TECHNICAL FIELD

[0001] The present application relates to the technical field of earphones, in particular to an earphone. BACKGROUND

[0002] In recent years, with the continuous improvement of living standards, various electronic products have entered people's daily life, becoming an indispensable part of people's work, study and leisure, among which earphones are particularly important. Earphones are a kind of conversion unit that converts the electrical signals received from the self-media player into sound waves that can be heard by the human ear through a loudspeaker. Due to its high portability, small size and other characteristics, earphones are increasingly favored by consumers. At the same time, consumers' demand for earphones is getting higher and higher, and consumers' expectations and requirements for earphones are also constantly improving.

[0003] Among them, open earphones are increasingly accepted by the public, and clip-on open earphones are favored by users due to their small size, comfortable wearing and not blocking the ear. However, due to its small size, it is limited by volume and can only use small-caliber loudspeakers. Small-caliber loudspeakers have small sound emitting areas, which makes the sound leakage more serious than in-ear or semi-in-ear earphones with the same caliber, and cannot achieve ideal sound quality. CONTENT OF THE UTILITY MODEL

[0004] The purpose of the embodiment of the present application is to provide an earphone. By reasonably arranging the position and direction of the sound hole, the sound hole can always point to the ear canal direction after wearing the earphone, so as to realize directional sound transmission into the ear canal and reduce sound leakage to the outer ear.

[0005] To achieve the above purpose, the following technical solutions are adopted in the present application:

[0006] On the one hand, an earphone is provided, which comprises a main body and a clamping assembly, the clamping assembly is installed at one end of the main body and forms a clamping position with the main body that can clamp the human ear, and the end of the main body away from the clamping assembly is provided with a sound hole, and the center line of the sound hole and the central axis of the end of the main body form an included angle a, so that the sound hole always points to the ear canal after the main body is worn on the human ear.

[0007] Further, the included angle a is between 30°-50°.

[0008] Further, the included angle a is 40°.

[0009] Further, the main body is provided with a loudspeaker, and the front cavity of the loudspeaker is in communication with the sound hole.

[0010] Further, an end of the main body is provided with an sound outlet channel, one end of the sound outlet channel is connected with the sound outlet hole, and the other end extends to the front cavity of the loudspeaker.

[0011] Further, the sound outlet channel comprises two opposite parallel surfaces.

[0012] Further, the sound outlet channel further comprises two arc surfaces, one of the arc surfaces connects one end of the two parallel surfaces, and the other arc surface connects the other end of the two parallel surfaces.

[0013] Further, the main body is provided with a sound leakage hole, the sound leakage hole is in communication with the rear cavity of the loudspeaker, and is located on the same side as the sound outlet hole, so that the sound waves emitted by the sound outlet hole and the sound leakage hole can be cancelled out at the overlapping position.

[0014] Further, the rear cavity of the loudspeaker is provided with an inverting component, and the sound waves in the rear cavity of the loudspeaker are inverted by the inverting component and then emitted through the sound leakage hole.

[0015] Further, an included angle β is formed between the center line of the sound leakage hole and the center line of the sound outlet hole, and the included angle β is complementary to the included angle α.

[0016] Further, a first dustproof member is arranged at the sound outlet hole, and / or a second dustproof member is arranged at the sound leakage hole.

[0017] The earphone of the present application has the following advantages: the main body and the clamping assembly are combined to form a structure that can be stably clamped on the human ear. The key is that the sound outlet hole at the end of the main body does not directly face the external space, but forms an included angle α with the central axis of the end of the main body. When the earphone is worn on the user's ear, due to the existence of the included angle α, it can be ensured that the sound outlet hole is always directed towards the ear canal, so that the sound emitted by the loudspeaker can be more directly transmitted into the ear canal, rather than easily leaking to the external environment as in the traditional open earphone. The specific angle design of the included angle α is carefully calculated to ensure that in most cases, regardless of the shape of the user's ear, the sound outlet hole can maintain the best orientation to the ear canal.

