One of noise issues with LCD TV is buzzing sound from internal parts vibrating and coming in contact with surrounding parts. This vibration is caused by transmitting of vibration from speakers to internal parts. The smaller vibration transmitting to internal parts is, the less chance they come in contact with surrounding parts there is. Therefore, predicting conditions in which less vibration may transmit, during the process of product designing, is effective to counter this buzzing sound issue. However, vibration model of speaker is represented by multi-degree freedom system formula and calculation requires extensive and complicated work. It may also be time consuming to reach an answer. This report explains our finding that vibration of speakers mounted in LCD TV can be represented by limited vibration model.
