Abstract
The utility model discloses a speaker in a multi-diaphragm structure, which comprises a frame and diaphragms. A first step, a second step and a frame bottom are sequentially arranged on the frame from top to bottom, and a magnet and a voice coil are arranged inside the frame bottom. The diaphragms includes a first diaphragm and a second diaphragm, a suspension edge of the first diaphragm is arranged on the first step, a suspension edge of the second diaphragm is arranged on the second step, the suspension edges of the first diaphragm and the second diaphragm are dampers, and the first diaphragm and the second diaphragm are mutually combined. Mutual combination of the first diaphragm and the second diaphragm, and the suspension edges as the dampers improve stability of vibration of different frequencies generated when sound passes a magnetic field in the form of current due to changes of the strength of the current. Secondarily, a cone in the middle of the second diaphragm can provide sufficient space for containing a loop of the magnetic field, thereby the vibration amplitude and the vibration space of the speaker are increased, and the efficiency of the speaker is also enhanced.
Description
Technical field
The utility model relates to the loud speaker art, refers in particular to a kind of loud speaker of multiple bulging paper structure.
Background technology
At present, along with The development in society and economy, people's standard of living promotes day by day, for the quality of recreation and require also gradually towards exquisiter direction, and the auditory effect of sound, the visible change of light, also all to become the indispensable project that promotes quality of the life, especially the emphasis of the general especially leisure of sound (music), good and suitable music, for loosening mood, eliminate the nervous splendid effect that has, therefore, Xiang Guan acoustic product is a feast for the eyes especially on the market, and it is formal confused to make us dim eyesight, and in above-mentioned acoustic product, the function that the current signal of enlarger output is converted to sound is being born by loud speaker system, and its overall sound quality output quality for sound equipment has decisive influence.The cardinal principle of loud speaker is to combine with the pronunciation source with a magnetic circuit device, and it produces changes of magnetic field, so drive loud speaker voice coil loudspeaker voice coil, play ripple, the vibration of drum paper to produce sound.
Yet in vogue day by day along with on the market LCD, OLED product, cause household electrical appliance also progressively to move towards lightening, though existing loudspeaker structure also can be accomplished to a certain degree lightening, but its structure still is subjected to great restriction, cause its amplitude little, defectives such as stability of vibration is poor, and power is low, and sound press is low.
The utility model content
The utility model is at the disappearance of prior art existence, and its main purpose provides a kind of loud speaker of multiple bulging paper structure, makes its vibration more stable;
Another purpose of the present utility model provides a kind of loud speaker of multiple bulging paper structure, and it has bigger amplitude, higher power, higher sound press.
For achieving the above object, the utility model adopts following technical scheme:
A kind of loud speaker of multiple bulging paper structure, include basin frame, drum paper, the basin frame has at the bottom of first step, second step and the basin from the top down successively, be provided with magnet, voice coil loudspeaker voice coil at the bottom of the basin, this drum paper has the first drum paper and the second drum paper, and the outstanding limit of the first drum paper places on the first step, and the outstanding limit of the second drum paper places on the second step, the outstanding limit of the first drum paper and the second drum paper is for playing ripple, and the first drum paper combines with the second drum paper.
As a kind of preferred version, described second taper of drum paper for diminishing gradually from top to bottom.
As a kind of preferred version, described magnet periphery is provided with a steel bushing, and the lower end of voice coil loudspeaker voice coil is held between magnet and the steel bushing.
As a kind of preferred version, the described first drum paper is a thin sheet form, is encapsulated in basin frame top opening part.
As a kind of preferred version, the cone upper end of the described second drum paper is butted on the lower surface of the first drum paper.
As a kind of preferred version, described voice coil loudspeaker voice coil is connected with the first drum paper lower surface in the middle of being upward through the second drum paper.
The utility model compared with prior art has tangible advantage and beneficial effect, particularly, as shown from the above technical solution, by mutually combining between the first drum paper and the second drum paper, outstanding limit is for playing ripple, stability when having improved the vibration that can produce different frequency because of the variation of electric current power by magnetic field with the form of electric current when sound, secondly the cone in the middle of the second drum paper makes the sufficient room that holds field circuit can be provided, and then increased amplitude of the present utility model, improve efficient and oscillation space, and helped the variation design of field circuit.
For more clearly setting forth architectural feature of the present utility model and effect, come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment:
Description of drawings
