Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to headphones, and more particularly to headphones.

Headphones are made of a core material made of elastic sponge or maltplane that presses comfortably against the ears, and a sheet of rubber, vinyl chloride leather, vinyl chloride foam leather using a backing material, or polyurethane sheet. It was covered with an epidermis consisting of

The skin material used for this case has a drawback in terms of breathability, gets stuffy with sweat from the ear skin, and cannot be used for a long time because it gets sweaty, and it also has a problem with the internal and external connections. Due to the lack of communication, the difference in pressure causes abnormal pressure to be applied to the diaphragm of a sounding device such as a speaker, producing abnormal sound and possibly damaging the diaphragm.

However, since this structure that covers the entire ear is required due to the characteristics of the low frequency range of the sounding body, the listener is forced to experience the above-mentioned inconvenience and discomfort.

Furthermore, as mentioned above, the cover material of the header is not breathable, so when the headphone is worn, depending on the shape of the volume formed by the headphone and the ear, it may resonate with a specific frequency from the sounding body. In some cases, this may have an adverse effect on the acoustics.

Therefore, in order to eliminate the above-mentioned drawbacks, some users have added minute holes, such as diameter Q, to the finished fitting.
A plurality of holes of approximately 5,111,111 mm in size were provided to allow communication between the inside and the outside, or the headphones were used by partially shifting the wearing of the headphones, or by covering the outer skin with cloth or the like.

The object of the present invention is to provide a pair of headphones that fits reasonably closely to the ears, does not get wet due to sweat, etc., has stable internal air resistance, and has good acoustic characteristics.

In other words, the present invention uses a soft elastic material such as sponge as the core material, and the outer material of the headphones is covered with a non-woven fabric or knitted fabric, and the surface is made of breathable (breathable) polyurethane. To provide a dosing cover covered with a synthetic resin.

Hereinafter, one embodiment of the present invention will be described in detail.

A headphone 1 is shown in FIG.

This headphone has speaker parts 3 on the left and right sides.
A band 2 is provided across both ears to support these, and a signal line from an amplifier that drives the left and right speakers is connected (not shown). figure).

The pad 4 is composed of an elastic core material 24 that is covered with a sponge or the like in order to softly press the ear, and a skin material 14 that covers the core material 24.

The skin material 14 further includes a surface material 41 made of a material that can clean the surface and remove attached dirt, and a backing material 42 that provides strength and support to this surface material.

With this configuration, the headphone user can be appropriately suppressed by the surface material 41 that contacts the ears and the elastic core material.

Conventionally, the skin material 14 includes a surface material 41 and a backing material 42.
made of rubber or vinyl chloride leather,
Alternatively, it is made of polyvinyl chloride foam leather or a polyurethane sheet to which a suitable backing material 42 is attached, and this is formed by vacuum forming or sewing.

However, these skin materials 14 are not only made of rubber, but even when they are made of foamed synthetic resin, they do not have air permeability across the inside and outside because of the independent cells inside, so it is difficult to see them as a surface material that will be photographed in close-up. In this case, it was not desirable in terms of sweat from the ears or the difference in air pressure between the inside and outside of the headphones.

In the present invention, as is known as synthetic leather, the backing material 42 is made of non-woven fabric, knitted fabric, knitted fabric, etc., and this backing material has breathability. The skin material 14 is formed by applying a polyurethane paint to the surface material 42 and covering it with a surface material 41 which has air permeability by providing a large number of through holes so small that they cannot be seen with the naked eye.

According to the present invention, since the surface that comes into direct contact with the ear, that is, the outer skin material 14, has breathability, stuffiness due to sweat etc. is reduced, thus providing comfort to the user, and allowing the user to wear the ear for a long time while keeping it in close contact with the ear. Not only can it withstand use, but also good characteristics can be obtained for low frequency reproduction due to the close contact.

Furthermore, the air permeability makes it possible to neutralize the difference in air pressure between the inside and outside of the headphone, thereby enhancing the acoustic effect of the sounding body and preventing damage to the ear or the vibrating membrane of the sounding body.

Furthermore, in the present invention, as is known as synthetic leather, deposits such as sweat on the surface material 41 can be easily washed away with water, and its flexibility makes it easy to process, and hardening due to plasticizer transfer. There is little deterioration.

Claims (1)

[Scope of utility model registration request] It consists of a soft elastic core material and a skin material covering the surface of the core material, and the whole is formed into a donut shape so as not to obstruct the sound path of the sounding body, and the skin material is made of nonwoven fabric, knitted fabric, or knitted fabric. A headphone cover comprising a backing material and a polyurethane synthetic resin coating layer provided with breathability by providing a large number of minute diameter through holes.
