Abstract
The utility model discloses an ultrathin loudspeaker structure which comprises an iron sheet whose section is T-shaped, a bracket arranged in front side of the iron sheet, a coil which is arranged in the bracket and wound on the convex portion of the iron sheet and a plastic film encapsulated on the bracket, wherein the center of the plastic film is provided with a depressed portion, a strong magnetic powder layer is coated in the depressed portion, the total thickness of the iron sheet, the bracket and the plastic film is 0.5-2 mm, and the bracket, the plastic film and the strong magnetic layer are circular or square. As the coil is arranged in the bracket, and the strong magnetic powder layer is coated in the depressed portion on the center of the plastic film, the thickness of the loudspeaker is equal to the sum of the thicknesses of the iron sheet, the bracket and the plastic film, therefore, the volume gets smaller, and the thickness is ultra-thin.
Description
Technical field
The utility model relates to a kind of loadspeaker structure, is specifically related to a kind of loud speaker that can be used for sources of sound such as ultra thin handset, MP3, MP4.
Background technology
Along with development of electronic technology, the raising of people's living standard, the multifunction electronic product as: the product that mobile phone, MP3, MP4, mini audio amplifier etc. have the function of playing sound becomes family or the indispensable articles for daily use of individual rapidly, along with growth in the living standard, people have higher requirement to the profile of digital products such as mobile phone, MP3, MP4, the compact trend that becomes development of digital product, ultra-thinization of complete machine also require loud speaker to become littler, thinner under the condition that guarantees tonequality.
The utility model content
The purpose of this utility model just provides the extremely low loud speaker of a kind of smaller volume, thickness.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of ultrathin loudspeaker structure, comprise the cross section be the T type iron plate, be located at the iron plate front support, be positioned at the support inward turning around the coil of iron plate protuberance and be encapsulated in plastic film on the support, described plastic film center is provided with depressed part, is coated with strong magnetic blow out coating in this depressed part.
The thickness of described iron plate, support and plastic film adds up to 0.5-2mm.
Described support, plastic film, strong magnetic blow out coating are circular or square.
The beneficial effects of the utility model are: because coil is positioned at support, strong magnetic blow out coating is coated on the depressed part at plastic film center, so the thickness of loud speaker is iron plate, support and plastic film thickness sum, so smaller volume, and thickness is low to moderate 0.5-2mm.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cutaway view of A-A direction among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to Fig. 1, shown in Figure 2, a kind of ultrathin loudspeaker structure, comprise the cross section be the T type iron plate 1, be located at iron plate 1 front support 2, be positioned at support 2 inward turnings around the coil 3 of iron plate 1 protuberance and be encapsulated in plastic film 4 on the support 2, described plastic film 4 centers are provided with depressed part, be coated with strong magnetic blow out coating 5 in this depressed part, the top end face and plastic film 4 flush of strong magnetic blow out coating 5, wherein, support 2, plastic film 4, strong magnetic blow out coating 5 both can be circle, also can be squarely, the thickness of described iron plate 1, support 2 and plastic film 4 adds up to 0.5-2mm.
The utility model is because coil 3 is positioned at support 2, and strong magnetic blow out coating 5 is coated on the depressed part at plastic film 4 centers, so the thickness of loud speaker is iron plate 1, support 2 and plastic film 4 thickness sums, so smaller volume, and thickness is extremely low.
The foregoing description is illustrative principle of the present utility model and effect thereof only; and the embodiment of part utilization; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
