Earphone

Technical Field

The application relates to the technical field of earphones, in particular to an earphone.

Background

In recent years, along with the continuous improvement of living standard, various electronic products are continuously introduced into daily life of people, and become an indispensable part of work, study and leisure of people, wherein headphones are particularly important electronic products. The earphone is a converting unit that converts an electric signal received from the media player into sound waves audible to human ears through a speaker. The earphone is more and more favored by consumers due to the characteristics of high portability, small volume and the like, and meanwhile, the demand of consumers for the earphone is higher and higher, and the expected value and the demand of consumers for the earphone are also continuously improved.

The open earphone is accepted by the public, and the open earphone with the ear is popular with users due to small size, comfortable wearing and no ear blocking, however, due to small shape and limited volume, only a small-caliber loudspeaker can be selected, and the sound-emitting area of the small-caliber loudspeaker is small, so that compared with the sound leakage condition of the ear-in or semi-ear-in earphone with the same caliber, the open earphone with the ear-in or semi-ear-in earphone with the small-caliber is more serious, and the ideal tone quality enjoyment cannot be achieved.

Disclosure of utility model

The embodiment of the application aims to provide the earphone, and the positions and the orientations of the sound outlet holes are reasonably arranged, so that the sound outlet holes can always face the direction of the auditory canal after the earphone is worn, thereby realizing directional sound transmission and entering the auditory canal, and reducing sound leakage to the outer ear.

In order to achieve the above purpose, the application adopts the following technical scheme:

On the one hand, the earphone comprises a main body and a clamping assembly, wherein the clamping assembly is arranged at one end of the main body, a clamping position capable of clamping human ears is formed between the clamping assembly and the main body, a sound outlet hole is formed in one side, away from the clamping assembly, of the end part of the main body, an included angle alpha is formed between the central line of the sound outlet hole and the central axis of the end part of the main body, and therefore after the main body is worn on the human ears, the sound outlet hole always faces towards an auditory canal.

Further, the included angle alpha is between 30 degrees and 50 degrees.

Further, the included angle α is 40 °.

Further, a loudspeaker is arranged in the main body, and a front cavity of the loudspeaker is communicated with the sound outlet.

Further, a sound outlet channel is arranged at the end part of the main body, one end of the sound outlet channel is connected with the sound outlet hole, and the other end of the sound outlet channel extends to the front cavity of the loudspeaker.

Further, the sound outlet channel comprises two oppositely arranged parallel surfaces.

Further, the sound outlet channel further comprises two arc-shaped surfaces, one arc-shaped surface is connected with one end of the two parallel surfaces, and the other arc-shaped surface is connected with the other end of the two parallel surfaces.

Further, the main body is provided with a sound discharging hole, the sound discharging hole is communicated with the rear cavity of the loudspeaker and is positioned on the same side with the sound outlet hole, so that sound waves emitted by the sound outlet hole and the sound discharging hole can be offset from each other at an overlapping position.

Further, the back cavity of the loudspeaker is provided with a phase inversion component, and sound waves of the back cavity of the loudspeaker are emitted through the sound release hole after phase inversion of the phase inversion component.

Further, an included angle beta is formed between the central line of the sound discharging hole and the central line of the sound discharging hole, and the included angle beta is complementary with the included angle alpha.

Further, a first dustproof piece is arranged at the sound outlet hole, and/or a second dustproof piece is arranged at the sound leakage hole.

The earphone has the beneficial effects that the main body of the earphone is combined with the clamping assembly to form a structure which can be firmly clamped on ears of a human body. The key point is that the sound outlet hole of the end part of the main body does not directly face the external space, but forms an included angle alpha with the central axis of the end part of the main body. When the earphone is worn on the ear of the user, due to the included angle alpha, the sound outlet hole can be always oriented towards the auditory canal, so that sound emitted by the loudspeaker can be more directly transmitted into the auditory canal, and the sound is not easy to leak into the external environment like a traditional open earphone. The specific angle design of the angle alpha is carefully calculated to ensure that in most cases the sound outlet remains optimally oriented to the ear canal, regardless of the shape of the user's ear.

