Abstract
A flexible substrate transducer assembly integrates a transducer or transducer system with built-in signal processing capability, and a flexible substrate. The flexible substrate provides connectivity between the transducer system and electronic equipment which house the transducer assembly. This assembly is adapted for use in compact equipment such as mobile phones and hearing instruments that benefit from the small outer dimensions achievable for the assembly.
Claims26
A flexible substrate transducer assembly, comprising:
- a flexible elongate member having an upper and a lower surface and comprising at least two conductors that each has an exposed part at a first end of the member and a contact pad at a second end of the member,
- a transducer system adapted to generate or receive a transducer signal on two or more signal terminals and to convey the transducer signal from the two or more signal terminals to the respective contact pads, the transducer system being attached to the upper surface at the second end of the flexible elongate member,
- a lid attached to the upper surface of the flexible elongate member and covering and shielding the transducer system and a supporting area of the flexible elongate member from an external environment,
- wherein the supporting area of the flexible elongate member comprises one or several holes extending through the flexible elongate member so as to provide a first passage to the external environment between the lower surface of the member and the transducer system covered by the lid.
