This utility model relates to the field of pop-up book technology, specifically to a pop-up book with touch-sensitive sound function, including a cover and a replacement component. The replacement component is detachably installed inside the cover. The cover is composed of a back cover and a
front cover. A sound-generating module is installed on the inner wall of the
front cover, and a connecting latch is installed on the outer edge of the
front cover. A sub-latch that matches the connecting latch is installed on the outer edge of the back cover. The replacement component includes a spine, pages, and pattern printing springs. Multiple pages are installed on the inner side of the spine, and multiple pattern printing springs are installed on the pages. The electromagnets can be released from the individual pattern printing springs by touch buttons, allowing them to achieve a pop-up display effect under the user's control, making it more interactive. The touch buttons will simultaneously trigger the audio stored in the module and play it through the speaker, realizing the combination of pop-up display effect and audio effect.
