In order to achieve the above object, the cover system of the present invention has a ring shape, and a card groove is disposed on the inner ring surface, and the adjusting device also has a ring joint portion, and the joint portion is provided with a ring of convex rings for the card groove card. Fixed.

In order to achieve the above object, the cover of the present invention is further provided with a receiving portion for supporting the fixed speaker.

In order to achieve the above object, the shielding portion of the adjusting device of the present invention has a protrusion on the shielding portion, and a slope portion is disposed in the accommodating space near the adjusting holes. When the cover body is connected to the adjusting device, the protrusion is along the slope portion. The ramp displacement.

In addition, the object of the present invention is to provide a sound quality adjusting method for an earphone device. To achieve the object, the earphone device of the present invention has a cover body and a casing, and the cover body and the casing are combined to form an accommodation space for the purpose. A speaker is arranged, and a plurality of adjusting holes are arranged in the housing for the receiving space to communicate with the outside, and the cover body is combined with an adjusting device, wherein the adjusting method is: rotating the cover body to interlock the adjusting device, and shielding by one of the adjusting devices The portion selectively blocks the adjustment holes, thereby changing the degree of communication between the accommodation space in the earphone device and the outside.

In summary, the present invention has the following advantages and advantages compared with the prior art: since the present invention has the ability to adjust the internal acoustic wave resonance space of the earphone device to communicate with the outside world, the output of different sound quality effects can be achieved, and the user The most suitable sound quality output performance can be adjusted according to the preference of each type of music. Therefore, the present invention has more variability and can be closer to the user's needs.

Hereinafter, an earphone device with a sound quality adjustment function and a method for adjusting the same according to various preferred embodiments of the present invention will be described with reference to related drawings.

Referring to Fig. 2, there is shown an exploded perspective view of a headphone device having a sound quality adjustment function according to a first embodiment of the present invention. The earphone device 20 of the present invention comprises a housing 21, a cover 22, a speaker 23 and an adjusting device 24. The housing 21 has an accommodating space 211 (please refer to FIG. 3) and a plurality of adjusting holes 212. The accommodating space 211 is connected to the outside of the accommodating space 211, and the adjusting device 24 is movably coupled to the housing 21, and a blocking portion 241 is extended in the accommodating space 211, and the adjusting device 24 is moved. The shielding portion 241 can selectively block, block, or partially block the adjustment holes 212. Further, the speaker 23 is disposed in the accommodating space 211, and is accommodating in a state where sound is generated. The sound pressure is generated in the space 211. In addition, the cover 22 is coupled to the adjusting device 24, and when the cover 22 is rotated by the user relative to the housing 21, the adjusting device 24 is moved.

It can be further seen from FIG. 2 that one end of the housing 21 has a cap shape and thus is formed with an accommodating space 211, and the other end of the housing 21 is provided with an extension tube 213, which is usually provided with the speaker 23. The signal line of the sexual connection is pulled out, and the frequency response can be adjusted according to the design change of the size and volume.

In the present embodiment, the adjusting device 24 includes a shielding portion 241, a joint portion 242 and a convex ring 244. The adjusting device 24 is coupled to the housing 21 by a convex ring 244 (see the 4)) In combination, since the card groove 215 and the convex ring 244 are both annularly arranged and only the non-adhesive fixing is engaged, the adjusting device 24 is rotated relative to the housing 21, and the coupling portion 242 is slightly smaller. It is larger than the annular portion of the speaker 23, and is provided with a ring of convex rings to be fixedly coupled with a latching groove 222 of the cover body 22, so that when the cover body 22 is rotated relative to the housing 21, the adjusting device 24 can also be combined. In addition, the shielding portion 241 extends from the coupling portion 242 along the cap-shaped curved surface of the housing 21, and the shielding portion 241 has a protrusion 243, and the receiving space 211 is adjacent to the adjusting holes 212. A ramp portion 214 is provided for the projection 243 to be displaced along the ramp.

It should be noted that the cover 22 is annular in the embodiment, and a receiving portion 221 is disposed on the inner ring surface in addition to the groove 222 for supporting the fixed speaker 23.

Next, please refer to FIG. 3 to FIG. 6 , which are respectively a schematic diagram and a cross-sectional view of the earphone device with the sound quality adjustment function in the first adjustment state and the second adjustment state. As shown in FIG. 3 and FIG. 4, in the first adjustment state, the shielding portion 241 of the adjusting device 24 does not block any one of the adjusting holes 212. At this time, the airflow in the accommodating space 211 can be four as shown in the figure. The adjustment holes 212 are discharged to the outside of the casing 21, and as shown in FIGS. 5 and 6, when the cover 22 is rotated counterclockwise to interlock the adjustment device 24, the projections 243 of the adjustment device 24 are along the slope portion 214. The slanting portion 241 gradually obscures the adjusting hole 212. In the fifth figure, the shielding portion 241 has blocked the three adjusting holes 212, so that the remaining adjusting hole 212 serves as the accommodating space 211 to communicate with the outside world. And at this time, the protrusion 243 of the adjusting device 24 is displaced to the highest point of the slope portion 214. If the cover 22 is continuously rotated in the same direction, the protrusion 243 of the adjusting device 24 is caused to snap to the back surface of the slope portion 214 so that the blocking portion 241 The adjustment holes 212 are completely shielded. If the cover 22 is rotated in the opposite direction, a slight force is applied to cause the protrusions 243 to return to the slope of the slope portion 214 and slide down.

It is worth mentioning that the earphone device 20 disclosed in the preferred embodiment of the present invention is an earphone type earphone, but the innovative technology can also be applied to an in-ear earphone (or ear canal earphone), but the change is transferred to the system. For those who are familiar with this technology, they can easily think about it, so they will not be described here.

Finally, the present invention further discloses a method for adjusting the sound quality of an earphone device, wherein the earphone device is similar to the earphone device 20 shown in FIGS. 2 to 6 , which is composed of a casing 21 , a cover 22 , and a speaker 23 . And an adjusting device 24, the housing 21 has an accommodating space 211 for receiving the speaker 23, and the housing 21 is provided with a plurality of adjusting holes 212 for connecting the accommodating space 211 with the outside, and the cover 22 is adjusted The device 24 is coupled, and one of the shielding devices 241 extends into the accommodating space 211, and the adjusting method is: rotating the cover 22 to interlock the adjusting device 24, and selecting by the shielding portion 241 of the adjusting device 24 The adjusting holes 212 are shielded to change the degree of communication between the accommodating space 211 and the outside.

In summary, the earphone device with the sound quality adjustment function of the present invention provides the user with the internal adjustment device by rotating the cover body, thereby adjusting the connectivity between the internal resonance space of the earphone device and the outside world to achieve different sound quality output changes. Therefore, the user can adjust the sound quality output performance according to the preference of each type of music. Compared with the conventional earphone device, the earphone device disclosed in the present invention has more variability and is closer to the user's demand. It can be described as an excellent design.
