Patent ID: 8385569

Claim:
An acoustic transducer unit comprising: a first member having a body defining a recess; a second member covering the recess of the first member to form a housing; an acoustic transducer accommodated in an internal space of the housing; an acoustic path communicating between the internal space and an external space of the housing; an electromagnetic-shielding member embedded within a wall of the body and having conductivity; and a terminal member having an internal terminal portion that extends in the internal space of the housing and is electrically connected to the acoustic transducer, an external terminal portion that extends to the external space, and a connecting portion connecting the internal terminal portion and the external terminal portion, wherein the second member has conductivity and is electrically connected to the electromagnetic-shielding member, wherein the second member has: a first opening communicating with the external space, the first opening being provided in a first surface of the second member distal from the first member; a second opening communicating with the internal space, the second opening being provided in a second surface of the second member proximal to the first member; and an acoustic path communicating between the first and second openings, the acoustic path being provided inside the second member, and wherein the first and second openings are distant from each other when viewed in a direction normal to the first and second surfaces of the second member.
