Description

Externally-placed earphone

Technical Field

The invention relates to the technical field of earphones, in particular to an externally-placed earphone.

Background

Headphones refer to devices that fit around, over, or in the ear and radiate acoustic energy into the ear canal. Headphones come in a variety of forms, including headphones, earphones, headsets, in-the-ear headphones, or sports headphones, and may be wired or wireless. Headphones include an acoustic transducer (typically a speaker) to transduce audio signals into acoustic energy. According to different wearing modes, the earphone is divided into a headset, an in-ear earphone, a bone conduction earphone and an out-put earphone.

The headphone is generally provided with two speaker housings for the right ear and the left ear, and a headband worn on the top of the user's head. Although the headset has good noise reduction, the speaker frame body presses the tragus of the ear, and the defect of poor comfort exists.

In-ear headphones are typically worn by clamping their earplugs to the concha cavities of the ears and against the tragus. Although the in-ear earphone has good privacy, the in-ear earphone presses the tragus when worn, and the problems of uncomfortable use and unstable wearing exist.

When the bone conduction earphone is worn, the loudspeaker part is arranged in front of the earhole of the tragus, so that the sound and the music can be heard without blocking the earhole, the tragus is not pressed, and the bone conduction earphone is comfortable to wear. In the case of listening to music, in terms of the relationship of the vibration output of the bone conduction speaker to the auditory nerve conduction signal via the skin and the cranium of the human body, however, the high-frequency component is greatly attenuated at the time of transmission via the skin, resulting in deterioration of sound quality.

The externally-placed earphone can open double ears, is comfortable to wear, and does not have uncomfortable feelings such as expansion, pressing and the like caused by the in-ear earphone or the headset after being worn for a long time.

FIG. 1 is a schematic diagram of the structure of an auricle. Auricles, also known as "auricles", are a part of the outer ear and are devices that collect sound waves. The majority of it uses elastic cartilage as a scaffold, covered by skin. The drooping part of the lower end of the pinna, which is cartilage-free, consists of skin, connective tissue and fat only, is called the earlobe 11. The auricles are attached to both sides of the skull by ligaments, auricle muscles, cartilage, skin, etc. The anterolateral aspect of the pinna is rugged, its forward curled free edge is named helix 12, with the helix 12 foot rising above the external auricular door. The arch-like elevation in front of and parallel to the helix 12 is called the antitragus 13. The cavity between the earlobe 11 and the helix 12 that opens into the external auricle is called the concha cavity 14. The lesser nodule in front of the concha is called tragus 15 and the protuberance in front of the lower end of the antitragus 13 is called antitragus 16. Referring to fig. 5, where the upper portion of the auricle is connected to the facial skin, the upper root 17 is called the upper root 17, and the upper root 17 is hidden by the ear hook 200 in fig. 5.

In this embodiment, the Z axis represents the up-down direction, the positive direction of the Z axis represents the up direction, the negative direction of the Z axis represents the left-right direction, the positive direction of the Y axis represents the left, the negative direction of the Y axis represents the right, the positive direction of the X axis represents the front-back direction, and the negative direction of the X axis represents the front.

The externally-placed earphone in the embodiment of the present invention will now be described.

Fig. 2 is a schematic diagram of the external structure of the externally-placed earphone. Fig. 3 is a schematic diagram of the internal structure of the externally-placed earphone. Referring to fig. 2, the external earphone includes a rear hook 100, an ear hook 200, a sound emitting component 300, and an optional control circuit 410 and a battery 420. Referring to fig. 2 and 3, the rear hanger 100 includes a first wire housing 110, a first conductive wire 120 and a first elastic wire 130 which are accommodated in the first wire housing 110.

