New Description: [New Technology Field] This creation is about a headphone structure that can replace the sound tube. Especially, the coke can be replaced with different sound tubes according to the requirements, and the distance between the sound tube and the racquet is adjusted. By using different sound tubes to control the effect of the sound quality of the headphones. ^ [Previous Technology], Press, the commonly used earphone structure is usually composed of a casing, a speaker provided in the casing K, and a connector for connecting the speaker; thereby being applicable to related electronic products (such as MP3 player) , mobile phone, personal digital assistant (PDA) or notebook computer, etc., so that the user's earphones can be inserted into the ear to directly transmit sound, without the unclear situation caused by the sound transmitted in the air. Therefore, the user can use the earphone to clearly listen to the sound information provided by the electronic product without being disturbed by the outside world and without interfering with the external environment (for example, sports, driving, intense activities or other noisy environments). - Since different users have different sizes of ear and ear canal, and their sensitivity to sound is different, different users have different preferences for sound characteristics and sound quality. In today's conventional earphone structure, the frequency response curves of most headphones are fixed. If the user wants to change the frequency response of the high or low part of the signal, usually only by electronic equalizer or related software. Support to change the distribution characteristics of the sound field. If the user's electronic products are not equipped with these devices, the frequency response of the headphones cannot be changed. However, when the electronic device is installed, it is required to be electronic. To install and set up, so, the loss of ^ (4) inductance or the loss of time caused by the loss of the meaning of the addition. The bite can replace the earphone structure of the sound tube, so that the effect of controlling the sound quality of the earphone will be the result of the creation, and how to create a sound tube that can be used to actively expose the sound tube.

Each of the sound tubes 2, 2a, 2b has a channel portion 21, 21a, 21b communicating with the casing (1), and is provided with a rib 22 at each of the sound tubes 2, & 22a, thin, in order to facilitate the replacement, as the name «^υυΐ7〇=" and the sounds f 2, 2a, 2b are provided with the groove portions 23, 23a, 23b. For the inner edge of the hole 14 please refer to "4, 5, 6 and 7", which is a sectional view of the use case, a sectional view of the second use case of the creation = a sectional view of the two use cases, and each use of the present creation. The material f of the example should be shown. If you are not using this book (please refer to both the second and the second figure), you can replace the different sound tubes 2, 2 & 215 according to your needs. The sound tube 2' having a length of 10.5_ is directly inserted into one of the sound holes 14 of the earphone unit 1 when assembled, and is squeaked with the washer 141. After that, the distance between the sound tube 2 and the horn 12 is 2 mm, and when the horn 12 is actuated, most of the gas that is moved to the rear is not generated in the rear chamber of the casing n (inside the back cover ι 3). Resonance, but directly discharges the gas through the channel portion 21 of the sound tube 2, at this time, the bass of the speaker 12 performs poorly, but relatively speaking, the user feels a distinct high pitch range due to the deterioration of the bass. If the sound tube 2a having a length of 8.5 mm is used in the second use example, the force is applied directly to the rib 22 of the originally used sound tube 2, and the sound g 2 is output from the rear sound hole 14 Removed, and then combined with another sound tube 2a in the sound hole 14 after the first use case, so that the distance between the sound tube 2a and the horn 12 will increase to 4 mm, and When the horn 12 is actuated, a part of the gas pushed to the rear will resonate after the casing 11 and the other part will be directly discharged through the channel portion 21a of the sound tube 2a, so that the performance of the bass is superior to that in the first use case. The sound tube 2 is 1〇5nim in length. 7 M400170 In addition, if the sound tube 2b with a length of 5.5 mm is used as the third use case (the method of replacement is as described in the first and second use cases above), the distance between the sound tube 2b and the sigma octave 12 will increase. When it is 7mm, and the gas is pushed to the rear, the gas pushed to the rear will be resonated after the sound chamber of the casing 11, and then discharged from the channel portion 21b of the sound tube 2b. At this time, the bass performance For the best. Please refer to Figure 7 again. The frequency response curves a, b, and c in the figure correspond to the sound tubes 2, 2a, and 2b of different lengths respectively. When the user uses the sound tube 2 of the longer length (10.5mm) The sound tube), when the distance between the sound tube 2 and the horn 12 is shortened, the poor performance of the low range, but also because the bass relative / 0 is suppressed, so that the feeling of the middle and high range is relatively obvious; The shorter sound tubes 2a, 2b (8.5mm and 5.5mm sound tubes), so that the distance between the sound tubes 2a, 2b and the racquet 12 becomes longer, the better the performance of the low range, the relative user Because the bass becomes better, I feel that the mid-high range performance is not so obvious, and the 500Hz or less is generally referred to as the bass. Therefore, it can be seen from the seventh figure that the sound below 500Hz is indeed due to the sound tubes 2, 2a, 2b and the speakers. The distance of 12 changes, and there are obvious differences. · 旷 As mentioned above, this creation is fully in line with the three requirements of the patent: novelty, advancement and industrial availability. In terms of newness and progress, this creation adjusts the distance between the sound tube and the αα8 by changing the different sound tubes according to the requirements, so that when the uu8 is activated, the gas pushed to the rear will be Different resonances are generated behind the casing, and then discharged by the sound tube to adjust the output of the mid-high range and the bass, thereby achieving the effect of adjusting the sound quality of the headphones by using different sound tubes; in terms of industrial availability, Use the products derived from this creation to fully meet the needs of the current market.
