Abstract
The utility model discloses a sound box with an adjustable sympathetic chord cavity. The sound box comprises a box body, wherein the top portion of the box body is provided with a cover body, the cover body and the box body are telescopically matched, and a horn is arranged in the cover body. The both body and the cover body of the sound box with the adjustable sympathetic chord cavity are telescopically matched, the size of the sympathetic chord cavity can be adjusted through pressing the cover body, and the sound box with the adjustable sympathetic chord cavity has small volume and convenient carrying, and since the size of the sympathetic chord cavity can be adjusted, and the whole box body and the cover body are made of hard materials, when in use, the sound box can make sound with better acoustic fidelity and audio effects.
Description
Technical field
The utility model relates to the audio amplifier field, relates in particular to a kind of audio amplifier with adjustable resonator.
Background technology
The volume of audio amplifier and effect are somewhat dependent upon the volume of its resonator, and the big more then volume of resonator volume is big more, if the volume of resonator is too small, then can have influence on the volume and the effect of audio amplifier.Along with popularizing of digital products such as MP3, MP4, DVD player, the use of portable loudspeaker box also more and more widely.The user had both required the volume of portable loudspeaker box little, was easy to carry, and required portable loudspeaker box to have better tonequality and audio again, but usually because the resonator of portable loudspeaker box is less, its tonequality and audio are not fully up to expectations.
China's utility model patent 200520067714.0 discloses a kind of portable loudspeaker box that can adjust resonator, comprise the audio amplifier main body and be arranged on audio amplifier interior loud speaker and circuit part, also be provided with flexible resonator on the described audio amplifier main body, should make by soft elastic material by flexible resonator, its axial cross section is continuous corrugated, it is corresponding continuous descending with axial cross section that radial section is, ascending different cross section, an end and audio amplifier main body that the resonator that should stretch is positioned at the main body outside are provided with the clamping apparatus that cooperatively interacts, and this audio amplifier main body is provided with audio input end.The resonator of described portable loudspeaker box is a size variation of adjusting the resonator volume by stretching of soft elastomeric material, as everyone knows, resonator to the influence of volume and tonequality except bulk factor, its material also is a The key factor very, general audio amplifier adopts hard elastomeric material to prepare resonator, and hard elastomeric material can allow sound wave fully be reflected in resonator.Though therefore the described portable loudspeaker box of this patent has the adjustable resonator of volume, solve the too small problem of bringing of portable loudspeaker box resonator to a certain extent, but because its resonator adopts soft elastic material, this can produce harmful effect to tonequality and audio to a certain extent.
The utility model content
For addressing the above problem, main purpose of the present utility model is to provide a kind of audio amplifier with adjustable resonator, can send all reasonable sound of tonequality and audio during use.
For achieving the above object, the utility model adopts following structure:
A kind of audio amplifier with adjustable resonator, have hard casing and hard lid, described casing comprises the sidewall that bottom and bottom periphery are extended up, the casing upper opening, described lid is positioned at the casing top, comprising the sidewall that extends down, is sliding extension formula fit structure between covered body wall and wall box, is provided with loudspeaker in the described lid.
Described lid bottom side wall ends central authorities down have pin thread, the side walls enclose that described casing extends up forms described resonator, described resonator bottom is provided with the box that matches with described pin thread, is provided with between the side wall ends of described lid bottom and the resonator bottom and replaces spring.
Be provided with spring between described box and tank floor.
Described pin thread is a column, is provided with protuberance at the column lower edge.
Described box top is provided with the movable spring slice that matches with described pin thread protuberance.
The corresponding described box of described bottom half position is provided with buckle, and described box bottom is a groove shape, is provided with in the described groove and the described columnar projections that is clasped.
Described bottom half outer surface is provided with the foot pad of projection.
Described wall box is provided with switch.
The utlity model has the audio amplifier of adjustable resonator, be telescopic the cooperation between its casing and lid, can be by pushing of lid being regulated the size of audio amplifier resonator, described audio amplifier volume with adjustable resonator is little, be easy to carry, and, can send all reasonable sound of tonequality and audio during use because its resonator adjustable size, whole box body and lid adopt the hard material preparation.
