Abstract
The utility model discloses an inverted tube structure applied to a mobile phone. The inverted tube structure comprises an inverted tube, wherein an upper layer of sound channel is arranged on the upper surface of the inverted tube; a lower layer of sound channel is arranged on the lower surface of the inverted tube; a through hole for communicating the upper layer of sound channel with the lower layer of sound channel is formed in the inverted tube; a PET(polyethylene terephthalate) sheet is stuck to the upper surface of the inverted tube; and the lower surface of the inverted tube is bonded with an adhesive sheet. By the inverted tube structure, the length of the inverted tube is prolonged under the condition of the same size, and the sound quality effect is effectively improved. The inverted tube structure is applied to the mobile phone, the volume of the rear cavity of the mobile phone is effectively saved, and the thinner and smaller mobile phone can be made.
Description
Technical field
The utility model relates to a kind of phase-reversing tube, specifically a kind of phase-reversing tube structure that is mainly used on electron number such as the mobile phone friend product.
Background technology
The application of sound chamber on mobile phone can effectively promote acoustical quality behind the inverted phase type.Sound chamber behind the inverted phase type on the mobile phone generally all is to realize through phase-reversing tube is installed at present.Present phase-reversing tube is generally single layer structure, because the length of sound channel generally needs more than the 30mm, causes the phase-reversing tube volume ratio bigger; Taken more space, back sound chamber; Influenced acoustical quality,, made thinner littler that mobile phone is difficult to do simultaneously because phase-reversing tube is bigger.
Summary of the invention
The technical problem that the utility model will solve provides a kind of phase-reversing tube structure that is mainly used on the mobile phone, effectively saves the back sound cavity volume of mobile phone, promotes tonequality.
In order to solve the problems of the technologies described above, the utility model is taked following technical scheme:
A kind of phase-reversing tube structure; Comprise phase-reversing tube; The upper surface of said phase-reversing tube is provided with the upper strata sound channel, and the lower surface of phase-reversing tube is provided with lower floor's sound channel, and phase-reversing tube is provided with the through hole that is communicated with upper strata sound channel and lower floor's sound channel; The upper surface of the phase-reversing tube PET sheet that has been sticked, the lower surface and the film of phase-reversing tube are bonding.
As the improvement to technique scheme, said film is a double faced adhesive tape.
The utility model is mainly used on the mobile phone, has extended below the length of phase-reversing tube in the condition of equal volume, effectively promotes acoustical quality, has also saved back sound cavity volume, and the more book that mobile phone is done is littler.
Description of drawings
Accompanying drawing 1 is the decomposing state structural representation of the utility model;
Accompanying drawing 2 is the cross-sectional view of the utility model.
Embodiment
For the ease of those skilled in the art's understanding, the utility model is done further to describe below in conjunction with accompanying drawing.
Like accompanying drawing 1, shown in 2; A kind of phase-reversing tube structure comprises phase-reversing tube 2, and the upper surface of said phase-reversing tube 2 is provided with upper strata sound channel 4; The lower surface of phase-reversing tube 2 is provided with lower floor's sound channel 5; Phase-reversing tube 2 is provided with the through hole that is communicated with upper strata sound channel 4 and lower floor's sound channel 5, the upper surface of the phase-reversing tube 2 PET sheet 3 that has been sticked, and the lower surface of phase-reversing tube 2 and film 1 are bonding.This film 1 is a double faced adhesive tape.
The utility model is mainly used on the mobile phone, because two-layer sound channel up and down is set on phase-reversing tube, under the condition of equal volume, prolongs the length of phase-reversing tube sound channel, has promoted acoustical quality greatly.When being assembled on the mobile phone, the double faced adhesive tape and the handset shell of phase-reversing tube lower surface fix.Effectively saved the back sound cavity space of mobile phone, the more book that mobile phone can be done is littler.