Fig. 4 is a top view of fig. 2. Fig. 5 is a top view of a user wearing an externally placed earphone. Referring to fig. 4 and 5, the rear hanger 100 is configured to be worn by a user and disposed around the rear side of the user's head, and the first elastic wire 130 is used to provide a pair of first elastic forces F that are clamped in opposite directions along the Y-axis ₁ . First elastic force F ₁ So that the two ear-hooks 200 connected to both ends of the rear hook 100 elastically grip the user's head. The first elastic wire 130 is made of at least one of steel wire, memory steel wire and memory nylon, so that the rear hanger 100 can be outwardly expanded under the action of external force and has a certain resilience force to generate a first elastic force F ₁ The clamping force in the arrow direction, and at the same time, the flexibility of the gap between the two ends of the rear hanger 100 can be adjusted to adapt to the head circumference of different sizes. When the user wears the external earphone, the rear hook 100 elastically clamps the user's head so that the external earphone can be stably worn on the user's head.

Referring to fig. 2 and 3, the ear hook 200 includes a second wire housing 210, a second conductive wire 220 and a second elastic wire 230 which are accommodated in the second wire housing 210. Fig. 6 is a schematic diagram of the structure of the ear hook 200 and sound emitting member 300. The ear hook 200 is configured to be worn by a user around the upper ear canal 17 of the user, and the second elastic wire 230 is configured to provide a second elastic force F ₂ Thus, when the user wears the external earphone, the earhook 200 elastically clamps the peripheral side of the upper root 17 of the user so that the external earphone can be stably worn on the head of the user. Wherein the number of ear drops 200 is two. The second wire-receiving shells 210 of the two ear-hooks 200 are respectively connected to two ends of the first wire-receiving shell 110, and the first ends of the second wires 220 of the two ear-hooks 200 are respectively electrically connected to two ends of the first wire 120.

Fig. 7 is an elastically deformed view of the ear hook 200 of fig. 6. The second elastic wire 230 is mainly used for keeping the ear hook 200 in a shape matching with the ear of the user, and has a certain elasticity, so that when the user wears the ear hook, a certain elastic deformation can be generated according to the ear type and the head type of the user to adapt to users with different ear types and head types.

The second elastic wire 230 is made of at least one of steel wire, memory alloy and memory nylon, and has good deformation recovery capability, so that even if the ear hook 200 is deformed by external force, the ear hook can still recover to the original shape when the external force is removed, so that the ear hook can be used by a user continuously.

Alternatively, referring to fig. 2, the first and second wire-receiving

shells

110 and 210 are made of soft rubber, and have good insulation and are elastically deformable.

Optionally, referring to fig. 3, two ends of the first wire 120 are connected to the first socket end 140 so as to electrically connect the second wire 220, and the other end of the second wire 220, which is far away from the first wire 120, is connected to the second socket end 240 so as to electrically connect the sound generating component 300. In this way, the first wire 120 and the second wire 220 are electrically connected to each other for supplying power and transmitting data for the operation of the control circuit 410 by the sound emitting component 300, the control circuit 410 and the battery 420.

Specifically, the first socket end 140 and the second socket end 240 may be made of a hard material, such as plastic.

In the present embodiment, when the first socket end 140 and the second socket end 240 are manufactured, they may be formed at both ends of the first elastic wire 130 or the second elastic wire 230, respectively, by injection molding. In other embodiments, the first connection end 140 and the second connection end 240 may be injection molded, and connection holes corresponding to the ends of the first elastic wire 130 or the second elastic wire 230 may be reserved during injection molding, so that after injection molding, the first connection end 140 and the second connection end 240 may be inserted into the corresponding ends of the first elastic wire 130 or the second elastic wire 230 through the connection holes, or may be fixed by bonding.

Alternatively, the first and second

wire receiving shells

110 and 210 are made of soft rubber, have good insulation, and are elastically deformable. Specifically, the first wire housing 110 may be formed on the peripheries of the first conductive wire 120, the first elastic wire 130 and the first socket end 140 by injection molding, so that the first wire housing 110 is fixedly connected with the first conductive wire 120, the first elastic wire 130 and the first socket end 140, and the first wire housing 110 does not need to be separately formed by injection molding and then further sleeved on the peripheries of the first conductive wire 120, the first elastic wire 130 and the first socket end 140, thereby simplifying the manufacturing and assembling procedures, and in this way, the fixation of the first wire housing 110 is more firm and stable. Similarly, the second wire housing 210 may be injection molded around the second conductive wire 220, the second elastic wire 230, and the second socket 240.

