DETAILED DESCRIPTION
[0025] In general, the systems described herein are face masks designed for use by a person for source control of viral spread and intended for use when singing and speaking. In addition to providing efficacy for source control by blocking droplets ejected by the person, it provides a near total level of acoustical transparency and is mechanically designed for less inhibited range of motion of the jaw and articulators as to allow for singing and speaking with improved clarity and freedom.
[0026] In some aspects, the person (wearer) can sing and speak with a clearer and more resonant sound with less loss of overtones, diction, partials and harmonics crucial to the making of choral music. In some aspects, the person can sing with their fuller, clearer, more natural sound than afforded by use of conventional masks.
[0027] In further aspects, the person can breathe more comfortably with full range of motion of the jaw and articulators.
[0028] Turning to the figures,
[0029] The face mask 100 also includes strapping 102 coupled to the face covering portion 101 and configured to secure the face mask 100 to the person. In some embodiments, as illustrated, the strapping 102 is free of engagement with ears of the person when the strapping 102 secures the face mask 100 to the person. In some embodiments, the strapping 102 comprises a neck strap configured to extend around a back of a neck of the person to secure the face mask 100 to the person.
[0030] In some embodiments, the acoustically transparent material is arranged to cover the mouth of the person when the person is wearing the face mask 100. In various embodiments, the acoustically transparent material comprises one or more of an acoustically transparent foam, a DMD acoustic fabric (e.g., polyester), or a nylon material.
[0031] The face mask 100 further includes a jaw portion 103 attached to the face covering portion 101. The jaw portion 103 is arranged to be spaced apart from and underlie a jaw of the person when the person is wearing the face mask 100 to permit the jaw to move. Preferably, the jaw portion 103 is arranged such that it is sufficiently spaced apart (e.g., spaced below) the person's jaw when the person is wearing the face mask 100 that the person's jaw will not contact the jaw portion when the person moves their jaw to make a sound (e.g., to talk, sing, etc.). In other words, the jaw portion 103 is spaced a distance below a person's jaw that is greater than the distance the person can move their jaw from a closed position (e.g., when the mouth is closed) to the lower most position the person can move the jaw too (e.g., when the mouth is fully opened). The jaw portion 103 extends generally rearward (e.g., rearward and downward) from a lower edge 104 of the face covering portion 101. In some embodiments, the lower edge 104 of the face covering portion 101 is arranged to be positioned below the jaw of the person when the person is wearing the face mask 100 and the jaw is closed. In some embodiments, jaw portion 103 has a rear edge shape to correspond to a shape of a neck of the person, the rear edge arranged to be spaced apart from the neck of the person to permit the movement of air into and out of the face mask 100. In some embodiments, the jaw portion 103 comprises an acoustically transparent material, such as the acoustically transparent material described above.
[0032] Preferably, the face covering portion 101 and the jaw portion 103 are sufficiently robust to maintain their shape when at rest. This enables the face mask 100 to still define a face receiving cavity that is sized and shaped to receive the person's face, even when the face mask is not being worn (i.e., when the face mask is at rest on a table top surface). This robustness enables the face covering portion 101 to remain spaced apart from the person's mouth and the jaw portion 103 to remain spaced apart from the person's jaw when the face mask is worn by the person to permit the person's mouth and jaw generally free range of movement to produce sound. For the purposes of this disclosure, the phrase “free range of movement” refers to the ability for a person to move their mouth (e.g., lips) and jaw to produce a sound without having their mouth and chin contact the face mask, specifically, the face covering portion 101 and/or the jaw portion 103. This free range of movement provided by the face mask 100 reduces, if not eliminates, any sensation by the wearer of the face mask of the face mask interfering or inhibiting the wearer from producing a sound (e.g., singing). This makes it more comfortable for the wearer of the face mask 100 to produce the sound.
