dc.description.abstract | Jigsaw stereo speakers can be repeated due to focus on dismantling and good sense of design, it is generally not possible as traditional speakers of strong, stable in structure, but we can not lose the basic needs of the speakers should be, that is, to achieve a certain level of quality.
This paper investigate the effect of three-dimensional jigsaw speaker single speaker audio sound pressure excitation, and produce structural resonance different sound problems and find solutions, because the combination of three-dimensional jigsaw speaker of the assembly through tenon interlocking combination does not use screw, it is not completely closely, so when the single speaker at Bofang various sound effects, changes in the bass tend to make the front and rear plates because the sound pressure and the excitation side to create friction, collisions cause significant noise. In this paper, single speaker for sound pressure generated by the acquired resonance frequency response of the sound pressure transmitted through the microphone, and speakers installed without vibration isolation material and the material than do cross, then find the best vibration isolation material installation position and effectively reduce noise generated due to the resonance structure of annoying noise | en_US |
