A compact electroacoustic converter to be used in the ear hole which prevents oppressive and inharmonious sensations to the auricle (A) when used and also prevents the deterioriation of the reproduced sound quality.
The speaker arrays in the headphone units use wave front synthesis to reproduce a sound field within a closed curved surface in the vicinity of the auricles.
An earhook (1), for example for a headset, to be worn around the root of the auricle (14) in the postauricular sulcus.
The insert (1, 101) has an open-work structure, is formed flat and its edge contour (3, 103) can be fitted into the auricle (5).
Preferably, the vibrating surfaces (3) of the bone conduction speakers (1) can move forward and backward with respect to the back surfaces of the auricles (20) and can rotate in the horizontal direction.
An upper curved end of the hook (56) hooks over the junction between the user's ear and head so that the transducer (52) touches a lower rear face of the pinna adjacent the concha.
A method of administering an antibiotic to an animal in need thereof, including the step of injecting the antibiotic subcutaneously at the junction of a pinna with the cranium of the animal, is disclosed.
A shell comprising a first part, and a second part, wherein said first part is adapted to fit the contour of the cleft between a pinna and the skull of an individual is provided.
An earpiece for auditory testing.
The earpiece includes a baffle and an enclosure defining a chamber.
The earpiece is sized to fit over the pinna of a patient and to secure and seal to the patient’s head.
The baffle is designed to provide flexibility to ensure a proper fit and seal of the earpiece to the patient and to provide sufficient volume within the chamber to not interfere with the pinna.
