Abstract
At least one exemplary embodiment is directed toward an earphone device with a sealing section for acoustically sealing the meatus of a human ear, which includes an inner ear canal speaker; an inner ear canal microphone; connected to a logic circuit which can include a digital signal processor (DSP), where a sealant operatively attached to an outer section of the earphone acoustically seals the meatus of a human ear canal.
Claims23
An earpiece device comprising:
- an inner microphone;
- an outer microphone;
- an inner speaker, wherein the inner microphone, the outer microphone, and the inner speaker are operatively connected via a support structure;
- and
- a sealant element, wherein sealant element includes at least a first section and a second section, where the first section includes a first material, and the second section includes a second material, where the second material is of a lower durometer than the first material.
A sealant element comprising:
- a first section including a first material;
- and
- a second section including a second material, where the second material has an equal or lower durometer than the first material, where the first section and second section are operatively connected, where the first section and second section when inserted into a channel seals the channel, where the acoustical isolation of the first material is different than the acoustic isolation of the second material.
An inflatable sealant element comprising:
- an inflatable first section;
- and
- a second section, where the first and second section are operatively connected, where the second section is configured to carry fluid to the first section, where the sealant element is configured to be inserted into a channel, where, the first section is designed to absorb acoustic energy when at least partially filled with fluid.
A securing device comprising:
- a first arm having at least one first arm connection pad;
- a second arm having at least one second arm connection pad, where the first arm and second arm are connected at a common rotation point;
- and
- a body encompassing at least a portion of the first arm and the second arm, where the body is configured to seal a channel when the securing device is inserted into a channel.
A method of mitigating the occlusion effect in a shallowly inserted sealing system comprising:
- inserting an expandable section into an ear canal, where the expandable system is shallowly inserted;
- and
- expanding the expandable section to a pressure greater than or equal to a sealing pressure, where the sealing pressure is defined as the pressure where there is at least a 5 dB drop in acoustic energy between a first side of the expandable section to second side of the expandable section.
