Embodiment

[0060] As an example, make figure 1 The shown waterproof and sound-permeable component carrier. Specifically, first, double-sided tape A (No. 5636 manufactured by Nitto Denko), a waterproof sound-permeable membrane (NTF610AP manufactured by Nitto Denko), .5605), cushioning material (PORON SR-S-70P manufactured by Rogers Inoue Co., Ltd.), double-sided tape C (No.5603 manufactured by Nitto Denko Co., Ltd.) SS4 series A) sequentially layered, making Figure 4 The laminate shown in (A). Then, a blade is inserted from the double-sided tape A of the produced laminate toward the tab, the double-sided tape A, the waterproof sound-permeable film, the double-sided tape B, the cushioning material, and the double-sided tape C are cut into a predetermined shape, and grooves are formed on the chip, whereby, fabricating Figure 4 The laminate shown in (C). Then, a blade is inserted into the lug of the produced laminate to cut the lug, thereby producing Figure 4 The waterproof sound-pe...

Abstract

Provided is a water-resistant sound transmitting member that is reliably released from a release paper when a protruding section of a tab is pulled. A production method for this water-resistant sound transmitting member (2) includes: a step in which a first layer (71), a preliminary film body (61), a second layer (72), and a preliminary tab body (63) are laminated in said order and a laminate (52a) is prepared; a step in which a blade (90) is inserted from the first layer (71) in the laminate (52a) towards the preliminary tab body (63), the first layer (71), the preliminary film body (61), and the second layer (72) are cut and a first adhesive layer (21), a water-resistant sound transmitting film (11), and a second adhesive layer (22) are formed, and a notch (13n) that connects to the end surfaces of first adhesive layer (21), the water-resistant sound transmitting film (11), and the second adhesive layer (22) is disposed in a surface on the second layer (72) side of the preliminary tab body (63); and a step in which the preliminary tab body (63) is cut and the tab (13) is formed.

Description

technical field [0001] The present invention relates to a waterproof and sound-permeable member in which ear pieces are glued to a waterproof and sound-permeable film for housings of electronic equipment having acoustic devices such as speakers and microphones, and a method for manufacturing the same. Moreover, this invention relates to the waterproof sound-transmitting member carrier which is the form which adhered the release paper to the waterproof sound-transmitting member. Background technique [0002] Electronic devices such as cellular phones, cordless phones, and digital cameras have audio devices housed in their casings. Their housings have openings for allowing sound to pass through. In order to prevent water from entering the inside of the case through the opening, a waterproof sound-permeable membrane that blocks water from passing through the opening while allowing sound to pass through the opening is installed. For example, Patent Document 1 discloses a boot ...
