Head-mounted loud-speaking device for aided teaching

Abstract

The invention discloses a head-mounted loud-speaking device for aided teaching. The loud-speaking device comprises a loudspeaker, a battery slot is arranged in the inner wall of the loudspeaker, the outer wall of the battery slot is connected with the inner wall of the loudspeaker; a switch is arranged at outside of the battery slot, the outer wall of the switch is connected with the inner wall ofthe loudspeaker, and a suspension loop is arranged at right side of the switch. The head-mounted loud-speaking device for aided teaching enable the face and the loudspeaker to be more fit through thecooperation of a strut and a roof bar; a clamping shell is placed in the ear, the defects that the learning efficiency of the student is influenced while the traditional head-mounted loud-speaking device for aided teaching easily causes the working fatigue of the auxiliary teaching guidance teacher or maintainer, the learning and use efficiency of the teacher and the student are improved, the teacher is free from producing working fatigue in the lecture, the use expenditure for purchasing the teaching materials is saved, the waste of the teaching material is avoided, and the head-mounted loud-speaking device is suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to a head-mounted sound amplifying device for auxiliary teaching. Background technique [0002] During the teaching process, the math teacher needs to repeatedly explain the exercises, concepts, etc. If the teacher is large, the teacher needs to use a louder voice to ensure that the students in the back row can clearly hear the teacher's voice. The prior art loudspeaker It can amplify the teacher's voice, but the connection between the microphone and the loudspeaker requires the teacher to wear the loudspeaker on the body to use it. In the prior art, for example, the invention patent with application number 201620135630.4 includes Main body, loudspeaker, display screen, operation key board, bluetooth connection device, sound processing device and microphone, the described loudspeaker, display screen and operation key board are respectively embedded in the front face of the lou...

Problems solved by technology

[0002] During the teaching process, the math teacher needs to repeatedly explain the exercises, concepts, etc. If the teacher is large, the teacher needs to use a louder voice to ensure that the students in the back row can clearly hear the teacher's voice. The prior art loudspeaker It can amplify the teacher's voice, but the connection between the microphone and the loudspeaker requires the teacher to wear the loudspeaker on the body to use it. In the prior art, for example, the invention patent with application number 201620135630.4 includes Main body, loudspeaker, display screen, operation key board, bluetooth connection device, sound processing device and microphone, the described loudspeaker, display screen and operation key board are respectively embedded in the front face of the loudspeaker body , the display screen is located above the loudspeaker, the operation button board is located on one side of the display screen, and the Bluetooth connection device is set on the top of the loudspeaker body , the Bluetooth connection device is wirelessly connected with the sound processing device Bluetooth, the microphone is connected to the sound processing device, and is worn on the head side through the sound processing device, although the invention The structure is simple, but there are many deficiencies and defects. In the existing equipment, the design of the sound processing device has defects, the connection between the sound processing device and the microphone is unstable, and the sound processing device cannot be adjusted. The fit between the thin sound processing device and the microphone is not good, and the voice of the speaker instructor will come out. If the face of the instructor wearing it is relatively round, the sound processing device and the microphone will fit the face too tightly, which will cause the wearer's facial discomfort and make the wearer feel uncomfortable. Instructors are prone to fatigue, affect the efficiency of the PA device, cause a waste of teaching aid resources, and increase the school's procurement funds for teaching aids. In view of these situations, in order to avoid the above technical problems, it is necessary to provide an auxiliary teaching With head-mounted loudspeaker device to overcome described defective in the prior art