[0018] By arranging the position and orientation of the sound outlet hole, the present application significantly reduces the situation of sound leakage to the outside, thereby improving the sound quality experience, which is an important improvement for users who use earphones in public places or want to enjoy music without disturbing others. At the same time, since the sound is more directly transmitted into the ear canal, the user can experience clearer and fuller sound quality, which is a significant advantage for users who pursue high-quality music experience.

DETAILED DESCRIPTION

[0029] In order to make the technical problems solved by the application, the technical solutions adopted and the technical effects reached more clear, the technical solutions of the embodiments of the application will be further described in detail below. Obviously, the described embodiments are only part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the application.

[0030] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] This embodiment provides an earphone, such as Figures 1-6 As shown, it includes: a main body 1 and a clamping component 2. The clamping component 2 is installed at one end of the main body 1 and forms a clamping position 3 between the main body 1 and the main body 1 for clamping a human ear. The end of the main body 1 is provided with a sound outlet 4 on the side away from the clamping component 2. The center line of the sound outlet 4 forms an angle α with the center axis of the end of the main body 1, so that when the main body 1 is worn on the human ear, the sound outlet 4 always faces the ear canal.

[0033] Based on the above scheme, the earphone design aims to solve the sound leakage problem of open earphones, especially clip-on open earphones, caused by the use of small-caliber loudspeakers, and improve the sound quality experience through innovative structural design. The earphone is mainly composed of a main body 1 and a clamping assembly 2. The clamping assembly 2 is installed at one end of the main body 1, and a clamping position 3 capable of firmly clamping the human ear is formed between the main body 1 and the clamping assembly 2, ensuring the stability and comfort of the earphone when worn. What is particularly key is that the end of the main body 1 is specially provided with a sound outlet hole 4 on the side away from the clamping assembly 2, and this sound outlet hole 4 is not designed to directly face the outside space as in the traditional way, but forms a carefully calculated included angle α with the central axis of the end of the main body 1. The design idea is that when the earphone is worn on the user's ear, the included angle α can ensure that the sound outlet hole 4 is automatically adjusted to the position facing the user's ear canal, so that the sound emitted by the loudspeaker can be more directly and efficiently transmitted into the ear canal. This improvement not only significantly reduces the situation of sound leakage to the outside, avoiding the possible disturbance to others when using earphones in public places, but also greatly improves the user's sound quality experience, and the user can feel clearer and fuller sound quality, as if immersed in the world of music.

[0034] It should be noted that the automatic adjustment of the sound outlet hole 4 to the position facing the user's ear canal does not mean that the relative position of the sound outlet hole 4 on the main body 1 is adjustable, but after the earphone is worn on the ear, the sound outlet hole 4 is in the position facing the ear canal, that is, through the included angle α between the center line of the sound outlet hole 4 and the central axis of the end of the main body 1.

[0035] In addition, the design of the clamping assembly 2 also fully considers the wearing comfort of the user, ensuring that the earphone can still maintain comfort when worn for a long time. At the same time, the ingenious design of the included angle α also makes the earphone adapt to different shapes and sizes of ears, improving the universality and user satisfaction of the earphone.

[0036] In summary, the earphone of the present application realizes the effect of directional sound transmission into the ear canal by reasonably arranging the position and orientation of the sound outlet hole 4, not only reduces sound leakage, improves sound quality and wearing comfort, but also provides users with a more high-quality and personalized music experience.

[0037] Optionally, the included angle a between the center line of the sound outlet hole 4 and the axis of the end of the main body 1 is precisely controlled within the range of 30°-50°. This range is selected based on in-depth research on the shape of human ears, wearing habits and sound propagation characteristics. When the earphone is worn on the user's ear, the included angle a ensures that the sound outlet hole 4 can naturally point towards the ear canal, regardless of the shape of the user's ear or the slight movement of the earphone during wearing, and can maintain the best orientation to the ear canal. This design not only maximizes the reduction of sound leakage, avoiding the disturbance to others when using earphones in public places, but also enhances the efficiency of sound entering the ear canal, providing the user with a clearer and fuller sound quality experience. Moreover, the reasonable setting of the included angle a also takes into account the comfort of wearing. Within the range of 30°-50°, the earphone can maintain a natural fit with the ear, reducing the feeling of pressure on the ear, so that the user can remain comfortable even after a long time of wearing. At the same time, this angle range also enhances the universality of the earphone, making it better adapt to different shapes and sizes of ears, meeting the needs of more users.

