Recreational bone conduction audio device, system
Patent 8,111,860
A waterproof recreational audio device and method that transmits sound via transcutaneous bone conduction provides high fidelity musical signals to a user. The device can be worn on the head of a user and integrated into various types of headgear. The device is tunable for sound quality and comfort by adjusting and moving the sound transmitting transducers around the head of the user. The present invention uses commercially available transducers to produce sounds in the low, mid and high frequency ranges. A sound source for the musical signal can also be provided as part of the waterproof recreational audio device. Controls enable the user to select volume levels for the high, mid and low frequency ranges, while a volume limiter restricts the mid range to a preset maximum volume level to allow external ambient sounds to be heard via the ear canal and protects the hearing of the user.

A fluidized mixture is issued from a nozzle comprising a fan jet at the outlet, causing the mixture to spread as it is issued. The issued material is collected on a moving collection surface located a distance of between 0.25 and 13 cm from the outlet of the nozzle, prior to the onset of large scale turbulence in the fluid jet. The resulting product has good basis weight uniformity.
