Description

earbuds

This creation is about a type of earphone, especially an in-ear earphone.

According to the common in-ear earphones, most of the sound waves emitted by the speakers are shielded by the inner wall of the casing, and a small part of the sound waves are transmitted to the sound holes through the long tubular sound pipes; , causing poor sound and sound quality, and the problem of sound distortion. Therefore, the author is concentrating on research and using the application of theory, and proposes a creation that is reasonable in design and effective in improving the above problems.

The main purpose of the present invention is to provide an in-ear earphone for solving the conventional earphone, the sound wave emitted by the speaker is easily blocked by the inner wall of the casing, and the problem of sound color, poor sound quality and sound distortion is generated.

In order to achieve the above object, the present invention provides an in-ear earphone comprising: a casing and a sounding unit. The housing is a hollow structure, and the two ends of the housing respectively have a mounting hole and a sound hole. The center positions of the mounting hole and the sound hole are located on the same axis line, and the hole diameter of the mounting hole is larger than the aperture of the sound hole. The sounding unit is fixedly disposed in the mounting hole, and the sounding direction of the sounding unit faces the sound hole. Wherein, the sounding unit and the inner wall of the casing form a sound cavity, and the cross-sectional area of the sound cavity is gradually reduced from the mounting hole toward the sound hole.

The beneficial effect of the creation may be that the sounding unit and the sound hole are disposed in On the same axis, and the cross-sectional area of the sound cavity is gradually reduced from the mounting hole toward the sound hole, the problem that the sound wave emitted by the speaker is shielded by the inner wall of the housing can be effectively reduced, and the sound of the sound output from the earphone is effectively improved. And sound quality.

The following embodiments are intended to further explain the scope of this creation, but do not limit the scope of the creation in any way.

Please refer to FIG. 1 to FIG. 6 together, which is an exploded schematic view of the earphone of the present invention. Such as As shown in FIG. 1 to FIG. 4, the in-ear earphone includes a housing 10, a sounding unit 20, a cover 30, and a mesh body 40. The housing 10 has a hollow structure, and the two ends of the housing 10 have a mounting hole 101 and a sound hole 102. The housing 10 further includes a joint portion 11 and a latching portion 12 adjacent to the mounting hole 101. The housing 10 further includes a fixing portion 13 adjacent to the sound hole 102. The cover unit 20 is fixedly disposed on the joint portion 11; one end of the cover body 30 has an engaging portion 31, and the cover body 30, that is, the through-engagement portion 31 and the engaging portion 12 of the casing 10 are engaged and fixed with each other; One end further includes an outlet hole 301 for allowing the electric wire L of the sounding unit 20 to pass through; and the net body 40 is fixedly disposed at the fixing portion 13 of the housing 10.

Please refer to FIG. 5 , which is a cross section of the housing 10 with the sounding unit 20 and the net body 40 . view. As shown, the center positions of the mounting hole 101, the sound hole 102, and the sounding unit 20 are located on the same axis C, and the hole diameter of the mounting hole 101 is larger than the aperture of the sound hole 102. The sounding unit 20, the inner wall 103 of the casing 10, and the net body 40 are collectively formed with a sound chamber S, and the cross-sectional area of the sound chamber S is gradually reduced from the mounting hole 101 toward the sound hole 102. The sound chamber S is adjacent to the position of the net body 40, and further defines a sound guiding chamber P. The volume of the sound guiding chamber P is smaller than the volume of the other space of the sound chamber S, and the cross-sectional area of the sound guiding chamber P can be the sound chamber. The minimum cross-sectional area of S is the same and is substantially the same as the cross-sectional area of the sound hole 102. Specifically, please refer to FIG. 3 and FIG. 5 together, the sound chamber S formed by the inner wall 103 of the casing 10, the sounding unit 20 and the net body 40 may be similar to a funnel having a curved surface; That is, the edge of the cross section of the sound chamber S may be a circular arc line. As described above, the in-ear earphone 1 of the present invention has a relatively large sound chamber S compared to the conventional earphone, and has a relatively small sound guiding cavity P, which can effectively raise The overall sound and sound quality of the headphones.

Please refer to FIG. 1 and FIG. 6 together. In practical applications, the housing 10 has a mounting hole 101. One end of the sleeve portion 12 may be formed by retraction, and the engaging portion 12 is re-contracted to form the joint portion 11; that is, the housing 10 has one end of the mounting hole 101 and forms a stepped structure inward. The sounding unit 20 can be correspondingly disposed in the engaging portion 11 in the engaging portion. On the other hand, the cover body 30 can be integrally formed with the engaging portion 31, and can be correspondingly engaged with the engaging portion 12 of the housing 10. In a preferred embodiment, the housing 10 is provided. The engaging portion 12 can further include a convex portion 121, and the engaging portion 31 of the cover 30 can have a concave portion 311 corresponding thereto, whereby the housing 10 and the cover 30 can pass through the convex portion 121 and the concave portion 311. The ground is stably engaged and can be further glued to the periphery of the convex portion 121 to strengthen the strength of the engagement and fixation with each other; of course, in practical applications, the engaging portion 12 of the housing 10 may be provided with a recess, and the cover 30 corresponds to Set with a convex part. Similarly, the sound hole 102 of the casing 10 may be retracted to form the fixing portion 13 so that the net body 40 can be engaged with the sound hole 102.

Please refer to FIG. 7, which is another embodiment of the creation, the embodiment and the foregoing The biggest difference between the embodiments is that the sound cavity S formed inside the casing 10 may have an oblique line on the cross section of the sound chamber S; that is, as shown in the cross section of the in-ear earphone 1, the sound The cavity S can assume a trapezoidal shape.

Referring to FIG. 8 , in other implementations, the in-ear earphone 1 may further include There is at least one earplug 50, which may be sleeved on the outer periphery of the housing 10 to assist in making the earphone more conformable to the ear canal of the user; preferably, the earplug 50 may be an elastic body and is detachably The sleeve is disposed on the housing 10, and the user can select different sizes of the earplugs 50 to be sleeved on the housing 10 according to requirements.

The above description is only a preferred and feasible embodiment of the present creation, and thus does not limit the creation. The scope of the patent, so the equivalent technical changes made using this creation manual and the contents of the schema are included in the scope of protection of this creation.
