Description

Technical Field

[0001] The utility model relates to the technical field of audio equipment, in particular to an OWS earphone. Background Art

[0002] With the development of the electronics industry, electronic products such as smart phones and tablet computers have been widely used in people's daily lives. As an important accessory of the above electronic products, Bluetooth headsets are becoming more and more popular.

[0003] Traditional in-ear headphones need to be inserted into the ears, so wearing them for a long time can easily cause swelling and discomfort in the ears, ear canal inflammation, and even irreversible damage to the hearing. Open-ear headphones, as a new type of Bluetooth headphones, are becoming more and more popular among consumers because of their open and non-in-ear features and will not hurt the ears when worn for a long time.

[0004] In the related art, because the open-type earphones are not inserted into the user's ears and are far away from the user's ear canal, the low frequencies will leak and the high frequencies will be attenuated too much, which will affect the sound effects. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides an OWS earphone that is conducive to improving sound quality.

[0006] According to some embodiments of the utility model, the OWS headset includes: an ear shell; a speaker, which is arranged in the ear shell; a vibrator, which is arranged in the ear shell and is parallel to and spaced apart from the speaker, and the vibrator is used to generate low-frequency vibrations within a preset range; wherein the intensity of the low-frequency vibrations generated by the vibrator within the preset range is defined as N1, and the intensity of the low-frequency vibrations generated by the speaker within the preset range is defined as N2, satisfying: N1 is greater than N2.

Since the OWS earphone of the present invention has a vibrator added, and the vibrator can generate low-frequency vibrations within a preset range, the lowest resonant frequency of the speaker itself does not need to be very low. In other words, the lowest resonant frequency of the speaker itself can be higher than the maximum value of the preset range. In this way, the problem of poor treble effect of the speaker caused by the need to make the lowest resonant frequency of the speaker itself very low can be improved. Specifically, for the speaker, its lowest resonant frequency does not need to be very low, so the high-frequency bandwidth of the speaker can be made wider accordingly, thereby increasing the acoustic frequency band of the entire OWS earphone.

[0010] According to some embodiments of the present invention, the lowest resonance frequency of the speaker is greater than the maximum value of the preset range.

[0011] According to some embodiments of the present invention, the minimum distance between the speaker and the vibrator is greater than or equal to 5 mm.

[0012] According to some embodiments of the utility model, the ear shell is further provided with a sound outlet hole, and the speaker is arranged toward the sound outlet hole, wherein there are multiple sound outlet holes, and the multiple sound outlet holes are arranged at intervals to form a fan-shaped structure.

[0013] According to some embodiments of the present invention, the first ends of the multiple sound holes point to the same area, the width of the sound holes gradually increases along the direction from the first end to the second end, and the second end of the sound hole is opposite to the first end of the sound hole.

[0014] According to some embodiments of the present invention, the ear shell includes a first panel and a second panel that are spaced apart and arranged opposite to each other, and the first panel is provided with a sound outlet hole;

[0015] The vibrator is fixed to the first panel, the diaphragm of the vibrator faces the first panel and is spaced apart from the first panel, and a vibration damping member is arranged between the vibrator and the second panel.

[0016] According to some embodiments of the present invention, a positioning groove is provided on the inner wall of the first panel, and the vibrator is provided with a positioning portion penetrating into the positioning groove.

[0017] According to some embodiments of the present invention, the first panel has a thinner region and a thicker region, the thickness of the thicker region is greater than the thickness of the thinner region, and the vibrator is fixed to the thicker region.

[0018] According to some embodiments of the present invention, the vibrator is in indirect or direct contact with the concha, and the vibration generated by the vibrator can be transmitted to the concha.

[0019] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] like Figure 1 As shown, the utility model provides an OWS headset, wherein the OWS headset refers to an open wearable headset, which adopts an open structure design and does not need to be inserted into the ear when used, ensuring the comfort of the user for a long time wearing.

[0035] It should be noted that OWS headphones can be configured with call noise reduction function and / or artificial intelligence noise reduction function, and can also be configured with stereo surround and other functions.

