Description

Earphone main body and open wireless earphone

Technical Field

The application relates to the technical field of wireless earphones, in particular to an earphone main body and an open wireless earphone.

Background

The term "OWS" is a form of earphone that extends from "TWS". The Open Sports Bluetooth headset is characterized in that the loudspeaker of the Open Sports Bluetooth headset is suspended on the ear of a user and does not enter the auditory canal. Therefore, the problems of discomfort caused by the invasion of the earmuffs into the auditory canal and corresponding blocking of the ears of the general in-ear headphones are solved. In outdoor exercises, the problem of blocking the ears is more remarkable, and the runner cannot hear various warning sound information on the road due to the blocking of the ears, so that the body can be injured when serious. The requirement of solving the problem of ear blocking is increasingly emphasized with the popularization of TWS wireless earphones, and various following products such as spring bamboo shoots after rain. The form of the BBK is structured like Bose Sports Open, and an 'earring' form of the BBK is originated from China. One of the main differences between these products is the positioning mechanism which secures the horn and the circuit box to the user's ear. The second is the method of radiating acoustic energy, how the sound emitted by the horn is conducted to the ear canal. Since the horn of OWS is open radiating, that is, its sound transmission is not directed into the ear canal through the mouth, ear muff, etc., of an in-ear earphone. This design promotes very high wearing comfort as it does not contact the ear canal at all. And keep the opening of the auditory canal, avoid the annoying effect of blocking the ear, also maintain the environmental situation perception of the wearer.

Although the above-described earphone type has many advantages, there are also some drawbacks. Because of the lack of positioning provided by the earmuffs, the sound emitting port is not fixed relative to the ear canal, and the radiation of acoustic energy is not controlled, resulting in low sound quality and excessive leakage volume. The problem of excessive leakage of volume is that the privacy of the user is compromised, and the surrounding person is disturbed. And the highly variable nature of this acoustic energy radiation also forms an obstacle to achieving active noise reduction on such products. Therefore, there is a need for an open wireless headset that can accurately position the headset body while avoiding excessive leakage of volume.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

In the description of the present application, the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present application and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present application.

In the description of the present application, it should be noted that, unless explicitly stated and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixed, removable, or contradictory or integral, as will be understood by those of ordinary skill in the art in view of the detailed description of the present application.

The open wireless earphone can be used with electronic devices such as mobile phones, notebook computers and watches, and can process audio services such as media, conversation and the like of the electronic devices, and other data services. For example, the audio service may include playing music, recording, sound in a video file, background music in a game, incoming call prompting voice, etc. for the user, or playing voice data of the opposite terminal for the user or collecting voice data of the user and transmitting the voice data to the opposite terminal in a call service scene such as telephone, weChat voice message, audio call, video call, game, voice assistant, etc.

Fig. 1 shows a schematic diagram of a human auricle structure in the prior art, in which, as shown in fig. 1, human ears are different in size, and there is a great difference in the size of a vertical distance d from a junction (reference point one) of an outer ear and a skull to an ear opening (reference point two). Fig. 2 shows a schematic diagram of an ear-hanging earphone of the prior art. Currently, with reference to fig. 2, the hook portion of the ear hook is an elastic structure, but the elastic structure cannot generate enough plasticity to absorb the height difference. Therefore, the relative positions of the horn mouth and the ear canal mouth of the OWS (Open Wireless Stereo, open wireless earphone) also vary from person to person and cannot be aligned. While earring headphones have similar problems in that the width of each individual's earlobe varies, fig. 3 shows a schematic diagram of the prior art of wearing earring headphones, and referring to fig. 3, the design of earring OWS cannot absorb such variation in average of persons, and the sound-producing mouth of OWS cannot be stably aligned with the ear canal mouth of different wearers. The positioning mechanism in the above-mentioned ear-hanging type and earring type earphone cannot align the earphone body to the entrance of the auditory canal, so that the problems of sound quality degradation and sound leakage often occur. If the acoustic radiation ports of the OWS system cannot absorb the difference of the ear sizes of different wearers, the acoustic radiation ports cannot be stably aligned to the ear ports, so that the actual experience tone quality of different wearers has a significant fall, and meanwhile, the leakage quantity is improved, because the optimal use point of the earphone is aligned to the position of the ear port.

FIG. 4 shows a schematic representation of an in-ear earphone of the prior art, FIG. 5 shows a schematic representation of a half-in-ear earphone of the prior art, and FIG. 6 shows a schematic representation of a flat-head earplug earphone of the prior art;

As for the acoustic radiation method of the in-ear earphone, there have been three configurations mainly in the past, i.e., in-ear type (represented by Airpod Pro as shown in fig. 4), semi-in-ear type (represented by Airpod I, II as shown in fig. 5), and flat-head earplug type (represented by fig. 6). Of these several configurations, in-ear provides the best sound quality and privacy, but the invasive feel of wear is very high. The second half-in-ear type has the advantages that the design of a silica gel sleeve is eliminated, the invasion feeling is reduced, but in order to keep the tone quality, the mechanism of the second half-in-ear type is more deep into the auditory canal, and the comfort problem still cannot be solved. In fact, the rise of the OWS products, which arises because the two acoustic radiating mechanism versions as described above do not provide long-term, comfortable wear. The third type of flat-head earplug, although not touching the auditory canal at all and having no comfort problem for long-term wearing, however, the radiation port is opposite to the concha cavity when wearing, and the emitted sound enters the auditory canal partially after complex reflection, so the sound quality is bad and is eliminated by the market for a long time.