By arranging the positions and orientations of the sound outlet holes, the application significantly reduces the outward leakage of sound, thereby improving the enjoyment of sound quality, which is an important improvement for users who use headphones in public places or want to enjoy music without disturbing others.

The embodiment provides an earphone, as shown in fig. 1-6, comprising a main body 1 and a clamping assembly 2, wherein the clamping assembly 2 is arranged at one end of the main body 1, a clamping position 3 capable of clamping human ears is formed between the clamping assembly and the main body 1, one side, away from the clamping assembly 2, of the end part of the main body 1 is provided with a sound outlet 4, and an included angle alpha is formed between the central line of the sound outlet 4 and the central axis of the end part of the main body 1, so that the sound outlet 4 always faces towards an auditory canal after the main body 1 is worn on the human ears.

Based on the scheme, the earphone design aims at solving the problem of sound leakage caused by the use of a small-caliber loudspeaker of an open earphone, and the sound quality experience is improved through the innovative structural design. The earphone mainly comprises a main body 1 and a clamping assembly 2, wherein the clamping assembly 2 is arranged at one end of the main body 1, a clamping position 3 capable of firmly clamping human ears is formed between the main body 1, and stability and comfort of the earphone during wearing are ensured. It is particularly critical that the end of the body 1 is purposely provided with a sound outlet opening 4 on the side facing away from the clamping assembly 2, and that this sound outlet opening 4 is not conventionally designed directly towards the external space, but forms a carefully calculated angle α with the central axis of the end of the body 1. This design is coincidental in that the angle α ensures that the sound outlet opening 4 is automatically adjusted to a position towards the user's ear canal when the earphone is worn on the user's ear, so that sound emitted by the loudspeaker can be more directly and efficiently transferred into the ear canal. The improvement not only remarkably reduces the outward leakage condition of sound, avoids the interference to other people when the earphone is used in public places, but also greatly improves the tone quality enjoyment of users, and the users can feel clearer and plump tone quality as if being immersed in the world of music in an immersive manner.

It should be noted that the automatic adjustment of the sound outlet 4 to the position facing the ear canal of the user does not indicate that the relative position of the sound outlet 4 on the main body 1 is adjustable, but that the sound outlet 4 is located at the position facing the ear canal after the earphone is worn on the ear, i.e. by the angle α between the center line of the sound outlet 4 and the center line of the end of the main body 1.

In addition, the design of the clamping assembly 2 also fully considers the wearing comfort of the user, and ensures that the earphone can still keep comfortable when worn for a long time. Meanwhile, the smart design of the included angle alpha also enables the earphone to adapt to ears with different shapes and sizes, and the universality and the user satisfaction of the earphone are improved.

In summary, the earphone of the application realizes the effect of directional sound transmission and entering the auditory canal by reasonably arranging the positions and the orientations of the sound outlet holes 4, thereby not only reducing sound leakage and improving tone quality and wearing comfort, but also providing a better and personalized music experience for users.

Alternatively, the angle α formed between the center line of the sound outlet 4 and the center line of the end portion of the main body 1 is precisely controlled to be 30 ° -50 °, and this range is selected based on intensive studies on the shape of human ears, wearing habits, and sound propagation characteristics. The angle α ensures that the sound outlet opening 4 is naturally oriented towards the ear canal when the headset is worn on the user's ear, and that the optimum orientation to the ear canal is maintained, regardless of the shape of the user's ear or even small movements of the headset during wear. The design not only maximally reduces the leakage of sound, avoids the interference to other people when the earphone is used in public places, but also enhances the efficiency of sound entering the auditory canal, and provides clearer and plump tone quality experience for users. Moreover, the reasonable setting of the included angle alpha also gives consideration to wearing comfort. Within the range of 30-50 degrees, the earphone can keep natural fit with the ear, so that the pressing sense of the ear is reduced, and the earphone can be kept comfortable after being worn for a long time. Meanwhile, the universality of the earphone is enhanced in the angle range, so that the earphone can be better adapted to ears with different shapes and sizes, and the requirements of more users are met.

