Abstract

An electronic device includes a chassis which has mutually partitioned first chamber, second chamber and third chamber, an electronic substrate which is housed in the first chamber, loudspeaker modules which are housed in the second chamber and the microphones which are housed in the third chamber.

First claim

The invention claimed is:

1. An electronic device comprising:
a chassis which has mutually partitioned chambers, including a first chamber, a second chamber and a third chamber;
an electronic substrate housed in the first chamber;
a loudspeaker housed in the second chamber; and
a microphone housed in the third chamber, wherein:
the chassis includes a first chassis in which the first chamber and the second chamber are disposed, and a second chassis attached to an upper surface of the first chassis and in which the third chamber is disposed,
an inner space of the first chassis is partitioned into two upper and lower stages with a frame member, and thereby the second chamber is above the first chamber, and
the loudspeaker is on an upper surface of the frame member.

2. The electronic device according to claim 1 , further comprising:
a cooling module housed in the first chamber and disposed above the electronic substrate, wherein:
the cooling module has a fan which sucks air from outside of the first chamber and exhausts the air to the outside of the first chamber, and has a fin disposed in an air flow path which is created by the fan and absorbs heat generated from a heating element mounted on the electronic substrate.

3. The electronic device according to claim 2 , wherein:
the first chassis has a disc-shaped bottom section and a peripheral surface section disposed on the bottom section, and has a conical outer peripheral surface having an outer diameter thereof that is gradually reduced in an upward direction, and
the second chassis is in a disc shape and is attached to an upper surface of the peripheral surface section.

4. The electronic device according to claim 3 , wherein:
an input operation section is in the second chassis.

5. The electronic device according to claim 3 , wherein:
the frame member has a protruding part which extends along a front-rear direction of the first chassis and is expanded upward, and has one pair of plane parts which is on both sides of the protruding part in a right-left direction which is orthogonal to a direction that the protruding part extends,
the loudspeaker is on each of one pair of the plane parts and
the cooling module is at least partially housed in a space which is formed on a lower surface side of the protruding part and makes air flow along the front-rear direction.

6. The electronic device according to claim 5 , wherein:
a suction port, through which air is sucked into the first chamber, is on one side of the bottom section in the front-rear direction, and an exhaust port, through which the air is exhausted from the first chamber, is on the other side of the bottom section in the front-rear direction.

7. The electronic device according to claim 5 , wherein:
a connection terminal to which a cable, which electrically connects the electronic substrate with an external device is to be connected, is on the bottom section and
the connection terminal is at a position where the connection terminal overlaps the air flow path created by the fan of the cooling module.

8. The electronic device according to claim 5 , wherein:
the loudspeaker on the plane part, which is located on left of the protruding part, faces an inner surface of the peripheral surface section with a gap being interposed therebetween by being arranged to direct toward diagonally upper left in the right-left direction,
the loudspeaker on the plane part which is located on right of the protruding part, faces the inner surface of the peripheral surface section with a gap being interposed therebetween by being arranged to direct toward diagonally upper right in the right-left direction, and
holes are in the peripheral surface section at least at positions where the holes face the loudspeakers.