Fig. 8 is a schematic diagram of the external structure of the sound emitting component 300 of the externally-placed earphone according to the present embodiment. Fig. 9 is a cross-sectional view taken along line A-A of fig. 8. Referring to fig. 8 and 9, the sound emitting part 300 includes a first mounting case 310 and an air conduction speaker 320 accommodated in the first mounting case 310. The number of sound emitting components 300 is two and corresponds to the ear hook 200 one to one, i.e. each sound emitting component 300 is connected to a corresponding ear hook 200. Specifically, the air conduction speaker 320 is electrically connected to the second end of the corresponding second wire 220, and one end of the first mounting case 310 is connected to the end of the corresponding second wire housing 210 remote from the first wire housing 110.

Specifically, the air conduction speaker 320 is a moving coil speaker. The front end of the moving-coil loudspeaker refers to the sound-producing end of the moving-coil loudspeaker, and is usually the end where the components such as the vibrating diaphragm or the cone are located, and is close to one side of the sound outlet 311.

Alternatively, the air conduction speaker 320 occupies the inner space of the second end of the first mounting case 310. That is, in the inner space of the first mounting case 310, a portion of the space corresponding to the second end of the first mounting case 310 is almost occupied by the air conduction speaker 320, and the air conduction speaker 320 is large in volume, good in sound quality, and located at the second end of the first mounting case 310 to cover the concha chamber 14, and the emitted sound can be intensively propagated through the air such as the concha chamber 14, with good privacy.

Further, the air conduction speaker 320 occupies 60% to 80% of the inner space of the first mounting case 310.

Specifically, in connection with fig. 3, the control circuit 410 is electrically connected to the air conduction speaker 320 and the battery 420, respectively. The control circuit 410 is configured with the function of controlling the air conduction speaker 320 and the battery 420, and the battery 420 is used to supply power to the control circuit 410 and the air conduction speaker 320.

Optionally, referring to fig. 2 and 3, the externally-mounted earphone further includes a second mounting case 430 and a third mounting case 440. The second mounting case 430 is for accommodating the control circuit 410. The second mounting shell 430 is connected between the rear hanger 100 and one of the ear hangers 200. The third mounting case 440 serves to accommodate the battery 420, and the third mounting case 440 is connected between the rear hanger 100 and the other ear hanger 200.

Referring to fig. 2 and 3, the second mounting case 430 is located between the rear hanger 100 and the right ear hanger 200, and the third mounting case 440 is located between the rear hanger 100 and the left ear hanger 200.

It is understood that in other embodiments, the external earphone is not provided with the second and third mounting

cases

430 and 440, and the control circuit 410 and the battery 420 may be provided in the first wire housing 110, the second wire housing 210, or the first mounting case 310 independently of each other.

Optionally, an air conduction microphone 330 is installed in the first installation housing 310 of one sound generating component 300, a bone conduction microphone 340 is installed in the first installation housing 310 of the other sound generating component 300, the control circuit 410 is respectively electrically connected with the air conduction microphone 330 and the bone conduction microphone 340, and the control circuit 410 is configured with functions of knowing environmental scene information through the air conduction microphone 330 and the bone conduction microphone 340 and controlling the start and stop of the air conduction microphone 330 and the bone conduction microphone 340.

In a typical environment, the use of an air conduction microphone 330 (e.g., a MEMS microphone) is good for receiving human voice and for noise reduction. In a noisy environment, bone conduction microphone 340 receives sound through vibration, enabling better reception of human voice. The control circuit 410 obtains the ambient sound through the air conduction microphone 330 and the bone conduction microphone 340, and determines whether the surrounding environment is in a noisy environment or a general environment, so that the appropriate microphone is selected to receive the sound. The control circuit 410 obtains that the environmental scene is the prior art through the microphone, and can determine the environmental scene by using the existing algorithm, which is not described here.

Further, referring to fig. 3, the number of the air conduction microphones 330 is more than two, so that the sound receiving effect is better, and active noise reduction can be realized. As shown in fig. 3, the number of air conduction microphones 330 is two. Two air conduction microphones 330 are spaced apart from an inner space at a first end of the first mounting case 310.

