US Patent 10507168 Musical teether

The invention is concerned with a musical teether for infant. It has a body member including one or more regions or projections on which an infant can bite in use for soothing purpose and a musical unit. The body member is configured to receive or otherwise accommodate the musical unit which is removably engageable with the body member. The teether further has means for transmitting vibrational musical signal from the musical unit to the body member for onward transmission to teeth of the infant, then to jaw bones and skull of the infant, and then to ear bones of the infant, such that the infant can, while biting on the teeth, receive vibrational musical signal arisen from direct vibration on the ear bones of the infant.
