LOUDSPEAKER MOUNTING STRUCTURE

PROBLEM TO BE SOLVED: To provide a loudspeaker mounting structure with which an output of a sound with a low-sound frequency region can be enhanced and adverse effects on circuit components by a sound with an inverted phase can be prevented. SOLUTION: The loudspeaker mount structure employs an electronic device case 1, into which a loudspeaker 2 is mounted to made to act as an enclosure, the case 1 is provided with a sound-shielding cap 3, made of a soft material and forming integrally a sound shield section 3b that is installed in the case 1, placed to covers the loudspeaker 2 so as to shield a sound with an inverted phase caused by vibration of sound emitted from a rear side of the loudspeaker 2 in the inside of the case 1 and a duct 3a, that extends in the shape of a duct from the sound shield section 3b, to emit sound with inverted phase to the outside of the case 1. Emitting the sound with the inverted phase via the duct 3a of the sound shield cap 3 can increase the sound with a low-frequency sound region by means of the resonance pipe effect.