Fig. 10 is a front view of a user wearing an externally worn earphone. Fig. 11 is a right side view of fig. 10. Referring to fig. 10 and 11, the middle portion of the first mounting case 310 is configured to fit the cheek of the user and lie beside the tragus 15 when worn by the user, and the second end of the first mounting case 310 extends obliquely rearward from top to bottom such that the second end of the first mounting case 310 covers the concha chamber 14 of the user when worn by the user. The second end of the first mounting case 310 has a sound outlet hole 311 communicating with the air conduction speaker 320 near a side wall of the concha chamber 14. That is, during the course of the second end of the first mounting shell 310 extending in the negative direction of the Z-axis, the second end of the first mounting shell 310 extends in the negative direction of the X-axis at the same time, and the first end of the first mounting shell 310 is connected to the ear hook 200 and is positioned at the upper auricle 17 of the user's ear when worn. The second end of the first mounting shell 310 extends downwardly and rearwardly such that the sound emitting member 300 extends from the upper root 17 of the user to cover the concha cavity 14 of the user (see fig. 11). Because the second end of the first installation shell 310 covers the concha cavity 14, when the sound outlet hole 311 is formed in the side wall of the first installation shell 310, which is close to the concha cavity 14, please also combine fig. 5, most of the sound emitted by the air conduction speaker 320 enters the concha cavity 14 along the direction S through the sound outlet hole 311 by air propagation, thereby avoiding sound leakage and having better privacy.

In fig. 11, the concha chamber 14 is covered by a second end of the first mounting housing 310, shown in phantom. The top of the ear hook 200 is held by the user's ear and scalp to form a fixing point Q, and the end of the ear hook 200 is bent to catch the upper auricle 17 of the user to form a further fixing point P, so that the ear hook 200 has two fixing points and can be stably disposed at the user's ear.

Wherein the middle portion of the first mounting case 310 is configured to fit the cheek of the user when worn by the user, thereby applying a supporting force F to the outer earphone to fit the cheek ₃ (see fig. 10) so that the external earphone can be stably worn on the head of the user. Specifically, the first mounting case 310 is attached to the cheek of the user at a position B (see fig. 1), so that the second end of the first mounting case 310 extends downward and rearward to cover the concha chamber 14 of the user.

Optionally, the sound outlet 311 is configured to face the concha cavity 14 of the user when the user wears the device, so that sound emitted by the air conduction speaker 320 is guaranteed to be transmitted through the air through the sound outlet 311 and basically enter the concha cavity 14, sound leakage is prevented, and privacy is good.

In this embodiment, referring to fig. 12, the connection line between two ends of the ear hook 200 refers to the connection line between the centers of the end surfaces of the two ends of the ear hook 200, and the inclined extension plane of the second end of the first mounting shell 310 refers to the side plane of the second end of the first mounting shell 310 with the sound outlet hole 311. The included angle O between the connecting line between the two ends of the ear hook 200 and the inclined extension plane of the second end of the first installation shell 310 is 5-60 degrees, so that the reasonable inclined angle of the second end of the first installation shell 310 is ensured, and under the condition that the second end of the first installation shell 310 covers the concha cavity 14, a proper interval is arranged between the second end of the first installation shell 310 and the auricle, so that sound waves emitted by the air conduction loudspeaker 320 are transmitted through the air and intensively enter the concha cavity 14 through the sound outlet 311.

Referring back to fig. 10, because an angle O is formed between the connecting line between the two ends of the ear hook 200 and the inclined extending plane of the second end of the first mounting shell 310, the sound generating component 300 extends downward to be inclined outwards in a long length, so as to avoid touching and pressing the tragus.

