Abstract
The invention provides a flexible sound box which is mainly used in a portable sound box, or an embedded type sound box system part of a product. The sound box solves problems of sufficient caused by size and volume, and poor toner color caused by small portable sound box volume. The sound box is mainly suitable for a notebook computer or a sound box part of a panel television.
Description
Affiliated technical field
The present invention can stretch audio amplifier: can launch in use, can be shrunk to when closing is that one of 1/3rd to five parts of thickness (deciding according to what of the flexible number of plies) are useful for the audio amplifier on the portable product when launching.Especially can control the flexible thickness of audio amplifier according to the power of volume.
Figure viewed from behind technology
At present, common audio amplifier size, thickness is fixed.Portable audio amplifier requires all smaller, thus the effect of the audio amplifier of thin influence pronunciation, and bass can not well present.The air bag audio amplifier that some is convenient for carrying could normally use dash full air in also needing audio amplifier before using after.
Summary of the invention
Be inconvenient to carry and the not good problem of portable audio amplifier tonequality in order to overcome existing audio amplifier.The present invention is a kind of novel audio amplifier, has not only changed the place of the deficiency of traditional audio amplifier, can also be according to the power of volume and the thickness of Telescopic sound box automatically.
The technical solution adopted in the present invention is: pass through motor driven gear, driven gear rotates when motor rotates, the gear driven below has the circular sleeve of spiral burr and groove, the circular sleeve of last one deck is fixed on the outer bottom layer square sleeve, when rotating under master gear drives, the inner circular sleeve will move up and down under the mutual mechanical function at spiral burr, helical groove, the square sleeve that will drive the outside stretches
The effect that the present invention is useful is: be convenient for carrying when audio amplifier can shrink the saving space obsolete the time, can trail in the time will using, three to five times (according to how much deciding of the flexible number of plies) of the thickness when thickness is contraction.The sound that inner loudspeaker are sent can have enough spaces to empathize, and makes that bass can be good at presenting.

Embodiment
To contraction state, (6) driven by motor (7) travelling gear is done and is rotated counterclockwise as shown in Figure 3 when audio amplifier is in deployed condition, and (7) travelling gear drive (5) master gear is done and turned clockwise.As shown in Figure 6 (24) the outer-hexagonal fixed leg at master gear rear portion and as shown in Figure 9 in (34) interior hexagonal holddown groove interlock mutually on ground floor circular sleeve top, (35) spiral burr of the last layer of interior circular sleeve and (33) helical groove of following one deck mutually interlock up to the layer 6 of interior circular sleeve.Master gear drives six layers of circular sleeve of below and does identical rotation.As Fig. 3, shown in Figure 8 owing to (14) interior layer 6 circular sleeve is fixed on three (30) fixed legs of (13) outer layer 5 square sleeve, under the mutual mechanical function of spiral burr, helical groove, inner circular sleeve will perpendicular to (5) master gear move up and down make in one of circular sleeve overlapping one and overlaping.As shown in Figure 8 outer field ground floor to the all has (a 32) barrier sheet for four layers four jiaos, when outer layer 5 square sleeve moves up and down under the effect of interior layer 6 circular sleeve, each layer square sleeve will drive last layer and do the square sleeve of identical motion top layer up to the outside and touch master gear when being stopped by the barrier sheet of last layer square sleeve.Thereby when making whole audio amplifier back heavy stack make to shrink be thickness when launching 1/3rd to 1/5th (deciding) according to what of the flexible number of plies as shown in Figure 2.
When being in contraction state, arrives by audio amplifier deployed condition, (6) driven by motor (7) travelling gear is done and is turned clockwise as shown in Figure 4, (7) travelling gear drive (5) master gear is done and is rotated counterclockwise, as shown in Figure 6 (24) the outer-hexagonal fixed leg at master gear rear portion and as shown in Figure 9 in (34) interior hexagonal holddown groove interlock mutually on ground floor circular sleeve top, (35) spiral burr of the last layer of interior circular sleeve and (33) helical groove of following one deck mutually interlock up to the layer 6 of interior circular sleeve.Thereby master gear drives six layers of circular sleeve of below and does identical rotation.As Fig. 4, shown in Figure 8 owing to interior (14) layer 6 circular sleeve is fixed on three (30) fixed legs of (13) outer layer 5 square sleeve, under the mutual mechanical function of spiral burr, helical groove, inner circular sleeve will move up and down perpendicular to (5) master gear, as Fig. 9, shown in Figure 3ly after the last layer circular sleeve launches fully, will stop that the circular sleeve that drives lower floor under the effect of annulus moves up and down and launch fully up to interior circular sleeve layer 6 in (36).Same the moving up and down under interior circular sleeve effect of outer square sleeve.Thereby whole audio amplifier can be launched, and the thickness of three to five times (according to how much deciding of the flexible number of plies) when being contraction as shown in Figure 2.
Because the sleeve contact is all compared closely, interior, the corresponding place of outer sleeve all has (31) steam vent can make audio amplifier can not be subjected to atmospheric the influence when launching to shrink, flexible smoothly inner and outer sleeves.
On fixed mount, a fixing hole is arranged all down as shown in Figure 7, (27) top fixing hole is introduced audio signal wire, and (29) end fixing hole is introduced the motor power line.As Fig. 5 when (20) in the audio signal wire of introducing and audio amplifier top cover front just, copper sheet in (21) negative conductor groove welds, (20) in top cover front are just, the copper sheet in the annulus metallic channel of the copper sheet in (21) negative conductor groove and top cover inboard welds by welding hole.The master gear front has four groups (25) just, fixing copper spring leaf welds mutually with the positive and negative electrode of loudspeaker in the metallic channel of (26) negative pole.Close behind the top cover of audio amplifier, (25) on the master gear just, (26) thus inboard annulus copper sheet closely contacts and makes master gear can normally make sound horn when rotating on negative copper spring leaf and the top cover.The motor power line is introduced the direct and motor welding in back from end fixing hole.
Claims (2)
1, the inside and outside structure of audio amplifier is to play the thickness of adjusting audio amplifier with stretching of sleeve.
2, the transmission principle that audio amplifier is flexible is to realize down with the mutual mechanical function of spiral burr, helical groove.
