Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
As shown in fig. 1-4, in one embodiment, a headset 10 is provided that includes a body 100, a first earpiece 200, and a second earpiece 300, the body 100 including a speaker 130 (shown in fig. 9). As shown in fig. 1 and 3, the first earplug 200 is of a soft structure and can be assembled to and disassembled from the body 100, and when the first earplug 200 is assembled to the body 100, the distance between the end of the first earplug 200 away from the body 100 and the end surface 121 of the body 100 is L1 (shown in fig. 11). As shown in fig. 2 and 4, the second earplug 300 is of a soft structure, can be assembled to the body 100 and disassembled from the body 100, when the second earplug 300 is assembled to the body 100, the distance between the end of the second earplug 300 away from the body 100 and the end surface 121 of the body 100 is L2 (shown in fig. 13), and L2 is greater than or equal to L1; in a state where the second earplug 300 is mounted to the body 100, the inner cavity of the body 100 can communicate with the outside, so that the earphone 10 has a venting function. When the first earpiece 200 is assembled to the body 100, the earphone 10 is a half-in-ear earphone, and as shown in fig. 5, when the user wears the earphone 10, the first earpiece 200 enters the ear canal 20, so that the depth of the earphone 10 entering the ear canal 20 is shallow. When the second earpiece 300 is assembled to the body 100, the earphone 10 is an in-ear earphone, and when the user wears the earphone 10, the second earpiece 300 enters the ear canal 20 and the earphone 10 enters the ear canal 20 to a greater depth, as shown in fig. 6.
As shown in fig. 7 and 8, when the user normally wears the earphone 10, the speaker 130 of the earphone 10, the body 100 of the earphone 10, the ear canal 20 and the tympanic membrane 30 form a cavity, which is referred to as an earphone front cavity 40. The acoustic properties of the earpiece front cavity 40 directly affect the acoustic performance of the earpiece 10. The acoustic properties of the earphone front cavity 40 mainly include the front cavity volume and the air tightness, and the acoustic performance of the earphone 10 mainly includes the frequency response and the resonance frequency. The air tightness of the earphone front cavity 40 of the half-in-ear earphone and the in-ear earphone is significantly different, and thus the acoustic performance of the half-in-ear earphone and the in-ear earphone is significantly different under otherwise identical conditions. By changing the air tightness of the earpiece front cavity 40, i.e. the air tightness within the ear canal, the acoustic performance of the earpiece 10 can be changed.
The earphone 10 of the present application can change the depth of the earphone 10 into the ear by detachably mounting the first earphone 200 or the second earphone 300 on the main body 100, so that the earphone 10 can be switched between a half-in-ear type earphone and an in-ear type earphone, and the acoustic characteristic of the earphone front cavity 40 can be adjusted, thereby adjusting the acoustic performance of the earphone 10. The first earplug 200 is installed in the main body 100, the earphone 10 is a half-in-ear earphone, and when the user wears the earphone 10, the part of the first earplug 200 enters the ear canal 20, so that the ear canal 20 is not pressed and is not easy to fall off, and the wearing feeling of the user is good. The first earplug 200 enters the ear canal 20, can be well matched with the ear canal 20, and has a good sound insulation effect, so that the air tightness of the front cavity 40 of the earphone is good, and the acoustic performance of the earphone 10 is improved. The second earplug 300 is installed in the main body 100, the earphone 10 is an in-ear earphone, and when the user wears the earphone 10, the part of the second earplug 300 enters the ear canal 20, so that the ear canal 20 is not pressed and is not easy to fall off, and the wearing feeling of the user is good. The second earplug 300 is installed in the main body, and the air-tightness of the front cavity 40 of the earphone can be reduced by the air-release hole, so that the air pressure difference between the inside of the ear canal 20 and the outside is avoided, thereby preventing the sound during speaking from forming echo in the ear canal 20 and improving the sound quality of the earphone 10. The second earplug 300 is assembled to the body 100 with a smaller depth of insertion than the conventional in-ear type earphone, so that it is possible to improve the problem of the intrusion feeling when the user wears the earphone 10. The airtightness of the earphone front cavity 40 is close in the state where the first earpiece 200 is mounted to the main body 100 and in the state where the second earpiece 300 is mounted to the main body 100, so that the earphone 10 has similar acoustic characteristics in both states, and the sound quality of the earphone 10 in both states is not easily affected.
