A kind of wearable device with noise elimination apparatusTechnical field
The present invention relates to one and there is noise elimination apparatus equipment, particularly a kind of microphone noise cancellation element of intelligent watch.
Background technology
Along with the development of electronic technology, occurred increasing smart machine in the life of people, the life for us brings quick and convenient.In recent years, the fusion of necessity in electronic equipment and people being lived, such as: wearable device, portable set, implanted equipment etc., all become the emphasis of each large enterprises research and development, people are also grown to even greater heights for the enthusiasm of Intelligent worn device.In Intelligent worn device, intelligent watch is expected to especially after smart mobile phone, becomes individual intelligent terminal the most popular of future generation.
Because wearable device is user's use next to the skin, generally there is the feature that volume is little and easily portable, such as intelligent watch, smart mobile phone etc.Because intelligent watch is than smart mobile phone, volume obviously has more miniaturized feature, cause the degree exquisite in workmanship of intelligent watch and integration all far above smart mobile phone, will certainly will will have influence on the internal circuit design of intelligent watch so thus.In order to enrich the function of intelligent watch, intelligent watch arranges microphone function, thus the function such as call, recording by intelligent watch can be realized.But the small size due to intelligent watch causes microphone place in circuit to adopt single-ended connection, but occur in reality that microphones voice signal exists background noise, the technical problem that speech quality is lower.
Summary of the invention
In order to solve the problem of above-mentioned existing intelligent watch, the present invention proposes the wearable device with noise elimination apparatus, there is wearable components and main body, in this main body, be provided with processing module and noise elimination apparatus, in this processing module, be provided with embedded system.In this main body, also there is WIFI module, GPS module, step counting system.This noise elimination apparatus comprises collection terminal, for image data signal; Difference channel portion, for carrying out except process of making an uproar to described data-signal; Audio processing chip, for obtaining the data-signal after the process of described difference channel portion.By technical scheme of the present invention, external voice acquisition quality is improved.
This noise elimination apparatus is for gathering audio instructions, and by described embedded system, WIFI module, multiple terminal equipment in connecting Internet, obtains and handles network resources; By the audio instructions that this noise elimination apparatus gathers, can control GPS module and step counting system and select.Achieve highly effective gathering user command, to the mode that intelligent watch controls, for the use of user is provided convenience.This intelligent watch also has independently USB memory module, for the data-signal that data on file information and this noise elimination apparatus obtain; Except the voice command gathered by noise elimination apparatus is controlled except intelligent watch, described main body also has touch-screen, and user selects input of control commands by this touch-screen, realizes multiple control modes, facilitates user.

The circuit diagram of the noise elimination apparatus of Fig. 1 wearable device.
Embodiment
This intelligent watch has watchband and main body, in main body, be provided with processing module, is provided with embedded system in processing module.This MIC mouth is arranged in the main body of intelligent watch, can realize the collection to audio frequency.
As shown in Figure 1, the noise elimination apparatus of this wearable device, by on positive input terminal 3 that the positive terminal 1 of the MIC mouth be arranged in intelligent watch main body and the negative pole end 2 of MIC1 are connected to difference channel respectively and negative input end 4, by difference channel to by being divided two-way by MIC input signal, the MCP1 end of accessing to audio process chip and MCN1 end realize respectively.When the effect of difference channel is to make the negative pole end 2 obtaining information data of the positive terminal 1 of MIC1 and MIC1, the background noise simultaneously obtained, cancel out each other in difference channel, thus obtain MCP1 end and the MCN1 end that clear, muting voiceband data signal inputs to audio processing chip.The voice collecting quality of this intelligent watch is improved thus.
This embedded system can compatible multiple existing operating system, thus realize the connection of this smart mobile phone and multiple existing equipment, as DVD, mobile phone, computer, notebook, reading machine etc.This embedded system can be Linux or android system.This intelligent watch can directly run multiple mobile phone software by embedded system, as micro-letter, QQ, 360 mobile phone assistants etc.
Bluetooth module, WIFI module is also provided with, for the interconnected communication of multiple terminal in intelligent watch and the Internet in the processing module of this intelligent watch.
This intelligent watch also has independently USB memory module, for the data information that stores intelligent watch inside and the data and information obtained from the Internet.
The body surfaces of this smart mobile phone also has touch-screen, and such as this touch-screen can be capacitance touch screen, and user can select input of control commands by touch-screen, thus controls the several functions of intelligent watch.
Also there is GPS module in the processing module of this intelligent watch, by receiving gps signal, obtaining real-time positioning information intelligent watch being worn to user.
This intelligent watch also has step counting system, can obtain and record the action of user.
The noise elimination apparatus of this intelligent watch can make the phonetic order of user clearly be gathered and identify, thus realizes and being combined of several functions, and is controlled the work of this functional module, greatly facilitate the experience of client by voice command.
