Description

Multi-track physical voice headset structure

The author is related to a multi-track physical sound earphone structure, especially a special opening design on the earphone body, which can achieve the output effect of the multi-track stereo surround sound.

With the continuous advancement of technology, related audio and video electronic products are moving toward the trend of light and miniaturization, providing people with leisure and entertainment that can be used anytime and anywhere. In order to facilitate listening to audio and video information without disturbing others, headphones have become an essential accessory for electronic products. And developed a number of different types: such as earmuffs, ear-hook, head-hook, and in-ear...etc.

Using earphones provides better sound transmission, effectively overcoming the unclearness of sound transmission in the air, especially in noisy environments or intense sports such as in the factory, driving, playing, jogging, etc. The user can clearly hear the sound playing content by carrying the earphone without being affected by the external environment.

However, the various earphone structures used in the past are still not perfect for the design of the sound field. For example, as shown in Fig. 6, the conventional earphone sound hole sheet has only simple and random opening, and generally can only achieve the output effect of ordinary high and low sound stereo. However, it is impossible to provide an output effect that emulates the sound quality of the high-end multi-channel speaker. For the music viewer who pays attention to the sound quality, the existing custom earphone design can not meet the requirements of the music pursuit of the immersive effect, which is the disadvantage.

In view of this, the main purpose of the present invention is to provide a multi-track physical sound earphone structure, the earphone body mainly comprises: a built-in speaker and a connected resonant cavity thereof, characterized in that: at least one low-pitched hole is provided in The middle position of the lower circumference of the resonant cavity; a plurality of high-pitched holes, the interval distribution is disposed at an angle between the middle of the circumference of the resonant cavity, and a plurality of intermediate sound holes surrounding the sound hole plate disposed in front of the speaker, the sound hole In the middle of the plate is a solid piece facing the center of the diaphragm of the horn, and the aperture of the plurality of intermediate holes is arranged downwardly from the bottom to the top, and spaced apart around the periphery of the solid piece; thereby, the headphone body is The special and effective opening design enables the output of the multi-track stereo surround sound like the advanced audio combination.

In order to facilitate the purpose of this creation, structural composition, application function features and functions, further introduction and disclosure, the embodiment is combined with the diagram, as detailed below: Please refer to Figure 1, The utility model relates to a multi-track physical sound earphone structure, which is provided with a headband 9 and a support arm 8 at each end thereof for erecting two earphone bodies 10 having earmuffs 7. The figure is disclosed as an earmuff type. The earphones, because of their comfortable wearing feeling and excellent sound quality, are preferred earphone types for the user, so the embodiment is specifically described as an example, but the actual limit is not limited thereto.

As shown in FIG. 2 to FIG. 4 , the earphone body 10 mainly includes a built-in speaker 20 and a resonant cavity 30 connected thereto, and is characterized in that at least one low-pitched hole 1 is disposed under the resonant cavity 30. The middle position; a plurality of treble holes 3, the spacing is disposed at an intermediate angular position of the circumference of the resonant cavity 30, and a plurality of intermediate sound holes 2 surrounding the sound hole plate 21 disposed in front of the horn 20, the sound hole plate In the middle of 21, a solid piece 22 is directed to the center of the diaphragm of the horn 20, and the aperture of the plurality of intermediate holes 2 is arranged downwardly from the bottom to the top, and spaced apart around the periphery of the solid piece 22; The special effective one of the bass hole 1, the plurality of middle hole 2, and the plurality of high-pitched hole 3 are designed to achieve the output effect of the multi-track stereo surround sound like the advanced sound combination.

Referring to FIG. 2 , when implemented, the solid piece 22 may be integrally formed or formed by a separately attached center piece, and the aperture of the bass hole 1 provided on the earphone body 10 is larger than the middle hole 2 . The aperture is larger than the aperture of the high-pitched hole 3, and the aperture of the low-pitched hole 1 can be between Φ5~7mm; the aperture of the high-pitched hole 3 can be between Φ1~2mm, and the number of the high-soundhole 3 can be basically It is 2~5; the aperture of the middle hole 2 can be between Φ2~5mm, and the number of the middle hole 2 can be 8~20.

Please refer to Figures 3 and 4, wherein the best bass hole 1 on the earphone body 10 can be set to Φ6mm; the optimal aperture of the high sound hole 3 can be set to Φ1.5mm, and the number of the high-pitched hole 3 is set to 3 Approximately 30 degrees apart from the middle to the left and right angles; and the optimal number of midrange holes 2 is 16 The aperture of the single intermediate sound hole 2 above the piece 22 is Φ 2 mm, and the aperture of the single middle sound hole 2 under the solid piece 22 is Φ 4 mm, and is arranged by the two sides of the downward solid solid piece 22, and each layer is separated by a middle sound. The aperture of the hole 2 is sequentially reduced to Φ 0.125 mm, so that the aperture of the solid piece 22 is Φ 3 mm (that is, the upper and lower average aperture) of the middle and right sides; thereby, as shown in FIGS. 4 and 5, The earphone body 10 naturally forms a multi-track layer with a clear output effect, so that the music output by the earphone returns to the normal sound track, and the high, middle and low sounds meet each other in the listener's ear, so that the listener feels free and unrestrained, like The effect of immersive stereo surround sound.

The above is an embodiment of the creation of the earmuff type earphone, but in fact, the creation can also be commonly used on various wireless or wired earphones; in addition to the earmuff type, it can also be set on the earloop. Used on headphones, head-mounted, in-ear, etc. The structural difference is only relative to the size of the opening, which varies with the size of the earphone body; for example, the earphone with the earphone is Φ 3mm, and the average aperture of the middle hole is Φ 1.5. Mm, and the aperture of the high-pitched hole is Φ 0.5mm, but the basic working principle is the same, so no further details will be given here.

In summary, the novel structure of the creation is simple and simple, and it can indeed achieve the improvement of the efficacy, and has the industrial applicability, fully conforms to the patent requirements, and proposes a patent application. The above is only the preferred embodiment of the present invention, and the scope of the present invention cannot be limited by this; therefore, the simple equivalent changes and modifications made by the scope of the patent application and the content of the patent specification are All shall fall within the scope of this patent.
