Abstract
Description
[0001] A SOLID MEDIA SOUND TRANSMISSION SPEAKER
[0002] Technical Field
[0003] The present invention relates to a solid media sound transmission speaker designed for use in earthquake and cave-in environments.
[0004] State of the Art
[0005] An earthquake is a seismic event that occurs as a result of the sudden movement of the rocks in the earth's crust with released energy. With the spread of this energy, vibrations occur on the ground surface.
[0006] Earthquakes may cause damages on the ground surface, tsunamis, earthflows and landslides, fires and as a result, they may affect societies socially and economically, cause infrastructure damage and cause casualties. In particular, the first few hours after the earthquake are a critical time for rescue operations and it is vital that urgent measures are taken. Steps to be taken in the first hours can increase the effectiveness of rescue teams and minimize the damage caused by the disaster. The most urgent need is to save people who are trapped under the rubble or injured.
[0007] The methods used to reach the earthquake victims under the rubble are complex and careful procedures adopted by professional rescue teams. One of the methods currently used is acoustic and thermal sensing devices. These devices exhibit acoustic and thermal detection to detect sounds and hot spots under the rubble. However, since these devices with acoustic features transmit the sound from the air environment, the rescuers are often hesitant about whether the sound actually reaches victims or not. Because the amount of air in the collapsed environment is much less than the environment, the environment that will carry the sound will be affected by this situation. Since sound propagates in waves in an environment, it needs the presence of air, and it is known that the amount of air directly contributes to the transmission of sound. The disaster coordination system after the earthquake is explained in the utility model application numbered TR202020425. It is a disaster coordination system to be used for coordinating first aid services and search and rescue activities after earthquakes and similar natural disasters, and characterized in that it comprises cameras to determine the number of people in the buildings to be integrated into the system, sensors to determine the durability of the buildings integrated into the system, and a data collection center to record and process the number of people and building durability information.
[0008] The equipment used in the system described in the above-mentioned utility model application such as cameras, sensors and data collection center are very expensive, and these systems are also difficult to use. In particular, technical problems of cameras and sensors can cause incorrect readings and system failures. This can lead to considerable distress, especially in times of such disasters.
[0009] As a result, a new technology is needed that can overcome the above-mentioned disadvantages.
[0010] Definition of the Invention
[0011] The main advantage of our system is to eliminate the difficulties in sound transmission in environments where the air is not continuous, especially in environments where the air flow is minimal, and to ensure that the sound from the rescuer reaches the earthquake victim more effectively.
[0012] The basic logic of our system is based on the principle of sound propagation in solid medias. In particular, the system in our invention converts the incoming electrical current into a vibration wave and transmits it to the metal part, and the metal part transmits the sound vibrations to the earthquake victim through the walls of the building that collapsed after the earthquake. In this way, there is no concern about whether the sound reaches the earthquake victim or not. Thanks to the easy fixing of the components forming the invention, it is easy to install, and the costs are low due to the short installation time. The invention also has a robust structure.

[0021] Detailed Description of the Invention
[0022] The parts forming the invention are basically the coil (1), magnet (2), and metal part (3).
[0023] The working principle of the system according to the invention is as follows: the sound waves to be created by the rescuer personnel in the event of an earthquake are converted into electrical current by means of equipment such as a microphone. This electrical current will be transmitted through the cable environment and can also be produced and transmitted wirelessly as an electromagnetic signal through any equipment. After the incoming electrical current, the coil (1) and magnet (2) act and produce vibration, which is transmitted to the metal part (3). The metal part (3) transmits these sound vibrations to the rubble piles formed during the earthquake, allowing the sound to propagate in a solid media. Therefore, since sound waves will be used more intensively in solid medias, a more effective solution will be produced compared to the air environment.
