Description

Headphone structure

Technical field

The present application relates to a headphone structure, and more particularly to a non-earphone type earphone structure. Background technique

Press, the shape of the earphones is diverse, and different types can be distinguished according to the shape, acoustic structure, electroacoustic principle, use or data transmission mode of the earphone. Earphones and earphones are often used to distinguish between headphones, and in the strict product classification, they are collectively referred to as headphones.

The benefits of in-ear headphones are lightweight, and portability is the best in all types of headphones. Because of this advantage, almost all portable electronic devices are equipped with earbuds.

Advantages and Disadvantages of Earphones: Due to the size limitations of the earbuds, there are many design restrictions on the earphones. The sound source is closer to the tympanic membrane, which makes the sound clearer, and the earphones are born. It does bring a different sound quality, excellent earphones, the sound quality performance is not even worse than the headphones that are several times more expensive, but because it is too close to the tympanic membrane, it is the most serious damage to people. In order to pursue a clean listening ring, the earplugs are often designed to completely close the ear canal. It is difficult for the user to hear the sound outside the earplugs. Outdoors, such isolation is not a good thing, and it is too easy to cause an accident. Due to the near-ideal listening environment and lack of reference ambient sound, the sound of earplugs is often unconsciously adjusted to be larger and larger, and the earplugs are tighter and tighter, and the time is long, which is very harmful to hearing. And even forever, several of our friends have become more and more vocal because they are obsessed with in-ear headphones, because their hearing has begun to decline. There was an article that said that in-ear protection is actually protecting the hearing. It is totally irresponsible. It is as shameful as tobacco can cure diseases. In addition, in-ear earphones inevitably bring a stethoscope effect, and the frictional sound of the thread on the clothes is amplified and transmitted to the ear through the wire, which is really annoying.

The ear-hook headphones attach a foldable hook to the earphone so that it can be hung inside the auricle. Earphones using such a suspension system can be counted as ear-hook headphones, also known as ear-hooks. Since the suspension method is not close enough to the auricle, there will always be a problem of leakage, which will degrade the sound quality. Because it is suspended from the auricle, such headphones should not be made very heavy.

The rear-mounted earphones use a flexible headband that clips the earphones around the auricle from behind the head, and the earphones with the earmuffs attached to the auricle are incorporated into the back-mounted headphones. This type of earphone basically does not damage the hair style, especially without damaging the hair style of the men. This type of earphone is not as comfortable as the ear-hook type, but it can make the earmuffs close to the ear, and the problem of leakage is basically non-existent, but Since the headband is generally more elastic, the discomfort will be a little more. This headband is difficult to design to be adaptive. Most of these headphones have an unadjustable headband, too big or too small. Friends, will not be suitable to wear. By With a fixed headband, their portability becomes very general.

The most common type of earphones for headphones, using a flexible headband, sandwiches the auricle from the top of the head. Because of the light weight, the earmuffs are generally designed to be large, and the top earphones are almost full-size. design. This type of earphone is very well developed, and the headband is generally adaptive, and the earmuffs can be rotated in a small amount. These small features make the wearing comfortable. However, it is not suitable for portability. Even if the headband is designed to be foldable, its portability is not better than that of the plug-in type and the ear-hook type.

Accordingly, the present application is an improved earbud headset to provide a non-invasive outer earphone structure for a more comfortable fit and listening quality. Summary of the invention

A speaker 20 and a sound guiding member 30, wherein the housing 10 includes an upper housing 12 and a lower housing 14, and the sound guiding member 30 is used to guide sound waves to the outer ear or even the middle ear and the inner ear to provide Comfortable to wear. This application can also be used for general ear-hook or head-mounted models.

Please refer to FIG. 2 , which is a schematic structural diagram of a speaker according to a preferred embodiment of the present application. As shown, the speaker 20 includes a bottom case 21 , a magnet 22 , a front pole piece 23 , and a voice coil 24 . , a metal ring 25 and a diaphragm 26 . The bottom case 21 is provided with a recess 210 at its central portion, and an annular wall 212 is disposed at an edge thereof. The inner side of the annular wall 212 is a slope 214. The magnet 22 is disposed within the recess 210. The front pole piece 23 is disposed above the magnet 22. The voice coil 24 is disposed above the front pole piece 23. The metal ring 25 is disposed above the voice coil 24. The diaphragm 26 is disposed above the metal ring 25. The metal ring 25 and the diaphragm 26 are fixed on the annular wall 212.

Furthermore, the material shield of the metal ring 25 can be replaced by a ceramic, that is, a ceramic ring. In the existing speaker, since the annular wall 212 has a considerable thickness, the diaphragm 26 is disposed on the annular wall 212, and the size of the diaphragm 26 is necessarily smaller than the diameter of the bottom case 21, so that the sound range is relatively narrower. If you want a wide range of sound, you must expand the size of the diaphragm. In the present application, the bevel 214 is disposed on the annular wall 212 under the same size speaker to reduce the contact area between the vibrating membrane 26 and the annular wall 212, so as to increase the area of the vibrating membrane 26, thereby obtaining a wider range and better sound quality. effect.

Please refer to FIG. 3A and FIG. 3B , which are schematic structural diagrams of the earphone fixing manner according to a preferred embodiment of the present application.
