Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and do not have to
It is of the invention in limiting.
Refering to fig. 1,2 and Fig. 4, the loudspeaker of the compact of the embodiment of the present invention include host front housing 10, motherboard 20, raise
Sound device ontology 30, sealing element 40 and host rear shell are formed between host front housing 10 and host rear shell (not shown) and are raised for placing
The sound chamber B of sound device ontology 30, motherboard 20 are located between host front housing 10 and host rear shell to the stacking of sealing element 40, and main
The avoiding area (such as notch or through-hole) passed through for loudspeaker ontology 30 is offered on machine plate 20, sealing element 40 includes the first envelope band 41
Respectively from the vertically extending second envelope band 42 in 41 both ends of the first envelope band, the first envelope band 41, the second envelope band 42 are sealed in raise respectively
Around sound device ontology 30.Wherein, host front housing 10 is a part of the shell of electronic equipment.
As shown in connection with fig. 4, the first envelope band 41 and its second envelope band 42 of two sides surround semi-enclosed sealing structure, after host
After cap closes, sealing element 40, motherboard 20 are successively pressed on host front housing 10, such simple process and low cost, occupied space
Small, the outer rim of host front housing 10 can be used as the sealing edge of wherein side, and loudspeaker ontology 30 can be produced on electronic equipment
Edge, i.e. sound chamber a frame can be made very narrow, other components can have more spaces to be arranged.Wherein,
Sealing element 40 can be the preferable sealing material of the elasticity such as foam, rubber, silica gel.
Such as Fig. 2 and Fig. 3, in order to improve sealing performance, sound chamber B is opened on host front housing 10 by the present embodiment, before host
Shell 10 be also provided with around sound chamber B surround adjacent first side on sound chamber B, second side, third side recessed portion 11,
Sealing element 40 is embedded in recessed portion 11, and the motherboard 20 being arranged on sealing element 40 is above 10 surface of host front housing.It is first
First, sealing element 40 is pasted onto the recessed portion 11 of host front housing 10, then motherboard 20 is placed on sealing element 40, finally
Host rear shell is fixed on host front housing 10, sealing element 40 is compressed reliably to be sealed.
There is the barricade 12 set on the 4th side of sound chamber B such as Fig. 2, on host front housing 10, barricade 12 includes being located at sound chamber B
The 4th side barricade main body 121 and extend respectively towards two recessed portions 11 adjacent thereto from 121 both ends of barricade main body
Corner part 122,42 end face of the second envelope band offset with barricade main body 121.12 height of barricade is higher than recessed portion 11 and sound chamber B, when close
After sealing 40 is arranged in recessed portion 11, what four sides of sound chamber B were surrounded by the first envelope band 41, the second envelope band 42 and barricade 12
Enclosed construction is sealed, and corner part 122 and barricade main body 121 surround rectangular shaped, 42 end surface shape of the second envelope band and turning
Portion 122 matches and elasticity abuts.
Here, recessed portion 11 is connected to setting with sound chamber B, and the depth of recessed portion 11 is less than sound chamber B.As shown in connection with fig. 4, it seals
42 end of the second envelope band of part 40 includes step-like notch section 420, and notch section 420 is consistent with the shape of corner part 122, and is lacked
Oral area 420 is close to corner part 122.Offer the cutting line C extended from notch section 420 on second envelope band 42, two cutting line C it
Between the second envelope band 42 be located between corner part 122 and the corresponding end face of motherboard 20.Preferably, the length of cutting line C is extremely
It is few 0.2mm longer than the height of corner part 122.During installation, first by 41 bonding partially of the first envelope band of sealing element 40 before host
On shell 10, then the second envelope band 42 of two sides is entirely fitted in recessed portion 11, tears up the second envelope band 42 along cutting line C
Inboard portion, and the inboard portion is turned down to holding up, be bonded with corner part 122, therefore host front housing 10 and motherboard 20
Sealing between end face is guaranteed.
In addition, the corner part 122 of host front housing 10 is alternatively arranged as the limiting section of motherboard 20, motherboard 20 and host front housing
The place that 10 corner part 122 cooperates also forms stair-stepping notch, and motherboard 20 can be fastened in host front housing 10 after installing
Corner part 122 is conducive to the dislocation for avoiding motherboard 20.Since barricade 12 is above recessed portion 11, sound chamber B is in 12 side of barricade
Sound and non-linear out, but stepped sound route out, are more advantageous to and the sealing means of the present embodiment cooperate raising sealing
Effect.
In other embodiments, recessed portion 11 can also be arranged with the sound interval chamber B.20 phase of corner part 122 and motherboard
Individual auxiliary sealing member also can be used in the sealing between end face answered, but since the size at this is smaller (usually deep
1mm, the wide 1mm in section), therefore individually auxiliary sealing member manufacture and installation difficulty are bigger.
The present invention fundamentally solves the sound chamber sealing problem of metal film loudspeaker, and technique is simpler compared with prior art
Single, cost is greatly reduced, and loadspeaker structure is more compact, manufactures with can be convenient at the edge of electronic equipment, with convenient
The arrangement of other components.
The above is only the specific embodiment of the application, it is noted that for the ordinary skill people of the art
For member, under the premise of not departing from the application principle, several improvements and modifications can also be made, these improvements and modifications are also answered
It is considered as the protection scope of the application.