It will be appreciated that if the angle O between the line between the two ends of the ear hook 200 and the inclined extension plane of the second end of the first mounting shell 310 is less than 5 °, the inclination angle of the second end of the first mounting shell 310 is too small, and the interval between the second end of the first mounting shell 310 and the ear hook 200 is small, and the ear hook 200 clamps the upper auricle 17 to contact the ear, i.e. the interval between the second end of the first mounting shell 310 and the ear is small, and the second end of the first mounting shell 310 is at risk of contacting the tragus 15, resulting in pressing the ear, affecting wearing comfort. If the included angle O between the connection line between the two ends of the ear hook 200 and the inclined extension plane of the second end of the first installation case 310 is greater than 60 °, the inclination angle of the second end of the first installation case 310 is too large, the interval between the second end of the first installation case 310 and the ear is large, the second end of the first installation case 310 may be turned outwards, and cannot cover the concha cavity 14, resulting in leakage sound, and even if the concha cavity 14 is covered, sound waves are easily spread outwards due to the large interval between the second end of the first installation case 310 and the ear, and there is also a risk of leakage sound.

Optionally, the angle O between the line between the two ends of the ear hook 200 and the obliquely extending plane of the second end of the first mounting shell 310 is 5 °, 10 °, 20 °, 30 °, 40 °, 50 ° or 60 °.

Further, the included angle O between the connecting line between the two ends of the ear hook 200 and the inclined extension plane of the second end of the first mounting case 310 is 18 ° to 28 °. Through multiple tests, the included angle O accords with ergonomics no matter how the ear size and the geometric shape are different, and meets the wearing comfort and privacy requirements of human ear data of more than 95% of samples.

Optionally, the angle O between the line between the two ends of the ear hook 200 and the obliquely extending plane of the second end of the first mounting shell 310 is 18 °, 20 °, 22 °, 24 °, 26 ° or 28 °.

In one embodiment, referring to fig. 1 and 11, the first mounting shell 310 is positioned to fit the cheek of the user at a distance of 1mm to 3mm from the tragus 15 when worn by the user. That is, the distance from the position B to the tragus 15 in fig. 1 is 1mm to 3mm, and the ear pressure caused by too close distance is avoided, and the fitting force dispersion caused by too far distance is avoided, so that the wearing stability is reduced.

Referring to fig. 13, the sound outlet hole 311 is located on a side wall of the first mounting shell 310 near the concha cavity 14, instead of being located on a periphery of the first mounting shell 310, and a distance C between the sound outlet hole 311 and an edge of the first mounting shell 310 is 1 mm-10 mm, so that when the air conduction speaker 320 propagates through the sound outlet hole 311 through the sound of air propagation, the sound is prevented from being disturbed by the peripheral air flow of the first mounting shell 310, which affects the sound receiving effect of the ear, or is easy to diffuse outwards, resulting in poor privacy.

As shown in fig. 13, both sides of the sound hole 311 are spaced apart from both side edges of the first mounting case 310 by a distance C.

Alternatively, the distance C has a value of 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 5mm, 8mm or 10mm.

Specifically, if the distance C from the sound outlet 311 to the edge of the first mounting case 310 is less than 1mm, a small amount of sound waves are easily spread out along the edge of the first mounting case 310 through the sound outlet 311, affecting privacy, and the edge air flow of the first mounting case 310 is unstable, the density and speed of air are unstable, the sound waves penetrate into the concha cavity 14 through the air at the edge of the first mounting case 310, and the sound quality is deteriorated.

Specifically, if the distance C between the sound outlet hole 311 and the edge of the first mounting shell 310 is greater than 10mm, the second end of the first mounting shell 310 is oversized, the weight is large, and the first housing with oversized volume is not suitable for wearing, and covers substantially the entire auricle, so that the ear can be covered easily, and wearing comfort is affected.

In one embodiment, referring to fig. 13, in the projection of the ear hook 200 and the sound generating component 300 on the inclined extension plane of the second end of the first mounting shell 310, the maximum interval D between the ear hook 200 and the sound generating component 300 is 5 mm-20 mm, so that the ear hook 200 and the sound generating component 300 are matched, and the upper auricle 17 of the user is hung and clamped, so that the wearing is convenient. Also, the maximum spacing D between the ear hook 200 and the sound emitting member 300 defines a rearward extension angle of the second end of the first mounting shell 310 such that the second end of the first mounting shell 310 extends at this rearward extension angle to cover the concha chamber 14.

