PROBLEM TO BE SOLVED: To provide an earphone which prevents a carbon nanotube film of a speaker from being damaged easily, achieves excellent stereo effect, has a simple structure, facilitates manufacturing, downsizing, and industrialization, and facilitates replacement of a sound wave generator in repair.SOLUTION: An earphone includes an outer case 110, and at least one speaker 100'. The outer case has a storage space, and each speaker includes: a first substrate; a sound wave generator; at least one first electrode; and at least one second electrode. The first electrode includes a first surface and a second surface which face each other. The sound wave generator is installed on the first surface of the first substrate. The at least one first electrode and the at least one second electrode are installed on the first surface of the first substrate, with some interval apart from each other and are electrically connected with the sound wave generator. |
