Abstract
A circuit board assembly including a circuit board, which has one surface on which circuit elements including a vibration element are mounted, and a cover, which covers at least a portion of the circuit board to reduce a vibration of the circuit board caused by a vibration of the vibration element. The cover includes a cover body spaced apart from the one surface and a partition wall protruding from a surface of the cover body, which faces the circuit board, to cover at least a portion of the vibration element. The partition wall presses the one surface.

A circuit board assembly comprising:
- a circuit board having one surface on top of which a rectangular vibration element is mounted;
- a through-hole which passes through the circuit board from the one surface to a second surface on an opposite side of the one surface to prevent a vibration of the rectangular vibration element from being transmitted to the circuit board, the through-hole comprising a first rectangular through-hole and a second rectangular through-hole spaced apart from the first rectangular through-hole,
- wherein when the circuit board is viewed in a direction perpendicular to the one surface, the through-hole is disposed surrounding at least a portion of a perimeter of the rectangular vibration element, such that the first rectangular through-hole completely surrounds a first short side of the rectangular vibration element and the second rectangular through-hole completely surrounds a second short side of the rectangular vibration element;
- a first partition wall at the first short side and a second partition wall at the second short side, both the first partition wall and the second partition wall being configured to prevent the vibration of the rectangular vibration element from being transmitted to the circuit board;
- and
- a cover connecting the first partition wall and the second partition wall, the cover disposed parallel and adjacent to the rectangular vibration element,
- wherein the first partition wall is disposed adjacent a first side of the first rectangular through-hole opposite a second side adjacent to the first short side and the second partition wall is disposed adjacent a first side of the second rectangular through-hole opposite a second side adjacent to the second short side, and
- wherein the first partition wall and the second partition wall protrude from the one surface.
