Brief description of the drawings
Accompanying drawing 1 is a kind of structural representation of New-type loudspeaker of the utility model；
Accompanying drawing 2 is the structural representation of vibrating diaphragm in loudspeaker shown in accompanying drawing 1.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
It refer to Fig. 1 to Fig. 2, a kind of loudspeaker, including support 10, protecgulum 40, contact 20, vibrational system 30 and magnetic circuit
System, the support 10 surround accommodating chamber with the protecgulum 40, and the vibrational system 30 is located at the appearance with the magnetic circuit system
Receive intracavitary.The vibrational system 30 includes voice coil loudspeaker voice coil 32 and vibrating diaphragm 31, the contact 20 directly or indirectly with the contact
20 electrical connections, the voice coil loudspeaker voice coil 32 pass through the contact 20 and outside circuit board electrical connection.
The magnetic circuit system includes magnetic conductive board 53, magnet 52 and washer 51, and the magnetic conductive board 53 has flange 531, described
Magnet 52 is located between the magnetic conductive board 53 and the washer 51, is had between the side wall of the flange 531 and the magnet 52
Gap, the voice coil loudspeaker voice coil 32 are stretched into the gap.
The vibrating diaphragm 31 is rectangular, and the vibrating diaphragm 31 includes vibrating diaphragm body 3110, central part 3120, flange part 3130, the
One pattern portion 3123 and the second pattern portion 3140, the central part 3120 have center pad pasting 3121, the center pad pasting 3121
The short side of semicircle first that the first long side and two faces set including two faces sets and be open relative, first flower
Line portion 3123 is arranged at the center of the center pad pasting 3121, including several are using the first long side perpendicular bisector as axle pair
Claiming the camber line 3123 for setting and being open relative, the length of the camber line 3123 gradually increases on the direction away from the center line,
The central point of the camber line 3123 was all fallen within the center and the perpendicular straight line of the perpendicular bisector；Pass through described
The setting of one pattern portion 3123, the shape of first pattern portion 3123 more meet actual shape of the vibration wave in transmittance process
State, therefore in actual use, the center pad pasting 3120 can more accurately coordinate the vibration of vibration wave, enhance institute
State the pliable of center pad pasting.
In a ring, ring is located at the excircle of the center pad pasting 3121 to the flange part 3130, and the flange part 3130 wraps
Include the second long side 31 and two face settings and the second short side of semicircle 3132 for being open relative that two faces are set；Because
Second short side 3132 is relative to second long side 3131, the closer center pad pasting, so second short side
3132 width is more than the width of second long side 3131, so can not be because second long side 3131 is close described
Center pad pasting 3120, and width has influence on greatly very much the sensitivity of the center pad pasting 3120, but the vibrating diaphragm sheet can be strengthened
The rigidity of body 3110.In the present embodiment, define：The width of second short side 3132 is w1, second long side 3131
Width is w2, it meets：w1=2w2.By such setting, the flange part 3130 can strengthen the vibrating diaphragm body 3110
Rigidity, but do not influence to reduce the sensitivity of the vibrating diaphragm body 3110.
It is right between first short side and second short side 3132 in order to further enhance the rigidity of the vibrating diaphragm body
Title is provided with second pattern portion 3140, and second pattern portion 3140 has some annular pattern ripples.It can strengthen described
The rigidity of vibrating diaphragm body 3110, because second pattern portion 3140 is relatively close to the center pad pasting 3120, therefore, in order to not
The sensitivity of the center pad pasting 3120 is influenceed, the height of second pattern portion 3140 is less than the height of second short side 3132
Degree, in the present embodiment, definition：The height of second pattern portion 3140 is h1, the height h of second short side 31322, its
Meet：By such setting, second pattern portion 3140 can cooperate with the flange part 3130, increase
The rigidity of the strong vibrating diaphragm body 3110, again will not because of second pattern portion 3140 close to the center pad pasting 3120, and
The sensitivity of the center pad pasting 3120, while such high low setting are influenceed, also greatly reduces the vibrating diaphragm body 3110
Weight.
The center pad pasting 3120 is arranged at the center of the vibrating diaphragm body 3110, in actual use, institute
State center pad pasting 3120 to be vibrated according to the vibration of voice coil loudspeaker voice coil, and then send sound, and in fact, vibrating diaphragm vibration when, only in
The vibration of heart position plays the fine or not effect of the size and tonequality that determine sound, in the present embodiment, definition：The center
The area of pad pasting 3120 is s1, the area of the vibrating diaphragm body 3110 is S, and it meets：The center pad pasting 3120
Area be the vibrating diaphragm body 3110 1/3rd, both meet the requirement of voice coil vibrations enough, and can enough reduces vibrating diaphragm
Weight, while reducing weight, the requirement of tonequality is disclosure satisfy that again.
In order to be accurately positioned the relative position of the center pad pasting 3120 and the vibrating diaphragm body 3110, described in two
The medium position of first long side is provided with breach 3122, and the breach is rectangular, and the breach is corresponded on the vibrating diaphragm body
3122 position is provided with the protuberance being adapted with the breach 3122.Pass through matching somebody with somebody for the protuberance and the breach 3122
Close, determine the correct position of the center pad pasting 3120.
In order to during practical set, reduce the displacement of the vibrating diaphragm body 3110, in four of the vibrating diaphragm body
Corner is provided with fixed part 3111.
Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements done etc., the utility model protection should be included in
Within the scope of.