[0033] In some embodiments, the face mask 100 includes edging 105 (e.g., piping) to secure the acoustically transparent material. In some embodiments, the edging extends generally along an outer perimeter of the face covering portion 101. In some embodiments, the edging extends generally along an outer perimeter of the jaw portion 103. Together, the face covering portion 101 and the jaw portion 103 form the main body of the face mask. The edging 105 extends generally along the outer perimeter of the body. In various embodiments, the edging is affixed at a seam 106 to the body (e.g., the face covering portion 101 and the jaw portion 103). Broadly, the face covering portion 101 and the jaw portion 103 include the edging.
[0034] The face mask 100 may be assembled from multiple pieces or blanks of acoustically transparent material, such as those shown in
[0035] The inside of the face mask 100 is shown in
[0036] In some embodiments, the insert 107 is arranged to cover the mouth of the person when the person is wearing the face mask 100. In some embodiments, the insert 107 comprises an acoustically transparent material configured to permit sound to pass therethrough with minimal barrier, such as the acoustically transparent material described herein.

[0043] In some embodiments, the strapping 302 (e.g., the neck strap) is configured to extend around a back of a neck of the person to secure a face mask 300 to the person. In some embodiment, the strapping 302 is configured to pull the nose cover 311 (and the manually deformable brace 312) against the nose to secure the position of the face mask 300 on the person.
[0044] In some embodiments, the face covering portion 301 includes first and second upper side edges extending generally rearward from the nose cover 311. In some embodiments, the first and second upper side edges of the face covering portion are arranged to extend generally downward along respective cheeks of the person and below respective ears of the person when the person is wearing the face mask. In some embodiments, each of the first and second upper side edges are at least partially arcuate or otherwise configured to conform to the contours of a person's face (e.g., cheeks).
[0045]
[0046] Referring to
[0047] The acoustically transparent material is arranged to cover the mouth of the person when the person is wearing the face mask 500. In various embodiments, the acoustically transparent material comprises one or more of an acoustically transparent foam, a DMD acoustic fabric (e.g., polyester), or a nylon material. Other suitable acoustically transparent materials are within the scope of the present disclosure.
[0048] The face mask 500 also includes strapping 502 coupled to the face covering portion 501 and configured to secure the face mask 500 to the person. In this embodiment, the strapping 502 includes a first or neck strap 502A and a second or head strap 509. The neck strap 502A is configured to extend around a back of a neck of the person to secure the face mask 500 to the person. In the illustrated embodiment, the neck strap 502A includes a strap lock 502B, such as a spring loaded cord lock, to enable a person to selectively adjust the fit (e.g., length) of the neck strap around the person's neck. This makes it easier to ensure a good fit between the person's face and the face mask 500. In the illustrated embodiment, the neck strap 502A is releasably connected to the face covering portion 501 (e.g., at opposite lower, rear corners thereof). The face mask 500 includes a connector 502C, such as a snap-fit connector (e.g., snap-fit or press-fit button), to releasably couple the neck strap 502A to the face covering portion 501. The connector 502C may serve as a breakaway safety feature, that can allow the face mask 500 to be quickly removed from a person's face in the event of an emergency. In another embodiment, the neck strap may be fixed to (e.g., not decoupleable from) the face covering portion 501. In this embodiment, the neck strap may include a breakaway connector, such as a pop barrel connector, to provide the breakaway functionality.
[0049] The head strap 509 is also connected to the face covering portion 501. In the illustrated embodiment, the head strap 509 is connected to the side edges of the face covering portion 501 between (e.g., about the midway point between) the nose cover 511 and the respective lower, rear corners of the face covering portion 501. The head strap 509 may also be removable and connected to the face covering portion with the connector 502C described above. The head strap 509 is configured to extend around a back of a head of the person to adjustably secure the face mask to the person. The head strap 509 is arranged to extend over the ears of the person as the head strap extends around the head of the person. The head strap 509 is configured to pull the nose cover 511 (and the manually deformable brace 512) against the nose to secure the position of the face mask 500 on the person. The head strap 509 and/or the neck strap 502A may be made of generally elastic material and therefor can be elastically stretchable.