[0038] Preferably, the included angle a is 40°. Through extensive user research and wearing tests, it is found that when the included angle a is set to 40°, the direction of the sound outlet hole 4 of the earphone can be aligned with the user's ear canal. This design not only ensures that sound can be directly and efficiently transmitted into the ear canal, reducing the attenuation and distortion of sound during transmission, but also maximizes the reduction of sound leakage, avoiding the disturbance to others when using earphones in public places.

[0039] Further, the main body 1 is provided with a speaker 5, and the front cavity of the speaker 5 is in communication with the sound outlet hole 4. The speaker 5 is the core component of sound generation, and the front cavity of the speaker 5 is directly connected with the sound outlet hole 4. This design ensures that sound can be smoothly transmitted from the speaker 5 to the sound outlet hole 4 and accurately enter the user's ear canal. The close cooperation between the speaker 5 and the sound outlet hole 4 further improves the efficiency of sound transmission and sound quality performance.

[0040] In order to more effectively transmit sound from the speaker 5 to the sound outlet hole 4, the end of the main body 1 is specially provided with a sound outlet channel 6. One end of the sound outlet channel 6 is closely connected with the sound outlet hole 4, ensuring that sound can be smoothly transmitted from the channel; the other end extends to the front cavity of the speaker 5 and is in communication with the front cavity of the speaker 5. This design ensures that sound can be directly transmitted from the front cavity of the speaker 5 through the sound outlet channel 6 to the sound outlet hole 4 and accurately enter the user's ear canal. The existence of the sound outlet channel 6 not only optimizes the sound transmission path, but also reduces the loss and interference of sound during transmission, further improving the sound quality performance.

[0041] Importantly, as Figure 5 and Figure 7As shown, the sound outlet channel 6 includes two oppositely arranged parallel surfaces 601. The two parallel surfaces 601 form a structure similar to a "sound channel", which can effectively guide and control the movement direction of sound waves when the sound propagates from the front cavity of the speaker 5 to the sound outlet hole 4. Specifically, the sound waves will be reflected and focused by the parallel surfaces 601 during propagation, so that a relatively concentrated sound beam is formed between the parallel surfaces 601. This sound beam can more accurately point to the user's ear canal, thereby reducing the leakage of sound to the outer ear part. In addition, the design of the parallel surfaces 601 can also reduce the scattering and attenuation of sound waves during propagation, further improving the transmission efficiency and sound quality performance of the sound.

[0042] At the same time, the sound outlet channel 6 also includes two arc-shaped surfaces 602, one of which connects one end of the two parallel surfaces 601, and the other of which connects the other end of the two parallel surfaces 601. By adding two arc-shaped surfaces 602 to connect the two parallel surfaces 601, the sound outlet channel 6 is effectively improved in terms of sound wave diffusion and enhancement, reduction of reflection and interference, and optimization of wearing comfort. This innovative design greatly improves the sound quality performance of the earphone and the user experience.

[0043] In some embodiments, the rear cavity of the speaker 5 is provided with a phase inversion assembly 7. The phase inversion assembly 7 is a device that can change the phase relationship of sound waves, which is usually composed of one or more channels, chambers or diaphragms, for adjusting the phase difference of sound waves during propagation. When the speaker 5 vibrates to produce sound waves, the sound waves will propagate forward (i.e. in the direction of the front cavity and the sound outlet channel 6) and backward (i.e. in the direction of the rear cavity) at the same time. The phase inversion assembly 7 arranged in the rear cavity changes the phase of the backward propagating sound waves, so that it produces a phase difference with the sound waves propagating in the front cavity at a certain frequency. This phase difference will cause interference effect of sound waves in space, thereby changing the distribution and intensity of sound waves.

