Background

At 7 months and 14 late in france, a terrorist attack of "truck-bump crowd" together occurred in the celebration event in france in nissan, resulting in 84 deaths and 18 serious injuries. While france has started to use terrorist attack warning applications in advance, the alarm is delayed by 3 hours due to the network. Afterwards, the french internal administration official speaker represents: after the attack, the 3G and 4G mobile networks and the current Wi-Fi network are crashed, the traffic of the communication network near the nice is too large, the signal tower is not reacted, and the alarm is delayed due to the network crash.

Conventional information transmission platforms mainly acquire information through newspaper magazines, television media, flat billboards and radio programs, however, the acquisition method of the information is often limited by some time and space. With the rapid development of the internet, the acquisition of such information has been able to benefit from the characteristics of the internet and break through the time and space limitations, so that users can easily connect to the internet through personal computers, tablet computers and smart phones to acquire various services provided by the manufacturers, for example: web page information, online chat, and web video, etc.

However, when a terrorist attack or an emergency such as a big earthquake (e.g. 921), the wireless network is broken and blocked due to the simultaneous use of 3G and 4G mobile networks by many people, which further causes communication interruption. Further, the blocking of the information does not allow the circulation of the information, and further serious casualties are caused.

Therefore, how to solve the above problems and deficiencies of the prior art is a path for the inventors of the present invention and related manufacturers to study and improve the present invention.

As apparent from the drawings, the present invention discloses a broadcasting system for transmitting data by using sound waves, for broadcasting the data by using sound, the broadcasting system comprising: a transmitting apparatus 1, a plurality of intermediate devices 2, and a plurality of receiving apparatuses 3.

The sending device 1 is used for providing a message and encrypting the message into an encrypted data. The information may be an internet address or a text message, for example. This information may be preset by the user, for example, for marketing purposes, the user may provide advertising information in advance, or for warning purposes, the user may provide warning information in advance. The transmitting apparatus 1 is configured to transmit the encrypted data. The encrypted data may be encrypted using carry system (such as hexadecimal system), for example, or other techniques that can provide high security of data are also feasible, and the present invention is not limited to this encryption manner as long as the information can be encrypted and encoded as the encryption technique mentioned in the present invention. The transmission method may be, for example, wireless or wired transmission, and is not limited to any method. When the wireless network such as 3G, 4G mobile network is broken down and blocked, the wired method is the better scheme.
