Detailed Description

The following is a preferred embodiment of the present application, and it should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present application, and these improvements and modifications are also considered as the protection scope of the present application.

Before the technical solutions of the present application are introduced, the technical problems in the related art will be described in detail.

With the continuous development of electronic devices, the variety of electronic devices is increasing, and a head-mounted electronic device is just one of them. The head-mounted electronic device is a device which can be worn on the head of a user and enables the user to realize various functions through a lens. Head-mounted electronic devices typically include smart glasses, AR glasses, or VR glasses, among others. The intelligent mobile phone has an independent operating system, can install programs provided by other software service providers such as working software and game software, and can also complete functions of adding schedules, map navigation, interacting with friends, taking photos and videos, performing video call with friends and the like through voice or action control. And can realize wireless network access through a mobile communication network like other network equipment.

In order to realize the output of audio in various functions, a speaker system is usually added in the head-mounted electronic device, and the speaker is usually placed in a temple of the head-mounted electronic device, but due to the limitation of the size of the temple, the rear sound cavity structure is small, so that the low-frequency sound quality of the speaker in the head-mounted electronic device is poor, and the quality of the audio is reduced.

In the field of mobile phones, however, in electronic devices such as mobile phones, a housing is usually provided outside a speaker unit, the speaker unit is housed in the housing, and other materials are housed in the housing to form a speaker assembly to improve low-frequency performance. However, the requirement of the existing temple is usually narrow and thin, and no extra space is provided for making a loudspeaker assembly similar to that in a mobile phone, so that the size of the temple is only increased, the appearance and the comfort of the man-machine experience are influenced, and the design concept of the existing temple is also violated.

In view of this, in order to solve the above problems, the present application provides a temple of a novel structure. Referring to fig. 1 to 5, fig. 1 is a schematic perspective view of a head-mounted electronic device according to an embodiment of the present disclosure. Fig. 2 is a schematic perspective view of a part of a temple according to an embodiment of the present application. Fig. 3 is an exploded view of fig. 2. Fig. 4 is a schematic view of a mirror leg with a portion of a housing removed according to an embodiment of the present application. Fig. 5 is a schematic sectional view taken along a-a direction in fig. 2. The present embodiment provides a temple 1, the temple 1 being intended to be worn on a target object, the temple 1 including a case 10, a speaker unit 20, and a plurality of sound absorbers 30. The housing 10 has a receiving cavity 11 therein, and the housing 10 is provided with a sound outlet hole 12. The speaker unit 20 is disposed in the accommodating cavity 11, and divides the accommodating cavity 11 into a first sound cavity 111 and a second sound cavity 112, wherein the first sound cavity 111 is communicated with the sound outlet 12. A plurality of sound absorbing members 30 are disposed in the second sound cavity 112, and at least a portion of the sound absorbing members 30 contact the speaker unit 20.

The temple 1 provided in the present embodiment is mainly applied to the head-mounted electronic apparatus 2, and the main body of the head-mounted electronic apparatus 2 is worn on a target object. The head-mounted electronic device 2 includes smart glasses, a see-through type (see-through type) electronic device, and a closed type (see-closed type) electronic device. The perspective type provides Augmented Reality (AR), and the closed type provides Virtual Reality (VR). It may also be understood that the head mounted electronic device 2 comprises AR glasses or VR glasses. The target object may be the head of a user, or other objects such as a support, a model, etc. Optionally, the head-mounted electronic device 2 is used as the smart glasses and the target object is used as the head of the user for indication. Therefore, the present application can use the temples 1 to mount the lenses 4 and the frame 5 on the ears of the user for wearing.

The temple 1 provided in this embodiment includes a casing 10, and the casing 10 is mainly used to protect and mount other components inside the casing 10. And the temples 1 are mainly the case 10 in contact with the user when worn on the user's ears. As shown in fig. 2, the present embodiment is illustrated with a part of the temple 1 omitted. The housing 10 has a receiving cavity 11 for receiving various other components such as the speaker unit 20, the sound absorbing material 30, and the main board 70. Because the speaker unit 20 is disposed in the temple 1, the casing 10 may further be provided with a sound outlet hole 12 communicating with the accommodating cavity 11, so that sound emitted from the speaker unit 20 can be better transmitted to be received by the ear of the user.

