Description

Open structure earphones with sound tube

technical field

The utility model relates to an earphone, in particular to an earphone with an open structure provided with a sound guide tube.

Background technique

Due to the popularization of various audio-visual products, people have higher and higher requirements on sound quality, and relatively higher requirements on the sound quality of earphones; therefore, in addition to hoping that the earphones can show theater-like effects, they also hope that there will be lingering The sound quality performance of the four sides and the high, medium and low levels are distinct. At the same time, it is hoped that even if it is used for a long time, it will not cause permanent damage to the hearing.

Secondly, from the current structure of earphones, earphones can be roughly divided into two types: closed type and open type. The so-called closed earphone means that through the design of the earphone structure, the sound emitted by the earphone monomer is enclosed in the space between the earphone shell and the human ear, so as not to disperse the sound to the outside; therefore, the closed earphone When in use, it is difficult for people nearby to hear the sound from the earphone; the advantage of the closed earphone is that it can concentrate the sound from the earphone unit to the opening of the ear canal, so it can strengthen the bass effect of the earphone, but the disadvantage is that the earphone The sound is too concentrated in the center of the head, it is not easy to have the feeling of surrounding the sound field, and long-term use may cause permanent damage to hearing. In contrast, the so-called open earphone structure allows the sound from the earphone unit to be heard locally by nearby people. With an open earphone structure, the sound will not be concentrated in the center of the head, and it will not be affected by long-term use. It is less likely to cause damage to hearing, but cannot have high-quality bass performance.

Therefore, in order to enhance the sound quality of the bass, many earphones generally adopt a closed design method, and there are two common closed earphones: the first is a large headphone, which is worn on the head, and the earmuffs cover the ears. The whole cover makes the ear socket of the human ear and the earphone form a closed space, which can improve the bass effect; the second type is the so-called in-ear earphone. The canal-style design method directly inserts the sound output part of the earphone into the opening of the external auditory canal, forming a closed space in the ear canal to make the bass effect more obvious.

However, no matter what kind of closed earphones mentioned above, although they can improve the bass sound quality, there are two common problems: first, such earphones tend to confine the sound field to the center of the head, resulting in partial and unnatural sound distribution; second, , In order to strengthen the bass, this type of earphone seals the earmuffs and the ear into an internal sound field. If it is used excessively for a long time, it may cause permanent damage to human hearing.

In the aforementioned open-structure earphone with a sound guide tube, the sound guide tube is made of a flexible material and has the function of ear hooking.

In the aforementioned open-structure earphone with a sound guide tube, the sound source input unit transmits the sound source signal through the sound source line or wireless communication technology.

In the aforementioned open-structure earphone with a sound guide tube, a cushion is provided at the part where the housing and the sound guide tube contact the human ear.

In the aforementioned open-structure earphone with a sound guide tube, the speaker unit is a high-power speaker unit.

The beneficial effect of the utility model is that it has the effect of combining the advantages of closed and open earphones, can provide high-quality sound quality and strengthen the bass effect, and will not cause hearing damage even if it is used for a long time.

Detailed ways

First of all, please refer to Fig. 1～shown in Fig. 6, the utility model includes:

A casing (10a or 10b), at least one high-power speaker unit 11 is built in, and a first sound output part 12 is formed in front of the speaker unit 11, and a sound chamber is formed in the rear of the speaker unit 11 by the casing 10a 13;

A sound source input unit transmits the sound source signal to the speaker unit 11 through the sound source line (20a or 20b) or wireless communication technology, and the sound source line (20a or 20b) is assembled to the casing 10a or the sound guide tube 30b;

At least one sound guide tube (30a or 30b) is made of flexible material and has the function of ear hook. One end is connected to the housing (10a or 10b) and the connection is located behind the speaker unit 11, and the other end becomes the second Two sound outlet parts (31a or 31b), the inner diameter of the sound guide tube 30b is tapered from the connecting end to the sound outlet part.

In addition, soft pads are provided at the parts where the housing (10a or 10b) and the sound guide tube (30a or 30b) contact the human ear.

Based on the above structure, the utility model adopts the design of an open earphone structure, and one or more high-power speaker units 11 are arranged in the casing (10a or 10b), and there is no closed sound chamber in front of the speaker unit 11. Between the mouth of the human ear canal and the earphone, the sound waves emitted by the speaker unit 11 radiate out from the first sound outlet 12; moreover, the first embodiment of the present utility model shown in Figures 1 to 3, the housing 10a A sound chamber 13 space is formed inside the rear of the speaker unit 11, and is connected with at least one sound guide tube 30a of predetermined length, which extends from the space of the sound chamber 13 to a predetermined position outside the housing 10a, and its function is to turn the speaker unit The back wave discharged by the action of the body 11 first resonates in the space of the sound chamber 13, and then guides the bass out; moreover, the second embodiment of the utility model as shown in Figures 4 to 6 is not yet A sound chamber is formed behind the speaker unit 11 in the casing 10b, but the inner diameter of the sound guide pipe 30b is tapered from the connecting end to the sound outlet, so as to achieve the bass guide equivalent to the first embodiment Effect.

The principle of the utility model is to first use the open earphone structure, set the earphone at a predetermined position next to the human ear, and use a predetermined volume to make the output sound clearly heard, because the middle and high frequency sound has directionality, so , as long as it faces the human ear in a predetermined direction, it can be clearly received; but because the bass has no directionality, it is difficult to completely transmit it to the human ear, so the utility model uses a sound guide tube (30a or 30b) to strengthen the bass The back wave of the action of the speaker unit 11 is transmitted to the opening of the ear canal of the human ear to reinforce the bass effect; and the sound guide tube (30a or 30b) has a predetermined length and diameter, which can quickly and appropriately discharge the back wave to the human ear.

As can be seen from the above, after the back wave resonance at the rear of the speaker unit 11, the low-frequency effect is enhanced, and the volume is also increased, and the sound will be thicker and more powerful than when there is no sound guide tube (30a or 30b); therefore, the utility model It has the advantages of combining closed and open earphones, and provides high-quality sound quality and enhanced bass effect, even if it is used for a long time, it will not cause hearing damage.

The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the utility model, All still belong to within the scope of the technical solution of the utility model.

In summary, the utility model fully meets the needs of industrial development in terms of structural design, practicability and cost-effectiveness, and the disclosed structure also has an unprecedented innovative structure, novelty, creativity and practicability, and meets the needs of industrial development. According to the requirements of the new patent requirements, the application is filed in accordance with the law.
