Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.Specific embodiment described herein is only for explaining the present invention, but not limitation of the invention.It also should be noted that, for convenience of description, illustrate only part related to the present invention in accompanying drawing but not full content.
Fig. 1 shows the stereogram of the miaow head frame that one embodiment of the invention provides, and miaow head frame comprises a body 10, and this body 10 is irregular cylinder, and body 10 is provided with the first miaow head bore 11 and the second miaow head bore 12.Miaow head bore is for placing pickup miaow head, the shape of miaow head bore becomes cylindrical hole according to the shape fabricating of miaow head, miaow head of the present invention refers to energy conversion device voice signal being converted to the signal of telecommunication, and miaow head, also referred to as microphone, is the Primary Component in electroacoustics system.In order to make recording device portable and smart, the miaow head that the present invention uses size less, such as diameter is the electret capacitor type miaow head of 6mm-10mm.
The first miaow head bore 11 and the second miaow head bore 12 near cylindrical on body 10, have central axis 13 and central axis 14 respectively, the angle of central axis 13 and axis 14 is 90 degree, thus makes the pickup load plane of two miaow heads angle each other be 90 degree.According to other embodiments of the invention, in XY pickup standard, the range of choices of the pickup load plane angle each other of two pickup parts is 80-130 degree, but be preferably 90 degree, this is because when angle is 90 degree, if a sound source moves along circular arc, the energy sum of two pickup parts pickups is completely equal, when to the sound source playback audition picked up, can obtain the acoustic image with stable level.The size of the miaow head bore in the present embodiment and the size approximately equal of miaow head, this closely links together with miaow head frame after making miaow head embed miaow head bore, can't come off by the impact of external force, binding agent also can be utilized in addition to be fixed miaow head further.
Miaow head frame provided by the invention usually and other devices with the use of, be such as placed in microphone, as the pickup parts of microphone.Profile due to general microphone is cylindrical, so the shape of miaow head frame can be processed according to the shape of microphone, namely a cylinder material is selected, this cylinder processes two mutual angles becomes the cylindrical hole of 90 degree or groove as the first and second miaow head bore, the shape of miaow head bore also can be processed according to the shape of miaow head, is not limited to above-mentioned cylindrical shape.Miaow head frame do not exist except miaow head bore other blank structure, just an entirety is formed after miaow head support and miaow head are combined closely, pickup parts in microphone are more stably fixed, and the shape of miaow head frame make pickup parts mounted thereto meet XY pickup standard.
Fig. 2 is the front view of the miaow head frame shown in Fig. 1, and Fig. 3 is the end view of the miaow head frame shown in Fig. 1, and the size of wherein key position, only adopts front view and end view to be described at this for convenience of description.As shown in Figure 2,3, the diameter 21 of this miaow head frame is 16.5mm, miaow head bore diameter 22 is 6mm, and the equal diameters of two miaow head bore.The size of miaow head bore is according to the size design of used miaow head, and the size of miaow head frame then designs according to the combined shaped of two miaow head bore and size.
Further, in a preferred embodiment, the material of miaow head frame is silica gel material.Silica gel material has good elasticity, certain damping, the effect of compensator or trimmer pressure can be played, thus pickup parts can be made normally to work in vigorous exercise, in addition other can also be used to have elasticity and be enough to play the making material of material as miaow head frame of fixation, such as rubber etc.
Fig. 4 shows the structure of the recording device that one embodiment of the invention provides, as shown in Figure 4, recording device comprises: shell 41, is provided with miaow head frame 42, first wire netting 43, first spongy layer 44, second spongy layer 45, second wire netting 46 in above-described embodiment in shell 41.
Wherein, be provided with the first miaow head in the first miaow head bore of described miaow head frame 42, the first miaow head of the first miaow head bore and embedding closely cooperates; Be provided with the second miaow head in second miaow head bore of described miaow head frame 42, the second miaow head of the second miaow head bore and embedding closely cooperates.
Described miaow head frame 42 is arranged between described first spongy layer 44 and described second spongy layer 45, and closely cooperate with the inwall of described first spongy layer 44, second spongy layer 45 and described shell 41, the profile of miaow head frame 42 is consistent with the inner surface contour of shell 41, and size approximately equal, and adopt binding agent to be connected with outer casing inner wall by miaow head frame, meanwhile, the position of the first and second spongy layers is relatively fixing, by sandwiched therebetween for miaow head frame 42.
Described first wire netting 43 is arranged between described first spongy layer 44 and the inwall of described shell 41.In the present embodiment; first wire netting 43 and the first spongy layer 44 horizontally set as shown in Figure 4; because common crust of the device all adopts hollow out to design to receive extraneous sound; the such as roof of Fig. 4 shown device shell is provided with hole makes sound can import device inside into, and the first wire netting 43 and the first spongy layer 44 are then as two protective layers between device outside and miaow head frame.
Described second wire netting 46 is arranged between described second spongy layer 45 and the inwall of described shell 41.In the present embodiment, the second wire netting 46 and the second spongy layer 45 vertical wraparound are on the inwall of shell 41 as shown in Figure 4, and this set then can make device inside directly contact with the external world by the through hole on anti-locking apparatus sidewall.
First wire netting 43, first spongy layer 44, second spongy layer 45, second wire netting 46 plays effect that is dust-proof, windproof, damping, can further improve the dexterity of recording device.In addition, according to other embodiments of the invention, the size of other the necessary electric elements in this recording device is also paid attention to, the size of such as PCB circuit, the size etc. of signal converting circuit.Miniaturized device can ensure that recording device has less volume, and make sound pick-up outfit possess higher dexterity, and make recording device go for more special occasion, such as, in extreme sport, sportsman can carry with.Compared with the recording device of existing outfit monophony pickup parts, miaow head frame provided by the invention is the parts that recording device provides that realizes an XY pickup standard.
