Description

Technical Field

[0001] The utility model relates to the technical field of English teaching, in particular to a hearing earphone. Background Art

[0002] English teaching requires comprehensive teaching from the aspects of listening, speaking, reading, writing and translation. Among them, listening and speaking are the more important parts. Students receive the teacher's teaching content through listening, and also learn pronunciation and intonation through listening. They can also cultivate a sense of language and make students speak English more fluently. In the process of listening and speaking English teaching, especially in classrooms with better teaching conditions, students are often asked to wear headphones to listen to the audio content. However, the existing teaching hearing headphones are mostly head-mounted earphones with earmuff structures. The position of the earmuff can be adjusted by sliding the connecting plate on the top. However, students' ears are large and small. Students with larger ears will have their auricles bent by the surrounding earmuffs after wearing them, resulting in discomfort and difficulty in adjusting the earmuff structure to meet the wearing needs. Since teaching hearing headphones are public resources, they are prone to dust accumulation after long-term use, and earwax is prone to accumulation in the area that fits the ear, which can easily lead to cross infection or make the user feel uncomfortable and refuse to wear them. Utility Model Content

[0034] In the embodiments of the present disclosure, as shown in the attached Figure 5 As shown, the outer side of the linkage block 502 is a wedge-shaped block structure, and the inner side of the linkage block 502 is a trapezoidal block structure. The interior of the connecting spring tube 501 is connected to the fixed tube and the movable tube through a spring, and the outer end of the movable tube is fixedly welded to the linkage block 502. When the limit block 4 is pushed toward the middle and the rear inclined surface fits the outer inclined surface of the linkage block 502, it will push the linkage block 502 to move inward. When the wedge-shaped block structure of the linkage block 502 moves backward to avoid the blocking block 602, the linkage block 502 can continue to move backward or move up and down, and the connecting spring tube 501 is driven to move by the linkage block 502, and the lower ear bag 102 is driven by the connecting piece 5 to adjust the distance between it and the upper ear bag 101 to adapt to wearing.

[0035] In the embodiments of the present disclosure, as shown in the attached Figure 4As shown, connecting card plates 202 are welded to the front and rear ends of the inner side of the connecting plate 2 respectively, and a protective cotton plate 201 is clamped between the connecting card plates 202 and the inner side of the connecting plate 2, and the connecting plate 2 is clamped inside the longitudinal slot 1011. The protective cotton plate 201 is clamped to the large connecting plate 2 by using the connecting card plate 202, and the protective cotton plate 201 and the connecting plate 2 as well as the connecting plate 2 and the longitudinal slot 1011 can be separated. The protective cotton plate 201 can be used by one person and is easy to clean. The position that fits the ear hole is cleaner and more hygienic, avoiding cross infection, or refusing to wear headphones because of psychological discomfort caused by sharing headphones with different people. At the same time, a certain distance can be made between the ear and the ear bag to avoid the ear bag fitting too large an area of ​​the ear and causing stuffiness in hot weather.

[0036] In the embodiments of the present disclosure, as shown in the attached Figure 7 and attached Figure 8 As shown, a movable card plate 401 is welded on the outer side of the limit block 4. The limit block 4 is a wedge-shaped block structure as a whole. The inner inclined surface of the limit block 4 fits on the outer inclined surface of the linkage block 502. After pushing the limit block 4 inward, the linkage block 502 is pushed to move, and the movable card plate 401 slides inside the horizontal card groove 601. The horizontal card groove 601 limits the outermost displacement of the movable card plate 401 to prevent the limit block 4 from falling off.

[0037] In the embodiments of the present disclosure, as shown in the attached Figure 4 and attached Figure 8 As shown, a clamping block 602 is welded inside the inner slide rail 6, and a rectangular groove is opened between the upper and lower parts of the transverse clamping groove 601, and the width of the rectangular groove is greater than the width of the movable clamping plate 401. After the limit block 4 is pushed to move, when the movable clamping plate 401 is located inside the rectangular groove, the limit block 4 can move freely up and down. After adjusting the position of the lower ear bag 102, the limit block 4 is synchronously moved and clamped to the corresponding position of the linkage block 502. After the limit block 4 is released, the linkage block 502 is pushed outward by the elastic action of the internal spring of the connecting spring tube 501, and the limit block 4 is also pushed outward. After the movable clamping plate 401 is clamped into the inside of the transverse clamping groove 601, the limit of the limit block 4 is completed to prevent the limit block 4 from falling off, and the through groove 603 is used to meet the up and down movement of the connecting spring tube 501.

By installing the switch key 103 on the right side, students can have sufficient time to turn on the headphones before English class. Most students write with their right hands. When selecting frequency modulation before listening and adjusting the volume during the listening content playback, the left hand adjusting the audio or volume will not affect the normal writing or marking of the right hand, which is more convenient to use. The tuning slot 105 can adjust the volume by sliding up and down, so that the tuning slider 1051 can be adjusted more accurately when it is not visible. Pushing the tuning slider 1051 upwards will increase the volume, avoiding the situation where the volume is adjusted in the opposite direction by rotating the volume to make it too loud and irritate the ears, or the volume is adjusted too low and the playback content is missed. The sound insulation cotton 104 can better isolate the external environment noise and improve the clarity of listening to audio. For students with larger ears, the distance between the lower ear bag 102 and the upper ear bag 101 can be adjusted to meet the students' needs.

[0039] The working principle of this embodiment is as follows: snap the protective cotton plate 201 used by the students into the middle of the connecting plate 2, snap the connecting card plate 201 into the inside of the longitudinal card slot 1011, and after wearing the headgear 1 on the head, adjust the length through the buckle at the top so that the ear bag can be roughly located at the position of the ear hole, then press the limit block 4 toward the middle and push the linkage block 502 to move inward, press the limit block 4 to drive the lower ear bag 102 to move downward, so that the upper ear bag 101 and the lower ear bag 102 can be completely located outside the ear, and the wearing is completed;

[0040] After pressing the power button 3, the earphone is turned on, and the channel used for teaching is received through the left FM knob 3, and the tuning slider 1051 is pushed upward to increase the volume until the user feels that the volume is appropriate.
