Abstract
The invention discloses a thin moving-coil loudspeaker, which comprises a conical cone stand, a magnetic bowl which is fixedly arranged at the bottom part of the conical cone stand, a magnet which is fixedly arranged in the center of the magnetic bowl, a paper cone with the outer periphery which is fixedly connected with an opening of the cone stand, a voice coil which is formed by a conducting wire which is wound on a cylindrical skeleton, and a centering disk, wherein the paper cone comprises a folding ring which is fixedly connected with the cone stand, a paper cone conical part which is fixedly connected with the folding ring and an inner spherical surface which is integrally formed with the paper cone conical part and protrudes outwards. A through hole is formed in the top part of the inner spherical surface to fixedly connect the inner spherical surface with a voice coil bobbin. The thin moving-coil loudspeaker has the advantages that since the single-depth paper cone is changed to be a folded structure, the acoustic performance can be realized by the paper cone with the same depth but the thickness is approximately halved and the space demand of the paper cone is greatly reduced; since the folded inner spherical surface can also provide enough travel sharing for the action of the voice coil, the space thickness demand of the voice coil is further reduced.
Description
Technical field
The present invention relates to loud speaker field, particularly a kind of coil-moving speaker of effective its thickness of reduction.
Background technology
Loud speaker is a kind of very conventional electro-acoustic transducer device, Figure 1 shows that the basic structure schematic diagram of the coil-moving speaker of prior art.As shown in Figure 1, existing coil-moving speaker comprises taper basin frame 1, be fixedly installed the magnetic conductor bowl 3 of taper basin frame 1 bottom, be arranged on the magnet 2 of magnetic conductor bowl center, be arranged on the magnetic conductive board 4 at magnet 2 tops, the taper cone 5 that outer peripheral edges are fixedly connected with basin frame opening, described taper cone center is fixedly connected with cylindrical skeleton, on described cylindrical skeleton, by a wire, be wound around and form voice coil loudspeaker voice coil 7, also comprise outer end and the inner centring disk 6 that is fixedly connected with basin frame and cylindrical skeleton respectively and can spacing described cylindrical skeleton moves both vertically up and down simultaneously, wherein, between described magnetic conductive board and magnetic conductor bowl, form the uniform magnetic gap of a circle, the winding of voice coil loudspeaker voice coil is partly symmetrical in magnetic gap and arranges.
During moving-coil speaker work, the wire of voice coil loudspeaker voice coil winding has electric current to pass through, and according to left hand rule, the winding in magnetic gap can produce the power conforming to direction with the current strength of flowing through and promote cone motion.Because centring disk and cone are movabilities on the direction of vibration of cone, but have very large rigidity in the direction vertical with direction of vibration, guarantee voice coil loudspeaker voice coil winding part can be in magnetic gap proper motion and deflection does not occur.
The electronic products such as television set are one of topmost fields of coil-moving speaker application, television display screen upgrades to LED by CRT, LCD at present, television screen is more and more thinner, there is the condition that television screen is thin, it is very thin that the profile of television set just can be done, to the thickness requirement of loud speaker, be also to get over Bao Yuehao, and in thin, guarantee again the acoustic performance of loud speaker, this just needs a kind of novel loud speaker.
Summary of the invention
Technical purpose of the present invention is the shortcoming that overcomes prior art, and a kind of slim coil-moving speaker that can effectively reduce thickness is provided.
For realizing above-mentioned technical purpose, the technical solution adopted in the present invention is:
A kind of slim coil-moving speaker, comprise taper basin frame, be fixedly installed the magnetic conductor bowl of taper basin frame bottom, the fixedly magnet, the cone that outer peripheral edges are fixedly connected with basin frame opening of magnetic conductor bowl center, by a wire, be wrapped in voice coil loudspeaker voice coil and the centring disk forming on cylindrical skeleton, wherein, described cone comprises the ring being fixedly connected with basin frame, the cone conical section being fixedly connected with ring and being integrally formed with cone conical section and outside outstanding Internal Spherical Surface, described Internal Spherical Surface top is formed with through hole to be fixedly connected with described speech coil framework.
Described centring disk is waveform ring, and its outer rim is fixedly connected with basin frame, and inner edge is fixedly connected with the intersection point of cone conical section and Internal Spherical Surface.
It is inner that described magnetic conductor bowl is fixedly installed on basin frame.
Described basin frame base plate center is formed with through hole, and expose outside described base plate described magnetic conductor bowl lower end.
With respect to prior art, beneficial effect of the present invention:
The present invention changes into bendable structure by the single degree of depth of cone, the acoustic performance that the same cone degree of depth can realize and thickness reduce near half, greatly reduced the requirement of cone to space, the Internal Spherical Surface of simultaneously turning back is also for the action of voice coil loudspeaker voice coil provides enough strokes to share, further reduce voice coil loudspeaker voice coil to space thickness demand, simultaneously centring disk and basin frame are fixedly connected with and are positioned at the minimum point of cone, can effectively stablize the direction of motion of voice coil loudspeaker voice coil with raising tonequality.
Accompanying drawing explanation
Figure 1 shows that the basic structure schematic diagram of the coil-moving speaker of prior art;
Figure 2 shows that the basic structure schematic diagram of slim coil-moving speaker of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
Figure 2 shows that the basic structure schematic diagram of slim coil-moving speaker of the present invention.As shown in Figure 2, slim coil-moving speaker of the present invention comprises the taper basin frame 10 consisting of tapered sidewalls and base plate, be fixedly installed the magnetic conductor bowl 11 on the base plate of taper basin frame bottom, the fixing magnet 12 of magnetic conductor bowl center, the cone 13 that outer peripheral edges are fixedly connected with basin frame opening, by a wire, be wrapped in voice coil loudspeaker voice coil and the centring disk 15 forming on cylindrical skeleton 14, wherein, described cone comprises the ring 131 being fixedly connected with basin frame, the cone conical section 132 being fixedly connected with ring and being integrally formed with cone conical section and outside outstanding Internal Spherical Surface 133, described Internal Spherical Surface top is formed with through hole to be fixedly connected with described speech coil framework.Wherein, described centring disk is waveform ring, and its outer rim is fixedly connected with basin frame, and inner edge is fixedly connected with the intersection point of cone conical section and Internal Spherical Surface.Certainly, also can be fixedly installed at skeleton top dust cover 19, described dust cover is fixedly connected with skeleton bonding, and the through hole of described Internal Spherical Surface is fixedly connected with dust cover bonding, and this kind of connected mode can realize the present invention's object equally.
The present invention changes into bendable structure by the single degree of depth of cone, the acoustic performance that the same cone degree of depth can realize and thickness reduce near half, greatly reduced the requirement of cone to space, the Internal Spherical Surface of simultaneously turning back is also for the action of voice coil loudspeaker voice coil provides enough strokes to share, further reduce voice coil loudspeaker voice coil to space thickness demand, simultaneously centring disk and basin frame are fixedly connected with and are positioned at the minimum point of cone, can effectively stablize the direction of motion of voice coil loudspeaker voice coil with raising tonequality.
