Technical Field

[0001] This utility model relates to the field of megaphone technology, specifically a megaphone for teachers. Background Technology

[0002] A megaphone is an electronic device used to amplify audio signals, thereby increasing the volume and range of sound. It is suitable for various occasions such as speeches, meetings, teaching, and musical performances. Among them, megaphones for teachers are an important tool for teachers to deliver lectures, enabling them to clearly transmit the teacher's voice and ensure that every student can hear the teacher's explanation, thereby improving teaching effectiveness.

[0003] Chinese Patent CN221863010U discloses a portable megaphone for teachers during class, including a housing. A switch is fixedly installed on the lower side wall of one side of the housing. A wired USB interface is located on the upper part of the side wall near the rear side wall, and a wireless USB interface is located on the upper part of the side wall near the rear side wall. Body slots are formed on both sides of the upper surface of the upper side wall of the housing, near the rear side wall. The other ends of the two body slots are located on both sides of the upper rear side wall of the housing. A limiting plate is fixedly installed at the bottom of the body slots near the rear side wall of the housing. This utility model allows teachers to choose different wearing methods according to their own clothing, making the megaphone more ergonomic. The megaphone does not interfere with the teacher's teaching process while wearing it. Furthermore, the dual-interface megaphone allows for wireless or wired connection, making it more convenient to use.

[0004] The above-mentioned solutions and existing technologies for teacher megaphones have several drawbacks. For example, teachers forget to charge them, which affects the teaching schedule. Furthermore, the wireless headset and megaphone need to be charged separately, which is inconvenient and makes it easy to forget to take the headset. Additionally, the megaphone cannot be placed stably on a desktop. There is a lack of corresponding structures for these issues, which require improvement and optimization. Utility Model Content
