Abstract
The utility model relates to a loudspeaker in the electroacoustical industry. Two ring permeablility magnetic materials (2) and (21) are utilized to adhere to the upper and the lower end surfaces of a magnet (4) to form a peripheral magnetic circuit. Two pieces of ring permeablility magnetic materials (9) and (91) are utilized to adhere to one end surface of two magnets (10) and (11), and the middle of two magnets (10) and (11) is adhered by a permeablility magnetic material (6), the height is matched with the peripheral magnetic circuit to form a middle magnetic circuit. Through a speech coil (5) (wherein, one group of windings has reverse direction), the middle magnetic circuit makes synchronized motion in the two magnetic circuit, and drives a speech basin (1) to make up-and-down movement, thereby greatly improving the efficiency and the sensitivity of the loudspeaker. At the same time, the upper and the bottom of the loudspeaker both adopt locating support chips (3) and (13), thereby strengthening the rigidity of a vibration system to ensure that the speech coil (5) makes more even vertical motion in the magnetic field, and greatly improving the bearing power of the loudspeaker.
Description
The utility model relates to a kind of electro-acoustic product, refers to the loud speaker in the electroacoustic industry especially.
For a long time, ventional loudspeakers utilizes two permeability magnetic materials to be bonded in the upper and lower end face of magnet, produce a magnetic field in the working region of voice coil loudspeaker voice coil, tone currents produces cutting movement by voice coil loudspeaker voice coil (electrified wire) in magnetic field, drives the sound basin and produces up-down vibration, in air, form the density ripple, pass to people's ear (generation sound), be characterized in forming a magnetic circuit, utilize the single-tone circle, unidirectional locating branch slice, thereby can't satisfy high sensitivity, the needs of supersound projector.
The purpose of this utility model provide a kind of highly sensitive, bear high-power loud speaker.
For reaching above-mentioned purpose, the utility model scheme is such: an annular permeability magnetic material at first fixes with screw with the basin frame, bonded permanent magnet and another annular permeability magnetic material again, thus form peripheral magnetic circuit; Two annular permeability magnetic materials are bonding with an end face of two magnets respectively, and the permeability magnetic material height of middle bonding and the height of peripheral magnetic circuit are complementary, thus magnetic circuit in the middle of forming, and this assembly is fixed on the back cover with screw; Fix a locating branch slice on the permeability magnetic material of the lower end of peripheral magnetic circuit, bonding with voice coil loudspeaker voice coil, it is bonding to fix another locating branch slice and voice coil loudspeaker voice coil on the basin frame, and two groups of coil direction of this voice coil loudspeaker voice coil are opposite.
Size is identical because such scheme forms two but two magnetic circuits that direction is opposite, by voice coil loudspeaker voice coil (wherein one group of coil direction is opposite) being synchronized with the movement at two magnetic circuits, and driving the sound basin moves up and down, thereby greatly improved the efficient of loud speaker, produced the ventional loudspeakers sensitivity that is beyond one's reach, simultaneously, owing on peripheral magnetic circuit lower end and basin frame, all adopted locating branch slice, thereby strengthened the rigidity of system, it is more even that voice coil loudspeaker voice coil is moved both vertically in magnetic field, more accurate, thus the power that bears of loud speaker greatly improved.
Below in conjunction with accompanying drawing and embodiment the utility model loud speaker is described further.
Fig. 1 is the center section plan of the utility model loud speaker
As seen from the figure:
Ring shaped conductor material (2) links to each other with basin frame (7) with screw, and magnet (4) bonds with glue, thereby forms peripheral magnetic circuit with permeability magnetic material (2), (2 '); Annular permeability magnetic material (9), (9 ') bond respectively with two magnets (10), (11) outer end respectively, and are middle bonding with glue with permeability magnetic material (6), thus magnetic circuit in the middle of forming, and this assembly is fixed on the back cover (10) with screw; Plastic ring (12) is connected with screw with permeability magnetic material (2 '), locating branch slice (3) and sticking plaster (12), voice coil loudspeaker voice coil (5) bonding, and locating branch slice (13) bonds with basin frame (7), voice coil loudspeaker voice coil (5) respectively simultaneously.
The height of permeability magnetic material (6) and peripheral magnetic circuit height are complementary.Two groups of coil direction of voice coil loudspeaker voice coil (5) are opposite.
Claims (2)
1, a kind of loud speaker, comprise sound basin (1), permeability magnetic material (2), locating branch slice (3), magnet (4), voice coil loudspeaker voice coil (5), basin frame (7), back cover (8) etc., basin frame (7) is connected with screw with back cover (8), ring shaped conductor material (2) links to each other with basin frame (7) with screw, magnet (4) and permeability magnetic material (2), (2 ') bond with glue, thereby form peripheral magnetic circuit, it is characterized in that: annular permeability magnetic material (9), (9 ') respectively with two magnets (10), (11) end face bonds respectively, middle bonding with glue with permeability magnetic material (6), thereby magnetic circuit in the middle of forming, this assembly is fixed on the back cover (10) with screw; Plastic ring (12) is connected with screw with permeability magnetic material (2 '); Locating branch slice (3) and plastic ring (12), voice coil loudspeaker voice coil (5) bonding, locating branch slice (13) bonds with basin frame (7), voice coil loudspeaker voice coil (5) respectively simultaneously.
2, loud speaker as claimed in claim 1 is characterized in that: the height of permeability magnetic material (6) and peripheral magnetic circuit height are complementary.
