Abstract: Provided is an acoustic transducer which is used by being fitted into an ear of a listener, is formed in a compact and lightweight shape, and preferably prevents re-reflection of a sound wave. An acoustic transducer 100 is formed of a film-shaped material having an expanding and contracting action and includes a cylindrical acoustic transducing element 101. The cylindrical acoustic transducing element 101 also functions as a sound guide tube. The acoustic transducing element 101 prevents re-reflection of the sound wave reflected by an eardrum when the sound wave has been generated and prevents localization phenomenon and a feeling of pressure in auditory sense. Also, since the acoustic transducing element 101 is formed in a compact and lightweight shape, the acoustic transducing element 101 generates the sound wave for directly reaching the eardrum or collects the sound at a place near the eardrum without a feeling of foreign materials in a case where a person wears the acoustic transducing element 101 the an ear.

Abstract: Generation of a secondary sound source is inhibited, and a sound quality is improved. Included are a support fixed to a mount base, a speaker unit including a portion to be fixed, and a base casing holding the speaker unit, and the speaker unit is fixed to the support and the base casing with the portion to be fixed being sandwiched between the support and the base casing. With this configuration, the speaker unit will be held stably, a great oscillation from a diaphragm of the speaker unit is less transmitted to the parts other than the diaphragm of the speaker unit, to the member holding the speaker unit, or the like. Generation of a secondary sound source is inhibited, and a sound quality can be improved.