Alternatively, the housing 10 provided in this embodiment is not of an integral structure, but of a split structure, that is, the housing 10 is not an integral whole, but is assembled by two sub-housings 10. For example, the housing 10 includes a first sub-housing 101 and a second sub-housing 102 connected in a split manner, the first sub-housing 101 covers the second sub-housing 102, the sound outlet 12 is disposed on the first sub-housing 101, and the first sub-housing 101 and the second sub-housing 102 enclose to form the receiving cavity 11. The casing 10 includes a first sub-casing 101 and a second sub-casing 102, and the first sub-casing 101 is used for accommodating structural members such as the speaker unit 20 and the sound absorbing member 30, and can be understood as a temple 1 support. The second sub-housing 102 is mainly used for packaging, and may be understood as a temple 1 housing. The second sub-housing 102 may be adhesively fixed to the first sub-housing 101 by an adhesive. And the first sub-housing 101 and the second sub-housing 102 together enclose to form a containing cavity 11.

In addition, since the partial structure of the housing 10 is omitted in the drawings of the present application, the end portion of the housing 10 has a hole, and the housing space can be sealed well in the complete structure of the housing 10, and foreign substances do not enter the housing space.

In addition, the present embodiment may further include a dust screen installed in the sound outlet hole 12 to prevent external dust, impurities, and the like from entering the first sound chamber 111.

The temple 1 provided in the present embodiment further includes a speaker unit 20, wherein the speaker unit 20 is mainly used to emit sound. The speaker unit 20 is disposed in the accommodating cavity 11, and the speaker unit 20 does not directly abut against the housing 10 for generating sound, but has a certain gap with the housing 10, and divides one accommodating cavity 11 into two independent sound cavities, i.e., a first sound cavity 111 and a second sound cavity 112, the first sound cavity 111 is communicated with the sound outlet hole 12, the sound of the first sound cavity 111 can be transmitted from the sound outlet hole 12, and how the sound of the second sound cavity 112 is transmitted is not limited herein. For example, the sound in the second sound chamber 112 can be transmitted to the outside by vibration of the housing 10, or a hole is formed in the housing 10 to transmit the sound.

In addition, how the speaker unit 20 separates one accommodating cavity 11 into two independent sound cavities can be realized by the speaker unit 20 itself or by matching other components with the speaker unit 20. This application will be described in detail later.

The first sound chamber 111 connected to the sound outlet 12 can be understood as a front chamber and the second sound chamber 112 as a rear chamber. The front cavity is a sound reflection area, which has the effect of sound amplification, and can improve the medium frequency, reduce the high frequency noise, reduce the high frequency section extension and improve the sound conversion efficiency. The back volume has an effect of enhancing the intensity of the sound, mainly increasing the low frequencies. But due to the small size of the temple 1, for example only 100mm 15mm 7.5 mm. The size of the rear chamber is small, resulting in poor low frequency sound effect of the temple 1.

As can be seen from the above, the low frequency performance of the speaker unit 20 can be improved by forming the speaker assembly in the related art, and then installing the speaker assembly into the cabinet. However, due to the size limitation of the temple 1, the problem cannot be solved by such a method. Therefore, in the present invention, by additionally providing a plurality of sound absorbers 30, the plurality of sound absorbers 30 are provided in the second sound chamber 112, that is, in the rear chamber. Wherein, sound absorbing member 30 is provided with a plurality of holes, so that at least part of sound can pass through these holes, and the sound absorbing effect is achieved. The sound absorbing member 30 is provided to increase the sound propagation distance, lower the resonance frequency F0 of the speaker unit 20, and improve the low-frequency sound quality and low-frequency sensitivity of the speaker unit 20. Meanwhile, the sound absorbing member 30 increases the virtual space of the second sound cavity 112, and enlarges the equivalent volume of the second sound cavity 112, so that the temple 1 can provide better low-frequency tone quality, and the low-frequency performance of the temple 1 is improved.

In addition, in this embodiment, at least a part of the sound absorbing material 30 is in contact with the speaker unit 20, and it is not necessary to provide a separate space for the speaker unit 20, so that more sound absorbing materials 30 can be installed in a limited space, the number of sound absorbing materials 30 can be increased, the size of the temple 1 can be further reduced, and the low frequency performance can be improved.

Optionally, the sound absorbing member 30 may include a plurality of types, for example, the sound absorbing member 30 includes at least one of sound absorbing cotton and sound absorbing particles. That is, the sound absorbing material 30 may be sound absorbing cotton, the sound absorbing material 30 may be sound absorbing particles, and the sound absorbing material 30 may be sound absorbing cotton and sound absorbing particles. The material of the sound-absorbing cotton is melamine, and the sound-absorbing cotton is formed by adopting a hot-pressing process. Because the sound-absorbing cotton is provided with a plurality of compact holes, the sound-absorbing effect is good, the resonance frequency F0 of the loudspeaker single body 20 can be reduced, and the low-frequency sensitivity of the loudspeaker single body 20 is improved. The sound-absorbing particles are particles with a plurality of holes on the surface, and have the same sound-absorbing principle and effect as sound-absorbing cotton. When the sound-absorbing member 30 includes sound-absorbing cotton, the sound-absorbing cotton may be bonded to the casing 10. When the sound-absorbing member 30 includes sound-absorbing particles, the sound-absorbing particles can be freely filled in the second sound chamber 112, and since the sound-absorbing particles are powdered, the user does not feel the presence of the sound-absorbing particles while wearing the temple 1 and exercising. When the sound absorbing member 30 includes sound absorbing cotton and sound absorbing particles, the sound absorbing cotton may be bonded to the casing 10, and then the sound absorbing particles may be bonded to the sound absorbing cotton.

