Although the existing self-service ordering system has the above-mentioned convenience advantages, due to the high installation cost (the high cost of ordering servers and tablets), the store will suffer huge losses once the tablet is stolen or destroyed by consumers.

In addition, consumers often cannot fully understand the actual content of the menu-listed meals. Even if they have read the menu, they still need the helper to explain the meal content and make a manual order, which makes the self-service ordering system of the self-service ordering system. The function is virtually the same.

The main object of the present invention is to provide an electronic menu providing system and an electronic menu providing method for transmitting a electronic menu to a consumer's mobile device using sound waves.

To achieve the above object, the present invention provides an electronic menu providing system using sound wave transmission, comprising an electronic menu providing device and a computer program mounted on a mobile device. The electronic menu providing device includes a sound wave transmitting module, a storage module for storing an electronic menu, a menu sending button, and a control module electrically connected to the sound wave transmitting module, the storage module and the menu sending button. . When detecting that the menu sending button is pressed, the control module reads and encodes the electronic menu as a menu audio signal, and plays the menu audio signal through the sound wave transmitting module. The computer program controls the mobile device to receive and decode the menu audio signal as the electronic menu, and display the electronic menu on the mobile device.

The invention further provides an electronic menu providing method using sound wave transmission, comprising the following steps: a) an electronic menu providing device encodes an electronic menu as a menu audio signal when detecting a menu sending key is pressed; b) a sound wave transmitting module plays the menu audio signal; c) a computer program controls a mobile device to receive and decode the menu audio signal as the electronic menu; and d) displays the electronic menu on the mobile device.
