EAR TIP, EAR TIP COMPONENT, AND EARPHONE
This ear tip includes: a conductive first member ( 10 ) having a cylindrical portion ( 11 ) having a first end and a second end, and a contact portion extending from the first end to the second end side; and an elastic second member ( 20 ) covering the outside of the cylindrical portion, wherein the contact portion is located on the outside of the second member.
1 . An ear tip, comprising:
a conductive first member having a cylindrical portion having a first end and a second end, and a contact portion extending from the first end to the second end side; and
an elastic second member covering the outside of the cylindrical portion, wherein
the contact portion is located on the outside of the second member.
2 . The ear tip according to claim 1 , wherein the first member is formed using a silicon material containing a metallic filler.
3 . The ear tip according to claim 1 , wherein the second member is removably attached to the first member.
4 . The ear tip according to claim 1 , wherein the contact portion includes a first portion that is formed into a dome shape from the first end, and one or more second portions that extend from a predetermined position of the first portion to the second end side.
5 . The ear tip according to claim 4 , wherein a slit is provided between the plurality of second portions.
6 . The ear tip according to claim 1 , wherein the contact portion is provided in plurality, and at least two of the contact portions are electrically insulated.
7 . An ear tip component, comprising:
a cylindrical portion having a first end and a second end; and
a contact portion extending from the first end to the second end side, wherein
the cylindrical portion and the contact portion are formed of a conductive material.
8 . An earphone corresponding to the ear tip according to claim 1 , and comprising:
a first sensor that acquires first biological information;
a second sensor that acquires second biological information at a position different from that of the first sensor; and
a third sensor that acquires third biological information at a position different from those of the first sensor and the second sensor.
9 . The earphone according to claim 8 , wherein
the second sensor comes into contact with a cavum conchae of an upper part of a concha auriculae of a wearer of the earphone, and
the third sensor comes into contact with a cavum conchae of a lower part of a concha auriculae of the wearer.
10 . The earphone according to claim 8 , wherein the second sensor is provided at a tip of a wing protruding from a body of the earphone, and a position of the wing is adjustable with respect to the body of the earphone.