[0036] like Figure 2 As shown, the OWS earphone includes an ear shell 100 , a speaker 200 and a vibrator 300 .

[0037] The ear shell 100 defines a sound outlet 110 .

[0038] Specifically, the ear shell 100 is a hollow structure with an inner cavity, and a sound outlet 110 communicating with the inner cavity is provided on one side of the ear shell 100. The inner cavity of the ear shell 100 is used for placing components, and the ear shell 100 can protect the components placed in its inner cavity.

[0039] The speaker 200 is disposed in the inner cavity of the ear shell 100 , and the speaker 200 is disposed toward the sound outlet 110 .

[0040] Specifically, the speaker 200 is fixed in the auricle 100 , and the sound-producing portion of the speaker 200 is disposed toward the sound-emitting hole 110 , so that the sound emitted by the speaker 200 can be transmitted outward through the sound-emitting hole 110 .

[0041] It should be noted that the sound-producing part of the speaker 200 refers to the diaphragm of the speaker 200, and the diaphragm of the speaker 200 is arranged toward the sound outlet 110 of the ear shell 100. The speaker 200 can adopt a circular or non-circular structure, including a square, racetrack, circular or elliptical structure.

[0042] Furthermore, the speaker 200 may be a full-range speaker that can generate vibrations with a frequency of 20 Hz to 20,000 Hz.

[0043] It should be noted that the frequency range of sound perceived by the human ear is 20Hz to 20000Hz. We divide audible sound into three parts and determine the low, medium and high frequency bands, namely: low frequency band (20Hz to 160Hz), medium frequency band (160Hz to 2500Hz), and high frequency band (2500Hz to 20000Hz).

[0044] The vibrator 300 is disposed in the ear shell 100 and is arranged parallel to and spaced from the speaker 200 .

[0045] Specifically, the vibrator 300 is fixed in the inner cavity of the ear shell 100 and is arranged in parallel with the speaker 200. The vibrator 300 can also generate vibration when working. In addition, the vibrator 300 is separated from the speaker 200, and the vibrator 300 and the speaker 200 will not be in direct contact when working. In this way, the risk of mutual influence between the two when vibrating can be reduced.

[0046] Combination Figure 2 and Figure 4 Furthermore, the vibrator 300 also has a diaphragm, and the diaphragm 310 of the vibrator 300 and the diaphragm on the speaker 200 face the same direction. Of course, in other embodiments, there may be a small angle deviation between the directions of the diaphragm 310 of the vibrator and the diaphragm of the speaker 200. The thickness of the diaphragm 310 of the vibrator is less than 0.2 mm (inclusive), and the material of the diaphragm can be SUS stainless steel (such as SUS301 / 304, etc.), silicone or PU (polyurethane), etc.

[0047] Optionally, the vibrator 300 may be an eccentric wheel vibrator or a pulse vibrator, etc.

[0048] The vibrator 300 is used to generate low-frequency vibrations within a preset range.

[0049] Specifically, the preset range is within the low frequency band, and when the vibrator 300 is working, the diaphragm 310 of the vibrator 300 can generate vibrations with a frequency within the preset range.

[0050] Further, the intensity of the low-frequency vibration generated by the vibrator 300 within the preset range is defined as N1, and the intensity of the low-frequency vibration generated by the speaker 200 within the preset range is defined as N2, satisfying: N1 is greater than N2. In other words, the intensity of the vibration generated by the vibrator 300 within the preset range is higher than the intensity of the vibration generated by the speaker 200 within the preset range.

[0051] The value of N1 minus N2 is in the range of 2dB to 12dB.

[0052] It is understandable that in the OWS earphone of the present invention, by adding the vibrator 300 to generate low-frequency vibration within a preset range and making N1 greater than N2, the bass effect of the OWS earphone can be enhanced and the problem of more low-frequency leakage in traditional OWS earphones can be improved.

[0053] It should be noted that the speaker 200 of this solution can be the same speaker as the traditional OWS headset. In addition, by adding a vibrator 300, the bass effect of the OWS headset is better compared to the solution of using a single speaker in the traditional OWS headset.

