Description
Technical field
The present invention relates to speaker unit technical field, be specifically related to New-type loudspeaker vibrating diaphragm.
Background technology
Loud speaker is that the signal of telecommunication is changed into a kind of very conventional electro-acoustic transducer device of acoustical signal; Vibrational system, magnetic circuit system and paving auxiliary system composition is generally comprised in loud speaker; Wherein vibrational system forms by boring basin, diaphragm, locating branch slice, dust cover and voice coil loudspeaker voice coil, and magnetic circuit system is made up of magnet, upper conduction magnetic board, lower magnetic conductive board, pole body, and paving auxiliary system is made up of frame, press strip, lead-out wire and wiring end sheet etc.;
Shown in Figure 1, when installing speaker diaphragm, generally by glue, diaphragm is bonded on frame and voice coil loudspeaker voice coil, but when playing glue, glue can stick the ring of diaphragm, can affect loud speaker quality, therefore needs the junction between diaphragm and voice coil loudspeaker voice coil and the junction between diaphragm and frame, that all reserves level dodges space 13, thus ensure assembling time diaphragm and voice coil loudspeaker voice coil between junction and between diaphragm and frame the glue of junction can not stick the ring of diaphragm; But the sacrifice in this part space, can make the design of loud speaker be restricted, overall performance reduces.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of glue of avoiding and overflow on the ring of diaphragm, and the New-type loudspeaker vibrating diaphragm of ring width can be widened.
Realize technical scheme of the present invention as follows:
New-type loudspeaker vibrating diaphragm, comprises and is positioned at that middle position is plane horizontal part, to be positioned at ring portion that horizontal part periphery is downward recess and to be positioned at periphery, ring portion be plane edge part; Both sides, described ring portion are equipped with flange upwards; Described ring portion is connected with horizontal part by the flange of horizontal part side, and the keep to the side flange of side, edge of described ring portion is connected with edge part.
Have employed above-mentioned scheme, diaphragm is effectively utilized and dodges space, make the performance of diaphragm reach optimization, diaphragm can avoid glue water mitigation in assembling process simultaneously; Do not change material, on the basis of size, resonance frequency and the distortion of loud speaker can reduced, reach the object improving speaker performance.
Described flange is trough shape.Because flange is trough shape, the glue overflowed will move up along flange gentle slope upwards, in this course, due to the inclined-plane that gentle slope is upwards arc, change overflow the direction of motion of glue as the direction that is inclined upwardly into from horizontal direction, what effectively can shorten to the horizontal direction of glue design with this dodges space; Because the gentle slope that flange is downward is curved and continuous with ring, to increase the width of ring.
Described flange is isosceles trapezoid shape, and this isosceles trapezoid end face adopts arc transition.Because flange is isosceles trapezoid shape, the glue overflowed will move up along flange gentle slope upwards, in this course, because gentle slope is upwards the inclined-plane tilted, change overflow the direction of motion of glue as the direction that is inclined upwardly into from horizontal direction, what effectively can shorten to the horizontal direction of glue design with this dodges space; The gentle slope downward due to flange and ring are continuous, to increase the width of ring.
Described flange horizontal width is 0.1mm-0.5mm.When flange horizontal width is within the scope of 0.1mm-0.5mm, when can effectively ensure to play glue, glue can not spread on ring.
New-type loudspeaker, comprises frame, is contained in the magnet assembly in frame, vibrating device; Described vibrating device comprises the diaphragm on frame end face and drives the vibrating member of diaphragm vibration; Described vibrating member is suspended in above magnet assembly; Described diaphragm comprises and is positioned at that middle position is plane horizontal part, to be positioned at ring portion that horizontal part periphery is downward recess and to be positioned at periphery, ring portion be plane edge part; Both sides, described ring portion are equipped with flange upwards; Described ring portion is connected with horizontal part by the flange of horizontal part side, and the keep to the side flange of side, edge of described ring portion is connected with edge part; Described diaphragm edge portion is bonding with frame end face, and described diaphragm horizontal part is bonding with vibrating member end face; Packing washer is provided with above diaphragm on described basin bone.
Have employed above-mentioned scheme, diaphragm is effectively utilized and dodges space, make the performance of diaphragm reach optimization, diaphragm can avoid glue water mitigation in assembling process simultaneously; Do not change material, on the basis of size, resonance frequency and the distortion of loud speaker can reduced, reach the object improving speaker performance.
Described magnet assembly comprises the magnetic cover be embedded in bottom frame, is provided with magnet steel and pole piece successively above magnetic cover.By arranging magnet steel and pole piece for generation of magnetic field, vibrating member is driven to move up and down.
Described vibrating member is voice coil loudspeaker voice coil.When audio signal is by after voice coil loudspeaker voice coil, coil can produce magnetic field, and this magnetic field and magnet assembly cooperatively interact, and produces vibration, restores sound.
Described flange is trough shape.Because flange is trough shape, the glue overflowed will move up along flange gentle slope upwards, in this course, due to the inclined-plane that gentle slope is upwards arc, change overflow the direction of motion of glue as the direction that is inclined upwardly into from horizontal direction, what effectively can shorten to the horizontal direction of glue design with this dodges space; Because the gentle slope that flange is downward is curved and continuous with ring, to increase the width of ring, improve speaker performance.
Described flange is isosceles trapezoid shape, and this isosceles trapezoid end face adopts arc transition.Because flange is isosceles trapezoid shape, the glue overflowed will move up along flange gentle slope upwards, in this course, because gentle slope is upwards the inclined-plane tilted, change overflow the direction of motion of glue as the direction that is inclined upwardly into from horizontal direction, what effectively can shorten to the horizontal direction of glue design with this dodges space; The gentle slope downward due to flange and ring continuously, to increase the width of ring, improve speaker performance.
Described flange horizontal width is 0.1mm-0.5mm.When flange horizontal width is within the scope of 0.1mm-0.5mm, when can effectively ensure to play glue, glue can not spread on ring.
