Claims

[Scope of utility model registration request]

A headphone comprising a speaker section connected to the audio equipment side by a speaker cord having a headphone plug at one end, and a variable resistor for adjusting the volume for adjusting the signal level from the audio equipment side, the variable resistor The resistor is placed on the substrate on which the speaker unit is placed, and the resistor element is formed along the outer periphery of the speaker unit.
A tongue-like contact portion that is fitted around the outer periphery of the unit, elastically contacts the resistor element, and changes the resistance value of the resistor element interposed in the signal line at the contact position, and a speaker portion. 1. A headphone comprising a slider having an operation part that projects outward from a housing, and wherein the slider is rotated by the operation part about a speaker unit.
