Abstract

The invention relates to the technical field of teaching equipment, in particular to an English teaching loudspeaker production testing device which comprises a testing box, a base is fixedly installed in the testing box, a pull rod and a sliding seat are slidably connected to the base, the pull rod and the sliding seat are fixedly connected to an end plate, and a main body groove and a headset groove are formed in the sliding seat. The sliding seat is fixedly connected with an end head, the end head is fixedly connected with a reset spring, the reset spring is fixedly connected with a limiting piece, the test box is provided with an insertion groove, the insertion groove is communicated with a limiting groove, a fixed clamping piece is fixedly installed in the limiting groove, and the fixed clamping piece is fixedly connected with a sliding rod; and a movable clamping piece is mounted on the sliding rod in a sliding manner; a loudspeaker testing space is formed by the testing box with the top cover plate, and the passive and active dual-combination noise reduction mechanism is installed on the box wall of the testing box and is used for absorbing medium-high frequency sound waves and low frequency sound waves respectively, so that the quality of the loudspeaker can be comprehensively measured.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to an English teaching loudspeaker production and testing device. Background technique [0002] English is now the world's common language, and it is also the second language that most people in our country learn. English learning is very important. At present, the basic learning of English is mostly carried out through teachers' classroom teaching, especially the pronunciation of English words, which often require teachers to lead students to read aloud, so that students are familiar with the words. [0003] At present, with the expansion of the classroom scale, it is difficult to make the students in the back row hear clearly by relying solely on the teacher's voice, which affects the teaching effect. Therefore, teachers often use loudspeakers in the classroom to ensure the coverage of the sound. During the production process of current teaching loudspeakers, sampling ...
