Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
- 5 are please referred to Fig.1, a kind of integrated casing loudspeaker, including hollow shell 1, magnet 2, sound film combine 3, shielding case
4, circuit board 5, lead 6 and T iron 7, the central integrated setting T iron 7 of shell 1,1 integrated setting of T iron 7 and shell, integration
It is firm that shell more consolidates, and magnet 2 is installed in the inner cavity of shell 1, and magnet 2 is also configured as and 1 internal diameter size one of integrated casing
It causes, glue need not be used when installation, is directly put into magnet 2, the internal diameter and magnet 2 one of integrated casing 1
It causes, will not shift, in addition the inner ring and outer ring of magnet 2 can be all sucked due to 2 suction of magnet, and it is by the outer of shell 1 that magnet 2, which is fixed,
It encloses directly fixed with the interior shell enclosed, will not be deviated using product due to long-time not against glue, entire T iron 7, shell 1, magnet
2 installation need not use glue, need not also be fixed using jig, and T iron 7 passes through magnet 2, the top of magnet 2 to install sound
Film combination 3, sound film combination 3 includes copper ring 31, vibrating diaphragm 32 and fixed cylinder 33, and the centre of copper ring 31 is fixedly connected with fixed cylinder 33, Gu
Safety barrel 33 is sleeved on magnet 2, and vibrating diaphragm 32 is connected on copper ring 31, and copper ring 31 is connect with magnet 2, the peripheral copper ring 31 of sound film combination 3,
Copper ring 31 has certain height, can keep apart magnet 2 and vibrating diaphragm 32 when being mounted directly, copper ring 31 and shell 1
Inner wall be adjacent to, fixed with shell 1 and magnet 2 convenient for fixed, shielding case 4, the top installation electricity of shielding case 4 be installed on copper ring 31