Preferably, the included angle α is 40 °. Through extensive user investigation and wearing tests, it is found that when the included angle alpha is set to 40 degrees, the direction of the sound outlet 4 of the earphone can be just aligned with the auditory canal of the user. The design ensures that sound can be directly and efficiently transmitted into the auditory canal, reduces attenuation and distortion of the sound in the propagation process, simultaneously furthest reduces leakage of the sound, and avoids interference to other people when the earphone is used in public places.

Further, a speaker 5 is disposed in the main body 1, and a front cavity of the speaker 5 is communicated with the sound outlet 4. The loudspeaker 5 is a core component for sound generation, and the front cavity of the loudspeaker 5 is directly communicated with the sound outlet 4, so that the sound can be smoothly transmitted from the loudspeaker 5to the sound outlet 4, and accurately enter the auditory canal of a user, and the loudspeaker 5 is tightly matched with the sound outlet 4, so that the transmission efficiency and the sound performance of the sound are further improved.

In order to more effectively transfer sound from the speaker 5 to the sound outlet 4, a sound outlet channel 6 is provided in particular at the end of the body 1. One end of the sound outlet channel 6 is tightly connected with the sound outlet 4, so that sound can be smoothly transmitted from the channel, the other end of the sound outlet channel extends to the front cavity of the loudspeaker 5 and is communicated with the front cavity of the loudspeaker 5, and the design ensures that sound can be directly transmitted from the front cavity of the loudspeaker 5 to the sound outlet 4 through the sound outlet channel 6 and accurately enter the auditory canal of a user. The existence of the sound outlet channel 6 not only optimizes the transmission path of sound, but also reduces the loss and interference of the sound in the transmission process, and further improves the tone quality performance.

It is critical that the sound outlet channel 6 comprises two oppositely arranged parallel surfaces 601, as shown in fig. 5 and 7. The two parallel surfaces 601 form a "sound channel" like structure that effectively guides and controls the direction of movement of sound waves as they travel from the front cavity of the loudspeaker 5 to the sound outlet opening 4. Specifically, the acoustic wave is reflected and focused by the parallel surfaces 601 during propagation such that the acoustic wave forms a relatively concentrated acoustic beam between the parallel surfaces 601. The beam of sound can be directed more accurately to the ear canal of the user, thereby reducing leakage of sound to the outer ear part. In addition, the design of the parallel surface 601 can reduce scattering and attenuation of sound waves in the process of propagation, and further improves the transmission efficiency and the sound quality performance of sound.

Meanwhile, the sound output channel 6 further includes two arcuate surfaces 602, one arcuate surface 602 engages one end of the two parallel surfaces 601, and the other arcuate surface 602 engages the other end of the two parallel surfaces 601. By adding two arc-shaped surfaces 602 to connect two parallel surfaces 601, the sound outlet channel 6 is effectively improved in the aspects of sound wave diffusion and enhancement, reflection and interference reduction and wearing comfort level optimization, and the novel design greatly improves the tone quality performance and user experience of the earphone.

In some embodiments the back cavity of the loudspeaker 5 is provided with an inverter assembly 7. The phase inversion assembly 7 is a device capable of changing the phase relationship of sound waves and is typically comprised of one or more channels, chambers or diaphragms for adjusting the phase difference of the sound waves during propagation. When the loudspeaker 5 vibrates to generate sound waves, the sound waves propagate both 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). The phase inversion assembly 7 provided in the rear cavity changes the phase of the sound wave propagating backward so as to generate a phase difference with the sound wave propagating in the front cavity at a specific frequency, and this phase difference causes the sound wave to form an interference effect in space, thereby changing the distribution and intensity of the sound wave.

