Description

Headphone speaker

The present invention relates to a headphone speaker unit, in particular to a headphone case with an air flow path, so that when the headphone speaker unit is placed in the earphone case, the creation of the air flow path is not blocked.

For traditional earphones, please refer to the Republic of China new patent No. M517497 "Trumpet Monomers and Headphones" or the Republic of China New Patent No. M529998 "Moving Head Piezoelectric Dual Audio Speakers". The headphones of the previous case all have a speaker in the closed accommodating space for vibrating a vibrating membrane to emit sound waves, which are transmitted to the eardrum to emit sound.

However, the headphones of the previous case have the following defects when used:

1. Since the earphone forms a closed space when the earphone is worn on the ear, the sound wave generated by the vibration film will be transmitted back and forth between the earphone and the eardrum, causing the sound wave to cause abnormal pressure on the eardrum, resulting in use. Uncomfortable.

2. The sound wave transmitted back and forth in the ear canal will cause reverse vibration of the diaphragm, so that the sound wave emitted by the diaphragm will be affected, which will cause distortion of the sound quality, especially for the middle and high notes.

The creator of the present invention has therefore filed the invention of the Republic of China Patent Application No. 105138614, "Headphones for Providing Ear Canal Decompression and Improving Natural Sound Quality, and a Method of Making the Same" to solve the deficiency. The case forms an air flow through the earphone body on the earphone body. The road connects the ear canal of the ear to the outside world. When the sound wave generated by the vibrating membrane is reflected from the eardrum, it will not be transmitted back and forth in the ear canal, but will be transmitted from the air flow channel to the outside, thus reducing the abnormal pressure of the sound wave on the eardrum. It is also possible to avoid the power of the sound wave which is reversely suppressed by the reflection of the vibration film, so that the sound quality is distorted.

This creation is to provide a headphone speaker unit suitable for the case. Therefore, this creation is suitable for combining a headphone housing having an air flow path, including:

a pedestal having a positioning portion at the center, a through hole in the positioning portion, the through hole communicating with the air flow path; a vibration unit including a coil and a vibration film, the coil having a penetration portion, the vibration film being connected to the coil The penetration portion is not covered by the periphery, and the coil is placed in the positioning portion, and the penetration portion is correspondingly perforated.

The present invention further proposes a headphone speaker unit, which is suitable for being combined with a headphone casing having an air flow path, the earphone speaker unit comprising:

a pedestal having a positioning portion at the center, a through hole in the positioning portion, the through hole communicating with the air flow passage; a sleeve having a through hole, the sleeve being sleeved on the positioning portion, so that the through hole corresponds to the through hole; a vibration unit comprising a coil and a vibration film, the coil having a penetration portion connected to the periphery of the coil without covering the penetration portion, the coil connecting the sleeve and the corresponding portion corresponding to the penetration portion Through hole and the perforation.

According to the above technical features, the following effects can be achieved:

Since the earphone speaker unit of the present invention does not block the air flow path on the earphone casing, when the sound wave generated by the vibration film is reflected from the ear film, it will not be transmitted back and forth in the ear canal, but will be transmitted from the air flow path to the outside. Therefore, the sound wave can be prevented from being abnormally pressed against the eardrum by the back and forth, and the sound of the sound wave caused by the reverse suppression of the vibration film by the reflection can be prevented, and the sound quality is distorted. Therefore, the earphone speaker of the present invention combined with the earphone made of the earphone casing with the air flow channel can make the eardrum of the human body feel the original state of the sound, instead of the artificial sound field feeling of the current general earphone.

In combination with the above technical features, the main effects of the present earphone speaker unit will be clearly shown in the following embodiments.

The first embodiment of the present creation is shown in the first to fourth figures, including:

a headphone casing (1), an air flow passage (11) penetrating through the earphone casing (1) at a central position; a headphone speaker unit (2), the earphone speaker unit (2) comprising: a base (21) The center has a positioning portion (211), and the positioning portion (211) has a through hole (212), the through hole (212) communicates with the air flow path (11); a vibration unit (22) includes a coil (221) and a vibration film (222) having a penetrating portion (2211) connected to the periphery of the coil (221) without covering the penetrating portion (2211), the coil (221) The positioning portion (211) is placed, and the penetration portion (2211) is correspondingly perforated (212). Thereby, the earphone speaker unit (2) does not block the air flow path (11).

Referring to the fourth and fifth figures, when the earphone casing (1) is worn on one ear, because the air flow path (11) penetrating the earphone casing (1), and the earphone speaker unit (2) are not The air flow path (11) is blocked such that one ear canal of the ear can communicate with the outside. When the audio is played, the coil (221) causes the vibration of the diaphragm (22) to generate a sound wave, and when the sound wave is reflected from the eardrum of the ear, it is transmitted from the air flow passage (11) to the outside. It will not be transmitted back and forth in the ear canal, thereby reducing the abnormal pressure of the sound wave on the eardrum. In addition, since the sound wave is transmitted from the air flow path (11) to the outside, the sound of the sound wave caused by the reverse suppression of the vibration film (22) can be prevented, so that the vibration of the vibration film (22) is affected by the vibration. The quality of the reverse repression causes the sound quality to be distorted.

The second embodiment of the present creation is shown in the sixth figure, including:

a headphone casing having an air flow passage through the earphone casing (not shown) at a central position; a headphone speaker unit (2A), the headphone speaker unit (2A) comprising: a base (21A) having a central portion a positioning portion (211A) having a through hole (212A) in the positioning portion (211A), the through hole (212A) communicating with the air flow path; a sleeve (22A) having a through hole (221A), the sleeve (22A) Nested on the positioning portion (211A), the through hole (221A) corresponds to the perforation (212A); a vibration unit (23A) includes a coil (231A) and a vibration film (232A), the coil (231A) There is a penetrating portion (2311A) connected to the periphery of the coil (231A) without covering the penetrating portion (2311A), the coil (231A) connecting the sleeve (22A), and allowing the wearing The permeable portion (2311A) corresponds to the through hole (221A) and the through hole (212A). Thereby, the earphone speaker unit (2A) does not block the air flow path (11A), and thus the embodiment has the effect as described in the first embodiment.

In view of the above description of the embodiments, the above-described embodiments are merely a preferred embodiment of the present invention, and the implementation of the present invention is not limited thereto. The scope, that is, the simple equivalent changes and modifications made in accordance with the scope of the patent application and the content of the creation of the creation, are within the scope of this creation.
