Description
Technical field
The utility model belongs to mobile unit technical field, and in particular to a kind of voice de-noising blue-tooth intelligence vehicle fills cup.
Background technology
With the fast development of mobile Internet and smart mobile phone, the function of smart mobile phone is become stronger day by day, and people is had become
Essential electronic product.Exactly because the such power of mobile phone and viscosity, people also opponent during driving
Machine produces strong dependence, and most people can be navigated using mobile phone in driving process, phone, music, or even be seen
Wechat, news etc..However vehicle environment is more special, driver when driving, if using conventional touch mobile phone screen
Interactive mode control mobile phone if, will greatly increase driving in security risk.Shown according to AUTHORITATIVE DATA, in recent years due to
It drives to have become the first killer of road using safety accident caused by mobile phone.Therefore, under vehicle-mounted scene, it is necessary to which searching is more pacified
Entirely, the easily interactive mode of people and mobile phone.
In recent years, artificial intelligence develop rapidly, intelligent sound as one of important directions, at present more at
It is ripe.Google, apple, HKUST News, Baidu etc. are absorbed in the bellwether of intelligent sound both at home and abroad, have been achieved for many progress,
Phonetic recognization rate is up to 95% or more, and starts to apply in multiple fields such as education, traffic, medical treatment.
As it can be seen that under vehicle-mounted scene, intelligent sound will slowly replace traditional interaction as completely new man-machine interaction mode
Custom makes the following driving safer, more intelligent, more convenient.However vehicle environment is relatively for voice
Complex environment, since the various noises that engine, air-conditioning, the sound of the wind that opens a window etc. are brought greatly choose speech recognition band
How war, effectively eliminate all kinds of noises, extracting the real voice command of user just seems most important.
Currently, most of user is when driving, there are navigation, phone using the main demand of mobile phone, plays music, bat
According to video recording etc..In order under vehicle-mounted scene it is more convenient, more safely use mobile phone, the relatively solution of mainstream has vehicle at present
It fills, vehicle fills cup, bluetooth headset, Baffle Box of Bluetooth, car handsfree, interactive voice class APP and the APP being used cooperatively.Wherein vehicle fills
Cup is filled with vehicle primarily to solving the problems, such as that mobile phone charges；Car handsfree, Baffle Box of Bluetooth and bluetooth headset mainly solve electricity
The problem of words, music；Mainly by intelligent sound and steering wheel Bluetooth remote control, control navigation may be implemented, dial electricity
Words play music, the function of video recording etc. of taking pictures, and function is relatively powerful.
Although existing program has been resolved the problem of just having needed function using handpiece portion in the car, there are still some not
Foot place affects the usage experience of user.It include mainly problems with：
(1) no one of existing various schemes are complete, perfect solutions, only solve single or partial function
Demand.If user expects preferable usage experience, need multiple collocation that could realize, and interior space is relatively limited, it is more
A product can seem very in disorder, or even the position conflict placed；
(2) call problem can be well solved after bluetooth headset is connect with mobile phone, but bluetooth headset loudspeaker tonequality
It is poor, be not suitable for listening to music, while bluetooth headset is worn will produce ear's discomfort, some users and uncomfortable wearing for a long time
Bluetooth headset.
(3) car handsfree is also sound quality one the problem of being connect with mobile phone by Bluetooth protocol, can well solve call
As, if relatively high to musical qualities requirement, it is also not suitable for playing music.Meanwhile this kind of product belongs to sound and puts outside, nothing
Method ensures the privacy of phone.
(4) Bluetooth audio device and FM, which emit to the mode of vehicle audio, may be implemented high-quality call and music, but
It can not equally ensure the privacy of phone.
(5) interactive voice class app can be realized simultaneously navigation, phone, music and take pictures functions, the functions such as video recording and compare
Comprehensively, but environment inside car is complicated, and noise is larger, leads to the big heavy discount of the discrimination of voice, seriously affects user experience.While by
The problem of being limited to different mobile phone permissions, there are larger differences, quite a few mobile phone all can not in terms of solving to take phone
It realizes.
For existing vehicle carried mobile phone auxiliary accessories scheme there are the problem of, the utility model merge microphone array, bimodulus
The technologies such as bluetooth, audio frequency process, FM transmittings, quick charge and wireless control, coordinate corresponding mobile phone application software, have made
Kind intelligent vehicle-carried mobile phone auxiliary plan, emphasis will solve problems with：
(1) the scattered words problem of existing product function：As complete, perfect vehicle carried mobile phone solution, from being charged to work(
It can use, construct integrated comprehensive product scheme；
(2) vehicle environment mobile phone speech identifies noise problem：Interior engine is eliminated by microphone array, air-conditioning, is opened
All kinds of noises caused by window sound of the wind etc. export clean user voice command, solve the maximum obstacle of interior intelligent sound, it is ensured that
Phonetic recognization rate；
(3) call privacy and sound quality problem：Integrated bluetooth headset, included loud speaker and FM transmitting modules, earphone carry
Three kinds of audio output mode free switchings of loud speaker and vehicle audio can ensure that privacy call, convenience and music are high simultaneously
Quality plays；
(4) fully functional consistency problem has just been needed：It realizes Voice Navigation, voice dial phone, connect and hang up, play sound
The vehicle-mounted scenes such as pleasure, ordering song by voice just need function to mobile phone.