[0054] Specifically in this embodiment, the preset range is 30Hz-80Hz, so that the entire OWS headset can achieve an ultra-low frequency response, which can further improve the sound effect of the OWS headset.

[0055] It should be noted that the turning on and off of the vibrator 300 can be set to be controllable, that is, a physical or touch-type function key can be set to control the turning on and off of the vibrator 300.

[0056] In addition, it should be noted that in the OWS headset of the present invention, the vibration generated by the speaker within the preset range can be filtered through the circuit to reduce energy loss. In other words, when the speaker is working, the vibration actually generated by the speaker 200 can include all the mid-frequency bands, part or all of the high-frequency bands, and part of the low-frequency bands, and the low-frequency bands within the preset range are filtered.

[0057] It should be further explained that, since the OWS earphone of the present invention adds a vibrator 300, and the vibrator 300 can generate low-frequency vibrations within a preset range, the lowest resonance frequency of the speaker 200 itself does not need to be very low. In other words, the lowest resonance frequency of the speaker 200 itself can be higher than the maximum value of the preset range. In this way, the problem of poor treble effect of the speaker 200 due to the need to make the lowest resonance frequency of the speaker 200 itself very low can be improved. Specifically, for the speaker 200, its lowest resonance frequency does not need to be very low, so the high-frequency bandwidth of the speaker 200 can be made larger accordingly, thereby increasing the acoustic frequency band of the entire OWS earphone.

[0058] It is worth understanding that in the field of acoustics, due to the law of energy conservation, if the lowest resonant frequency of the speaker 200 is low, the speaker 200 will lose frequency responses in other frequency bands, for example, resulting in insufficient high-frequency bandwidth. If the lowest resonant frequency of the speaker 200 is increased, the high-frequency loss of the speaker 200 can be reduced, and the high-frequency acoustic effect of the speaker 200 can be improved.

[0059] In some embodiments, the lowest resonant frequency of the speaker 200 is greater than the maximum value of the preset range. Specifically, the lowest resonant frequency of the speaker 200 can be set between 150 Hz and 300 Hz.

[0060] In some embodiments, the minimum distance between the speaker 200 and the vibrator 300 is greater than or equal to 5 mm. In this way, the mutual influence caused by vibration between the two during operation can be minimized. Specifically, the minimum distance between the speaker 200 and the vibrator 300 can be any value between 5 mm and 10 mm. For example, the minimum distance between the speaker 200 and the vibrator 300 can be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm.

[0061] Specifically, the speaker 200 and the vibrator 300 are spaced apart along the length direction of the concha 100 , and the minimum distance between the speaker 200 and the vibrator 300 in the length direction of the concha 100 is greater than or equal to 5 mm.

[0062] Furthermore, the speaker 200 and the vibrator 300 are arranged as centrally as possible in the width direction of the ear shell 100, so that the vibrations generated by the speaker 200 and the vibrator 300 can be transmitted more evenly.

[0063] like Figure 2 As shown, in some embodiments, there are multiple sound outlet holes 110. It is understandable that by setting the number of sound outlet holes 110 to be multiple, the sound outlet area can be increased, thereby increasing the air permeability and reducing the attenuation of the audio generated by the speaker 200.

[0064] Specifically, the plurality of sound outlet holes 110 are arranged at intervals to form a fan-shaped structure.

[0065] Furthermore, the first ends of the plurality of sound holes 110 point to the same area, the width of the sound holes 110 gradually increases from the first end to the second end, and the second end of the sound holes 110 is opposite to the first end of the sound holes 110. In this way, the area of ​​the sound holes 110 can be increased as much as possible in the limited space of the ear shell 100, thereby increasing the air permeability and reducing the attenuation of the audio generated by the speaker 200.

[0066] Specifically, the shape of a single sound outlet hole 110 may be a triangle, a cone, or a fan.

[0067] It should be noted that, in other embodiments, the shape of the sound outlet hole 110 may also be other shapes. For example, the shape of a single sound outlet hole 110 may also be a trapezoid or a prism.

