Abstract

The utility model discloses an improve glued miniature loudspeaker module group, include epitheca, inferior valve, miniature speaker monomer, draw forth the FPCB board, be provided with in the epitheca with speaker monomer appearance assorted fixed slot, fixed slot bottom border is equipped with the closed assembly bench terrace of non -, fender wall one side that the assembly bench terrace is being close to the fixed slot is provided with the inside sunken gluey groove of depositing, the cavity that epitheca and inferior valve enclose is arranged in to the speaker monomer, the speaker monomer is drawn forth to work a telephone switchboard to be connected with outside electron terminal equipment through the FPCB board and is switched on, epitheca, miniature speaker monomer, draw forth FPCB board, inferior valve fixed mounting in proper order. The utility model discloses simple structure changes few with low costsly to the current mould of making. The utility model provides a depositing gluey groove and chamfer, when miniature speaker assembles, suitably increasing adhesive spread at the assembly bench terrace, after speaker monomer assembly extrusion, unnecessary glue is partly can to flow to depositing gluey groove, and chamfer trickling downwards naturally can be followed to another part to can not overflow and glue on the speaker monomer and influence the acoustic performance of speaker, simultaneously also and solve the gluey problem of resolving, make the speaker free fix more firm.

Description

A kind of cementing Microspeaker module of improvement
Technical field
This utility model belong to Microspeaker technical field and in particular to one kind to improve Microspeaker cementing with upper casing Microspeaker module.
Background technology
Increasingly develop to the direction that becomes more meticulous with consumer electronics products such as mobile phone, flat boards, as wherein important acoustics The speaker module of part also increasingly miniaturization.Because described assembling step surface 12 width is minimum, and during gluing, require glue Amount is as far as possible few, to avoid the excessive glue after loudspeaker monomer 3 assembling to affect the acoustical behavior of speaker.Find in assembly work, In narrower gluing plane, the problem of disconnected glue often occurs, and the acoustical behavior of speaker and service life are difficult to ensure that.
Content of the invention
The technical problems to be solved in the utility model is to provide a kind of a kind of structurally simple, economical applicable improvement cementing Microspeaker module.
This utility model solves above-mentioned technical problem by the following technical programs,
A kind of cementing Microspeaker module of improvement, including upper casing, lower casing, Microspeaker monomer, draws FPCB plate, It is characterized in that,
It is provided with the fixing groove matching with loudspeaker monomer profile in described upper casing;
Described fixing groove bottom sides are along the assembling step surface being provided with non-closed;
Described assembling step surface near fixing groove retaining wall side be provided with cave inward deposit glue groove;
Loudspeaker monomer is placed in the cavity that upper casing and lower casing surround;
Described loudspeaker monomer is drawn wiring by FPCB plate and is connected conducting with external electrical terminal unit;
Described upper casing, Microspeaker monomer, extraction FPCB plate, lower casing fixedly mount successively.
As optimization, also damping screen, described damping screen is affixed on upper casing, it is to avoid upper casing is occurred with Microspeaker monomer Resonance, impact output tonequality;
As optimization, it is additionally provided with chamfering in the outside of described retaining wall.
This utility model structure is simple, changes few low cost to existing manufacture mould.This utility model provide deposit glue groove and Chamfering, when Microspeaker assembles, can suitably increase glue-spread in assembling step surface, after loudspeaker monomer assembling extruding, A unnecessary glue part can flow to deposits glue groove, and another part can trickle downwards naturally along chamfering, thus not excessive glue is to raising one's voice Affect the acoustical behavior of speaker on device monomer, simultaneously also and also solve the problems, such as to resolve glue, make the fixation of loudspeaker monomer more Plus firmly.
Brief description
Fig. 1 is this utility model embodiment exploded view;
Fig. 2 is this utility model embodiment upper case structure schematic diagram;
Fig. 3 is this utility model embodiment upper casing schematic cross-section;
Fig. 4 is this utility model embodiment partial enlarged drawing.
Specific embodiment
With reference to the accompanying drawings and examples, it is further elaborated on content of the present utility model.
A kind of cementing Microspeaker module of improvement, including upper casing 1, lower casing 2, Microspeaker monomer 3, draws FPCB Plate 4, damping screen 5,
It is provided with the fixing groove 11 matching with loudspeaker monomer 3 profile in described upper casing 1;
Described fixing groove 11 bottom sides are along the assembling step surface 12 being provided with non-closed;
Described assembling step surface 12 near fixing groove 11 retaining wall 13 side be provided with cave inward deposit glue groove 14; It is additionally provided with chamfering 15 in the outside of described retaining wall 13;
It is fixing with the gluing of loudspeaker monomer 3 that described upper casing 1 passes through gluing realization on assembling step surface 12;
Loudspeaker monomer 3 is placed in the cavity that upper casing 1 and lower casing 2 surround;
Described loudspeaker monomer 3 is drawn wiring by FPCB plate 4 and is connected conducting with external electrical terminal unit;
Described upper casing 1, Microspeaker monomer 3, extraction FPCB plate 4, lower casing 2 fixedly mount successively;
Described damping screen 5 is affixed on upper casing 1, it is to avoid upper casing 1 is resonated with Microspeaker monomer 3, impact output sound Matter.
During assembling, after glue 6 is applied and assembles on step surface 12, unnecessary a part of glue 6 can flow to be deposited in glue groove 14, Other glue 6 and naturally trickling downwards along chamfering 15, without being attached on Microspeaker monomer and then affecting miniature raising The sounding performance of sound device monomer.
This utility model structure is simple, changes few low cost to existing manufacture mould.This utility model provides and deposits glue groove 14 With chamfering 15, when Microspeaker assembles, can suitably increase glue-spread in assembling step surface, when loudspeaker monomer 3 assembling is squeezed After pressure, unnecessary glue 6 part can flow to deposits glue groove 14, and another part can trickle downwards naturally along chamfering 15, thus not Excessive glue affects the acoustical behavior of speaker on loudspeaker monomer 3, simultaneously also and also solve the problems, such as to resolve glue, make speaker list The fixation of body is more firm.
