Abstract
The invention discloses an easily installed and detached small-scale dustproof speaker comprising a cone frame, a magnetic circuit system installed on the cone frame and a cone. The magnetic circuit system comprises a support, a magnet and a spring gasket; the magnet and the spring gasket are provided with inner holes, the middle of the support is concave inwardly to form a protrusion, the outer diameter of the protrusion is consistent to the diameter of an inner hole, the magnet and the spring gasket are in interference fitting with the protrusion, and a partitioning film is arranged on the outer side of the protrusion; a voice coil is inserted into the partitioning film, the lower end is connected to the spring gasket, and the upper end is connected to the cone. The speaker has the advantages that the defects of the prior art are overcome, design is simple, structure is reasonable, assembling is easy and stable, assembling efficiency is high, the gyromagnetic concentricity is high, cost is low, and the defective rate is low.
Description
Technical field
The present invention relates to small-bore loudspeaker technical field, specifically belong to a kind of small-sized dust-proof loudspeaker being convenient to remove and install.
Background technology
Loudspeaker are loud speaker again, be a kind of very conventional electro-acoustic transducer device, divide moving-coil type (electrodynamic type), condenser type (electrostatic), piezoelectric type (crystal or pottery), electromagnetic type (compressed spring type), electric ion type and pneumatic type loudspeaker etc. by transducing mechanism and structure.The most common most typical be that cone formula loudspeaker are also called moving-coil type loudspeaker it is made up of three parts: 1. vibrational system, comprise taper cone, voice coil loudspeaker voice coil and centring disk etc.; 2. magnetic circuit system, comprises adopted magnet, magnetic conductive board and field stem etc. forever; 3. auxiliary system, comprises support, terminal block, flanging and dust cap etc.When being in the voice coil loudspeaker voice coil in magnetic field and having tone currents to pass through, just produce the magnetic field with tone currents change, the magnetic field of this magnetic field and permanent magnet interacts, and voice coil loudspeaker voice coil is axially vibrated, because horn structure is simple, bass is plentiful, tonequality is soft, bandwidth, but efficiency is lower.
Existing loudspeaker, the washer that magnetic after-tacks glue water type is arranged on the left side of magnet, the inner bottom surface of horn bracket and the right side of magnet directly fastens with glue.It is complicated that this magnetic after-tacks glue water type support assembly technology, and cost is high, and the dust of glue in dry run in easy absorbed air, formed thread, cause fraction defective high; In addition, easily cause magnetic to return concentricity in adhesive process partially askew inaccurate, and due to gluing fastness not enough, cause voice coil loudspeaker voice coil easily to produce noise in magnetic gap motion process, fraction defective promotes.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of small-sized dust-proof loudspeaker being convenient to remove and install, overcome the deficiencies in the prior art, simplicity of design, rational in infrastructure, assembling is simple, firm, efficiency is high, magnetic returns good concentricity, and cost is low, the loudspeaker that fraction defective is low.
The technical solution used in the present invention is as follows:
A kind of small-sized dust-proof loudspeaker being convenient to remove and install, comprise frame, be installed on magnetic circuit system in frame and sound basin, described magnetic circuit system comprises support, magnet and spring shim, described magnet and spring shim are respectively with endoporus, described mid-stent caves inward into projection, the external diameter of this projection is identical with the diameter of described endoporus, described magnet is connected with described projection interference with spring shim, packing film is provided with outside described projection, described voice coil loudspeaker voice coil inserts on packing film, lower end is connected with spring shim, and upper end connects sound basin.
The center of described sound basin is provided with dust cap, and is positioned at the top of voice coil loudspeaker voice coil.
The thickness of described mid-stent is less than the thickness on described both sides.
Described frame open side be also provided with a flanging, to limit the movement position of sound basin, guarantee that sound basin moves up and down better.
Compared with the prior art, beneficial effect of the present invention is as follows:
The present invention, by voice coil loudspeaker voice coil lower end linking springs pad, makes voice coil loudspeaker voice coil and sound basin have good linear working characteristic, reduces the nonlinear distortion of sound basin motion, makes loudspeaker have the service behaviour of high efficiency, high-fidelity; The assembling of its horn structure is simple, firm, efficiency is high, and magnetic returns good concentricity, and cost is low, the loudspeaker that fraction defective is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
See accompanying drawing, a kind of small-sized dust-proof loudspeaker being convenient to remove and install, comprise frame 1, be installed on the magnetic circuit system in frame 1 and sound basin 2, described magnetic circuit system comprises support 3, magnet 4 and spring shim 5, described magnet 4 and spring shim 5 are respectively with endoporus, projection 301 is caved inward in the middle part of described support 3, the external diameter of this projection 301 is identical with the diameter of described endoporus, described magnet 4 is connected with the interference of described projection 301 with spring shim 5, packing film 6 is provided with outside described projection 301, described voice coil loudspeaker voice coil 7 inserts on packing film 6, lower end is connected with spring shim 5, upper end connects sound basin 2, the center of described sound basin 2 is provided with dust cap 8, and be positioned at the top of voice coil loudspeaker voice coil, the thickness of described mid-stent is less than the thickness on described both sides.Described frame open side be also provided with a flanging 9, to limit the movement position of sound basin, guarantee that sound basin moves up and down better, by voice coil loudspeaker voice coil lower end linking springs pad, voice coil loudspeaker voice coil and sound basin is made to have good linear working characteristic, reduce the nonlinear distortion of sound basin motion, make loudspeaker have the service behaviour of high efficiency, high-fidelity; The assembling of its horn structure is simple, firm, efficiency is high, and magnetic returns good concentricity, and cost is low, the loudspeaker that fraction defective is low.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection range is defined by appending claims and equivalent thereof.
