Abstract
The utility model discloses a loudspeaker. The loudspeaker comprises a shell, a magnetic circuit system and a vibration system. The vibration system comprises a vibrating diaphragm and a voice coil. The loudspeaker also comprises a pressing piece used for arranging the vibrating diaphragm on the shell. The pressing piece comprises a fixing portion which is connected to the shell through ultrasonic welding and a compaction portion which compresses the vibrating diaphragm on the shell. A compaction portion surface is provided with a raised clamping portion. Because the ultrasonic welding pressing piece is used to compress the vibrating diaphragm on the shell, a problem that vibrating diaphragm which is made of a material with low surface energy is easy to fall off is solved. Because the loudspeaker does not use glue to carry out pasting, the loudspeaker is safe and environment friendly compared with a loudspeaker made by a traditional technology.
Description
Technical field
the utility model relates to a kind of loud speaker.
Background technology
when loud speaker assembling, conventionally vibrating diaphragm is combined with housing, generally all adopt glue that vibrating diaphragm and housing are bonded together, when glue volatilization, sovent diffusion has arrived in air, can cause certain influence to direct labor's health, also can affect surrounding environment simultaneously, and in the time that vibrating diaphragm belongs to low-surface-energy material, glue is difficult for sticking together, and in the time of speaker operation, the high-frequency vibration of vibrating diaphragm easily makes vibrating diaphragm come off from housing.
Summary of the invention
the purpose of this utility model is to provide the loud speaker of a kind of Environmental Safety and vibrating diaphragm difficult drop-off.
for achieving the above object, the technical solution adopted in the utility model is: a kind of loud speaker, it comprises housing, magnetic circuit system, vibrational system, described vibrational system comprises vibrating diaphragm, voice coil loudspeaker voice coil, it also comprises for described vibrating diaphragm is arranged on to the briquetting on described housing, described briquetting comprises the fixed part being connected with described housing by ultra-sonic welded, the compressed part that described vibrating diaphragm is pressed on to described housing, and described compressed part surface is provided with protruding card division.
preferably, the cross section of described card division is triangle.
preferably, described card division is the annular protrusion along the edge distribution of described vibrating diaphragm.
further preferably, described card division is provided with twice.
because technique scheme is used, the utility model compared with prior art has following advantages:
because the utility model adopts the briquetting of ultra-sonic welded, vibrating diaphragm is pressed on housing, has solved the vibrating diaphragm that the low material of surface energy makes and held caducous problem, because the utility model is without adopting glue to paste, relatively and the safer environmental protection of traditional handicraft.
Brief description of the drawings
accompanying drawing 1 is schematic diagram of the present utility model;
accompanying drawing 2 is the utility model partial enlarged drawing A.
in above accompanying drawing: 1, housing; 2, vibrating diaphragm; 3, briquetting; 31, fixed part; 32, compressed part; 33, card division; 4, hot melt wire.
Embodiment
below in conjunction with embodiment shown in the drawings, the utility model is further described:
embodiment mono-: shown in accompanying drawing 1-2, a kind of loud speaker, it comprises housing 1, magnetic circuit system, vibrational system, described vibrational system comprises vibrating diaphragm 2, voice coil loudspeaker voice coil, it also comprises for described vibrating diaphragm 2 is arranged on to the briquetting 3 on described housing 1, described briquetting 3 comprises the fixed part 31 being connected with described housing 1 by ultra-sonic welded, the compressed part 32 that described vibrating diaphragm 2 is pressed on to described housing 1, described compressed part 32 surfaces are provided with protruding card division 33, between described fixed part 31 and described housing 1, be provided with hot melt wire 4, the cross section of described card division 33 is triangle.
described card division 33 is the annular protrusion along the edge distribution of described vibrating diaphragm 2, and described card division 33 is provided with twice.
because the present embodiment adopts the briquetting 3 of ultra-sonic welded, vibrating diaphragm 2 is pressed on housing 1, has solved the vibrating diaphragm 2 that the low material of surface energy makes and held caducous problem, because the present embodiment is without adopting glue to paste, relatively and the safer environmental protection of traditional handicraft.
above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection range of the present utility model.