[0044] Further, the main body 1 is provided with a sound leakage hole 8, and the sound waves in the rear cavity of the speaker 5 are emitted through the sound leakage hole 8 after being inverted by the inversion assembly 7. When the speaker 5 vibrates to generate sound waves, not only the sound waves in the front cavity are transmitted to the user's ear canal through the sound outlet channel 6, but also the sound waves in the rear cavity are emitted outward through the sound leakage hole 8 after being processed by the inversion assembly 7. The inversion assembly 7 plays a key role here, which changes the phase relationship of the sound waves in the rear cavity, so that the sound waves at a certain frequency generate a phase difference with the sound waves in the front cavity. When these inverted sound waves are emitted through the sound leakage hole 8, they will form an interference effect with the sound waves in the front cavity in space, thereby further adjusting and optimizing the frequency response characteristics of the earphone. At certain frequencies, the sound waves in the front cavity and the rear cavity may cancel each other out (i.e., opposite phase), resulting in reduced sound output at these frequencies. At other frequencies, the sound waves in the front cavity and the rear cavity will enhance each other (i.e., same phase), thereby increasing the sound output at these frequencies. Through this interference effect, the earphone can present a more balanced and natural sound quality effect, and reduce sound distortion and overemphasis.

[0045] As an optional embodiment, as shown in FIG. 4, in the scheme without the inversion assembly 7, the forward sound waves in the front cavity of the speaker 5 are emitted through the sound outlet hole 4, and the reverse sound waves in the rear cavity are emitted through the sound leakage hole 8. Since the sound outlet hole 4 and the sound leakage hole 8 are almost arranged on the same side, the sound waves emitted by the two holes will overlap, and the sound waves at the overlapping position will cancel each other out due to opposite phase, thereby reducing the leakage of the earphone, and further improving the privacy. Figure 8

[0046] Further, an included angle β is formed between the center line of the sound leakage hole 8 and the center line of the sound outlet hole 4, and the included angle β is complementary to the included angle α. The design of the included angle β is not arbitrary, but is based on the comprehensive consideration of sound propagation characteristics and earphone wearing comfort. When the included angle α is set to a certain value (such as 40° as described above) to achieve accurate directional transmission of the sound waves in the front cavity, the included angle β as the complementary angle (i.e., 90°-α) can ensure that the sound waves released by the sound leakage hole 8 form the best interference effect with the sound waves in the front cavity in space. Specifically, due to the existence of the included angle β, the sound waves released by the sound leakage hole 8 will propagate in a direction different from the sound waves from the sound outlet hole 4, but there will be an overlapping part of the sound waves emitted from the two holes, so that the sound waves emitted from the sound outlet hole 4 and the sound leakage hole 8 can cancel each other out at the overlapping position, thereby achieving the purpose of preventing sound leakage.

[0047] ​It is worth mentioning that the sound outlet 4 is provided with a first dustproof member 9, and / or the sound leakage hole 8 is provided with a second dustproof member 10. The first dustproof member 9 arranged at the sound outlet 4 is mainly used to block the external dust and dirt from entering the front cavity and the loudspeaker 5. Since the sound outlet 4 is the main channel for sound waves to enter the ear canal, the design of the first dustproof member 9 needs to ensure that impurities are effectively blocked without affecting the propagation of sound waves. The second dustproof member 10 arranged at the sound leakage hole 8 is mainly used to protect the rear cavity and the reversing assembly 7. Although the sound leakage hole 8 is mainly used to release the sound waves in the rear cavity, it is also necessary to prevent dust and dirt from entering to avoid affecting the frequency response characteristics and sound quality performance of the earphone. The first dustproof member 9 and the second dustproof member 10 can be components in the form of filter screens, mesh covers, foam plugs, etc.
