TECHNICAL FIELD
[0001] The present application relates to the technical field of wireless earphones, in particular to an earphone main body and an open wireless earphone. BACKGROUND
[0002] The so-called "OWS" is an earphone form extended from "TWS". Its origin is Bose Sports Open Bluetooth earphone published by Bose in 2021, which is characterized in that its loudspeaker is suspended on the user's ear and does not enter the ear canal. Therefore, it solves the discomfort caused by the invasion of the ear sleeve into the ear canal and the corresponding occurrence of the ear blockage problem of the general in-ear earphone. In the outdoor sports use scenario, the ear blockage problem is more prominent because the ear blockage makes the runner unable to hear various warning sound information on the road, which may cause serious physical injury. The demand for solving the ear blockage problem is increasingly valued with the popularization of TWS wireless earphones, and various follow-up products are like mushrooms after rain. Their forms include the architecture like Bose Sports Open and a "earring type" configuration originated from domestic BBK. The main difference between these products is that one is the positioning mechanism: how to fix the loudspeaker and the circuit compartment on the user's ear. The second is the sound energy radiation method, how the sound emitted by the loudspeaker is transmitted to the ear canal. Since the loudspeaker of OWS is open radiation, that is, the sound transmission does not pass through the guide such as the sound nozzle, ear sleeve, etc. of the in-ear earphone into the ear canal. Because it does not contact the ear canal at all, this design greatly improves the wearing comfort. And keeping the ear canal open, avoiding the annoying ear blockage effect, also maintaining the environmental situational awareness of the wearer.
[0003] Although the above-mentioned earphone type has many advantages, it also has some defects. Because of the lack of positioning provided by the ear sleeve, the position of the sound emitting port relative to the ear canal is not fixed, and the sound energy radiation is not controlled, resulting in low sound quality and excessive leakage volume. The problem of excessive leakage volume hurts the privacy of the user and forms a disturbance to the people around. And this highly variable characteristic of sound energy radiation also forms an obstacle to the realization of active noise reduction on such products. Therefore, there is an urgent need for an open wireless earphone that can accurately position the earphone main body and avoid excessive leakage volume. CONTENT OF THE UTILITY MODEL

[0030] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.
[0031] In the description of this application, the terms “center,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0032] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection" and "joining" should be interpreted broadly, for example, they can be fixed connections, detachable connections, mating connections or integral connections; those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0033] Open-back wireless earbuds can be used with electronic devices such as mobile phones, laptops, and watches to handle audio services such as media and calls, as well as other data services. For example, audio services can include playing music, recordings, audio from video files, background music in games, and call alerts; in call scenarios such as phone calls, WeChat voice messages, audio calls, video calls, games, and voice assistants, they can play the other party's voice data or collect the user's voice data and send it to the other party.
[0034] Figure 1 This diagram illustrates a human auricle structure in the prior art, such as... Figure 1As shown, the size of human ears varies greatly, and the vertical distance d from the junction of the outer ear and the skull (reference point one) to the ear hole (reference point two) also varies greatly among individuals. Figure 2 As shown, the size of human ears varies greatly, and the vertical distance d from the junction of the outer ear and the skull (reference point one) to the ear hole (reference point two) also varies greatly among individuals. Figure 2 The hook-shaped part of the ear hook is a flexible structure, but its flexible structure cannot produce enough plasticity to absorb this height difference. Therefore, the relative position of the speaker sound outlet of the OWS (Open Wireless Stereo) and the ear canal outlet also varies from person to person, and cannot be aligned. The earring earphone also has similar problems, because the width of each person's earlobe varies, Figure 3 As shown, the size of human ears varies greatly, and the vertical distance d from the junction of the outer ear and the skull (reference point one) to the ear hole (reference point two) also varies greatly among individuals. Figure 3 The design of the earring OWS also cannot absorb this inter-personal difference, and cannot stably align the sound outlet of the OWS with the ear canal outlet of different wearers. The positioning mechanism in the above-mentioned ear hook and earring earphones cannot align the earphone body with the ear canal inlet, thus causing the problem of sound leakage and quality degradation. If the sound radiation port of the OWS system cannot absorb the difference in ear size among different wearers, it will not be able to stably align with the ear canal outlet, resulting in a significant difference in actual experience sound quality among different wearers, and the leakage amount will also increase, because the best use point of the earphone is only one position, i.e., the alignment with the ear canal outlet.
[0035] Figure 4 As shown, the size of human ears varies greatly, and the vertical distance d from the junction of the outer ear and the skull (reference point one) to the ear hole (reference point two) also varies greatly among individuals. Figure 5 As shown, the size of human ears varies greatly, and the vertical distance d from the junction of the outer ear and the skull (reference point one) to the ear hole (reference point two) also varies greatly among individuals. Figure 6 As shown, the size of human ears varies greatly, and the vertical distance d from the junction of the outer ear and the skull (reference point one) to the ear hole (reference point two) also varies greatly among individuals.
