Abstract

An electronic apparatus comprises a housing exposed outside, a piezoelectric vibration element located inside the housing a vibration part having the piezoelectric vibration element in a main surface thereof to be vibrated by the piezoelectric vibration element to generate a sound, and a shock-absorbing part being in contact with the main surface and away from a peripheral edge of the main surface, the piezoelectric vibration element intervening between the shock-absorbing part and the peripheral edge.

Claims

1. An electronic apparatus comprising:

a housing exposed outside;

a piezoelectric vibration element located inside the housing;

a vibration part that includes the piezoelectric vibration element in a main surface thereof and is vibrated by the piezoelectric vibration element to generate a sound; and

a shock-absorbing part that is in contact with the main surface and away from a peripheral edge of the main surface, the piezoelectric vibration element intervening between the shock-absorbing part and the peripheral edge.

2. An electronic apparatus according to claim 1, further comprising:

a proximity detector and a display inside the housing,

wherein the shock-absorbing part is located between the proximity detector and the display.

3. An electronic apparatus according to claim 2,

wherein part of the shock-absorbing part which comes out from between the proximity detector and the display is in contact with the vibration part.

4. An electronic apparatus according to claim 1,

wherein the electronic apparatus further comprises an antenna for a wireless communication on a lower side thereof.

5. An electronic apparatus according to claim 1,

wherein the shock-absorbing part includes a cushion material.

6. An electronic apparatus according to claim 1,

wherein the vibration part comprises a cover panel.

7. An electronic apparatus according to claim 1,

wherein when an application which generates a sound is active, an image which informs of a position where a sound is easy to hear is displayed.
