The invention concerns a gong (100) for a clock strike device. The gong (100) comprises a multilayer main body (10), which includes a central layer (13) made of metallic material and an upper layer (14) and a lower layer (15) made of piezoelectric material, wherein the upper layer (14) and the lower layer (15) have a respective outer coating layer (16, 17) made of metallic material. The gong (100) further comprises a metal bridge (30), which can be operated between a first operating position of absence of contact with the multilayer main body (10), whereby the upper (14) and lower (15) layers are in an open circuit condition, and a second operating position of contact with the multilayer main body (10), whereby the upper (14) and lower (15) layers are in a short circuit condition. The invention also concerns a clock (1) comprising a gong (100) as defined above.

Abstract
The invention concerns a gong (100) for a clock strike device. The gong (100) comprises a multilayer main body (10), which includes a central layer (13) made of metallic material and an upper layer (14) and a lower layer (15) made of piezoelectric material, wherein the upper layer (14) and the lower layer (15) have a respective outer coating layer (16, 17) made of metallic material. The gong (100) further comprises a metal bridge (30), which can be operated between a first operating position of absence of contact with the multilayer main body (10), whereby the upper (14) and lower (15) layers are in an open circuit condition, and a second operating position of contact with the multilayer main body (10), whereby the upper (14) and lower (15) layers are in a short circuit condition. The invention also concerns a clock (1) comprising a gong (100) as defined above.File | Dimensione | Formato | |
