New Description: [New Technology Field] This creation involves an audio product accessory, especially a tuning mechanism suitable for headphones or speakers. [Prior Art] ^ With the rapid development of high-tech electronic information industry, audio electronic products have become a necessity in people's daily life. Audio electronic products usually need to rely on electronic accessories such as headphones or speakers to play sounds for consumers. Listen to video or music. # However, conventional headphones or speakers are manufactured and tuned to produce products with a certain fixed tone. Taking the earphone as an example, the front case of the earphone is designed with a fixed aperture ratio of the sound hole structure, so that it only produces an auditory feeling. This kind of sound and fixed-sound headphones are far from satisfying the different requirements of different users or the same user when enjoying different music. It can be seen that the conventional fixed-tone earphones cannot meet the real needs of the market. Therefore, there is an urgent need for a tuning mechanism that can be used to adjust the sound of headphones or speakers to solve the above drawbacks. φ [New content] The purpose of this creation is to provide a tuning for the above-mentioned shortcomings of the prior art. The mechanism can be used to mount on a headphone or a speaker to adjust the sound of the earphone or sound box. v In order to achieve the above object, the tuning mechanism provided by the present invention can be docked with the back cover of the earphone or the speaker, and includes a fixed cover and a rotating cover rotatable relative to the fixed cover, the rotating cover is attached to the fixed cover, the fixed cover and the rear cover The shell is butted and the fixed cover is further provided with at least one sound hole combination, each sound hole combination includes a plurality of sound transmission holes, and the rotating cover is provided with at least one tuning hole corresponding to the sound hole combination. 3 M412389 As described above, the tuning mechanism of the present invention can change the position of the rotary cover to cover the number of the sound hole by rotating the rotary cover to control the positional relationship between the upper tuning hole and the sound hole of the fixed cover. The purpose of tuning. In addition, the creation tuning mechanism has the advantages of simple structure and low production cost. [Embodiment] In order to explain in detail the technical contents, structural features, achieved goals and effects of the present invention, the following is a detailed description with reference to the drawings. Referring to the first to second figures, the creation tuning mechanism 1 is for adjusting the tone and docking with the back case of the earphone or the speaker, and includes the fixed cover and the rotating cover 12'. In the specific embodiment, the 'fixed cover u and The spin (4) (1) sentence is a cover structure having a circular top surface, the rotary cover 12 is covered on the cover u and the rotary cover 12 is rotatable relative to the fixed cover 11. A center sound-transmitting hole 11 is opened in the center of the fixed cover n, and a center-timing hole 120 corresponding to the central sound-transmitting hole 11 is opened in the center of the grain-turning cover 12. And the at least one sound hole combination (1) is further disposed on the fixed cover u, and each of the sound hole combination includes a plurality of sound transmission holes U1a. Accordingly, the rotary cover 12 is provided with a soundproof hole combination 11丨 corresponding thereto. At least one tuning hole ΐ 2ι. Preferably, in the present embodiment, the fixed cover U is provided with three sound-transmitting hole combinations 1 Π ′ at equal intervals. Accordingly, the rotating cover 12 is also provided with three tuning holes 121 at equal intervals. Each set of sound-transparent holes is fan-shaped, that is, the sound-transmitting holes 1Ua in each of the sound-transmitting hole combinations ni are arranged in a fan shape, and the tuning holes 12! also have a fan-shaped structure corresponding to the sound-transmitting hole combination ln. — The third to sixth figures show the application of the creation tuning mechanism 1 to the earbuds. The other specific structure of the creation adjustment mechanism 10 and its working principle will be described below by taking the earphone 2 〇 as an example. 9 Referring to the third and fourth figures, the creation tuning mechanism 1〇 and ♦8 single body 21 and the rear case 22 form an earphone type earphone 2〇, wherein the speaker unit η 4 M412389 is located in the tuning mechanism 10 Between the rear housing 22 and the rear cover 22, the outer edge of the fixing cover 11 of the tuning mechanism 10 protrudes to form a card edge 112a. The rear housing 22 defines a card slot 22a for engaging the card edge 112a. The fixing cover 11 is fixed by the above-mentioned engaging structure. On the rear case 22, the edge of the rotating cover 12 extends toward the rear case 22 to form a connecting portion 122. The connecting portion 122 and the rear case 22 are rotatably engaged, so that the fixing cover 11 covers the rotating cover 12 and the rear case 22. between. Referring to the fourth to sixth figures, three different states of the earphone 20 are shown. The three different states correspond to three different aperture ratios of the sound transmission aperture, and the earbud type earphones have three different high frequency response auditory sensations based on the three different aperture ratios. Referring to the fourth figure, when the rotary cover 12 is rotated until the tuning hole 121 is aligned with the sound hole assembly 111 on the fixed cover 11, the sound-transmitting holes 111a on the fixed cover 11 are all exposed, and the fixed cover is transparent. The aperture Ilia has the highest aperture ratio, and the treble component is the strongest when listening to the same music compared to the aperture aperture. Referring to the fifth figure, when the rotary cover 12 is rotated to partially displace the sound-guiding hole 121 and the sound-transmitting hole combination 111 on the fixed cover 11, the partial sound-transmitting hole 111a on the fixed cover 11 is blocked by the rotary cover 12, and Only part of it is exposed, at this time, its treble composition is centered. Referring to the sixth figure, when the rotary cover 12 is rotated until the sound-adjusting hole 121 and the sound-transmitting hole combination 111 on the fixed cover 11 are completely misaligned, all the sound-transmitting holes 111a on the fixed cover 11 are blocked by the rotary cover 12, only The remaining center sound hole 110 is exposed (the center sound hole 110 is always aligned with the center tuning hole 120), and at this time, its treble component is the weakest. As described above, the present tuning mechanism 10 can change the number of the rotary cover 12 to cover the sound transmission hole Ilia by rotating the rotary cover 12 to control the positional relationship between the tuning hole 121 on the rotary cover 12 and the sound transmission hole 111a on the fixed cover 11. The amount of 5 M412389 is achieved by tuning. When the creative tuning mechanism 10 is applied to the earphone 20, by adjusting the rotating cover 12 to cover the multiple holes of the sound-transmitting hole Ilia on the fixed cover 11, different high-frequency response curves can be derived, even if the same audio source is used. Can create different high-pitched auditory feelings. It is worth noting that the creation tuning mechanism is not only common to the structure of earphones, but also commonly used in the structure of various types of speakers. In addition, the number of the sound hole combination and the tuning hole of the tuning mechanism is not limited, the specific number can be adjusted according to specific needs, and the shape is not limited to the fan shape, and a circular, rectangular or irregular shape can be adopted.
