An ear piece transducer having a housing incorporating therein an electroacoustic transducer element, the housing being inserted into a concave portion of an auricle, and a ring member having resiliency sufficient to enable it to be attached to the outer peripheral portion of the housing, the ring member being formed so as to be thickest in one radial direction.

A head set speaker and stereo radio playing device exhibits improved harmonics and acoustic fidelity. A resilient and flexible headpiece is sized to fit behind the head of the user. Right and left device enclosures are carried by the ends of the headpiece, and are aerodynamic shaped to minimize wind whistle which may result when the head set is worn while moving rapidly. Right and left behind the ear flanges extend downwardly from a position adjacent to the ends of the headpiece, and aid in the positioning of the right and left ear device enclosures. In a typical application, the device enclosures are positioned immediately forward of the user's ears, allowing ambient sound to be heard. A speaker assembly and a removable battery assembly are carried within each device enclosure. The speakers are oriented within the device enclosures with the speaker magnet directed to, and in contact with, the head of the listener. This achieves two interrelated and significant structural and electronic advantages. First, sound fidelity is improved by using sound reflecting walls and baffles to redirect the sound. And second, antenna functionality is improved by attaching an antenna input to the speaker magnet which is in contact with the listener's skin, and there by connecting the listener's body to the antenna. A charging unit is sized to receive both battery assemblies simultaneously. A circuit card carried within one of the device enclosures contains a stereo radio circuit. On/off, volume up, volume down, scan and reset buttons carried by the device enclosures are in electrical communication with the circuit card, and allow control over radio functionality.

A speaker assembly for securement to the temples of an eyeglass frame, such as sunglasses, is disclosed. In particular the assembly includes an adjustable support which is detachably secured to the temples or fixed permanently thereto. The speaker is supported spaced from the frame and the particularity of its mounting is that it can be pivoted to emitt sound towards the ear of a wearer or fully away from the ear or any intermediate position. This permits the wearer to adjust the direction of the speakers to hear other important sounds that may be directed at him from his back or sideways. Accordingly, if the wearer is listening to the radio in an area where important sounds need to be heard, such as in vehicle traffic, the traffic sound will overpower the earphone speaker sound.

An intra-concha type electroacoustic trasducer has an auxiliary supporter projecting in opposite direction to entrance part of external auditory meatus of the user's ear from a side of the transducer opposite to its sound-radiating side disposed to face the auditory meatus entrance. Reliable mountability of the transducer with respect to auricle of the user's ear is thereby ensured, while an unpleasantness or pain given to the user upon mounting to the auricle can be at least reduced to a remarkable extent.

An intra-concha stabilizer with length adjustable conchal wall hook securely holds an audio transducer or speaker within a wearer's ear. The audio speaker is held within a support integrally included within an outer shell of the stabilizer. Within the outer shell, a conchal wall hook carrier slides along an integrally formed groove within the outside of the outer shell. The conchal wall hook perpendicularly protrudes away from the inside of the outer shell and the conchal wall hook carrier in order to engage the conchal wall of the wearer's ear. When worn, the audio speaker is positioned within the wearer's ear between the tragus and the antitragus. The conchal wall hook is then slidably positioned against the conchal wall of the wearer's ear in order to secure the speaker within the ear.
