[Technical field to which the invention belongs]

 The present invention relates to a type of headphone, in which two opposite wall plates are provided in the headphone body, and a sound insulating plate is attached to the wall plate, and the sound insulating plate is rotated to adjust the sound output direction in the front-back direction of the speaker Regarding what you can do.

[0002]

[Prior art]

 In general, the headphone has an earphone body connected to the inside of both ends below a single arc-shaped and elastic headband, the earphone body is a flat circular case, one speaker is mounted inside, and the earphone body is One earpiece is fitted into the opening, and the device inputs signals to the speaker inside the earphone body by inserting a lead wire connected to the speaker inside the earphone body into the horn jack of the sound device with an input plug. And a speaker transmits sound.

In general, a speaker of a headphone is mounted in an earphone main body, and the function of the earphone main body is simply to incorporate the speaker. Regarding sound quality, the speaker is attached to the earphone main body and hits around the ear. The effect of fixing the quality is achieved by isolating the sound generated by the speaker and the outside world with the earpiece, which is a part, and fixing the quality.The sound quality is only adjusted by the mixer of the acoustic device, and the speaker The quality of the sound it produces was fixed and could not be adjusted. For people with relatively high pitch, well-known headphones did not provide the same effect for both ears, so they couldn't get the satisfaction of listening to music.

The sound output effect of the headphones is divided into a front airflow and a rear airflow. The front airflow of the well-known headphones is an audio effect generated in front of the speaker, and the rear airflow is an audio effect generated in the back of the speaker. . However, since both ends of the earphone body of the well-known headphones are open and fixed, the effects at the time of shipment cannot be modified, and therefore, individual effects cannot be changed. The necessary adjustments could not be made in order to combine with the pitch of the sound, so it was not ideal for use, and improvement was awaited.

[0005]

[Problems to be solved by the invention]

 According to the present invention, in a headphone, two opposing wall plates are provided in the earphone main body, a sound insulating plate is attached to the outside of the wall plate, and the sound insulating plate is rotated, so that the front and rear of the speaker are moved. An object of the present invention is to make it possible to adjust the sound output effect of the air.

[0006]

[Means for Solving the Problems]

 The invention according to claim 1 is characterized in that an earphone body is provided at both lower ends of an arcuate and elastic headband, the earphone body is a flat circular case body, and a speaker is mounted therein, and the earphone body is provided. In a headphone in which a flexible ear pad is fitted in the opening of the headphone, two opposing wall plates are provided in the earphone body, a plurality of sound output holes are provided in a ring shape, and It is attached between two wall boards, and two long grooves are provided on the circumferential surface of the earphone body, and the openings of the two long grooves are located outside the two wall boards and can be rotated outside the two wall boards A sound insulation plate is provided, a sound adjustment hole corresponding to the sound output hole is provided in the sound insulation plate in a ring shape, and one adjustment knob is provided protruding around the sound insulation plate, and the adjustment knob is provided in the long groove of the earphone main body. Project further out of the earphone body By moving the adjustment knob along the long groove, the sound insulation plate is rotated, and the sound output effect of the front and rear air force of the speaker can be adjusted according to the amount of displacement between the sound adjustment hole and the sound output hole. The headphone is configured as described above.

[0007]

[Embodiment of the invention]

 As shown in FIGS. 1 and 2, an earphone body 2 is provided at both lower ends of an arcuate and elastic headband 1, the earphone body 2 is a flat circular case body, and a speaker 3 is mounted therein. In a headphone in which a flexible ear pad 4 is fitted in the opening of the earphone main body 2, two opposite wall plates 21 are provided in the earphone main body 2, and a plurality of ring-shaped outlets are provided in the earphone main body 2. A sound hole 211 is provided, the speaker 3 is mounted between the two wall plates 21, and two long grooves 22 are provided on the circumferential surface of the earphone main body 2, and the openings of the two long grooves 22 are formed. A rotatable sound insulating plate 5 is provided outside each of the two wall plates 21, and a rotatable sound insulating plate 5 is provided on each of the two wall plates 21 so as to correspond to the sound output hole 211. Around the sound insulating plate 5 52 is protrusively provided, the adjustment knob 52 is protruded outside the earbud 2 protrude respectively from the long groove 22 of the earphone body 2.

In the present invention, the sound insulating plate 5 is rotated by moving the adjusting knob 52 along the long groove 22 to shift the positions of the sound adjusting holes 51 and the sound output holes 211. By expanding or contracting the communication portion, the sound output effects of the front and rear airflows of the speaker 3 can be adjusted, and appropriate adjustments can be made in accordance with the sound pitch of the individual. is there.

The sound insulating plate 5 in front of or behind the speaker 3 is adjustable, and the sound insulating plate 5 behind the speaker 3 is adjusted to enlarge or reduce the sound output hole 211 of the rear wall plate 21. You can increase or decrease the pre-breath. Conversely, by adjusting the sound insulation plate 5 in front of the speaker 3 to enlarge or reduce the sound output hole 211 of the front wall plate 21, the rear air force can be increased or decreased. In this way, by adjusting the two sound insulation plates 5 at the same time, it is possible to convert to different output airflows and to meet individual demands.

[0010] Furthermore, a scale is formed on the outer surface of the two long grooves 22 of the earphone main body 2 so that the magnitude of the output of the front airflow or the rear airflow can be measured, whereby the user can adjust the airflow. It is convenient to use and convenient in use.

[0011]

[Effect of the invention]

 According to the present invention, in a headphone, two opposing wall plates are provided in the earphone main body, a sound insulating plate is attached to the outside of the wall plate, and the sound insulating plate is rotated, so that the front and rear of the speaker are moved. The sound output effect of the airflow can be adjusted, thereby achieving the effect that the sound output can be adjusted according to individual requirements.
