Diving goggles having a detachable camera bracket includes a frame, a pair of lenses, and a mask. The lenses and the mask are mounted to the frame. The camera bracket is detachably mounted on the frame. A lower end of the camera bracket is secured to the frame by means of clipping and hooking, and an upper end of the camera bracket is provided with a retaining seat for mounting a camera. The camera bracket connects the camera with the frame stably. During diving, the diver can take a picture for the underwater scenery conveniently, enhancing the diving entertainment.

The invention relates to a sound reproduction device which comprises a signal source, a power source, an amplifier, and a loudspeaker. The sound reproduction device further comprises an impedance measuring device and an analysis device. The impedance measuring device is connected to loudspeaker leads of the loudspeaker in order to measure impedance values, and the impedance measuring device is connected to the analysis device in order to forward the measurement results. The analysis device is also connected to the signal source and/or to the amplifier in order to adapt a signal fed to the loudspeaker.

An assembly includes a mask, a support piece, a filler piece and a mount piece. The mask has a frame that includes a right lens frame attached to a left lens frame by a bridge that supports a nosepiece, the frame further including a top surface and a connection region that is cut out from the top surface of the frame at the location of the bridge. The support piece is seated inside the connection region. The filler piece is seated inside the connection region and secured inside the connection region by the support piece. The mount piece has a bottom section, and a mount support extending vertically from the bottom section to receive a camera mount. The bottom section is seated inside the connection region and secured inside the connection region by the support piece when the mount piece is secured to the connection region.

An underwater mask includes a buckle with a strap that can be moved and adjusted in the up-down and lateral directions on a wearer's head. The buckle includes a base including a spring with a locking hook, a strap adjuster body turnably attached to the base and including a plurality of engaging teeth configured to sequentially engage with the locking hook according to the turn, a handling member held inside the body and operated from outside the body, and a stopper held by the body. The handling member includes a spring, sliding portion, and a pair of finger pads exposed outside the body by the spring. The stopper includes a sliding contact tapered protrusion that slides sliding against the pair of sliding portions to cause the stopper to swing toward a direction opposite to the strap adjuster body and release the pawl from the engaging teeth of the strap.

The present invention relates to an enhanced electronic diving mask with various image enhancement hardware and software integrated with a diving mask, whereby images may be enhanced to enable a diver to achieve greater visibility and clearer vision while underwater. Notably, the present invention combines techniques that have previously been used in connection with internal patient surgical procedures, so that medical instrument imaging technology used inside the human body may for the first time be used to afford divers clearer vision, more visibility and greater safety.

A water survival mask that seals to the user's face covering the nose and mouth and preventing the unwanted inhalation of water. The mask lets air in through slots located at the bottom of the mask that also allow water to drain out. Once through the slots, water is prevented from entering the mask by a water impermeable barrier that selectively allows for air and not water to be inhaled, which may be a float valve. If water penetrates through the water impermeable barrier it is caught by splash guards and funneled back out of the mask before it can enter the primary airway of the user. The water survival mask works exceptionally well at preventing inhalation of windblown water droplets or wave water when floating in rough waters, thereby preventing pulmonary aspiration and pulmonary edema. It also prevents immediate inhalation of water do to submersion in cold water.
