SPEAKER DEVICE AND ELECTRONIC DEVICE |
| 摘要 |
A speaker device (100) includes a circuit board (10), a piezoelectric element (20), a spacer (30) which is disposed between the piezoelectric element (20) and the circuit board (10), and an air chamber (40). The spacer (30) fixes the piezoelectric element (20) to the circuit board (10) so that an internal space (31) is formed between the piezoelectric element (20) and the circuit board (10). The internal space (31) and the air chamber (40) communicate with each other. For example, the internal space (31) and the air chamber (40) communicate with each other through only an air medium. |

1. A speaker device comprising:
a circuit board;
a piezoelectric element which emits sound waves by vibration;a spacer which is disposed between the piezoelectric element and the circuit board and fixes the piezoelectric element to the circuit board so that an internal space is formed between the piezoelectric element and the circuit board; andan air chamber which is provided separately from the internal space,wherein the internal space and the air chamber communicate with each other. |
