| 发明名称 | Sound generator | ||
| 摘要 | A sound generator includes a housing (20), a piezoelectric vibrator (60) including a piezoelectric element (61), at least a portion of the piezoelectric vibrator (60) protruding from the housing (20), and an anchor (10) applying a load to the piezoelectric vibrator (60). A portion or all of the piezoelectric vibrator (60) withdraws into the housing (20) under a force of a predetermined load or greater. While the load from the anchor (10) is being applied to the piezoelectric vibrator (60), the piezoelectric vibrator (60) deforms in response to a sound signal, and deformation of the piezoelectric vibrator (60) vibrates a contact surface contacted by the piezoelectric vibrator (60), causing sound to be emitted from the contact surface. | ||

| 主权项 | 1. A sound generator comprising: a housing; at least one piezoelectric vibrator including a piezoelectric element, at least a portion of the piezoelectric vibrator protruding from the housing; and an anchor applying a load to the piezoelectric vibrator, wherein a portion or all of the piezoelectric vibrator withdraws into the housing under a force of a predetermined load or greater, while the load from the anchor is being applied to the piezoelectric vibrator, the piezoelectric vibrator deforms in response to a sound signal, and deformation of the piezoelectric vibrator vibrates a contact surface contacted by the piezoelectric vibrator, causing sound to be emitted from the contact surface, and the contact surface is a surface of a component that is separate from the sound generator. | ||