[0050] The face mask 500 further includes a jaw portion 503. The jaw portion 503 is attached to the face covering portion 101, at a lower end (e.g., edge margin) thereof. The jaw portion 503 is arranged to be spaced apart from and underlie a jaw of the person when the person is wearing the face mask 500 to permit the jaw to move. Preferably, the jaw portion 503 is arranged such that it is sufficiently spaced apart (e.g., spaced below) the person's jaw when the person is wearing the face mask 500 that the person's jaw will not contact the jaw portion when the person moves their jaw to make a sound (e.g., to talk, sing, etc.). In other words, the jaw portion 503 is spaced a distance below a person's jaw that is greater than the distance the person can move their jaw from a closed position (e.g., when the mouth is closed) to the lower most position the person can move the jaw too (e.g., when the mouth is fully opened). The jaw portion 503 extends generally rearward (e.g., rearward and downward) from a lower end or edge margin of the face covering portion 501. The lower edge margin of the face covering portion 501 is arranged to be positioned below the jaw of the person when the person is wearing the face mask 500 and the jaw is closed. The jaw portion 503 may have a rear edge shape to correspond to a shape of a neck of the person, the rear edge arranged to be spaced apart from the neck of the person. The jaw portion 503 also comprises an acoustically transparent material, such as the acoustically transparent material described above.
[0051] The face covering portion 501 and the jaw portion 503 (e.g., the material, such as the acoustically transparent material) are sufficiently robust to maintain their shape when at rest (see
[0052] The face mask 500 includes edging 505 (e.g., piping) secured to the acoustically transparent material. The edging extends generally along an outer perimeter of the face covering portion 501 and generally along an outer perimeter of the jaw portion 503. Together, the face covering portion 501 and the jaw portion 503 form the main body of the face mask. The edging 505 extends generally along the outer perimeter of the body. The edging is affixed at a seam 506 (
[0053] Referring to
[0054] The face mask 500 includes a lower bridge or neck liner or neck seal 508. The lower bridge 508 fits to a neck of the person and connects the jaw portion 503 to the neck of the person. The lower bridge 508 provides a snug fit to the neck for additional comfort and flexibility. The lower bridge 508 also prevents droplet and large aerosol ejection from between the jaw portion 503 and the neck of the person when the person is wearing the face mask. Preferably, the lower bridge 508 is made of a stretchable fabric (e.g., a 4-way stretchable fabric) to conform to the shape of the neck of the wearer of the face mask 500. For example, the lower bridge 508 can be made from a nylon spandex blend fabric. In the illustrated embodiment, the lower bridge 508 is attached to the jaw portion 503 and the face covering portion 501. The lower bridge 508 is attached to the rear edge (e.g., rear edge margin) of the jaw portion and to lower sections of side edges (e.g., side edge margins) of the face covering portion 501. As a result, the lower bridge 508 is generally folded up (as shown in
[0055] The face covering portion 501 also includes a nose cover 511. The nose cover 511 is configured to cover at least an end of the nose of the person. Specifically, the nose cover 511 is arranged to cover the tip of the wearer's nose. Referring to
[0056] The face covering portion 501 includes first and second upper side edges extending generally rearward and downward from the nose cover 511. The first and second upper side edges of the face covering portion are arranged to extend generally downward along respective cheeks of the person and stop at a position that is generally forward of the person's ears. Each of the first and second upper side edges may be at least partially arcuate or otherwise configured to conform to the contours of a person's face (e.g., cheeks).
[0057] The face mask 500 includes a nose bridge extension or nose bridge seal 513 configured to extend along the bridge of the nose and be positioned between the nose of the person and glasses to prevent the glasses from fogging. The nose bridge extension 513 is sized and shaped to extend over the bridge of the nose and along portions of the wearer's cheeks. The nose bridge extension 513 is connected to the nose cover 511 and extends down along the first and second upper side edges of the face covering portion 501, to prevent the glasses from fogging and provide a more secure fit to different face contours. The nose bridge extension 513 prevents droplet and large aerosol ejection from between the face covering portion 501 and the face (e.g., cheeks and nose) of the person when the person is wearing the face mask. Like the lower bridge 508, the nose bridge extension 508 can also be made of a stretchable material, such as a nylon spandex blend fabric.
