Abstract

An electronic device according to the present disclosure includes a speaker. The electronic device includes an inner case that accommodates the speaker, and an outer case that accommodates the inner case, the outer case having therein an opening, or a gap between the outer case and a member adjacent thereto. A predetermined space is formed between the inner case and the outer case. A communicating portion connecting a space inside the inner case and the predetermined space is provided at a position close to the speaker in the inner case. The gap or the opening connects with the predetermined space.

First claim

1 . An electronic device comprising a speaker, comprising:
an inner case that accommodates the speaker; and an outer case that accommodates the inner case, the outer case having therein an opening, or a gap between the outer case and a member adjacent thereto, wherein a predetermined space is formed between the inner case and the outer case, a communicating portion connecting a space inside the inner case and the predetermined space is provided at a position close to the speaker in the inner case, and the gap or the opening connects with the predetermined space.

2 . The electronic device of claim 1 , wherein
the speaker is disposed at a position in a vicinity of the predetermined space in the inner case.

3 . The electronic device of claim 1 , wherein
the predetermined space is formed by recessing a portion of one side portion of the inner case in a direction getting away from the outer case, and wherein the communicating portion is formed in a portion except the certain portion in the one side portion.

4 . The electronic device of claim 1 , wherein
an antenna is disposed in the predetermined space.

5 . The electronic device of claim 1 , wherein
a glass plate is disposed on a main face of the outer case, wherein the speaker is disposed such that a vibration direction of a vibrating plate thereof is perpendicular to a main face of the glass plate, and wherein the communicating portion is formed to guide a sound output from the speaker in a direction in parallel to the main face of the glass plate and to output the sound to the predetermined space.

6 . The electronic device of claim 1 , wherein
the glass plate is disposed on the main face of the outer case, wherein the gap is provided between the outer case and the glass plate.

7 . The electronic apparatus of claim 1 , wherein
the electronic device is a tablet computer.
