The elastic member is in communication with the inner cavity of the rigid member and is fixedly connected to the flared joint. The side of the elastic piece adjacent to the user's face at least partially abuts the user's nasal bridge area to form an elastic body part, and a support part connected to the elastic body part is provided on the side of the elastic member adjacent to the user's face. The foam member is fixed to the support part and, together with the elastic member, forms a sealing surface for fitting the user's face.

Abstract: A low-noise breathing mask includes an elastic liner, a mask body, and a noise reduction component. The noise reduction component includes a ventilation opening and a muffler. The ventilation opening is provided on the mask body and communicates with a third opening. The muffler is connected to the mask body and covers the ventilation opening. The muffler has a first surface facing the external environment and a second surface opposite to the first surface. The first surface has a first breathable area exposed to the external environment, and the second surface has a second breathable area exposed to the cavity. The muffler also has multiple breathable channels that communicate with the first and the second breathable area, allowing gas in the cavity to be discharged to the external environment through the muffler. The multiple breathable channels in the muffler can render the gas flow smaller and less turbulent.

The nasal area includes a nasal tip area and an alar area. The nasal tip area has at least one thin area for accommodating the user's nasal tip, and the nasal tip area is equipped with a first wing for abutting against the user's columella.

Abstract: A device for delivering gas includes a frame, a gas delivery hose, and a noise reduction component. The gas delivery hose is detachably connectable to the frame. The noise reduction component includes a ventilation port and a muffler. The ventilation port is provided in communication with the cavity of the frame, and the muffler is connected to the frame and covers the ventilation port. The muffler has a first surface having a first breathable area exposed to the external environment, and a second surface having a second breathable area exposed to the cavity. The muffler also has multiple breathable channels connecting the first breathable area and the second breathable area, allowing gas in the cavity to be discharged from the muffler to the external environment. The multiple breathable channels in the muffler can disperse the gas flow, making it less turbulent and reducing the noise generated.

An array of cavities may be formed through a stack of material layers of a memory die, and conductors may be formed at least in part by merging some of the cavities of the array.

Conductors may be formed at least in part by merging two or more cavities of a second subset of the array of cavities using a material removal operation to remove portions of the stack of material layers. Such merging may support conductors being formed with a cross-section that is greater than a cross-section of other features formed using such cavities that are not merged.