[0036] As shown, the size of human ears varies greatly, and the vertical distance d from the junction of the outer ear and the skull (reference point one) to the ear hole (reference point two) also varies greatly among individuals. Figure 4 As shown, the size of human ears varies greatly, and the vertical distance d from the junction of the outer ear and the skull (reference point one) to the ear hole (reference point two) also varies greatly among individuals. Figure 5 As shown, the size of human ears varies greatly, and the vertical distance d from the junction of the outer ear and the skull (reference point one) to the ear hole (reference point two) also varies greatly among individuals. Figure 6 Among these configurations, the in-ear type can provide the best sound quality and privacy, but the sense of intrusion during wearing is very high. The second type, the semi-in-ear type, eliminates the design of the silicone sleeve, reducing the sense of intrusion, but in order to maintain sound quality, the mechanism is often more deeply inserted into the ear canal, and the comfort problem cannot be solved. In fact, the rise of OWS products is due to the fact that the above two types of sound radiation mechanisms cannot provide long-term and comfortable wearing. The third type, the flat earplug type, does not touch the ear canal at all, and there is no comfort problem during long-term wearing, but the radiation port is directly opposite the concha cavity during wearing, and the sound emitted first undergoes complex reflection before partially entering the ear canal, so the sound quality is poor and has been eliminated by the market very early.
[0037] In addition, there is an earphone in the market, Figure 7 Another earphone in the prior art is shown in the schematic diagram, as shown in the figure, Figure 7 It extends to the ear canal through the silica gel earplug, but does not touch the ear canal, although this scheme avoids the problem of direct contact with the ear canal, but needs to be directly contacted with the ear canal through the silica gel earplug to fix the earphone, this scheme has the problem of direct contact with the ear canal, which cannot provide long-term wearing comfort to the user.
[0038] In view of the above problems, the present application provides an earphone body, which is used to form positioning with the tragus, the antitragus and the inner wall of the concha cavity of the wearer, and aligns the sound radiation port with the ear canal, but does not directly contact with the ear canal and the ear canal. The earphone body can be used for open wireless earphone, which can be ear hanging type, ear ring type or neck hanging type earphone, etc.
[0039] Figure 8 A schematic diagram of an earphone body structure provided by an embodiment of the present application is shown. Figure 9 A schematic diagram of an earphone body size provided by an embodiment of the present application is shown. Figure 10 A schematic diagram of an earphone body wearing provided by an embodiment of the present application is shown. Figure 11 A schematic diagram of an earphone body wearing from another angle provided by an embodiment of the present application is shown. Figure 12 A schematic diagram of an earphone body wearing cross section provided by an embodiment of the present application is shown.
[0040] As Figure 8 An earphone body 100 provided by an embodiment of the present application is shown, which includes a shell 101, a sound radiation port 102 and an electro-acoustic module.
[0041] The shell 101 includes a front shell 1011 and a rear shell 1012, specifically, in combination with Figure 9 (a), the diameter of the shell 101 is 15mm-18mm, in combination with Figure 8 and Figure 10 The rear shell 1012 is supported by the inner wall of the tragus 201 and the antitragus 202 of the wearer, and the front shell 1011 is supported by the inner wall of the concha cavity 203, back to Figure 8 The front shell 1011 has a protruding part 1013, in combination with Figure 9 (b) and Figure 11 The angle between the plane at the top of the protruding part 1013 of the shell and the diameter of the earphone shell 101 is 22°-26°, so that the top of the protruding part 1013 extends to the ear canal opening, and covers the ear canal opening, and the contour of the protruding part 1013 leaves a gap between the ear canal opening and the ear canal 204, so that the protruding part 1013 does not touch the ear canal opening and the ear canal 204. Specifically, continue to refer toFigure 11 The concha 203 provides space for the housing 101, and at the same time provides a support point for the front shell 1011 of the housing 101 through the inner wall of the concha 203 thereof, with reference to Figure 10 The inner walls of the tragus 201 and the antitragus 202 provide a support point for the position of the rear shell 1012 of the housing 101.
[0042] Returning to Figure 8 The sound radiation port 102 is arranged at the top end of the protruding part 1013 of the front shell 1011, in combination with Figure 12 The sound radiation port 102 is aligned with the ear canal opening, but does not touch the ear canal opening and the ear canal 204.
[0043] The electro-acoustic module can be arranged inside the housing 101, which can include but is not limited to microphone elements, Bluetooth modules, control mainboards and other parts, so as to enable signal conversion and transmission, complete OWS wireless communication and play specific sounds and other functions.
