Abstract | Provided are: a sounding device capable of suppressing a reduction in sound pressure; and a sensor provided with the sounding device. This sounding device (100) is provided with: a plate-like vibrating body (1); a retaining part (2) that retains the vibrating body (1); and a driving part (3) that vibrates the vibrating body (1) in the thickness direction of the vibrating body (1) in response to an electrical signal from outside. The retaining part (2) has a retaining body (4) and a frame (5). The retaining body (4) is made of an elastic material and is in contact with the entire outer periphery of the vibrating body (1) from a direction crossing the thickness direction of the vibrating body (1). The frame (5) holds the retaining body (4).
L'invention concerne : un dispositif sonore capable de supprimer une réduction de la pression sonore ; et un capteur muni du dispositif sonore. Ce dispositif sonore (100) comprend : un corps vibrant en forme de plaque (1) ; une partie de retenue (2) qui retient le corps vibrant (1) ; et une partie d'entraînement (3) qui fait vibrer le corps vibrant (1) dans la direction de l'épaisseur du corps vibrant (1) en réponse à un signal électrique provenant de l'extérieur. La partie de retenue (2) comprend un corps de retenue (4) et un cadre (5). Le corps de retenue (4) est constitué d'un matériau élastique et est en contact avec toute la périphérie extérieure du corps vibrant (1) à partir d'une direction croisant la direction de l'épaisseur du corps vibrant (1). Le cadre (5) maintient le corps de retenue (4).
音圧の低下を抑制可能な発音装置、及びそれを備えた感知器を提供する。発音装置(100)は、板状の振動体(1)と、振動体(1)を保持する保持部(2)と、外部からの電気信号に応じて振動体(1)を厚さ方向に振動させる駆動部(3)と、を備える。保持部(2)は、保持体(4)と、フレーム(5)と、を有する。保持体(4)は、弾性材料からなり、振動体(1)の厚さ方向と交差する方向から振動体(1)の外周の全周に接触する。フレーム(5)は、保持体(4)を保持する。 |
