音響デバイス及び発音装置
Document Type and Number:
Japanese Patent JP7425965
Kind Code:
B2
Abstract:
An acoustic device 3 includes a piezoelectric element and a housing 30. The housing 30 includes a main body portion 31 and a rib portion 35. The main body portion 31 includes a vibrating portion 32 and a plurality of support portions 33. The rib portion 35 is connected to the main body portion 31. The rib portion 35 extends in a third direction between a pair of the support portions 34a and 341) facing each other and separated from each other in the third direction intersecting a second direction, when viewed from the second direction along a vibrating surface. A hollow region V is defined by the vibrating portion 32 and the plurality of support portions 33, The above opening S1 is defined by the rib portion 35 and the main body portion 31 and communicates with the hollow region V. The rib portion 35 covers the middle of the hollow region V when viewed from the second direction.
