Abstract

There is provided: a lightweight peripheral component for audio equipment having a good balance between a large internal loss and excellent mechanical properties, and having excellent thermal resistance, dimensional stability, and an excellent S/N ratio; and a speaker using the same. The peripheral component for audio equipment of the present invention contains a polyphenylene ether-based resin (A), a polystyrene-based resin (B), and a polyolefin-based resin (C).

Claims (8)

1. A peripheral component for audio equipment comprising: a polyphenylene ether-based resin (A); a polystyrene-based resin (B); and a polyolefin-based resin (C), wherein the polyolefin-based resin comprises at least one selected from the group consisting of polyethylene, polypropylene, and an ethylene/propylene copolymer, and wherein the peripheral component is used for at least one member selected from the group consisting of a horn, a field cover, an equalizer, an equalizer support, and a speaker front mounting plate.

2. A peripheral component for audio equipment according to claim 1 , wherein a weight ratio of the polyphenylene ether-based resin (A) to the polystyrene-based resin (B) (A)/(B) is 90/10 to 70/30.

3. A peripheral component for audio equipment according to claim 1 wherein the polyolefin-based resin (C) is included in an amount of 5 to 20 parts by weight with respect to 100 parts by weight in total of the polyphenylene ether-based resin (A) and the polystyrene-based resin (B).

4. A peripheral component for audio equipment according to claim 1 wherein the polyphenylene ether-based resin (A) and the polystyrene-based resin (B) are alloyed.

5. A peripheral component for audio equipment according to claim 1 wherein the polyphenylene ether-based resin has a number average molecular weight of 5,000 to 1,000,000.

6. A peripheral component for audio equipment according to claim 1 wherein the polystyrene-based resin has a number average molecular weight of 400 to 500,000.

7. A peripheral component for audio equipment according to claim 1 , wherein the polyolefin-based resin has a number average molecular weight of 500 to 100,000.

8. A speaker comprising the peripheral component for audio equipment according to claim 1 .
