Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to an earphone. [Prior Art] ❹ [0002] At present, earphones have become one of the most common tools in people's lives and work. When people use headphones, they usually wear headphones and then directly open the corresponding audio files for listening, for example, turning on the computer. The audio file or the audio file in the phone, but sometimes the initial volume may be very large, the user does not have a process from the bass to the treble gradually adapt, which will damage the user's hearing. SUMMARY OF THE INVENTION [0003] In view of the above, it is necessary to provide an earphone that can effectively protect the user's hearing. 0004 [0004] An earphone includes an audio input terminal connected to an audio plug, an audio output terminal connected to the earplug, a spring and a sliding varistor connected to the sliding end of the sliding varistor, the audio output terminal is electrically Connected to the first end of the sliding varistor, the sliding end of the sliding varistor is fixed on the spring, and when the spring is in the initial position, the sliding end is located at or near the first end of the sliding varistor, The sliding end moves in the direction of the second end of the sliding varistor when the spring is compressed. [0005] Compared with the prior art, the earphone increases the resistance between the audio input end and the audio output end through the compression spring, and gradually reduces the resistance value by utilizing the recovery elastic deformation of the spring, thereby controlling the volume to gradually increase. Large, to provide a buffer time to the user during the spring recovery elastic deformation, so that 099116046 Form No. A0101 Page 3 / Total 16 Page 0992028498-0 201143477 The user gradually adapts to the high volume, instead of receiving the high volume immediately, it is effective Protect your hearing. [0007] [0007] [0008] Referring to FIG. 1 and FIG. 2, a first preferred embodiment of the earphone of the present invention includes a body 10, an audio input terminal 20 and an audio output terminal 3? The earphone further includes an audio plug for connecting the audio wheel terminal 20 and an earplug for connecting the audio output terminal 30. Since the audio plug and the earplug are conventional techniques, they are not specifically described and illustrated herein. The body 1 is disposed at an appropriate position of the earphone, depending on the structure of the actual earphone. In other embodiments, the number of audio input terminals and audio wheel outputs may include two or more, and only one of them is described as an example. The body 10 defines a cylindrical spring receiving cavity 12, and a spring 13 is disposed in the spring receiving cavity 12. One side of the spring 13 abuts against the bottom of the spring receiving cavity 12, and the other side is connected with a button 14. By pressing the button 14, the spring 13 can be compressed to move downwardly in the spring receiving cavity 12 to a compressed position (see FIG. 2). After the button y is released, the spring 13 is restored to elastic deformation and The bomb * housing cavity moves up to the initial position (see Figure 1). The body 10 is further mounted with a sliding change _15 in parallel with the spring 13 . The first end a of the sliding varistor 15 is electrically connected to the audio output end 3 of the earphone. The sliding end c of the sliding varistor 15 is electrically connected to The audio input 20 of the headset. The sliding end c of the sliding varistor 15 is also fixed on the elastic body and when the spring 13 is in the initial position, the sliding end c is located at or near the first end A of the sliding varistor 15 When the spring 13 is compressed, the sliding end C is then moved toward the second end (four) side of the sliding varistor 15 099116046 Form No. A0101 Page 4 / Total 16 Page 0992028498-0 201143477. In other words, when the button 14 is not as desired, the resistance between the bottle end 20 and the audio output 30 is the smallest, and when the button is pressed, the audio wheel 20 is The resistance value between the audio output terminals 3〇 gradually increases. [0009] Ο When using, the user puts on the earphone first, and presses the button 14 hard to open the corresponding audio file immediately. Since the resistance value between the audio input terminal and the audio output terminal 30 is maximum after pressing the button 14 Value, so the volume of the earphone is reduced to a lower volume, then the spring 13 automatically recovers the elastic deformation, and it takes a certain time to recover the elastic deformation. During this time period, the audio input terminal 20 and the audio output terminal 3 0 The resistance between the values gradually decreases the volume of the earphone by _, so that the user does not hear a loud sound immediately after wearing the earphone, but the volume gradually increases, so that the human ear gradually adapts to the high volume. Instead of receiving high volume immediately, it can effectively protect your hearing. [0010] ❹ In the above manner, since the button 14 needs to be manually pressed, the operation may not be convenient. Therefore, the present invention further provides another preferred embodiment. Referring to FIG. 3 to FIG. 6, the second preferred embodiment of the earphone of the present invention. The embodiment includes a circular elastic bracket 100 and two earplugs disposed on opposite ends of the elastic bracket 1 . The elastic bracket 100 is disposed on an opposite side of the earplug 200 and is provided with an elastically stretchable accommodating area 300. One side of the accommodating area 300 is fixed to the rectangular accommodating cavity 400, and a sliding varistor 42 is disposed above the accommodating cavity 400. The sliding varistor 420 is disposed in parallel with a spring 430. The first end A of the sliding varistor 420 The sliding end C of the sliding varistor 420 is electrically connected to the audio wheel end 120 of the earphone, and the sliding end c of the sliding varistor 420 is also fixed to the spring 43〇. 099116046 Form No. A0101 Page 5 of 16 0992028498-0 201143477 One end, and when the spring 430 is in the initial position (Fig. 3), the sliding end C is located at or near the first end A of the sliding rheostat 420 One end A, When the spring 430 is compressed, the sliding end C moves toward the second end B of the sliding varistor 420. The inside of the spring 430 is further provided with a pull rod 450. One end of the rod 450 is provided with a stop portion 460, and the other end is fixed on the side wall of the accommodating area 300 away from the accommodating chamber 400, and when the elastic bracket 100 is pulled apart At this time, the stopper portion 460 on the pull rod 450 moves toward the end to which the pull rod 450 is fixed, thereby compressing the spring 430. [0011] When in use, the user first opens the elastic bracket 100 of the earphone to the maximum angle (see FIG. 4), at which time the spring 430 is compressed to the maximum extent, and the resistance value between the audio input terminal 120 and the audio output terminal 140 is at The maximum value, so the volume of the headphones is reduced to a lower level. Then the elastic bracket 100 is worn on the user's head, and the angle at which the elastic bracket 100 is opened (Fig. 5 and Fig. 6) will be between the maximum angle (Fig. 4) and the minimum angle (Fig. 3), and the specific angle is different users. The size of the head is determined. At this time, the stopper 460 on the rod 450 is pulled back a certain distance, and the spring 430 is in a state of restoring elasticity. When it is fully restored to the elastic state (Fig. 6), the audio input terminal 120 is The resistance value between the audio output terminals 140 is at a minimum value. Similarly, the user does not hear a large sound immediately after wearing the earphone, but the volume gradually becomes higher, which can effectively protect the hearing. [0012] wherein the time during which the spring 430 returns to the elastic state can be determined by selecting a spring 430 of a suitable elastic coefficient. In other embodiments, the spring and the sliding varistor can be designed at appropriate positions of the earphone according to actual needs, and do not adhere to the embodiment given by the present invention, as long as the sliding end of the sliding varistor is controlled by the spring when listening to the audio file. Decrease the tone 099116046 Form No. A0101 Page 6 / Total 16 Page 0992028498-0 201143477 The resistance between the frequency input and the audio output can be.
