  • Patent number: 11032638
    Abstract: A speaker with an integrated air pressure and vibration mitigation system is used to produce high fidelity acoustic and vibratory output. The speaker has a main cabinet a set of ventilation holes, an acoustic driver, a vibration unit, and a dampening unit. The main cabinet is an enclosure that retains the acoustic driver, the vibration unit and the dampening unit in desired orientations. The ventilation holes traverse through the main cabinet and provide exhaust ports for unwanted air pressure force and vibrations to be expelled into the external environment. The acoustic driver is mounted to a first face of the main cabinet. The dampening unit is a filter that is mounted in between the vibration unit and the main housing and prevents the transmission of unwanted vibrations and air pressure between the vibration unit and the acoustic driver. Thus, the acoustic driver can oscillate without hinderance and produce distortion-free audio.