[0068] Furthermore, in some embodiments, a tuning net 500 is provided at the sound outlet 110 , and the tuning net 500 can play the role of dust prevention and tuning.

[0069] like Figure 2 As shown, it can be understood that the vibrator 300 is in contact with the concha 100 indirectly or directly, and the vibration generated by the vibrator 300 can be transmitted to the concha 100.

[0070] In this way, when a user wears the OWS headset of the present invention, the vibration generated by the vibrator 300 can be transmitted to the user through the ear shell 100, so that the user can feel the vibration, which can help the user relieve tension and fatigue.

[0071] It should be noted that the vibration intensity of the vibrator 300 can be adjusted, so that the user can adjust the vibration intensity of the vibrator 300 according to needs to obtain a comfortable experience.

[0072] Combination Figure 2 and Figure 3 In some embodiments, the ear shell 100 includes a first panel 101 and a second panel 102 that are spaced apart and opposite to each other, and the sound outlet 110 is opened in the first panel 101; it can be understood that when the user wears the OWS headset of the present invention, the first panel 101 faces the user's ear and the second panel 102 faces away from the user's ear.

[0073] Furthermore, the vibrator 300 is fixed to the first panel 101 , the diaphragm 310 of the vibrator 300 faces the first panel 101 and is spaced apart from the first panel 101 , and a vibration damper 400 is disposed between the vibrator 300 and the second panel 102 .

[0074] It can be understood that, during the vibration of the vibrator 300, since the diaphragm 310 of the vibrator 300 is separated from the first panel 101, the first panel 101 will not hinder the vibration of the diaphragm 310 of the vibrator 300. In addition, a vibration damping member 400 is provided between the vibrator 300 and the second panel 102, which can reduce the risk of resonance between the vibrator 300 and the ear shell 100.

[0075] The vibration-damping component 400 may be vibration-damping cotton or vibration-damping rubber.

[0076] Furthermore, a positioning groove 1011 is provided on the inner wall of the first panel 101, and the vibrator 300 is provided with a positioning portion 320 penetrating the positioning groove 1011. In this way, the positioning accuracy of the first panel 101 and the vibrator 300 can be improved.

[0077] In addition, adhesive is provided in the positioning groove 1011, and the adhesive can fix the vibrator 300 to the first panel 101. In addition, the vibrator 300 is fixed to the first panel 101, and when the user wears the OWS headset of the present invention, the first panel 101 faces the user's ear, so that the vibration generated by the vibrator 300 can be transmitted to the first panel 101 and then to the user, providing a massage effect to the user.

[0078] Furthermore, the first panel 101 has a thinner region and a thicker region, the thickness of the thicker region is greater than the thickness of the thinner region, and the vibrator 300 is fixed to the thicker region. In other words, the vibrator 300 is fixed to the thicker position of the first panel 101, so that after the vibrator 300 transmits vibration to the first panel 101, the risk of vibration damage to the first panel 101 can be reduced, and the risk of resonance can also be reduced.

[0079] In the OWS earphone of the present invention, by adding a vibrator 300 to generate low-frequency vibrations within a preset range, and making N1 greater than N2, the bass effect of the OWS earphone can be enhanced, the problem of more low-frequency leakage of the traditional OWS earphone can be improved, and the sound effect can be improved. Since the OWS earphone of the present invention adds a vibrator 300, and the vibrator 300 can generate low-frequency vibrations within a preset range, the lowest resonance frequency of the speaker 200 itself does not need to be very low. In other words, the lowest resonance frequency of the speaker 200 itself can be higher than the maximum value of the preset range. In this way, the problem of poor treble effect of the speaker 200 caused by the need to make the lowest resonance frequency of the speaker 200 itself very low can be improved. Specifically, for the speaker 200, its lowest resonance frequency does not need to be very low, so the high-frequency bandwidth of the speaker 200 can be made wider accordingly, thereby increasing the acoustic frequency band of the entire OWS earphone.
