Therefore, in view of the above-mentioned shortcomings, the applicants of this new type have collected relevant information, and through multi-party evaluation and consideration, and through years of experience in the industry, through continuous trial and modification, they have designed such excellent sounds. A new patent for the structure of headphones with a sense of space.

The main purpose of the present invention is to allow the sound emitted by the speaker elements on the mounting portion to be directly received into the eardrum through the ear canal through the oblique design of the mounting portion, thereby effectively improving the sound quality.

Another main purpose of the present invention is to optimize the pressure ratio of the chambers on both sides of the fixed seat through the tuning (tuning paper) design on the perforations, and the generated sound will be in the sound field space. Produces physical reflections for a better sound field feel.

The main structure of the present invention capable of achieving the above object includes a fixing seat whose one side of the fixing seat is defined There is a sounding portion, and the fixing seat defines a mounting portion extending obliquely from one side of the fixing seat to the other side at a side facing away from the sound emitting portion, and an extension is formed between the mounting portion and the sound emitting portion. Further, a plurality of perforations are formed on the extension portion, and each of the perforations is provided with a tuning member, and the tuning member is a mask perforation; and the mounting portion is further provided with a speaker element; and the sounding portion and the A sound field space is defined between the mounting portions; thereby, when the user uses the new earphone, the sound generated by the speaker element is allowed to directly enter the ear canal of the user due to the tilting design of the mounting portion. The inner tympanic membrane enhances the sound quality. In addition, the sound emitted by the speaker component is physically reflected in the sound field between the sounding portion and the mounting portion, making the whole scene more live during listening. The sense of presence, in addition, when the sound emitted by the speaker element travels in the direction of the extension, the pressure of the sound is not directly passed through the perforation due to the design of the tuning member, so that the sound remains in the sound. In the field of space, it adds to the overall feeling of the sound field.

With the above technology, the isolation between the front cavity and the rear cavity of the conventional earphone may not be completed, and the pressure of the front cavity is flushed to the rear cavity, resulting in a decrease in sound quality, and the original sound cannot be effectively reproduced. The sensation also breaks through the problem of the whole run, and achieves the practical progress of the present invention as described above.
