Input-panel-equipped portable speaker device

An input-panel-equipped portable speaker device comprising:

• a cabinet shell body configured to enclose an accommodation chamber which extends forwardly and along a centerline in a longitudinal direction to terminate at a front tubular end, said cabinet shell body having
• left and right mounting walls which extend rearwardly from said front tubular end, and which are spaced apart from each other by said accommodation chamber in a direction transverse to the longitudinal direction, said left and right mounting walls respectively having left and right inner wall surfaces to define said accommodation chamber, said left mounting wall being configured to have an inner peripheral region which defines a fitting opening that extends through said left inner wall surface to communicate with said accommodation chamber, and
• a positioning groove disposed on said right inner wall surface, and extending in the longitudinal direction;
• a speaker driver which has a poleplate portion and a basket frame portion configured to be fittingly mounted in said front tubular end so as to permit said poleplate portion to extend into said accommodation chamber along the centerline;
• an input panel configured to cover said fitting opening, and having an outer major surface on which an input unit is mounted for inputting an audio signal, and an inner major surface which is opposite to said outer major surface in the transverse direction, and which has an outer peripheral region;
• and
• an amplifier circuit board having a right board edge which is configured to be fitted in said positioning groove, and a left board edge which is mounted on said inner major surface such that, when said right board edge is brought to be fitted in said positioning groove, said outer peripheral region is brought to abut against said inner peripheral region through the entire length thereof so as to enable an air-tight engagement therebetween.
