Definitions
- the present application relates generally to headphones for listening to music, voice or other sound, and in particular to combining an in-ear section that delivers sound directly to the ear canal and an over-ear or on-ear section that delivers additional audio vibrotactile stimulation.
- Ear-buds or in-ear monitors can generate the sound waves required in the ear canal to create an auditory percept equivalent to sound experienced from free field loud speakers or from live music or speech. Auditory percepts, however, are only one aspect of the human experience of sound.
- the cutaneous sensory system is also capable of detecting low frequency sounds via the mechanical vibration of cutaneous sensory receptors. This is known as vibrotactile stimulation.
- the skin has two different kinds of touch and two kinds of vibration receptors, also known as mechanoreceptors, relevant to the perception of vibrotactile stimulation: Meissner's corpuscles and Pacinian corpuscles.
- Meissner's corpuscles have a resonant frequency around 20 Hz and the Pacinian corpuscles have a resonance frequency around 200 Hz. Consequently, the cutaneous sensory system is most sensitive to low audio frequencies and sub sonic vibrations.
- both vibrotactile stimulation and acoustic stimulation are important. Furthermore, the experience of sound and music in general can be enhanced by adding vibrotactile stimulation.
- the headphones include an ear-cup with an ear-bud protruding toward the listener's ear-canal.
- the ear-cup substantially covers or surrounds the listener's ear and delivers low-frequency vibrations to the listener's skin exciting fast acting mechanoreceptors.
- the ear-bud is disposed within the listener's ear canal and delivers the full audible range of frequencies.
- the headphones, along with the ear-cup and the ear-bud provide passive noise isolation and can optionally include active noise cancellation.

- Headphones 100 include an ear-cup 110 placed over a listener's ear, a headband 120, and an ear-bud (not pictured) placed within or at the entrance of a listener's ear canal.
- the headphones 100 include various acoustic chambers to deliver audio frequencies and subsonic frequencies to the listener.
- the headphones 100 have more touch-points to the listener then classical headphones: the headband 120, the ear-cup 110, as well as the ear-bud. Due to the many touch points to the listener, the headphones 100 provide a solid, comfortable fit.

- FIG. 3 shows a three quarters view of one of the ear-cups according to one embodiment.
- An ear-cup 300 includes an ear-bud 310.
- the ear- bud can be attached to the ear-cup by an elastic attachment such as a spring or flexible scaffolding.
- the elastic attachment provides sufficient degrees of freedom to enable a universal fit by passively conforming to the listener's ear shape.
- the ear-bud 310 includes a soft ear-bud tip 320 to further increase the listener's comfort.
- the soft ear-bud tip 320 can be made of a soft material filled with fluid such as air, water or a viscous fluid.
- the soft material allows the tip to comfortably shape itself to the listener's ear and entrance to a listener's ear canal.
- the force required to prevent the in-ear section from falling out does not need to be developed by friction on the skin of the listener's ear canal or from a touch point in the ear.
- a gentle force applied to the ear-bud 310 from the ear-cup 300 keeps the ear-bud 310 inside the listener's ear canal or at the entrance of the listener's ear canal, and thus improves the listener's comfort by eliminating friction inside the listener's ear canal.
- the ear-bud 310 delivers clear sound directly to the listener's ear canal.
- FIG. 4 shows an ear-cup associated with headphones, the ear-cup placed proximate to a listener's ear, according to one embodiment.
- the ear-cup 400 includes a vibrotactile speaker 420, and an ear-bud 430.
- the ear-bud 430 disposed within or at the entrance of a listener's ear canal, includes an auditory speaker 410 and a soft ear-bud tip 440 that occludes the listener's ear canal from external audio, such as audio outside the ear-cup and audio outside the ear-bud.
- the auditory speaker 410 can be a balanced armature driver or a dynamic driver.
- the ear-cup 400 is disposed to prevent a substantial portion of ambient sound from reaching the listener's ear.
- the ear-cup 400 can completely surround the listener's ear by pressing against the listener's skull (circumaural), can partially press against the listener's skull and the listener's ear, or can solely press against the listener's ear (supraural).
- the vibrotactile speaker 420 can be a dynamic loud speaker.
- the vibrotactile speaker 420 can deliver sub sonic vibrations and/or low-frequency audio to the listener's skull and/or the listener's ear. Because the listener's ear canal is occluded by the ear-bud 430, the vibrotactile speaker 420 can be driven to a louder sound pressure level than an equivalent standard headphone. Consequently, the louder sound pressure provides enhanced vibrotactile stimulation.
- Spring 450 provides elastic attachment of the ear-bud 430 to the ear-cup 400, thus increasing the listener's comfort, as discussed herein.
- the vibrotactile speaker 420 can also be used to provide Active Noise Cancellation cancelling out ambient noise.
- the ear-cup 400 and the ear-bud 430 provide additional methods for passive acoustic isolation.
- the soft ear-bud tip 440 placed within or at the entrance of the listener's ear canal, and the ear-cup 400, provide a double layer of isolation greatly reducing the amount of outside noise that can be heard by the listener while wearing the headphones. Additionally, the double layer of isolation greatly reduces the amount of the sound that leaks out of the headphones into the outside environment.
- the double layer of isolation provides excellent acoustic isolation for others, allowing the listener to enjoy sound without disturbing those around the listener.
- the double layer of acoustic isolation improves characterization of the listener's hearing profile.
- the acoustic isolation allows for a reduction in the amount of outside noise that enters the ear canal. Consequently, the acoustic isolation allows for faster and more accurate measurement of the listener's hearing profile as described in U.S. patent application 15/154,694, filed May 13, 2016, entitled PERSONALIZATION OF AUDITORY STIMULUS, and incorporated herein by reference.

- the second stage of ANC is performed using a microphone on the outside of the second acoustic chamber 540, such as microphone 590, the second speaker 530, and microphone 580.
- the isolation of the listener's ear-canal provided by the ear-bud tip 555 ensures that the stimulation of the first speaker 510 affects minimally or not at all the stimulation delivered through the ear-bud 550.