Further optionally, the sound absorbing particles comprise Bass powder. Bass is a high polymer expansion material, is in a powder shape, has holes on the surface, and can improve the low-frequency performance of the loudspeaker monomer 20.

Optionally, the total volume of the plurality of sound absorbing members 30 is 50% to 90% of the volume of the second sound cavity 112. That is, the sound absorbing member 30 does not need to be filled completely in the second sound cavity 112, and only 50% -90% of the second sound cavity 112 needs to be filled to optimize the low frequency performance. Further optionally, the total volume of the plurality of sound absorbers 30 is 70% of the volume of the second sound cavity 112.

In addition, how the plurality of sound absorbing members 30 are installed in the second sound cavity 112 may be implemented by any means, and the present application is not limited thereto, and will be described in detail below. And in order to make the drawings clearer, the present application shows only the sound-absorbing member 30 in fig. 3 to 5, and the structure of the sound-absorbing member 30 is omitted in other drawings.

Please refer to fig. 2 and fig. 6 together, and fig. 6 is a schematic cross-sectional view of a temple according to another embodiment of the present application. In this embodiment, the casing 10 has an inner side 13, an outer side 14, and an ear hanging surface 15, where the inner side 13 is opposite to the outer side 14, and the ear hanging surface 15 is bent to connect the inner side 13 and the outer side 14;

the casing 10 further has a filling surface 16 opposite to the ear hanging surface 15, and the filling surface 16 is provided with a filling hole 17 communicated with the second sound cavity 112.

In the present embodiment, the housing 10 has a plurality of surfaces, of which the inner side 13, the outer side 14, and the ear surface 15 are used to abut against a target object. It will also be appreciated that when the temple 1 is worn on the user's ear, the inner side 13 will abut the user's side face and the outer side 14, opposite the inner side 13, will abut the user's ear. As for the ear hanging surface 15 is the surface of the temple 1 directly abutting on the ear, i.e. the lower surface. Whereas the filling surface 16 lying opposite the lower surface can be considered as the upper surface.

In this embodiment, the filling surface 16 may be provided with a filling hole 17 communicating with the second sound cavity 112. The filling holes 17 are used to fill the sound absorbing members 30 into the second sound cavity 112 through the filling holes 17, so that the sound absorbing members 30 are installed. Besides the filling function of the filling hole 17, the sound of the second sound cavity 112 can be transmitted to the outside through the filling hole 17 because the filling hole 17 is also connected with the second sound cavity 112, and the sound transmission function is realized. The filling opening 17 can thus also be regarded as a leakage opening which leaks sound, so that one filling opening 17 has two functions at the same time, combining the filling opening 17 with the leakage opening.

In addition, in the present embodiment, the filling holes 17 are formed in the filling surface 16, and as can be seen from the above description, when the temple 1 is worn on the ear of the user, the filling surface 16 is an upper surface, so that the plurality of sound absorbers 30 do not fall out of the filling holes 17, thereby improving the stability of the sound absorbers 30.

Referring to fig. 7, fig. 7 is a schematic cross-sectional view of a temple according to another embodiment of the present application. In this embodiment, the temple 1 further includes a first air-permeable spacer 40, the first air-permeable spacer 40 is provided in the filling hole 17 and connected to the casing 10, the first air-permeable spacer 40 is provided with a plurality of first through holes 41 communicating with the filling hole 17, and the diameter of the first through holes 41 is smaller than the size of the sound absorbing member 30.

In this embodiment, a first air-permeable partition 40 may be further provided. The first gas-permeable partition 40 is disposed in the filling hole 17 and connected to the housing 10, so that the filling hole 17 is isolated from the outside by the first gas-permeable partition 40. And the first air-permeable partition 40 is provided with a plurality of first through holes 41 communicating with the filling hole 17, and the diameter of the first through holes 41 is smaller than the size of the sound-absorbing member 30. The first through-hole 41 is provided so that the first ventilation spacer 40 has both the ventilation function and the isolation function. The ventilation function means that the sound of the second sound chamber 112 can still be transmitted from the first through hole 41 after the first ventilation spacer 40 is installed. The isolation function means that the aperture of the first through hole 41 is smaller than the size of the sound-absorbing member 30, so that the sound-absorbing member 30 does not fall out of the filling hole 17.

