A hearing-aid device and a method for transmitting sound through bone conduction are disclosed. The hearing-aid device comprises a piezoelectric-type actuator, housing and connector. The piezoelectric actuator is preferably a circular flextensional-type actuator mounted along its peripheral edge in a specifically designed circular structure of the housing. During operation, the bone-conduction transducer is placed against the mastoid area behind the ear of the patient. When the device is energized with an alternating electrical voltage, it flexes back and forth like a circular membrane sustained along its periphery and thus, vibrates as a consequence of the inverse piezoelectric effect. Due to the specific and unique designs proposed, these vibrations are directly transferred trough the human skin to the bone structure (the skull) and provide a means for the sound to be transmitted for patients with hearing malfunctions. The housing acts as a holder for the actuators, as a pre-stress application platform, and as a mass which tailors the frequency spectrum of the device. The apparatus exhibits a performance with a very flat response in the frequency spectrum 200 Hz to 10 kHz, which is a greater spectrum range than any other prior art devices disclosed for bone-conduction transduction which are typically limited to less than 4 kHz.

The vibrator includes a coil that is directly into two coil halves for generating a dynamic magnetic field and a permanent magnet for generating a static magnetic field. The permanent magnet is radially magnetized and arranged in such a way that the static and dynamic magnetic fields coincide in air gaps formed between the coil and magnet arrangement and the casing, whereby the vibrator provides an axial force.

A spheno-temporal bone conduction communication equipment and/or hearing aid includes a system device, a bone skin conduction oscillator and a carrier device for supporting said abovementioned devices. The carrier device has a structural body, and the structural body allows the supported bone skin conduction oscillator in close contact with the spheno-temporal bone. The bone skin conduction oscillator contains a transducer, and the transducer converts an electrical signal into an acoustic oscillating wave and transmits the acoustic oscillating wave into the inner ear via spheno-temporal bone, or receives an acoustic oscillating wave produced by vibration of the skull when speaking and converts it into an electrical signal. The equipment implements bone conduction transmission of the acoustic oscillating wave via spheno-temporal bone, and can be used in bone conduction speaker, bone conduction microphone, bone conduction multimedia device, bone conduction hearing aid device or bone conduction communication device. The equipment can be used with a nasal bone conduction device, can avoid the defect of much external noise when using air conduction mode and overcome shortcomings of the structure easy to slide and inconvenience to add the component when using commonly used bone conduction.

A bone conduction hearing aid system includes a hearing aid housing with a hearing aid vibrator. A skin interface has an interface connector offset on an outer interface surface and detachably connected to a housing connector. A skin adhesive connects to the skin of a patient user to transmit the sound vibrations through the skin to underlying skull bone for transmission by bone conduction to a hearing organ of the user. When the skin adhesive is pressed against the skin of the user, the skin is initially engaged during an initial engagement period with an initial adhesive force that promotes removal and relocation of the skin interface, and the skin is fully engaged after the initial engagement period with a full adhesive force greater than the initial adhesive force that promotes a fixed secure connection that resists removal of the skin interface.

A telephone with a receiver arousing bone-conduction and air-conduction hearing converts an input electric voice signal into vibration and acoustic signals. Since a conventional telephone has a receiver for only air-conduction hearing, a hearing impaired person cannot use the conventional telephone. In case of a bone-conduction telephone using a bone-conduction vibrator as a receiver, this vibrator is only used for bone-conduction hearing, so that an additional telephone is needed when the ordinary person and the hearing impaired person live in the same place. The telephone with a receiver arousing bone-conduction and air-conduction hearing uses a vibrator of smoothly arousing bone-conduction and air-conduction hearing as a receiver, is capable of hearing a vibration signal through bone-conduction hearing as well as an acoustic signal through air-conduction hearing, makes a hearing-impaired person with conductive hearing loss and an old person who has difficulty in air-conduction hearing use bone-conduction hearing, and makes an ordinary person having a normal sense of hearing use either bone-conduction hearing in a noise environment or air-conduction hearing in a normal environment.