[0044] It is easy to understand that the housing 101 is designed to have a proper diameter size, i.e. 15mm-18mm, to adapt to the concha size of most wearers, in combination with the size of the housing 101, the rear shell 1012 can be supported by the inner walls of the tragus 201 and the antitragus 202, and the front shell 1011 can be supported by the inner wall of the concha 203. By designing the included angle between the plane at the top end of the protruding part 1013 of the housing and the diameter of the housing 101, i.e. 22°-26°, in combination with the tragus 201, the antitragus 202 and the concha 203, a proper support point for the housing 101 is found, so that the sound radiation port 102 arranged at the top end of the protruding part 1013 of the front shell 1011 is aligned with the ear canal opening, but does not touch the ear canal opening and the ear canal 204.
[0045] As can be seen from the present example, the housing 101 of the earphone main body 100 is positioned by the inner walls of the tragus 201, the antitragus 202 and the concha 203 of the wearer, and compared with the existing OWS, it is more stable to wear and can better absorb the vibration caused by the user's vigorous movement while maintaining the positioning. The sound radiation port 102 is arranged at a key position of the front shell 1011 of the housing 101, and is aligned with the ear canal opening, without touching the ear canal opening and the ear canal 204, and under the premise of being highly comfortable, the radiation efficiency is improved and the sound leakage is reduced, so as to improve the sound quality.
[0046] The present application provides an open wireless earphone, which comprises the above-mentioned earphone main body 100. The open wireless earphone can be an ear-hanging type, an ear-ring type or a neck-hanging type earphone, etc. Since the present open wireless earphone adopts all the technical solutions of the above-mentioned embodiments, it also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here. Figure 13Fig. 1 shows a schematic diagram of an open wireless earphone according to an embodiment of the present application.
[0047] As shown in Fig. 1, an open wireless earphone according to an embodiment of the present application comprises an earphone main body 100, a clamping part 300, and an ear hook 400. Figure 13 As shown in Fig. 1, an open wireless earphone according to an embodiment of the present application comprises an earphone main body 100, a clamping part 300, and an ear hook 400. Figure 10 As shown in Fig. 1, an open wireless earphone according to an embodiment of the present application comprises an earphone main body 100, a clamping part 300, and an ear hook 400. Figure 12 As shown in Fig. 1, an open wireless earphone according to an embodiment of the present application comprises an earphone main body 100, a clamping part 300, and an ear hook 400.
[0048] As shown in Fig. 1, an open wireless earphone according to an embodiment of the present application comprises an earphone main body 100, a clamping part 300, and an ear hook 400. Figure 1 As shown in Fig. 1, an open wireless earphone according to an embodiment of the present application comprises an earphone main body 100, a clamping part 300, and an ear hook 400. Figure 2 As shown in Fig. 1, an open wireless earphone according to an embodiment of the present application comprises an earphone main body 100, a clamping part 300, and an ear hook 400.
[0049] As shown in Fig. 1, an open wireless earphone according to an embodiment of the present application comprises an earphone main body 100, a clamping part 300, and an ear hook 400.
[0050] Figure 14 Fig. 2 shows a schematic diagram of an open wireless earphone according to an embodiment of the present application. Figure 14As can be seen from (a, b, c), the structure of the ear hook 400 made of flexible material can be adjusted to correspond to the height d of different people when the headphones are worn, so that the sound radiation port 103 of the headphone body can be aligned with the ear canal opening of different people.
[0051] In one example, the inner contours of the retaining part 300 and the inner contours of the earphone body 100 have rounded curves to facilitate a close fit to the ear.
[0052] In one example, the holding part 300 of the wireless open-back headphones includes a battery module, one end of the ear hook 400 is connected to the electroacoustic module 100 in the headphone body, and the other end of the ear hook 400 is connected to the battery module in the holding part 300. Specifically, the battery module can be disposed inside the holding part 300, and can be used to store electrical energy and deliver electrical energy to the electroacoustic module through the wires in the ear hook 400.
[0053] In one example, a partial telescopic mechanism is provided at the connection between the ear hook 400 and the headphone body 100, allowing the axial length of the ear hook 400 to freely extend or shorten. Specifically, the partial telescopic mechanism includes, but is not limited to, telescopic mechanisms using elastic rubber, spring shafts, or gear drives. For example, in a gear-driven telescopic mechanism, the gear meshes with a toothed rack. When the gear rotates, it moves linearly along the direction of the rack, thereby pushing the entire telescopic mechanism to extend outward or retract inward.
[0054] As this example demonstrates, the partial telescopic mechanism allows the ear hook 400 to adjust to the most suitable position according to the wearer's ear shape. When the headphones are not in use, the telescopic mechanism allows the ear hook 400 to retract, reducing the overall size of the headphones and making them more compact for easy carrying in a bag or travel case.
[0055] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.
[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