In addition, there is an in-ear earphone on the market, fig. 7 is a schematic diagram of another in-ear earphone in the prior art, as shown in fig. 7, which extends to the ear canal through a silica gel earplug, but does not touch the ear canal, although the scheme avoids the problem of direct contact with the ear canal, the earphone needs to be in direct contact with the ear canal opening through the silica gel earplug to enable the earphone to be positioned and fixed, and the scheme has the problem of direct contact with the ear canal opening, and can not provide comfort for users to wear for a long time.

In view of the above, the present application provides an earphone body for positioning with the tragus, antitragus and inner wall of the concha cavity of a wearer, aligning an acoustic radiation port with an ear canal port, but not in direct contact with the ear canal port and the ear canal. The earphone body can be used for an open wireless earphone, and the open wireless earphone can be an ear-hanging earphone, an earring earphone or a neck-hanging earphone.

Fig. 9 shows a schematic diagram of a size of an earphone body provided by an embodiment of the present application, fig. 10 shows a schematic diagram of wearing an earphone body provided by an embodiment of the present application, fig. 11 shows a schematic diagram of wearing an earphone body at another angle provided by an embodiment of the present application, and fig. 12 shows a schematic diagram of wearing a cross-section of an earphone body provided by an embodiment of the present application.

As shown in fig. 8, an embodiment of the present application provides an earphone body 100 including a housing 101, an acoustic radiation port 102, and an electroacoustic module.

The housing 101 comprises a front housing 1011 and a rear housing 1012, specifically, with reference to fig. 9 (a), the diameter of the housing 101 is 15mm-18mm, with reference to fig. 8 and 10, the rear housing 1012 is supported by the tragus 201 and the inner wall of the antitragus 202 of the wearer, the front housing 1011 is supported by the inner wall of the concha cavity 203, and back to fig. 8, the front housing 1011 has a convex part 1013, with reference to fig. 9 (b) and 11, the angle between the plane of the top end of the convex part 1013 of the housing and the diameter of the earphone housing 101 is 22 ° -26 °, so that the top end of the convex part 1013 extends to the ear canal opening and covers the ear canal opening, and a gap is left between the outline of the convex part 1013 and the ear canal opening and the ear canal 204, so that the convex part 1013 does not touch the ear canal opening and the ear canal 204. Specifically, with continued reference to fig. 11, the concha cavity 203 provides space for the housing 101 while the interior walls of the concha cavity 203 provide support points for the front shell 1011 of the housing 101, and with reference to fig. 10, the interior walls of the tragus 201 and antitragus 202 provide support points for the back shell 1012 of the housing 101.

Returning to fig. 8, the acoustic port 102 is disposed at the top of the boss 1013 of the front housing 1011, and in conjunction with fig. 12, the acoustic port 102 is aligned with the ear canal opening, but does not touch the ear canal opening and the ear canal 204.

The electroacoustic module may be disposed inside the casing 101, and may include, but is not limited to, a microphone element, a bluetooth module, a control motherboard, etc., so that the electroacoustic module can perform signal conversion and transmission, and perform the functions of OWS wireless communication, playing specific sound, etc.

It will be readily appreciated that the shell 101 is sized to accommodate the size of the concha cavity of most wearers, i.e. 15mm-18mm, and that in combination with the size of the shell 101, the rear shell 1012 may be supported by the inner walls of the tragus 201 and antitragus 202 of the wearer, and the front shell 1011 may be supported by the inner walls of the concha cavity 203. By designing the angle between the plane of the top of the protruding part 1013 of the housing and the diameter of the earphone housing 101, i.e. 22 ° -26 °, and combining the tragus 201, the antitragus 202 and the concha 203, a suitable support point is found for the housing 101 such that the sound radiation opening 102 provided at the top of the protruding part 1013 of the front housing 1011 is aligned with the ear canal opening, but does not touch the ear canal opening and the ear canal 204.

As can be seen from this example, the housing 101 of the earphone body 100 is positioned by the inner walls of the tragus 201, antitragus 202 and concha cavity 203 of the wearer, and is more stable to wear and more able to absorb shock caused by the intense movement of the user while remaining positioned, compared to the existing OWS. An acoustic radiation port 102 is arranged at a key position of the front shell 1011 of the casing 101 and is aligned to the ear canal port, so that the radiation efficiency is improved and the acoustic leakage is reduced on the premise of not touching the ear canal port and the ear canal 204 at all and being highly comfortable, thereby improving the sound quality.

