Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments, based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
As shown in Figure 1, the sound pick up equipment includes: non-the embodiment of the invention provides a kind of sound pick up equipment of intelligent air condition
Flat panel 101, pickup channel 102, at least two microphones 103 and microphone pressing plate 104；Wherein,
Pickup hole 1011 is provided on the non-planar panel 101；
The pickup channel 102 is corresponded with the pickup hole 1011, the pickup channel 102 and the microphone
103 correspond, and the one end in each pickup channel 102 is connected to the corresponding pickup hole 1011, and the other end is oriented to institute
The corresponding microphone 103；
At least two microphone 103 is fixedly installed on the microphone pressing plate 104.
Shell of intelligent air condition itself is with circular arc, but the structure in the pickup area of its microphone is not straight in vertical direction
Line has certain radian, forms hyperboloid, and such hyperboloid structure is the non-planar panel 101 in the embodiment of the present invention
A kind of form.In addition, non-planar panel may be single faceplate panels.
In the above-described embodiments, by the way that pickup hole is arranged on non-planar panel, and be connected with pickup hole by one end,
The other end is oriented to the pickup channel of microphone, so that microphone can pass through corresponding pickup hole and pickup channel, acquisition sound
Sound signal.Microphone is securable on microphone pressing plate as a result, and is connect by pickup channel with non-planar panel, with acquisition
Voice signal outside non-planar panel, consequently facilitating in the air-conditioning of non-planar panel microphone array installation.Also, it is each
A microphone has the pickup channel of independent collected sound signal so that between each microphone will not interaction crosstalk, to mention
The accuracy rate of high sound signal acquisition.
Wherein, in order to realize speech recognition, voice-based orientation recognition and Application on Voiceprint Recognition, microphone array can be by 2
A, 4 microphone compositions, i.e. at least two microphones are preferably 2 or 4 microphones.
In addition, the sound pick up equipment can be wrapped further in order to which each microphone to be firmly mounted on microphone pressing plate
Microphone installing component is included, which is mounted on microphone pressing plate, for placing multiple microphones.Microphone
Pressing plate can then fix microphone, the second acoustic material, and microphone is avoided to fall off with the second acoustic material.
In an embodiment of the invention, the pickup hole 1011 is single hole or porous, and the pickup hole 1011 is located at institute
The central area in the pickup area of the corresponding microphone 103.
It is understood that microphone is only capable of accurate collected sound signal in a certain range, the range is as each
The corresponding effective pickup area of a microphone, therefore, in order to guarantee that Mike's wind energy inside intelligent air condition accurately acquires sound letter
Number, pickup hole 1011 need to be corresponding with the central area in pickup area of microphone 103, so that microphone can pass through pickup hole standard
True collected sound signal, and the aesthetic feeling of the appearance of non-planar panel 101 is combined, pickup hole 1011 can be single hole, or
It is porous.For example, effective pickup area of microphone is the border circular areas of diameter 3mm, then it is super cannot to deviate microphone center for pickup hole
Cross 1.8mm.When pickup hole is single hole, the aperture in the pickup hole of circular hole is not less than 3mm, as shown in Figure 2；Rectangular pickup hole
Length is up to 3mm, width 2.5mm, as shown in Figure 3.
When the pickup hole 1011 is porous, as shown in figure 4, porous is in honeycomb, and positioned at edge in honeycomb
The distance between pickup hole 1011 and the corresponding center in pickup area of the microphone 103 are not more than default first distance threshold
Value.For example, the effective pickup area of microphone is still 3mm, then most marginal pickup hole cannot deviate in cellular pickup hole 1011
Microphone center is more than 1.8mm.
It is described to pick up in one embodiment of the invention in order to improve the validity and accuracy rate of microphone collected sound signal
The diameter in sound channel 102 is not more than 15mm, and the length in the pickup channel 102 is not more than 15mm.
In an embodiment of the invention, which may further include: the first acoustic material；Wherein, described
First acoustic material is mounted between the non-planar panel 101 and the pickup channel 102.Wherein, the first acoustic material can
Think the material composition that sound-proof material or clay etc. have soundproof effect and be easily deformed, the first acoustic material is mounted on non-planar
Between panel and pickup channel, to guarantee that panel with pickup channel is not to contact firmly, while being easily installed, have also achieved every
The purpose of sound.
Based on similar principle and purpose, sound pick up equipment provided in an embodiment of the present invention be can further include: second
Acoustic material；Wherein, second acoustic material is mounted at least two microphone 103 and the microphone pressing plate 104
Between.Wherein, second acoustic material may be the material that sound-proof material or clay etc. have soundproof effect and be easily deformed
Composition, the second acoustic material is mounted between microphone and microphone pressing plate, to avoid invalid sound from microphone rear portion
Microphone is sealed in, to improve the accuracy rate of microphone collected sound signal.
In order to further be easily installed, as shown in figure 5, in one embodiment of the invention, the front end in the pickup channel 102
Curvature it is identical as the curvature of the non-curved panel.
According to the appearance and performance requirement of intelligent air condition, various arrangement form is can be used in each microphone.Of the invention
In a kind of embodiment, at least two microphone 103 is arranged in horizontal linear, and microphone 103 described in each adjacent two
The distance between for default second distance threshold value.For example, each microphone of composition microphone array is kept in the up-down direction
Horizontal straight line, each microphone keeps a steady state value in the horizontal direction, for example, each microphone is in the horizontal direction
35mm is kept, with while guaranteeing microphone effective collected sound signal, convenient for the installation of microphone.
In another embodiment of the present invention, the first microphone 103 at least two microphone 103 with it is described
The distance between non-planar panel 101 be less than at least two microphone 103 in second microphone 103 with it is described non-planar
The distance between panel 101, and the distance between first microphone 103 and the second microphone 103 are not more than third
Distance threshold.For example, when microphone array is made of 4 microphones, intermediate two microphones and two Mikes of the right and left
The different longitudinal separation of elegance, but its longitudinal separation is no more than 7mm.
As shown in fig. 6, in embodiments of the present invention, which may further include: Soundspeaker treatment plate, fixed bottom
Seat and loudspeaker；Wherein,
The Soundspeaker treatment plate is installed on the firm banking；
