Abstract

The utility model relates to an inlaid speaker cavity of steel part reaches speaker including this cavity. The utility model provides an inlaid speaker cavity of steel part, including ante -chamber, back cavity, gum, the ante -chamber plays supporting role, installation loudspeaker body, makes for plastic materials, back cavity and ante -chamber be sealed to form complete cavity space, makes for plastic materials, the gum is used for sealed ante -chamber and back cavity, and plays to cushion the damping effect, ante -chamber and back cavity are equipped with the trompil at speaker body mounted position, still include nonrust steel sheet of ante -chamber and the nonrust steel sheet of back cavity, the nonrust steel sheet of ante -chamber is installed at ante -chamber holing position and ante -chamber formation enclosed construction, the nonrust steel sheet of back cavity is installed at back cavity holing position and back cavity formation enclosed construction, the nonrust steel sheet thickness of ante -chamber is lighter than ante -chamber thickness, the nonrust steel sheet thickness of back cavity is lighter than back cavity thickness.

Description

The speaker chamber that a kind of steel part is inlayed and comprise the loud speaker of this cavity
Technical field
The utility model relates to a kind of audio frequency apparatus, especially a kind of speaker chamber.
The utility model relates to a kind of audio frequency apparatus, especially a kind of loud speaker.
Background technology
Current mobile phone, panel computer are miniaturized, and its inside micro speaker chambers body structure is also thereupon thinning, diminish, and most of cavity need go out sound from side, and miniature composite membrane loud speaker gross thickness goes to the limit.
Utility model content
In order to solve the deficiency that prior art exists, the utility model provides the speaker chamber that a kind of thickness is thin, steel part is inlayed.
In order to solve the deficiency that prior art exists, the utility model provides the thin loud speaker of a kind of thickness.
The speaker chamber that a kind of steel part in the utility model is inlayed, comprise ante-chamber, back cavity, gum, described ante-chamber plays a supportive role, installs speaker body, for plastic material is made; Described back cavity and ante-chamber seal and form complete cavity space, for plastic material is made; Described gum is for sealing ante-chamber and back cavity and playing buffer shock-absorbing effect, described ante-chamber and back cavity are provided with perforate in loud speaker body installation site, also comprise ante-chamber stainless steel substrates and back cavity stainless steel substrates, described ante-chamber stainless steel substrates is arranged on ante-chamber position of opening and ante-chamber forms enclosed construction, described back cavity stainless steel substrates is arranged on back cavity position of opening and back cavity forms enclosed construction, described ante-chamber stainless steel substrates thickness is less than ante-chamber thickness, and described back cavity stainless steel substrates thickness is less than back cavity thickness.For the reason such as processing technology, cost, speaker chamber is generally plastics and makes; In order to ensure enough structural strengths, speaker chamber wall thickness generally needs more than 0.6mm, speaker chamber is the bottleneck that loud speaker thickness reduces in loud speaker body installation site, in order to reduce loud speaker thickness further, speaker chamber is replaced with stainless steel substrates at the material of loud speaker body installation site by plastics, greatly can reduce the integral thickness of speaker chamber.
As preferably, the thickness of described ante-chamber stainless steel substrates and back cavity stainless steel substrates is 0.15 ~ 0.25mm.Easy to process, structural strength meets design needs.
As preferably, described ante-chamber stainless steel substrates and back cavity stainless steel substrates are provided with to be convenient to embed the bending in cavity.The bond strength of cavity stainless steel substrates and cavity is high, uses reliable.
A kind of loud speaker, comprise loud speaker body and speaker chamber, described speaker chamber is above-mentioned arbitrary speaker chamber.Loud speaker thickness is low, and structure is reliable.
The beneficial effects of the utility model: speaker chamber is replaced with stainless steel substrates at the material of loud speaker body installation site by plastics, can reduce the integral thickness of speaker chamber greatly, can ensure the structural strength of speaker chamber simultaneously.
Accompanying drawing explanation
Fig. 1 is the loud speaker explosive view that a kind of steel part is inlayed.
Fig. 2 is the loud speaker cutaway view that a kind of steel part is inlayed.
Fig. 3 is existing loud speaker cutaway view.
Mark in figure: 1, ante-chamber stainless steel substrates, 2, ante-chamber, 3, loud speaker body, 4, back cavity, 5, back cavity stainless steel substrates, 6, gum.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but this should be interpreted as that the scope of above-mentioned theme of the present utility model is only limitted to above-described embodiment.
As shown in Figure 3, existing loud speaker comprises ante-chamber 2, back cavity 4, gum 6 and loud speaker body 3, and ante-chamber 2 and back cavity 4 are injection molding, and ante-chamber 2 and back cavity 4 are 0.6mm at loud speaker body 3 installation site wall thickness, loud speaker integral thickness 4.62mm.As shown in Figure 1-2, the loud speaker that a kind of steel part is inlayed, comprises loud speaker body 3, ante-chamber 2, back cavity 4 and gum 6, and described ante-chamber 2 plays a supportive role, installs speaker body, for plastic material is made; Described back cavity 4 seals with ante-chamber 2 and forms complete cavity space, for plastic material is made; Described gum 6 is for sealing ante-chamber 2 and back cavity 4 and playing buffer shock-absorbing effect, described ante-chamber 2 and back cavity 4 are provided with perforate in loud speaker body installation site, also comprise ante-chamber stainless steel substrates 1 and back cavity stainless steel substrates 5, described ante-chamber stainless steel substrates 1 is arranged on ante-chamber position of opening and ante-chamber 2 forms enclosed construction, described back cavity stainless steel substrates 5 is arranged on back cavity position of opening and back cavity 4 forms enclosed construction, described ante-chamber stainless steel substrates thickness is less than ante-chamber thickness, and described back cavity stainless steel substrates thickness is less than back cavity thickness; The thickness of ante-chamber stainless steel substrates 1 and back cavity stainless steel substrates 5 is 0.2mm; Embed in cavity after stainless steel substrates bending, and install location additional on injection mold, steel disc is first placed with injection moulding die cavity before injection moulding, steel disc and glue shell single injection-molded.Speaker chamber is reduced to present 0.2mm at the wall thickness of loud speaker body installation site by original 0.6mm, reduces 0.4mm, and speaker chamber general thickness reduces 0.8mm, and loud speaker thickness is reduced to 3.82mm by 4.62mm.
