Abstract

The present invention comprises: a main body (1) which is sealed so as to be waterproof and has buoyancy; and a holder (4) which holds the main body (1) and opens an internal circuit of the main body (1). A speaker (2) is disposed on one end side of the main body (1), and on the occasion of shifting the center of gravity of the main body (1) and the main body (1) floating to the water surface, the speaker (2) protrudes above the water surface. The holder (4) holds the main body (1) and indirectly or proximately opens the internal circuit of the main body (1) without harming the waterproof sealing of the main body (1). During usage, the main body (1) is pulled and released from the holder (4), thereby closing the internal circuit of the main body (1) and activating the speaker (2). The pulled and released main body (1) floats up to the water surface, and sound is emitted from the speaker (2) protruding above the water surface.

Description

Detachable start-up floating waterproof buzzer

The present invention relates to an alarm buzzer that can be used even from underwater.

A battery-powered or dry-cell-powered floating buzzer using seawater has been devised, but it is difficult to use in water because it is configured to be dropped from the water onto the surface of the water (see Patent Document 1). When used from underwater, a type that can be activated by releasing the buzzer is effective. Some buzzers can be activated by pulling them out from the switch pin, and waterproofness is taken into consideration (see Patent Document 2).

As described in paragraph 0034 of the document, the one shown in Patent Document 2 is considered to be waterproof for daily life, and is difficult to use in water. For example, since the switch pin directly opens and closes the circuit contact of the switch hole, the electrode of the switch hole is exposed, and even if a sealing member is applied to the joint between the switch pin and the switch hole, the switch pin is a movable member. As long as there is a risk of flooding. In addition, when stopping the buzzer that was started by mistake, a flooded switch hole or a wet switch pin may cause a problem. The resonance part of the speaker and the labyrinth structure of the cap to prevent flooding are also structures in which water stays once flooded. Adhesives and rubber materials that seal speakers may peel off due to deterioration or vibration caused by flooding. When the buzzer is used underwater, it is always exposed to water pressure, so stronger waterproofness is required. Labyrinth structure Seal member Seal member Seal member

The purpose of this application is to provide a buzzer with strong waterproofness that can withstand underwater carrying and use.

The waterproof buzzer of the present invention ensures the waterproof and airtightness of the main body (1) in view of the above problems. It is recommended that the outer shell of the main body (1) is similar to a cylinder or a sphere, which is advantageous for water pressure resistance, and is integrally molded to be seamless. The main body (1) opening for assembling internal parts and replacing batteries has a screw structure in the opening itself, and a waterproof ring (1b) is sandwiched between them to fasten a lid screw (1a). The main body (1) opening for the speaker (2) has a screw structure on the opening itself, and a speaker (2) as a lid and a waterproof ring (1b) are sandwiched between them to form a resonance cap (2a). Fasten the screw part of the protective cap (2c). The opening for the speaker (2) can also be used as an opening for assembly or battery replacement, and the opening of the main body (1) can be made in one place. When the resonance cap (2a) is used for the resonance of the speaker (2), the sound emitting port is covered with a vibration film (2b) to make it waterproof. The vibrating film (2b) vibrates and emits sound by bringing a film such as rubber or plastic into close contact with the sound emitting port and forming the resonance cap (2a) into a drum structure. Alternatively, a drain port (2d) is opened on the bottom surface of the resonance cap (2a). The bottom surface should be closer to the main body (1) at the same level as the speaker (2) or higher. When the drain port (2d) is opened in the resonance cap (2a), the resonance effect, that is, the sound increasing pressure effect is reduced, but the peripheral end of the resonance cap (2a) is extended toward the main body (1) to extend the main body (1). ) Floats on the surface of the water, so that the edge of the periphery is submerged in the water, the resonance sound wave is reflected back on the surface of the water and supplements the resonance effect.

By providing a holder (4) for opening the internal circuit, arranging the speaker (2) on one end side of the main body (1), and arranging, for example, a battery (3a) or an element substrate (3b) on the other end side. , The center of gravity of the main body (1) is moved so that the speaker (2) protrudes above the water surface when the main body (1) floats on the water surface, and the holder (4) is, for example, a C-shaped plate. A convex part is provided on the middle abdomen, and the main body (1) is held by holding the main body (1), and the convex part is inserted into the opening of the main body (1) which is covered with an elastic material and is waterproof. , Press the push-off switch (3c) inside the main body (1) through the covering part (1c) to keep the circuit open, or make the convex part with magnetic force or conductivity into the main body (1). ), Hold the main body (1), and let the sensor switch (3d) inside the main body (1) sense the magnetic force and conductivity through the wall to open the circuit. Or, with a plate having magnetic force, pull the soft magnetic material part (1d) on the main body (1) side to hold the main body (1), and at the same time, hold the main body (1) and the sensor switch (3d) inside the main body (1). ), The magnetic force is sensed through the wall to keep the circuit open, that is, the main body (1) is held and the main body (1) is indirectly sealed without damaging the waterproof seal. By keeping the internal circuit of the main body (1) open, either in water or in water, by pulling out the main body (1) from the holder (4). , The internal circuit of the main body (1) is closed to activate the speaker (2), and the released main body (1) floats on the surface of the water or rises to the surface of the water, and the speaker protrudes above the surface of the water. Make the sound emitted from (2).

The mounting portion (5) integrated with the holder (4) is mounted on the water entrant himself or his surroundings, or integrated with the water entrant's mounting equipment such as goggles, an underwater mask, and a swimming cap. When the drowning person pulls out the main body (1) from the attached holder (4), the speaker (2) is activated and the pulled out main body (1) is on the water surface. Float on or ascend to the surface of the water so that sound is emitted from the speaker (2) protruding above the surface of the water.

The mounting portion (5) integrated with the holder (4) is of a winding type, one end thereof is integrated with the holder (4), and the other end is fixed to the main body (1) during drowning. By pulling the main body (1) from the mounted holder (4), or by pulling the mounting part (5) strongly and pulling the holder (4) from the main body (1). The speaker (2) is activated so that the main body (1) with the mounting portion (5) floats on or rises to the surface of the water so that sound is emitted from the speaker (2) protruding above the surface of the water.

The waterproof buzzer of the present invention can be provided with strong waterproofness that can be carried and used underwater. It can also be attached to the person entering the water or surrounding objects and used for water accidents such as drowning.
