Background technique

Press, in order to make the earphone have better sound effects, there are many inventions related to the earphone. The general earphone structure includes a shell, a cover, a horn and an outer cover; when the ear canal hole in the human ear is aligned with the horn, the When the direction of the sound is correct, the sound wave with the maximum amplitude can be received; and when the ear canal hole is not aligned with the direction of the sound from the speaker, the amplitude of the received sound wave is small, and the sound effect is poor. However, although the sound of a general horn can smoothly travel to the user's ear, the isolation between the front cavity and the rear cavity of this conventional earphone is not done well, causing the pressure in the front cavity to rush to the rear cavity, resulting in poor sound quality. If it is lowered, the original sound cannot be effectively reproduced, and the sense of sound field is completely lost.

How to solve the above-mentioned conventional problems and deficiencies is the direction that applicants and relevant manufacturers engaged in this industry want to study and improve.

Utility model content

Therefore, the applicant of the present utility model, in view of the above-mentioned deficiency, collects relevant information, evaluates and considers through many parties, and uses years of experience accumulated in this industry, through continuous trial and modification, to design this kind of excellent The structure of the earphones with a sense of space in the sound field.

The main purpose of the utility model is: through the inclined design of the installation part, the sound emitted by the speaker assembly on the installation part can be directly received by entering the tympanic membrane through the ear canal, so as to effectively improve the sound quality.

Another main purpose of this utility model is to optimize the pressure ratio of the chambers on both sides of the fixed seat through the design of the tuning parts on the perforation, and the generated sound will produce physical reflection in the sound field space. , so that it has a better sense of sound field space.

The main structure of the utility model that can achieve the above-mentioned purpose includes a fixed seat, one side of the fixed seat defines a sound outlet, and the fixed seat defines a sound outlet from one side of the fixed seat to the other side at the side away from the sound outlet. The installation part extending obliquely, and an extension part is formed between the installation part and the sound outlet part, moreover, several perforations are formed on the extension part, and a tuning piece is provided on each of the perforations, and the tuning piece is a shielding through hole ; In addition, there is a speaker assembly on the installation part. Moreover, a sound field space is defined between the sound output part and the installation part.

After adopting this technical solution, when the user uses the earphone, the sound produced by the speaker assembly will allow the sound to directly enter the tympanic membrane in the user's ear canal due to the inclined design of the installation part, thereby improving the sound quality. In addition, the sound emitted by the speaker component will be physically reflected in the sound field space between the sound output part and the installation part, so that the overall sense of presence is more present when listening to the scene. Furthermore, the sound emitted by the speaker component When the sound is moving towards the extension part, due to the design of the tuning piece, the pressure of the sound will not pass through the perforation directly, and it will be blocked, so that the sound remains in the sound field space, which increases the overall sound field feeling .

Through the above technology, the isolation between the front cavity and the rear cavity in the conventional earphones is not done well, causing the pressure in the front cavity to rush to the rear cavity, resulting in a decrease in sound quality, and the original sound cannot be effectively reproduced. The problem of the feeling of running away is also broken through.

detailed description

In order to achieve the above-mentioned purpose and effect, the technical means and structure adopted by the present invention will be described in detail in conjunction with the accompanying drawings for the preferred embodiments of the present invention. Its features and functions are as follows, so that it can be fully understood.

As shown in Figures 1 to 3, the structure of the headset includes:

One ear muff 1;

A fixing seat 2 combined with the earmuffs 1 defines a sound output part 21 on one side, and a mounting bracket extending obliquely from one side of the fixing seat 2 to the other side is defined on the side away from the sound output part 21. part 22, and an extension part 23 is formed between the installation part 22 and the sound output part 21, and a sound field space 24 is defined between the sound output part 21 and the installation part 22;

A rear cover body 3 located on one side of the fixing seat 2, the rear cover body 3 is provided with an outer cover body 4 at the side away from the fixing seat 2;

Several perforations 231 formed on the extension portion 23;
