems to be solved in the utility model, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, a kind of audio system in the utility model preferred embodiment, comprise audio frequency generating means 10, audio frequency conveyer 20 and apparatus for receiving audio 30.
Audio frequency generating means 10 is for generation of sound signal; Audio frequency conveyer 20 is connected with described audio frequency generating means 10, is coupled in human body by described sound signal; Apparatus for receiving audio 30 obtains and plays described sound signal from human body.
Wherein, sound signal can be coupled in single human body A, also can be coupled in multiple human body A, B.That is, sound signal can be transmitted in single human body, as being transferred to apparatus for receiving audio 30A by human body A, or is transferred to apparatus for receiving audio 30B by human body B.In addition, also can transmitting in multiple human body contacted with each other, being transferred to again on apparatus for receiving audio 30B as being transferred to human body B by human body A.
In the present embodiment, described audio frequency generating means 10 is mobile terminal device.As mobile phone, panel computer, MP3/MP4 player etc.; Described audio frequency conveyer 20 is Dongle (Dongle) or bluetooth earphone.
Further, apparatus for receiving audio 30 comprises: microcontroller 31, digital power amplifier device 32 and loudspeaker 33.
Microcontroller 31 is for obtaining described sound signal and converting digital signal to after decoding, and microcontroller 31 can be that existing audio frequency obtains chip and dsp chip; Digital power amplifier device 32 is connected with described microcontroller 31, and for decoded digital signal is carried out power amplification process, digital power amplifier device 32 can adopt existing digital power amplifier chip; Loudspeaker 33 is connected, for playing audio signal with described digital power amplifier device 32.
In actual applications, can using mobile phone as audio frequency generating means 10, mobile phone exports music or sound signal, audio frequency conveyer 20 (Dongle) carries out the collection of audio frequency, coding, decoding, then be coupled to human body, by the transmission of single or multiple human body, the microcontroller 31 of apparatus for receiving audio 30 receives sound signal, sound signal is collected, analyze, decoding, and re-encoding becomes digital audio and video signals, digital audio and video signals is transferred to digital power amplifier device 32, the loudspeaker 33 finally arriving earphone exports, namely user just can hear the music or audio frequency that transmit.By human body transmission, without the need to namely obtaining by other wireless transmission, hear sound signal or music.
Above-mentioned audio system, can by audio frequency or music transmission on the earphone horn of single human body or multiple human body by human body communication without the need to the wireless signal by the external world, not by the restriction of transmitted data amount, through-put power and cost.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