Alternatively, the first air-permeable partition 40 may be bonded to the case 10 by means of an adhesive.

Optionally, the first breathable barrier 40 comprises a dust screen.

Alternatively, when the sound-absorbing member 30 is a sound-absorbing particle, the size of the sound-absorbing member 30 is generally 0.8 to 1 mm. The size of the first through-hole 41 at this time is 0.3-0.5 mm.

In other embodiments, the sound absorbing material 30 may be filled in the case of the separate type case 10 by additionally providing the filling hole 17. For example, the speaker unit 20 may be first installed in the first sub-housing 101, then the sound absorbing members 30 are installed in the first sub-housing 101, and finally the second sub-housing 102 is bonded to the first sub-housing 101.

Referring to fig. 7 again, in the present embodiment, a surface of the first air-permeable partition 40 facing away from the second sound cavity 112 is flush with the filling surface 16.

On the basis of additionally arranging the first air-permeable partition 40, in this embodiment, the surface of the first air-permeable partition 40 on the side away from the second sound cavity 112 may be flush with the filling surface 16, that is, the outer surface of the first air-permeable partition 40 is flush with the filling surface 16, so that the upper surface of the temple 1 may be flush as a whole, and the flatness and the appearance performance of the temple 1 are improved.

Alternatively, the color of the first air-permeable partition 40 may be the same as the color of the filling face 16, so that the user cannot distinguish the first air-permeable partition 40, further improving the appearance performance of the temple 1.

Referring to fig. 7 again, in the present embodiment, the sound outlet hole 12 is disposed on the ear hanging surface 15, and the sound outlet hole 12 is disposed opposite to the filling hole 17.

In this embodiment, the sound outlet hole 12 may be provided on the ear hanging surface 15, and the filling hole 17 may be provided on the filling surface 16. Since the ear surface 15 is disposed opposite to the filling surface 16, the sound outlet hole 12 is also disposed opposite to the filling hole 17. In this way, the phase of the sound wave transmitted from the sound outlet hole 12 is opposite to the phase of the sound wave transmitted from the filling hole 17, so that the two sounds are cancelled out, the sound heard by an external user is reduced, and the silencing effect of the speaker unit 20 is improved.

Referring to fig. 8, fig. 8 is a schematic view illustrating a head-mounted electronic device with temples when the head-mounted electronic device is mounted on a target object according to an embodiment of the present disclosure. In the present embodiment, when the temple 1 is worn on the subject, the sound emitting hole 12 is close to the ear of the subject.

Since the sound emission hole 12 is provided on the ear hanging surface 15 on the lower surface, in the present embodiment, when the temple 1 is attached to the subject, the sound emission hole 12 can be brought close to the ear of the subject. Therefore, the sound outlet hole 12 is closer to the ear, the sound emitted from the sound outlet hole 12 can be better locked and received by the user, and the sound quality and the sound volume of the glasses legs 1 are improved.

Referring to fig. 9, fig. 9 is a schematic cross-sectional view of a speaker unit according to an embodiment of the present application. In this embodiment, the speaker unit 20 includes a body 21 and a second air-permeable partition 22, the body 21 is provided with a sound outlet 210 for emitting sound, at least a portion of the second air-permeable partition 22 covers the sound outlet 210, the second air-permeable partition 22 is provided with a second through hole 220, and the diameter of the second through hole 220 is smaller than the size of the sound absorbing member 30.

As can be seen from the above, at least a part of the sound-absorbing member 30 may contact the speaker unit 20. The present application provides a specific implementation, in this embodiment, the speaker unit 20 includes a body 21 and a second air-permeable partition 22. The body 21 is a component for generating sound from the speaker unit 20, and the body 21 is provided with a sound generating hole 210 for generating sound. And the second air-permeable member is used to cover the sound outlet hole 210. And the second air-permeable partition 22 is provided with second through holes 220, and the diameter of the second through holes 220 is smaller than the size of the sound-absorbing member 30.

The second air-permeable partition 22 has the same function as the first air-permeable partition 40, and also has the air-permeable function and the isolation function, and the second through hole 220 allows the sound emitted from the sound outlet 210 to be transmitted into the second sound cavity 112 through the second through hole 220. And because the aperture of the second through hole 220 is smaller than the size of the sound absorbing member 30, the sound absorbing member 30 is blocked by the second air-permeable isolating member 22 and does not contact the body 21, so that the sound outlet 210 is not blocked, and the sound quality of the speaker unit 20 is ensured.

Optionally, the second through-hole 220 has a size of 0.3-0.5 mm.

Please refer to fig. 10-11 together, fig. 10 is a partial perspective view illustrating a housing and a fixing member according to an embodiment of the present application.