The embodiment of the application provides an open wireless earphone, which comprises the earphone main body 100. The open type wireless earphone can be an ear-hanging type, an earring type or a neck-hanging type earphone, etc. Because the open wireless earphone adopts all the technical schemes of the above embodiments, the open wireless earphone has all the beneficial effects brought by the technical schemes of the above embodiments, and will not be described in detail herein. Fig. 13 shows a schematic diagram of an open wireless headset according to an embodiment of the present application.

As shown in fig. 13, an embodiment of the present application provides an open wireless earphone including the earphone body 100, where the open wireless earphone further includes a holding portion 300 and an ear hook 400. The ear hook 400 is composed of a flexible material and a conductive wire, and in particular, the conductive wire is wrapped by the flexible material, and both ends of the ear hook 400 are respectively connected with the earphone body 100 and the clamping part 300. Specifically, when the open wireless earphone is worn, the ear hook 400 is put on the junction of the auricle and the skull of the wearer, and the shape of the ear hook 400 can be adjusted to enable the holding part 300 to be held and fixed behind the ear of the wearer, and the earphone body 100 is supported by the tragus 201, the antitragus 202 and the inner wall of the concha 203 of the wearer, so that the sound radiation port 102 is aligned with the ear canal port of the wearer, as shown in fig. 10 and 12.

Because of the great difference of the body structures of each person, in the content shown in fig. 1, the joint of the external ear and the skull of the person is set as a first reference point, the ear opening is set as a second reference point, the distance from the first reference point to the second reference point is marked as d, the d values of each person in real life are different, as shown in fig. 2, for the main-stream configuration ear-hanging earphone in the prior art, the hook-shaped part of the ear-hanging earphone is an elastic structure and cannot generate enough plasticity to absorb the height difference, so that when different wearers use the earphone with the structure, the relative positions of the horn sounding opening and the ear canal opening can be different from person to person, and the situation of misalignment can occur.

It is easy to understand that the flexible material ear hook 400 can maintain the adjusted shape after being deformed by the external force, and does not recover the original shape when no external force is applied, and when the open wireless earphone is worn, the ear hook 400 is put on the junction of the auricle and the skull, and the retaining portion 300 can be retained and fixed behind the ear of the wearer by adjusting the outline shape of the ear hook, and the earphone body 100 is fixed on the tragus 201, the antitragus 202 and the inner wall of the concha cavity 203 of the wearer, and the sound radiation port 102 is opposite to the ear canal port, so that the wearer can listen to the sound played by the earphone body 100.

Fig. 14 is a schematic view of an ear-hook positioning adjustment mode of an open wireless earphone according to an embodiment of the present application. As can be seen from fig. 14 (a, b, c), the ear hook 400 of the open wireless earphone provided in this example can be configured to be adjusted to the height of d of different persons when the earphone is worn by changing the form of the ear hook 400 of the flexible material, so that the acoustic radiation port 103 of the earphone body can be aligned with the ear canal port of different persons.

In one example, the inside profile of the catch 300 and the inside profile of the earphone body 100 have rounded curvature to facilitate fitting the pinna.

In one example, the holding portion 300 of the wireless open earphone includes a battery module, one end of the ear hook 400 is connected to the electroacoustic module of the earphone main body 100, and the other end of the ear hook 400 is connected to the battery module of the holding portion 300, specifically, the battery module may be disposed inside the holding portion 300 and may be used to store electric energy and transmit the electric energy to the electroacoustic module through a wire in the ear hook 400.

In one example, a local telescopic mechanism is provided at the connection between the ear hook 400 and the earphone body 100, so that the axial length of the ear hook 400 can be freely extended or shortened. In particular, the partial retraction mechanism includes, but is not limited to, a retractable mechanism using elastomeric glue, a spring shaft, or a gear drive. For example, in a gear driven telescopic mechanism, in particular, the gear is matched with a toothed rack, when the gear rotates, the gear moves linearly along the direction of the rack, so that the whole telescopic mechanism is pushed to extend outwards or retract inwards.

As can be seen from this example, the local telescopic mechanism allows the ear hook 400 to be adjusted to the most appropriate position according to the shape of the wearer's ear. When the earphone is not used, the telescopic mechanism can enable the ear hook 400 to be contracted, the overall size of the earphone is reduced, the earphone is more compact, and the earphone is convenient to carry in a bag or a travel box.

In the description of the present specification, a particular feature, structure, material, or characteristic may be combined in any suitable manner in one or more embodiments or examples.

It is finally noted that the above embodiments are only for illustrating the technical solution of the present application and are not intended to limit the same, and although the present application has been described in detail with reference to the above embodiments, it should be understood by those skilled in the art that the technical solution described in the above embodiments may be modified or some technical features may be equivalently replaced, and these modifications or replacements do not deviate the essence of the corresponding technical solution from the scope of the technical solution of the embodiments of the present application.
