<P>PROBLEM TO BE SOLVED: To provide a display device for electrically preventing resonance in a speaker system and vibration propagation to a display part without adding an accessory constituent such as an acoustic reflector, etc., to the speaker system. <P>SOLUTION: A display device includes: a display part 1 having a sound signal output circuit for outputting a sound signal; and a speaker system 2 having a housing 20 joined with the display part 1 and a speaker 21 stored in the housing 20. The display device outputs sound related to the sound signal by outputting the sound signal from the sound signal output circuit to the speaker 21. In the display device, a band stop filter for attenuating the amplitude of the sound signal in a band including the resonance frequency of the speaker system 2 in a joined state with the display part 1 is arranged between the sound signal output circuit and the speaker 21. <P>COPYRIGHT: (C)2012,JPO&INPIT |
