Description

Technology Field

[0001] The present invention relates to a control speaker for emergency broadcasting equipped with a laser pointer, and in particular, in the event of a fire or emergency disaster, while broadcasting warning sounds and evacuation instructions, it projects a laser beam onto the floor of the fire scene through the laser pointer, thereby enabling evacuees to follow the laser beam in situations where visibility is difficult due to smoke. Additionally, a vibrator is installed protruding in the form of a braille block on the floor of the emergency escape route, causing the vibrator to vibrate simultaneously with the projection of the laser beam, allowing evacuees to move in a low posture along the direction of the vibration, thus enabling safe evacuation even in adverse conditions where lights are off or smoke is generated. Background Technology

[0003] Generally, in the event of a fire, the Fire Prevention Act mandates that emergency broadcasts, such as alarm sounds like sirens, be made to users and residents of facilities, including buildings of a certain size.

[0004] This broadcasting system comprises an output selection device that selectively transmits emergency broadcasts to multiple broadcasting zones, speakers installed in each broadcasting zone, an audio amplifier device that amplifies a broadcast signal output from the output selection device and outputs it to the speakers, and a broadcasting control device that controls the output selection device to selectively transmit emergency broadcasts to each broadcasting zone.

[0005] In addition, the conventional broadcasting system is equipped with a fire detection receiving device that receives information about the fire occurrence zone from a fire receiving panel that detects whether a fire has occurred in each of the multiple divided zones.

[0006] Conventional fire alarm devices alerted people to a fire by generating a siren sound when a fire detection element detected a fire or when a person who discovered the fire pressed a switch.

[0007] However, in the event of an emergency disaster such as a fire or earthquake, evacuation broadcasts are conventionally conducted solely through auditory functions using voice signals via speakers. Consequently, when smoke obscures visibility during a fire and lights are turned off, people are prone to confusion and disorientation in the dark, making it difficult to ensure a smooth evacuation of evacuees relying only on simple broadcasts.

[0018] FIG. 1 is a schematic diagram of an emergency broadcast control speaker equipped with a laser pointer according to the present invention. FIG. 2 is a perspective view of the disassembled state of the control speaker of the present invention. FIG. 3 is a perspective view of the assembled state of the control speaker of the present invention. Specific details for implementing the invention

[0019] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0020] FIG. 1 is a schematic configuration diagram of an emergency broadcast control speaker equipped with a laser pointer according to the present invention, FIG. 2 is an exploded perspective view of the control speaker according to the present invention, and FIG. 3 is an assembled perspective view of the control speaker according to the present invention. As illustrated therein, in a plurality of control speakers installed to broadcast a disaster in the event of a fire, the speaker (22) is equipped with a fire detection unit (15) that detects temperature and gas and recognizes when a data value exceeds a preset range; a main control unit (16) that controls the output of an guidance broadcast through a sound output unit (17) and controls the emission of a laser beam in accordance with the detection of the fire detection unit (15); a sound output unit (17) that broadcasts an evacuation guidance broadcast in accordance with the control of the main control unit (16) based on the input of the fire detection unit (15); and in the event of a fire or emergency disaster according to the control signal of the main control unit (16), emits a laser beam toward the floor of the fire site or the emergency exit. It is composed of a laser pointer driving unit (18) and a laser pointer (19) that indicate the exit position as a straight line or an arrow.

[0021] However, when a fire occurs, if the fire is reported verbally through the microphone (11), the main control unit (16) controls the preamplifier (12), audio matrix (13), and amplifier (14) to output to the sound output unit (17).

[0022] Additionally, as shown in FIGS. 2 and 3, the speaker (22) is configured to include a pair of bracket rails (3) installed parallel to each other, a circular bracket ring (4) connected to the bracket rails (3) via a screw (5) based on a bracket (6), a set (2) having a laser emitting part that is tightened by rotating clockwise on the bracket ring (4), and a grille cover (1) that is inserted into a groove of the set (2) and pressed to be connected. When a laser beam is emitted through the laser pointer (19) of the speaker (22), the speaker (22) is configured to include a vibrator driving part (20) and a vibrator (21) that are installed to protrude continuously in the shape of a braille block on the floor toward the emergency exit and are driven to vibrate in conjunction with the laser pointer (19).

[0023] However, the above vibrator drive unit (20) can be configured to cause vibration through solenoid drive or to cause vibration through an eccentric motor.

[0024] The operation of the present invention configured as described above is explained.

[0025] In the present invention, when a person involved reports the occurrence of a fire or disaster through a microphone (11), the occurrence of the fire is output to a sound output unit (17) under the control of a main control unit (16) through a preamplifier (12), an audio matrix (13), and an amplifier (14).

[0026] In addition, even if a person does not manually report the fire through the microphone (11), when a fire occurs, the fire detection unit (15) automatically detects the fire and notifies the main control unit (16), and the main control unit (16) then announces the occurrence of the fire by generating an alarm sound through the sound output unit (17).

[0027] In this way, the occurrence of a fire is notified through the sound output unit (17), and at the same time, the main control unit (16) controls the laser pointer driving unit (18) to generate a laser beam through the laser pointer (19).

[0028] This can help evacuees escape easily by illuminating the escape route with a laser beam, as it is difficult to find an escape route in pitch darkness amidst smoke generated during a fire and when the power is cut off.

[0029] As described above, the speaker (22) configured to include a laser pointer (19) is formed by providing a pair of bracket rails (3) parallel to each other as shown in FIGS. 1 and 2, attaching a circular bracket ring (4) to the bracket rails (3) using a screw (5) based on a bracket (6), tightening a set (2) to the bracket ring (4) by turning it clockwise, and attaching a grille cover (1) by inserting it into a groove of the set (2) and pressing it.

[0030] Here, the method of shining a laser beam onto the floor or escape route through the laser pointer (19) can be set to shine consistently toward one escape route, as well as to shine sequentially while pointing to a movement path so that evacuees can easily exit.

[0031] Meanwhile, a laser beam is emitted through the laser pointer (19) included in the speaker (22) of the present invention to secure an escape route, and at the same time, a vibrator (21) configured to operate in conjunction with the laser pointer (19) is made to vibrate, so that evacuees can move while easily feeling the vibration of the vibrator (21) installed on the floor while in a low crouching position.

[0032] These vibrators (21) are installed so as to protrude continuously in a braille shape from the floor of the fire scene to the escape route, and are installed in conjunction with the laser beam to cause vibration at the same time, so that evacuees can move while following the laser beam and feeling the vibration of the floor, so that in the event of a disaster such as a fire, evacuees can easily and safely escape to the escape route.

[0033] The present invention as described above is not limited to the above embodiments, and it is obvious that a person skilled in the art to which the present invention pertains can apply it usefully through various embodiments. Explanation of the symbols
