Abstract
The utility model discloses a thin loudspeaker. The loudspeaker comprises a loudspeaker frame, a lower piece, a main magnet, an inner pole piece, an auxiliary magnet, an outer pole piece, a diaphragm arranged above the inner pole piece and connected to the loudspeaker frame, a voice coil bobbin arranged on the lower surface of the diaphragm, and a voice coil winding around the voice coil bobbin. An annular damper is arranged between the voice coil and the outer pole piece provided with a groove cooperating with an outer ring of the damper, and the part of the damper that is connected to the outer pole piece is disposed inside the groove. As the damper is arranged between the voice coil and the outer pole piece and the outer pole piece is provided with the groove, the inner diameter of the auxiliary magnet can be reduced to increase magnetic force to improve sensitivity. Meanwhile, the damper is added to the loudspeaker without increasing the thickness of the loudspeaker. Support by the damper enables the voice coil to maintain vertical movement and improves the low-frequency effects of the loudspeaker.
Description
Technical field
the utility model relates to loud speaker field, particularly a kind of thin speaker.
Background technology
existing thin speaker, due to thickness relationship, its inner space is at full stretch, generally bullet ripple cannot be installed therein, play ripple in loud speaker for locating voice coil loudspeaker voice coil, control low-frequency resonance frequency simultaneously, the maximum displacement of restriction voice coil loudspeaker voice coil, avoid voice coil loudspeaker voice coil to jump out magnetic gap scope, to vibrations, provide suitable damping simultaneously, improve LF-response and quality factor, to guarantee voice coil loudspeaker voice coil, the mechanical strength that vibrating diaphragm is good and lower resonance frequency and less distortion, therefore, install to play always less-than-ideal defect of tonequality that ripple caused current thin speaker.
Summary of the invention
the purpose of this utility model is to provide a kind of thin speaker that plays ripple that has.
for achieving the above object, the technical solution adopted in the utility model is: a kind of thin speaker, it comprises speaker frame, be arranged on lower of described speaker frame bottom, be arranged on the main magnetic at described lower middle part, be arranged on the interior pole piece of described main magnetic upper surface, be arranged on described lower upper and around the secondary magnetic of described main magnetic, be arranged on the outer pole piece on described secondary magnetic, be arranged on the vibrating diaphragm that described interior pole piece top connects described speaker frame, be arranged on the speech coil framework of described vibrating diaphragm lower surface, the voice coil loudspeaker voice coil coil of winding on described speech coil framework, described voice coil loudspeaker voice coil coil is arranged in the magnetic gap between described interior pole piece and described outer pole piece, between described voice coil loudspeaker voice coil coil and described outer pole piece, be provided with annular bullet ripple, described outer pole piece is provided with the groove matching with described bullet ripple outer ring, the coupling part of described bullet ripple and described outer pole piece is arranged in described groove.
preferably, described groove is positioned at the bottom of described outer pole piece.
preferably, described bullet ripple inner ring is connected to the bottom of described voice coil loudspeaker voice coil coil.
because technique scheme is used, the utility model compared with prior art has following advantages:
because the utility model is by being arranged on bullet ripple between voice coil loudspeaker voice coil coil and outer pole piece, and on pole piece, be provided with groove outside, the internal diameter of secondary magnetic can be dwindled, increase magnetic force to improve sensitivity, can under the prerequisite that does not increase loud speaker thickness, for increasing, thin speaker play ripple simultaneously, by playing the support of ripple, voice coil loudspeaker voice coil coil can be maintained and move both vertically, also promoted the low-frequency effect of thin speaker.
Accompanying drawing explanation
accompanying drawing 1 is cross-sectional schematic of the present utility model.
in above accompanying drawing: 1, speaker frame; 2, lower; 3, main magnetic; 4, interior pole piece; 5, secondary magnetic; 6, outer pole piece; 7, vibrating diaphragm; 8, speech coil framework; 9, voice coil loudspeaker voice coil coil; 10, play ripple; 11, groove.
Embodiment
below in conjunction with embodiment shown in the drawings, the utility model is further described:
embodiment mono-: shown in accompanying drawing 1, a kind of thin speaker, it comprises speaker frame 1, be arranged on lower 2 of speaker frame 1 bottom, be arranged on the main magnetic 3 at lower 2 middle parts, be arranged on the interior pole piece 4 of main magnetic 3 upper surfaces, be arranged on lower 2 and around the secondary magnetic 5 of main magnetic 3, be arranged on the outer pole piece 6 on secondary magnetic 5, be arranged on the vibrating diaphragm 7 that interior pole piece 4 tops connect speaker frame 1, be arranged on the speech coil framework 8 of vibrating diaphragm 7 lower surfaces, the voice coil loudspeaker voice coil coil 9 of winding on speech coil framework 8, voice coil loudspeaker voice coil coil 9 is arranged in the magnetic gap between interior pole piece 4 and outer pole piece 6, between voice coil loudspeaker voice coil coil 9 and outer pole piece 6, be provided with annular bullet ripple 10, play the bottom that ripple 10 inner rings are connected to voice coil loudspeaker voice coil coil 9, play the bottom that ripple 10 outer rings are connected to outer pole piece 6, outer pole piece 6 bottoms are provided with groove 11, play ripple 10 and are arranged in groove 11 with the junction of outer pole piece 6.
because the present embodiment is by being arranged on bullet ripple 10 between voice coil loudspeaker voice coil coil 9 and outer pole piece 6, and on pole piece 6, be provided with groove 11 outside, the internal diameter of secondary magnetic 5 can be dwindled, increase magnetic force to improve sensitivity, can under the prerequisite that does not increase loud speaker thickness, for increasing, thin speaker play ripple 10 simultaneously, by playing the support of ripple 10, voice coil loudspeaker voice coil coil 9 can be maintained and move both vertically, also promoted the low-frequency effect of thin speaker.
above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection range of the present utility model.
