Description
Technical field
The utility model relates to a kind of audio amplifier, particularly relates to a kind of telescopic miniature loudspeaker box.
Background technology
The essential element that audio amplifier is changed as electroacoustic, its commercially of a great variety, comes point have large-scale audio amplifier and miniature loudspeaker box from volume size.Consider the scope of wave length of sound, audio amplifier is made to obtain good resonating effect, give full play to the usefulness of magnetic speaker, then the physical dimension of audio amplifier need match with wavelength, therefore, the acoustical quality of audio amplifier, the reduction effect of bass zone particularly, often need audio amplifier to have enough large volume, namely will there be larger resonator audio amplifier inside.
Development trend along with portable multimedia apparatus is towards light, thin future development, inevitably when equipment volume become more and more thinner, more and more gentlier time, the size of the audio amplifier that equipment carries and geometry are also correspondingly restricted, thus wherein the tonequality in the bass range of sound must significantly be cut down, from this practical problem, outwards output audio as necessary in portable multimedia apparatus, then have to consider to arrange external subwoofer outside its volume.
In like manner, have the external subwoofer of good tonequality, its size is still bigger than normal, it still has deficiency in portable capability, when this finite volume, disregard the increase loudspeaker of cost or improve other performances such as circuit thus obtain the lifting of certain tonequality, this mode causes production cost significantly to increase.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of reasonable in design for above-mentioned prior art present situation, the telescopic miniature loudspeaker box that volume size energy fast and easy changes, this audio amplifier is when playing use, volume can be made to become large, thus increase resonator volume to promote tonequality, when carrying, can smaller volume be made, thus be convenient for carrying.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of telescopic miniature loudspeaker box, comprise the casing that inside is provided with wiring board and loud speaker, it is characterized in that: described casing comprises the base with inner chamber, be provided with telescopic component in base, the end face of base has the perforation that can pass for telescopic component; Telescopic component is by more piece hollow and lower large little truncated cone sleeve is socketed to form, in two adjacent two joint sleeves, under the internal diameter of upper surface of sleeve be greater than the external diameter of the lower surface at upper sleeve; The bottom of the inwall of other sleeve below the joint sleeve of the top one at least has two pieces of blocks radially extended; Topmost the top of a joint sleeve is covered, be provided with in telescopic component to act on and topmost one save sleeve and make it keep the spring of the trend of moving, and save in sleeve in the top one and between base, be provided with removable lining clamping structure, under the state that jacket casing is received, the lower surface of upper sleeve be just in time resisted against be adjacent under sleeve block on, meanwhile, topmost in a joint sleeve by clamping structure together with base detachable connection.
Above-mentioned clamping structure comprises the annular wall at the middle part be arranged in base, the periphery of annular wall is provided with the cambered outwards fixture block in multiple footpath, the bottom that the inwall of sleeve is saved in described the top one is provided with the draw-in groove that multiple and described fixture block matches, arranging and towards unanimously towards circumferencial direction of each draw-in groove opening.Under the state that jacket casing is received, rotating the top one joint sleeve can make described fixture block screw in relative with base fixing for the top one joint sleeve in respective card slot, rotating backward a joint sleeve topmost then can make fixture block depart from from respective card slot, each sleeve extends upwardly expansion under the action of the spring, this clamping structure has simple, the rationally distributed and easy to operate advantage of structure, only need rotate and topmost can complete locking to this joint sleeve or unblock once joint sleeve during operation.
Above-mentioned base comprises upper casing, lower casing and shelf, described upper casing is fixed on shell lower casing being formed hollow, described shelf is placed in shell, the inner space of shell is separated into upper chamber and lower chambers by this shelf, described wiring board is provided with bottom chamber, sleeve after cover receipts is contained in described upper chamber, and described annular wall is arranged on the shelf.By the separation of shelf, the space that the space making sleeve built-in and wiring board are placed is independent of one another, and layout is more reasonable, and can not mutually interfere between sleeve and wiring board.
Have through hole in the middle part of above-mentioned shelf, be suppressed with resonating membrane between described shelf and lower casing, described loud speaker is fixed on and topmost one saves in sleeve, and has multiple aperture at the top of the top one joint sleeve.The effect that resonating membrane not only plays the compartment is set, also can be improved the effect of tonequality simultaneously.
The sidewall of above-mentioned lower casing is provided with multiple dissimilar port, and each port is all connected with wiring board.
Compared with prior art, the utility model has the advantage of: casing has telescopic component structure, by the flexible loudspeaker box structure constructing a compressible volume of telescopic component, the audio amplifier compression of enough volumes can be had, at telescopic component extended configuration, the inaccessiable acoustical quality of small size audio amplifier can be realized, volume and equivalent volume will be limited to and irrealizable middle bass is accomplished effectively simple and honest, be convenient for carrying after contraction and promote compression strength, this telescopic component is by more piece hollow in addition, and lower large little truncated cone sleeve is socketed to form, the cover time receiving, only need press down a joint sleeve topmost, by the effect of block in lower joint sleeve, upper joint sleeve can drive lower joint sleeve to move down, after each joint sleeve is compressed completely, topmost a joint sleeve is connected with base by clamping structure, thus realize each sleeve lock to fix on confined state, therefore this structural design advantages of simple, sleeve is stretched, only need remove the locking of topmost a joint sleeve and base, respectively save sleeve under the action of the spring and keep extended configuration, the mutual constraint of adjacent sleeve bore simultaneously, guarantee that sleeve can not depart from each other, historical facts or anecdotes shows the simple to operate of audio amplifier change in volume.
