发明名称 CANAL-TYPE RECEIVER
摘要 In order to achieve the purpose of the present invention of providing a canal-type receiver capable of replaying sound fields spanning front-to-rear and/or top-to-bottom, said receiver is characterized by reflecting sound waves emitted from a sound guiding tube to part of the external auditory canal wall and causing same to reach the eardrum, by having a configuration such that: an earpiece for a canal-type receiver has a cylindrical section that is substantially cylindrical and includes therein the sound guiding tube which emits sound waves radiated from a sound-emission unit inside the receiver to the external auditory canal; and the sound guiding tube is configured such that the directional sound wave radiation axis for the sound waves faces a prescribed position in the wall of the external auditory canal, in a state in which the cylindrical section of the earpiece is attached to a prescribed position in the external auditory canal.
