Abstract
The utility model relates to a technical field is made to the audio amplifier, especially relates to a loudspeaker of wear -type, which comprises a bracket body, support body middle part has the sound hole, install the chassis in the sound hole, be equipped with magnet on the chassis, magnet passes through the clamp plate to be fixed in the chassis, sound hole upper portion is equipped with three compound vibrating diaphragms, the compound membrane diameter at middle part is greater than two compound membrane diameter of both sides. The utility model discloses simple structure, because the utility model discloses a three compound vibrating diaphragms, the distortion that can the greatly reduced sound hole produces.
Description
Technical field
The utility model relates to audio amplifier manufacturing technology field, particularly relates to a kind of loudspeaker of wear-type.
Background technology
Loudspeaker can convert the electrical signal to acoustical signal and be radiated the electroacoustic transducer gone in air.The loudspeaker of traditional wear-type are divided into electrodynamic type, electromagnetic type, electrostatic, piezoelectric type, ionic formula and pneumatic type etc. by operation principle.In the loudspeaker of the wear-type of each type, using is electrodynamic type loudspeaker at most, the most widely, is also called moving-coil type loudspeaker.The vibrating diaphragm of existing wear-type loudspeaker is all monofilm, the vibrating diaphragm system of this monofilm, and when giving great volume, distortion is relatively more serious, cannot meet the demand of present young user.
Utility model content
The purpose of this utility model is the deficiency overcoming above-mentioned technology, and provides a kind of loudspeaker of wear-type, is convenient to fix, not easily distortion.
The utility model for achieving the above object, by the following technical solutions:
A kind of loudspeaker of wear-type, it is characterized in that: comprise rack body, with sound hole in the middle part of described rack body, in described sound hole, underframe is installed, described underframe is provided with magnet, described magnet is fixed in described underframe by pressing plate, and described sound hole top is provided with three composite diaphragms, and the composite diaphragm diameter at described middle part is greater than two composite diaphragm diameters of both sides.
Preferably, the both sides of described rack body are provided with sidewall, and the junction of described sidewall and rack body is provided with sizing material groove.
Preferably, be provided with vibrating diaphragm in described sizing material groove and tamp block.Vibrating diaphragm tamps block and is annular and is with flexible, after vibrating diaphragm is put into sizing material groove, can without the need to passing through glue, and directly tamp block by vibrating diaphragm and carry out compressing, vibrating diaphragm tamps block and is directly stuck in sizing material groove.
Preferably, described magnet top is provided with spacing preiection, and described pressing plate is provided with the limited impression coordinated with described spacing preiection.Spacing preiection and limited impression can limit pressing plate by cooperatively interacting and rock, more firm fixed magnet.
The beneficial effects of the utility model are: the utility model structure is simple, because the utility model adopts three composite diaphragms, greatly can reduce the distortion that sound hole produces; Come characteristic and the process technology of deisgn product by designed, designed and actual utility strategies, effectively avoid the problem in processing; By proportioning and the Shooting Technique improvement of plastic pellet, solve the problem of the dimensional accuracy of part; By high-precision integrative Combined fixture technology, effectively solve Product Assembly efficiency and precision problem; By Optimal Structure Designing, make the magnetic circuit gap of product little, ensure that product distortion is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1, a kind of loudspeaker of wear-type, comprise rack body 1, with sound hole 2 in the middle part of described rack body, be provided with underframe 3 in described sound hole, described underframe is provided with magnet 4, and described magnet is fixed in described underframe by pressing plate 5, described sound hole top is provided with three composite diaphragms 6, and the composite diaphragm diameter at described middle part is greater than two composite diaphragm diameters of both sides.The both sides of described rack body are provided with sidewall 7, and the junction of described sidewall and rack body is provided with sizing material groove 8.Sizing material groove is for placing sizing material, and it is more firm that sizing material can make composite diaphragm fix.
Be provided with vibrating diaphragm in described sizing material groove and tamp block.Vibrating diaphragm tamps block and is annular and is with flexible, after vibrating diaphragm is put into sizing material groove, can without the need to passing through glue, and directly tamp block by vibrating diaphragm and carry out compressing, vibrating diaphragm tamps block and is directly stuck in sizing material groove.Described magnet top is provided with spacing preiection, and described pressing plate is provided with the limited impression coordinated with described spacing preiection.Spacing preiection and limited impression can limit pressing plate by cooperatively interacting and rock, more firm fixed magnet.
The utility model structure is simple, because the utility model adopts three composite diaphragms, greatly can reduce the distortion that sound hole produces; Come characteristic and the process technology of deisgn product by designed, designed and actual utility strategies, effectively avoid the problem in processing; By proportioning and the Shooting Technique improvement of plastic pellet, solve the problem of the dimensional accuracy of part; By high-precision integrative Combined fixture technology, effectively solve Product Assembly efficiency and precision problem; By Optimal Structure Designing, make the magnetic circuit gap of product little, ensure that product distortion is low.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