Alternatively, the maximum spacing D between the ear hook 200 and the sound generating component 300 has a value of 5mm, 6mm, 8mm, 10mm, 15mm or 20mm.

It will be appreciated that if the maximum spacing D between the ear hook 200 and the sound emitting member 300 is too great, it results in the second end of the first mounting shell 310 extending rearwardly over the earlobe 11, rather than the concha cavity 14. If the maximum spacing D between the ear hook 200 and the sound emitting member 300 is too small, it results in the second end of the first mounting shell 310 extending rearward to cover the helix 12, rather than the concha cavity 14.

Referring to fig. 13 and 14, in the projection of the ear hook 200 and the sound emitting component 300 on the inclined extension plane of the second end of the first mounting shell 310, the distance E between the two ends of the first mounting shell 310 may be selected to be 10mm to 40mm, the distance F between the second end of the first mounting shell 310 and the end of the second wire housing 210 away from the first wire housing 110 may be selected to be 10mm to 35mm, and the distance G between the sound emitting hole 311 and the first end of the first mounting shell 310 may be selected to be 5mm to 30mm.

Wherein a distance E between the two ends of the first mounting shell 310 defines a length dimension of the first mounting shell 310 in the oblique extension direction such that the second end of the first mounting shell 310 is capable of substantially covering the concha chamber 14.

Alternatively, the distance E between both ends of the first mounting case 310 may have a value of 10mm, 20mm, 25mm, 30mm, or 40mm.

It will be appreciated that if the distance E between the two ends of the first mounting shell 310 is too large, the second end of the first mounting shell 310 extends too long, resulting in a larger volume and a larger mass of the sound generating component 300, and a reduced wearing comfort, and the second end of the first mounting shell 310 has too large mass without corresponding supporting points, resulting in unstable center of gravity and reduced wearing stability. If the distance E between the two ends of the first mounting shell 310 is too small, this results in an insufficient extension of the second end of the first mounting shell 310, covering the tragus 15 instead of the concha chamber 14.

Similarly, the distance F between the second end of the first mounting case 310 and the end of the second wire housing 210 remote from the first wire housing 110 defines the length dimension of the first mounting case 310 in the oblique extension direction, so that the second end of the first mounting case 310 can substantially cover the concha cavity 14, which is not described in detail herein.

Alternatively, the distance F has a value of 10mm, 15mm, 20mm, 30mm or 35mm.

In addition, the difference between the distance E and the distance F can define the length dimension of the first end of the first mounting shell 310, so as to ensure that the middle portion of the first mounting shell 310 can fit the cheek of the user and be located beside the tragus 15.

Wherein, the distance G of the sound outlet hole 311 from the first end of the first mounting case 310 defines a position of the sound outlet hole 311 in the inclined extending direction such that the sound outlet hole 311 is exactly aligned with the concha cavity 14.

Alternatively, the distance G of the sound outlet hole 311 from the first end of the first mounting case 310 has a value of 5mm, 10mm, 15mm, 20mm, 25mm, or 30mm.

It will be appreciated that if the distance G of the sound outlet 311 from the first end of the first mounting shell 310 is too great, this results in the sound outlet 311 being aligned with the antitragus 16, rather than the concha cavity 14, and a small amount of sound waves will be conducted to the outer periphery of the first mounting shell 310. If the distance G of the sound outlet 311 from the first end of the first mounting shell 310 is too small, the sound outlet 311 is aligned with the tragus 15, and there is also a risk that a small amount of sound waves will be conducted to the outer periphery of the first mounting shell 310.

In still another embodiment of the present invention, referring to fig. 15, the sound outlet 311 is a crescent hole, and a connecting line of two ends of the crescent hole is perpendicular to an oblique extending direction of the second end of the first mounting shell 310, and the crescent hole is bent toward the second end of the first mounting shell 310.

In still another embodiment of the present invention, referring to fig. 16, the sound outlet 311 is a bar-shaped hole, and the extending direction of the bar-shaped hole is consistent with the inclined extending direction of the second end of the first mounting case 310.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
