Abstract
The utility model relates to the technical field of electro-acoustic products, and provides a loudspeaker module. The loudspeaker module comprises a loudspeaker single body and a housing for accommodating the loudspeaker single body. The housing includes an upper housing and a lower housing which are combined together. Multiple positioning columns are disposed between the upper housing and the lower housing. The positioning columns and the upper housing form an all-in-one structure. Positioning sleeves are disposed at positions on the lower housing corresponding to the positioning columns. The positioning sleeves sleeve the positioning columns. An end portion of each positioning column is provided with an ultrasonic wire. The positioning columns and the positioning sleeves are welded together through ultrasonic bonding. The upper housing and the lower housing are welded together through ultrasonic bonding. The loudspeaker module can effectively prevent the upper housing and the lower housing from vibrating along with the airflow vibration in an internal cavity of the loudspeaker module and prevent noise generation, and thus the acoustic performance of the loudspeaker module is improved.

The utility model is to realize like this, a kind of loud speaker module, comprise loudspeaker monomer and for accommodating the housing of described loudspeaker monomer, described housing comprises the upper casing and the lower casing that combine, between described upper casing and described lower casing, be provided with multiple reference columns, described reference column and described upper casing are integral type structure, on described lower casing, just the position to described reference column is provided with positioning sleeve, described reference column is sheathed in described positioning sleeve, the end of described reference column is provided with ultrasound lines, and described reference column is together with the ultra-sonic welded of described positioning sleeve bottom; Described upper casing is together with described lower casing ultra-sonic welded.
As a kind of improved plan, on described upper casing, just the position to described loudspeaker monomer offers through hole, and is embedded with metal insert in described through hole.
As a kind of improved plan, on described metal insert, punch forming has reinforcement.
As a kind of improved plan, described reinforcement is provided with multiple.
The loud speaker module that the utility model provides, owing to being provided with multiple reference columns between its upper casing and lower casing, and reference column and upper casing are integral type structure, and on lower casing just the position to reference column be provided with positioning sleeve, then reference column is sheathed in positioning sleeve, adopt this kind of structure, increase the support fixing point between upper casing and lower casing, and use the mode of ultra-sonic welded between reference column and positioning sleeve and between upper casing and lower casing, to combine, upper casing also can make together with can effectively and firmly fix with lower casing, effectively avoid upper casing and lower casing self to vibrate with the airstream vibration in loud speaker module inner chamber, prevent the generation of noise, improve the acoustical behavior of this loud speaker module.
