Description

Technical Field

[0001] The utility model relates to the technical field of reading and amplifying devices, in particular to a reading and amplifying device. Background Art

[0002] As we all know, power amplifier is abbreviated as power amplifier. It generally refers to a basic device in the audio system, commonly known as "loudspeaker". Its task is to amplify the weak electrical signal from the signal source (from the mixer in professional audio systems) to drive the speaker to produce sound. It can also refer to other devices that perform power amplification. Loudspeakers are often used in classroom teaching.

[0003] However, current loudspeakers are usually carried by belts and are not easy to disassemble during use. During teaching, impurities such as chalk dust can easily fly into the speaker holes and other places because they are too close to the blackboard, thus affecting the service life of the product. Therefore, we propose a reading aloud amplification device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3The utility model is a reading and amplifying device, comprising a wireless charging type amplifying device body 1, a first triangular positioning magnet 2 is arranged in the middle of the rear end of the wireless charging type amplifying device body 1, a plurality of first square positioning magnets 3 are arranged at the rear of the wireless charging type amplifying device body 1, a positioning belt 4 is arranged at the rear end of the wireless charging type amplifying device body 1, the positioning belt 4 is provided with a length adjustment block, so that the positioning belt 4 of the reading and amplifying device is easy to adjust the length, a positioning plate 5 is arranged at the front end of the positioning belt 4, a second triangular positioning magnet 6 is arranged in the middle of the front end of the positioning plate 5, the first triangular positioning magnet 2 cooperates with the second triangular positioning magnet 6, and the cooperation mode between the first triangular positioning magnet 2 and the second triangular positioning magnet 6 is as follows: The magnetic force is matched, so that the first triangular positioning magnet 2 and the second triangular positioning magnet 6 are conveniently fixed by magnetic force. A plurality of second square positioning magnets 7 are arranged at the front end of the positioning plate 5. Each first square positioning magnet 3 is matched with the second square positioning magnet 7. The matching mode between each first square positioning magnet 3 and the second square positioning magnet 7 is magnetic force matching, so that the first square positioning magnet 3 and the second square positioning magnet 7 are conveniently fixed by magnetic force. The edges of the wireless charging type sound amplifying device body 1, the first triangular positioning magnet 2, the first square positioning magnet 3, the positioning belt 4, the positioning plate 5, the second triangular positioning magnet 6 and the second square positioning magnet 7 are all arranged in a rounded shape, so that the reading sound amplifying device will not scratch the user when in use.
