Electronic musical instrument and electronic keyboard instrument

An electronic musical instrument comprising:

• a loudspeaker which releases sounds in a first direction in accordance with an instrument playing operation;
• a case which houses the loudspeaker and has a plurality of sound holes which function as bass reflex ports which release acoustics in an acoustic space which is formed around the loudspeaker in a second direction which is opposite to the first direction, in a second region which does not include a first region which faces a rear face of the loudspeaker, wherein the case includes a first case and a second case;
• a board component which is fixed to the case in the second region and forms a bass reflex duct together with an inner wall of the case, wherein the bass reflex duct is arranged such that the acoustics in the acoustic space pass through the bass reflex duct and then are released outside the case through the bass reflex ports;
• and
• an intermediate member which houses the loudspeaker therein, wherein the intermediate member has a fixing hole for mutually fixing the first case, the second case, and the intermediate member.

An electronic keyboard instrument comprising:

• a keyboard;
• a plurality of loudspeakers which releases sounds in a first direction in accordance with an instrument playing operation;
• a case which houses therein at least the plurality of loudspeakers;
• and
• a plurality of sound releasing members which are disposed on an installation face side of the case and between the plurality of loudspeakers and release acoustics in respective acoustic spaces which are formed around the plurality of loudspeakers respectively in a second direction which is opposite to the first direction,
• wherein the plurality of loudspeakers are arranged rearward of the keyboard in a front-rear direction perpendicular to an array direction of keys of the keyboard such that, when viewed from a top-bottom direction perpendicular to the front-rear direction and the array direction, the plurality of loudspeakers and the keyboard do not overlap.
