Abstract

Provided is a water-proof sound transmitting member that is less likely to be bonded to a housing at a position other than a normal attachment position. The present invention provides a waterproof sound transmitting member (2) having a multilayer structure. This water-proof sound transmitting member (2) includes: a water-proof sound transmitting membrane (11) to be attached to a housing having a hole that allows sound to pass therethrough; a support layer (12) to be attached to the housing together with the waterproof sound transmitting membrane (11), the support layer (12) allowing sound to pass therethrough; and a housing-side adhesive layer (21) for bonding the waterproof sound transmitting membrane (11) to the housing. The entire peripheral portion of the support layer (12) extends outwardly beyond the housing-side adhesive layer (21).

Dependent claims

A water-proof sound transmitting member having a multilayer structure, comprising:

a water-proof sound transmitting membrane to be attached to a housing having a hole that allows sound to pass therethrough;
a support layer to be attached to the housing together with the water-proof sound transmitting membrane, the support layer allowing sound to pass therethrough;
a housing-side adhesive layer for bonding the water-proof sound transmitting membrane to the housing;
and
a support layer-side adhesive layer, wherein
an entire peripheral portion of the support layer extends outwardly beyond the housing-side adhesive layer,
the support layer has a frame shape, a peripheral edge of which lies beyond a peripheral edge of the water-proof sound transmitting membrane, and is bonded to a peripheral portion of the water-proof sound transmitting membrane by the support layer-side adhesive layer, and
the entire peripheral portion of the support of the support layer also extends outwardly beyond the support layer-side adhesive layer.
