Abstract
The utility model discloses a soft coating woofer speaker, which comprises a magnetic circuit system with an annular magnet and an annular magnetizer, a vibrating system with a columnar voice coil skeleton, a voice coil, a locating spring plate and vibrating diaphragms as well as an inverted cone shape basin, and is characterized in that: each vibrating diaphragm is a round plane soft plastic film with excellent elasticity, and the vibrating diaphragms are fixed on an annular vibrating diaphragm rim. The vibrating diaphragms are divided into vibrating diaphragms with single resonant point and vibrating diaphragms with multiple resonant points; and the vibrating diaphragms with multiple resonant points can be formed by affixing different frequency dividing rings on concentric circles of the vibrating diaphragms or changing the thicknesses of the vibrating diaphragms at different regions of concentric circles, so the undertone, particularly super bass effects of the soft coating speaker can be produced completely without sound box.
Description
Technical field
The utility model relates to a kind of loud speaker, especially a kind of panel speaker.
Background technology
Loud speaker also has panel speaker, ribbon speaker, magnetic speaker, electrostatic loudspeaker, piezoelectric speaker etc. except common electrodynamic loudspeaker.From the commercial market, electrodynamic loudspeaker still is a main flow.In recent years, because the television set that matches with ultrathin display is popular, panel speaker is also because of wide, the comprehensive directive property of its Hz-KHz, particularly its ultra-thin characteristic, the market share of this commodity is increased thereupon, but it still can't contend with electrodynamic loudspeaker.Tracing it to its cause mainly is that panel speaker is poor at the expressive ability of bass effect, can't go back the sound that primary frequency is lower than 200Hz, and music lacks shock sense and appeal.And electrodynamic loudspeaker is little owing to Hz-KHz, and bass unit must use simultaneously with voice unit even middle pitch unit usually, has therefore increased the cost of stereo set greatly.Especially bass unit, because its cup effect and the anti-phase each other characteristic of front and back sound of vibrating diaphragm, during actual the use, the volume of it must being packed into is doted on relatively just can avoid its " cavitation " and " acoustic short circuit " phenomenon in the big casing, brought inconvenience for manufacturing, transportation and the use of stereo set.Therefore, research and develop and design the urgent need that a kind of thin thickness, new-type loud speaker that bass effect is good have become market.
Summary of the invention
The purpose of this utility model is to provide its bass effect of a kind of thin thickness good novel mantle woofer for equipment that television set, computer etc. has a sound equipment.
In order to realize above-mentioned purpose, can adopt following technical scheme: the basic structure of the mantle woofer of this programme is with the different of existing panel speaker, replaced rigid plate diaphragm with a whippy plane flexible plastics vibrating diaphragm, in other words, the mantle loud speaker is the electrodynamic loudspeaker that has replaced conical diaphragm with a whippy plane flexible plastics vibrating diaphragm.Therefore, except that vibrating diaphragm, its agent structure is similar to electrodynamic loudspeaker.
Specifically, loud speaker of the present utility model is the same with electrodynamic loudspeaker comprise the magnetic conductor of the magnet that contains annular and annular magnetic circuit system, contain the pelvis of columnar speech coil framework, voice coil loudspeaker voice coil, retainer spring plate and vibration of diaphragm system and inverted cone surface shape, its improvement is:
Said vibrating diaphragm is one and has favorable elasticity, circular flat soft plastic film that this vibrating diaphragm is fixed on the vibrating diaphragm frame of an annular, so constituted the vibrating diaphragm of single resonance point; The thickness of vibrating diaphragm can be selected according to the size of loud speaker and designed frequency between 0.01-3 millimeters;
Said retainer spring plate is positioned at suitable distance below the vibrating diaphragm, is used for limiting the vibration of diaphragm amplitude;
The upper surface of said pelvis and retainer spring plate are assembled together, and the last plane of lower surface and magnetic conductor is assembled together;
Said speech coil framework is fixed in the medium pore of retainer spring plate, and its upper end is connected with vibrating diaphragm, twines voice coil loudspeaker voice coil on the cylindrical of lower end; This voice coil loudspeaker voice coil also is arranged in the core hole of magnetic conductor;
Said magnet places the following of magnetic conductor and is assemblied on the magnet carrier, and the center of this magnet carrier is provided with the cylinder of a projection, and this cylinder stretches in the hole of speech coil framework.
Further, a plurality of connection ribs can also be set between vibrating diaphragm frame and pelvis, thereby the two is connected as a single entity.
Further, can be fixed with the frequency division ring of one or more rigidity on the one or more concentric circless in said vibrating diaphragm; Perhaps,
Also can be provided with the frequency division district of different-thickness on one or more concentric circless in said vibrating diaphragm, this frequency division district thickeies district by district from cylindrical to the center of circle of vibrating diaphragm, thereby form the vibrating diaphragm of multiple resonance points, make loud speaker that consistent relatively response force be arranged in the low-frequency range of 20Hz-500Hz.
The beneficial effects of the utility model are:
1, the magnetic circuit system of this mantle loud speaker is more much smaller than the diameter of vibrating diaphragm, thereby the bore of vibrating diaphragm just can be done big more much than ventional loudspeakers, this just lays a good foundation for the downward extension of low frequency, therefore, the mantle loud speaker is not needing under the audio amplifier state, also can reduce bass effect comprehensively, realize the no audio amplifierization of bass and supper bass.Like this, just can do very thinly with the stereo set that the mantle loud speaker is made, not only improved bass tonequality, reduced the cost of stereo set, alleviated weight, instant packed and transportation, and reduced usage space, especially in today of ultra-thinization of video equipment, the meaning of ultra-thinization of stereo set is more great.
2, since on vibrating diaphragm, can increase the frequency division ring or even the frequency division district, thereby form the vibrating diaphragm of multiple resonance points, make loud speaker that consistent relatively response force all be arranged in the different low-frequency ranges of 20Hz-500Hz, thereby tonequality improved greatly.
3, loadspeaker structure of the present utility model is simple, and is cheap for manufacturing cost, in the equipment applicable to various band audio frequency.
In order to make the utility model be convenient to understand, it is described further below by drawings and Examples with more clear.
