RU61492U1 - OPEN HEADPHONE WITH IMPROVED SOUND INSULATION - Google Patents

Abstract

The device is intended for use as open-type headphones with good sound insulation, which can be used in noisy places - in transport, on noisy streets, etc. The device further comprises a soft shell of sound-absorbing material fixed to the earphone housing so that the earphone housing with the speaker is adjacent to the external auditory canal of the user's ear, and soft soundproofing material is located inside the ear and adjoin the user. The technical result of the claimed device is to reduce the penetration of external noise, a good fastening of the headphones on the auricle, versatility, simplicity of design and low cost.

Description

The device is intended for use as open-type headphones with good sound insulation, which can be used in noisy places - in transport, on noisy streets, etc.

Closed-type headphones are widely known in the art (FIG. 5), for example, the Sennheiser HD25-SP1, AKG K 28 NC models, when using which the entire auricle is inside and the soundproof part of the body is adjacent to the flat part of the head. Due to the good fit and thickness, excellent sound insulation is obtained. But the headphones themselves are very bulky and expensive.

The open type dynamic headphones are also widely known in the prior art (FIG. 4), for example, the Sony MDR-201LP, Panasonic RP-HT6EK models, the soundproof part of which is located between the headphone and the auricle.

Their disadvantage is the lack of good sound insulation, because it is difficult to ensure that the soundproofing material adheres to the auricle.

Also, open-type dynamic “plug” type headphones are widely known in the prior art (FIG. 3), the housing in which is adjacent to the external auditory meatus, for example, the Cresyn AXE599 Black, Cresyn LMX-E700 models. The soundproofing shell of such headphones is located inside the auricle, well adjacent to it.

The disadvantage of such headphones is their poor sound insulation, because the thickness of the soundproofing shell is very small.

Closest to the claimed device are earplugs with earbuds (Figure 2), for example, models Shure E3, Shure E2, Philips HE590.

The difference from the claimed device lies in the fit of the soundproof pad. In the well-known “in-ear” headphones, the fit of a soft soundproof pad can be very good and therefore good sound insulation is achieved. They are also lightweight and hold well on the auricle.

The sound from the speaker passes through the sound channel of the earpiece speaker, which is located in the outer ear canal. A soundproof pad is located between the sound channel of the speaker and the external auditory canal.

The disadvantage of such headphones is the dependence of sound quality on the density of the gasket, which cannot be universal for all people with different widths and

the shape of the ear canal. In addition, due to the fact that the sound from the speaker passes through a narrow channel, it is more difficult to provide a wide range of reproduced frequencies.

In the inventive device (Figure 1) good sound insulation is achieved due to the greater volume of soundproofing material, with a worse fit.

The objective of the utility model is to improve the open-type “plug” headphones in order to reduce the penetration of external noise.

This task is achieved due to the fact that the earphone additionally contains a soft shell of sound-absorbing material attached to the earphone body so that the earphone body with speaker is adjacent to the external auditory canal of the user's ear, and soft soundproofing material is located inside the ear and adjoins the user.

The technical result of the claimed device is to reduce the penetration of external noise, a good fastening of the headphones on the auricle, versatility, simplicity of design and low cost.

Device essence

The design of the inventive device (see Figure 1) is simple and consists of a speaker 1, housing 2, soft soundproofing material 3.

Properties of soft soundproofing material 3 to change the volume allows you to automatically adjust it to the structure of any auricle of the user. This ensures versatility.

The device is cheap due to the fact that the only addition to the well-known headphone type “plug” is the presence on the body of a soft soundproofing material 3, which is glued to the body 2. The cost of a soft soundproofing material

3 is low, and therefore practically will not affect the cost of the headphones themselves, which at a price will be comparable to the cheapest type of open-type “plug” headphones.

Principle of use

When using headphones by the user, the body 2 of the headphone with speaker 1 is adjacent to the external auditory meatus 5, and the soft soundproofing material 3 is located inside the auricle 4 and is adjacent to it. Due to this, a reduction in the penetration of external noise is achieved. This allows you to use such headphones in noisy places - in transport, on noisy streets, etc.

The loss of headphones will be prevented by soft soundproofing material 3 resting against the auricle 4. Thanks to this, a good fixing of the headphones to the auricle is achieved.

Claims (1)

An open-type earphone with improved sound insulation, comprising a housing, a speaker, characterized in that it further comprises a soft shell of sound-absorbing material fixed to the earphone housing so that the earphone housing with the speaker is adjacent to the external auditory canal of the user's ear, and the soft soundproofing material is located inside the ear user sink and adjacent to it.