Further, the main body 1 is provided with a sound leakage hole 8, and sound waves of the rear cavity of the loudspeaker 5 are emitted through the sound leakage hole 8 after being inverted by the phase inversion component 7. When the loudspeaker 5 vibrates to generate sound waves, not only the sound waves of the front cavity can be transmitted into the auditory canal of a user through the sound outlet channel 6, but also the sound waves of the rear cavity can be processed by the phase inversion assembly 7 and then emitted outwards through the sound outlet hole 8. The phase inversion assembly 7 plays a key role in this regard and it alters the phase relationship of the back cavity sound waves so that they are out of phase with the front cavity sound waves at a particular frequency. When these inverted sound waves are emitted through the sound release hole 8, they will form an interference effect with the front cavity sound waves in space, thereby further adjusting and optimizing the frequency response characteristics of the earphone. At certain frequencies, the sound waves of the front and rear chambers may cancel each other (i.e., in opposite phases), resulting in a reduced sound output at these frequencies. At other frequencies, the sound waves of the front and rear chambers will mutually enhance (i.e., in phase) to increase the sound output at these frequencies. By this interference effect, the earphone can exhibit a more balanced, natural sound quality effect, and reduce the situations of sound distortion and over-emphasis.

As an alternative specific embodiment, as shown in fig. 8, in the scheme that the phase inversion component 7 is not provided, the forward sound wave of the front cavity of the speaker 5 is sent out through the sound outlet 4, the reverse sound wave of the rear cavity is sent out through the sound outlet 8, and because the sound outlet 4 and the sound outlet 8 are almost arranged on the same side, the sound waves sent out by the two sound waves overlap, and the two sound waves at the overlapping position cancel each other due to opposite phases, so that the outward sound leakage of the earphone is reduced, and the privacy is further improved.

Further, an included angle β is formed between the center line of the sound discharging hole 8 and the center line of the sound discharging hole 4, and the included angle β is complementary to the included angle α. The design of the angle beta is not arbitrary but is based on a combination of sound propagation characteristics and the comfort of the headset wearing. When the included angle α is set to a specific value (e.g., 40 ° as described above) to achieve accurate directional sound transmission of the front cavity sound wave, the included angle β is used as the complementary angle (i.e., 90 ° - α), so that the rear cavity sound wave released by the sound release hole 8 can be ensured to form an optimal interference effect with the front cavity sound wave in space. Specifically, due to the included angle β, the sound wave released from the sound release hole 8 propagates in a direction different from that of the sound wave from the sound release hole 4, but the sound waves emitted from the two directions have overlapping portions, so that the sound waves emitted from the sound release hole 4 and the sound release hole 8 can cancel each other at the overlapping positions, thereby achieving the purpose of preventing sound leakage.

It should be noted that the sound outlet 4 is provided with a first dust-proof member 9, and/or the sound outlet 8 is provided with a second dust-proof member 10. The first dust-proof piece 9 arranged at the sound outlet 4 is mainly used for blocking external dust and dirt from entering the front cavity and the loudspeaker 5, and the sound outlet 4 is a main channel for sound waves to enter the auditory canal, so that the design of the first dust-proof piece 9 needs to ensure that impurities are effectively blocked from entering on the premise of not affecting sound wave propagation. The second dust-proof member 10 provided at the sound release hole 8 is mainly used to protect the rear cavity and the inverter module 7. Although the sound release hole 8 is mainly used for releasing the rear cavity sound wave, it is also necessary to prevent dust and dirt from entering so as not to affect the frequency response characteristic and the sound quality performance of the earphone. Wherein the first dust guard 9 and the second dust guard 10 may be components in the form of a screen, a mesh enclosure, a foam plug, etc.
