Abstract
The utility model is applied to the technical field of vehicles, and provides a vehicle rearview mirror capable of acquiring audio frequency. The vehicle rearview mirror comprises a shell, a circuit board arranged in the shell, a de-noising module arranged on the circuit board, and a plurality of microphones electrically connected with the de-noising module. The vehicle rearview mirror capable of acquiring the audio frequency can effectively eliminate environmental noise in a vehicle.
Description
Technical field
The utility model belongs to vehicle technology field, relates in particular to a kind of vehicular rear mirror that gathers audio frequency.
Background technology
Along with extensively popularizing of automobile, the function that automobile has from strength to strength.Nowadays the back mirror of function singleness can have the functions such as navigation, speech talkback and driving recording in the past, the navigation of take is example, user only need be by the title of a certain destination of phonetic entry, the vehicular rear mirror with navigation feature can be identified the voice of user's input, and navigates according to the result of identification.Although above-mentioned functions provides convenience to user, but also there is defect, because vehicle is in driving process, environmental noise is around very large, when particularly user opens vehicle window, back mirror is correct environment-identification noise and people's voice signal almost, causes the functional failures such as navigation or speech talkback, causes inconvenience to the user.
Utility model content
The object of the utility model embodiment is to provide a kind of vehicular rear mirror that gathers audio frequency, is intended to solve existing back mirror and due to environmental noise, causes the problem of the functional failures such as navigation.
The utility model embodiment is achieved in that a kind of vehicular rear mirror that gathers audio frequency, comprises housing and is installed on the circuit card in described housing; Described vehicular rear mirror also comprises: be arranged at the noise elimination module on described circuit card, and a plurality of microphones that are electrically connected with described noise elimination module respectively.
Further, described a plurality of microphone is arranged at respectively ，Cheng angle of inclination, the both sides placement of described back mirror.
Further, described angle of inclination is 30 to 60 degree.
Further, also comprise with described noise elimination module and being connected, the sound after de-noising is sent to the wireless communication module of wireless network.
Further, also comprise with described noise elimination module and being connected, control the switch module of described noise elimination module switch.
In the utility model embodiment, the vehicular rear mirror that can gather audio frequency gathers sound by a plurality of microphones, one of them microphone is used for providing clear call, all the other microphones are used for abating the noise, make vehicular rear mirror can correctly identify user's voice signal, to user, provide good experience.
Accompanying drawing explanation
Fig. 1 is a constructional drawing of the vehicular rear mirror of the gathered audio frequency that provides of the utility model embodiment;
Fig. 2 is another constructional drawing of the vehicular rear mirror of the gathered audio frequency that provides of the utility model embodiment.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The utility model embodiment proposes a kind of vehicular rear mirror that gathers audio frequency.As shown in Figure 1, the vehicular rear mirror of the embodiment of the present invention comprises housing, is installed on circuit card 2 in housing, is arranged at noise elimination module 3 on circuit card 2 and and a plurality of microphones of being electrically connected of noise elimination module 3 (the utility model be take 2 microphones: microphone 41 and microphone 42 describe as example).
In the utility model embodiment, microphone 41 and microphone 42 can be arranged on housing, also can be arranged at (built-in microphone) on circuit card 2.In order to reach better effect, microphone 41 and microphone 42 should be placed in respectively the diverse location of vehicular rear mirror, comparatively ideal embodiment is microphone 41 and microphone 42 to be placed in respectively to the ，Ru left and right sides, two ends or the upper and lower both sides of back-mirror housing or circuit card 2.Microphone 41, near user, provides user's clear voice, and microphone 42 is positioned at the position away from from user, and user abates the noise.Place at the ，Cheng angle of inclination, both sides that in the present embodiment, above-mentioned microphone 41 and microphone 42 are arranged at respectively back mirror, and this angle of inclination can arrange by concrete needs, such as can be between 30 to 60 degree.
Because microphone 41 and microphone 42 are when the user's communication, different apart from the distance of source of sound, so the volume that two microphones pick up is also different, utilize this difference, can filtered noise retain people's voice signal.Be specially when call, the environmental noise that two microphones pick up is essentially identical, and the people's of record voice signal has volume poor (according to the difference of two microphone correlation distances and different, as 8db), microphone 42 gathers after environmental noise, inputs to noise elimination module 3.Noise elimination module 3 generates compensating signal by decoding, then the sound signal gathering in conjunction with microphone 41, i.e. more than 90% environmental noise of stackable counteracting.
Further, noise elimination module 3 also can be pre-stored in the environmental noise under the silent situation of user, so when user speaks, and can be more rapidly and the environmental noise of decaying accurately.
The noise elimination module 3 of the utility model embodiment can be built in the CPU of vehicular rear mirror, and the CPU by vehicular rear mirror realizes, and without arranging separately, can save hardware cost.
As shown in Figure 2, the vehicular rear mirror of the gathered audio frequency of the utility model embodiment also can comprise a wireless communication module 5 being connected with noise elimination module 3, and the voice signal after noise elimination module 3 is processed is sent to wireless network.Now, vehicular rear mirror can, by the voice signal abating the noise for multiple application such as navigation, speech talkbacks, make above-mentioned application more accurate.
In addition, the utility model embodiment also can arrange a switch module 6, is connected with noise elimination module 3, controls the switch of noise elimination module 3.Because noise elimination module 3 need to take some system resources when abating the noise, when vehicle is in very quiet environment, when carrying out de-noising, user can close noise elimination module 3 by switch module 6, to save system resource.
The utility model embodiment be take two microphones as example describes, and in practical application, the quantity of microphone can be set as required, and a part of microphone is used for providing voice, and another part is used for abating the noise.The vehicular rear mirror of the utility model embodiment, in driving recording or navigation procedure, can eliminate environmental noise effectively, and the functions such as navigation are realized more accurately, has greatly improved user experience.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
