Background technology
Coil-moving speaker is common speaker types, is usually provided with vibrating diaphragm, and vibrating diaphragm bottom is fixed with voice coil loudspeaker voice coil, voice coil loudspeaker voice coil
Thus driving vibrating diaphragm sounding, vibrating diaphragm includes central part and edge part, central part and edge part junction to up-down vibration in magnetic gap
For annular recess, below this depressed part, connect voice coil loudspeaker voice coil, this depressed part may also be referred to as voice coil loudspeaker voice coil position.
For example in Chinese invention patent " moving-coil type electro-acoustic conversing device " (CN101227766A), disclose a kind of moving-coil type
Loudspeaker, set vibrating diaphragm is exactly aforementioned structure.In Chinese invention patent " multifunction speaker " (CN103209377A)
Disclose a kind of coil-moving speaker, set vibrating diaphragm is also aforementioned structure.
The vibrating diaphragm of this spline structure is when sending high-frequency signal, because the insufficient strength of voice coil loudspeaker voice coil position, is easily occurring dividing herein
Cut vibration (direction of vibration of diaphragm diverse location is contrary, and energy is cancelled out each other).Finally on frequency response curve, paddy is fallen in performance, and
High frequency tonequality resolution is poor.
Loudspeaker back cavity is divided into two parts of V1 and V2 by voice coil loudspeaker voice coil, and as shown in Figure 2, Figure 4 shows, magnetic circuit is non-with the gap of voice coil loudspeaker voice coil
Often little (conventional is 0.15mm-0.4mm), this rear cavity configuration, the narrow slit of magnetic circuit, resonance can be produced with back cavity, similar to band resistance
Filter construction, the ability of loss fixed frequency band, it is unsmooth therefore to easily cause frequency response curve, peak valley.
Content of the invention
In view of the above problems, the invention provides a kind of diaphragm of loudspeaker, by arranging reinforcement in voice coil loudspeaker voice coil position, strengthen
Intensity at voice coil loudspeaker voice coil position is it is suppressed that diaphagras herein.Significantly increase the direct gas permeability of rear chamber V1 and V2 simultaneously, connect
It is bordering on a complete back cavity it is suppressed that bandreject filtering acoustically is so that curve is more straight.
The present invention additionally provides a kind of loudspeaker simultaneously, employs the above-mentioned diaphragm of loudspeaker.
For reaching above-mentioned purpose, the technical scheme is that and be achieved in that：
A kind of diaphragm of loudspeaker, including central part and edge part, described central part and edge part junction are ring-shaped depression
Portion, connects voice coil loudspeaker voice coil below this depressed part, described annular recess is evenly equipped with several reinforcements, and described reinforcement raises up,
Reinforcement is internally formed channel connection central part and edge part overlay area, described reinforcement, central part and edge part one system
Become.
Further, the described diaphragm of loudspeaker is circular or Long Circle, and the cross section in the middle part of described reinforcement is arc.
Further, described reinforcement is located at the partly isometric of central part and edge part, or be located at edge part length big
In the length positioned at central part.
Further, described reinforcement top is the arc raising up, or the arc for concave downward.
A kind of loudspeaker, is provided with the above-mentioned diaphragm of loudspeaker, disconnection between the depressed part of the described diaphragm of loudspeaker and voice coil loudspeaker voice coil
Connect.
Further, the central part of described vibrating diaphragm and edge part cover two chambers inside and outside formation, described reinforcement connection two
Individual chamber.
Further, described loudspeaker includes ring support, and the edge part of described vibrating diaphragm is fixing on the bracket, is fixing
Place is provided with trim ring.
Further, it is provided with magnetic cover in the middle part of described ring support, be provided with magnet in described magnetic cover, be provided with above magnet
Washer plate, described magnetic cover, magnet and washer plate are located at below described vibrating diaphragm.
Further, described washer plate, magnet and magnetic cover are provided with centre bore, three centre bore up/down perforations.
Further, the gap between described washer plate, the lateral wall of magnet, and the madial wall of described magnetic cover is magnetic gap, institute
State voice coil loudspeaker voice coil up and down reciprocatingly to vibrate in magnetic gap.
In sum, the present invention has advantages below：
The present invention increased the raised ribs position of array at the voice coil loudspeaker voice coil position of vibrating diaphragm, and segmentation during suppression dither is shaken
Dynamic, improving high frequency resolution has very big benefit, simultaneously the gas permeability between lifting back cavity (V1 and V2), humorous between suppression cavity
Shake, the smoothness of lifting frequency response curve.
And this kind of diaphragm structure will not increase the cost of loudspeaker parts manufacture.
The present invention significantly increases the direct gas permeability of rear chamber V1 and V2, close to a complete back cavity it is suppressed that
Bandreject filtering acoustically is so that frequency response curve is more straight.
