Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

A. Overview

For explanatory purposes, the general anatomical terms coronal and sagittal for the human body are used in this application. As shown in FIG. 1, the coronal plane 3 is a virtual plane that divides the human body into anterior and posterior portions, which are positioned immediately adjacent to and in front of the ears. The sagittal plane 4 is a virtual plane dividing the human body into left and right symmetrical parts.

Since the smart audio device 10 is worn on the head, the smart device 20 and the glasses for augmented reality 30 are worn on the head of the user, and thus the coronal plane 3 and the sagittal plane 4 of the smart device 10, the smart device 20 and the glasses for augmented reality 30 are the same as those of the user.

Other directional terms, such as "front", "rear", "upper" and "lower", are also intended as shown in FIG. 1.

The term "circumferential" is not circumferential in the mathematical sense, but is generally in a direction around a person's head.

In the present application, low frequency sound refers to sound having a frequency between 20Hz and 500Hz, mid frequency sound refers to sound having a frequency between 500Hz and 2kHz, and high frequency sound refers to sound having a frequency between 2kHz and 16 kHz.

B. Detailed description of the preferred embodiments

Fig. 2 schematically shows the entirety of the head-mounted intelligent sound device 10 according to the present invention. As shown in fig. 2, the head-mounted smart audio device 10 includes a plurality of audio devices 2, and the audio devices 2 are arranged at intervals in the circumferential direction. For example, the sound 2 includes a side front sound 100 and a side rear sound 200 provided at intervals in the circumferential direction. Side front audio 100 is located in front of coronal plane 3 of head mounted smart audio device 10, and side rear audio 200 is located behind coronal plane 3 of head mounted smart audio device 10.

When ordinary two-channel sounds (e.g., two headphones) are used, the user can only perceive sounds emanating from a flat area within the range between the two sounds. However, the inventor found that, since the plurality of speakers 2 of the head-mounted smart audio device 10 of the present application are arranged at intervals in the circumferential direction, particularly, the plurality of speakers 2 include a front side speaker 100 located in front of the head (for example, in front of the ears) and a rear side speaker 200 located behind the head (for example, behind the ears), the front side speaker 100 takes charge of the sounds transmitted from the front and part of the front side and the left and right sides, and the rear side speaker 200 takes charge of the sounds transmitted from the rear and part of the rear side and the left and right sides, so that the user can feel the sounds transmitted from a circular area centered on the user after wearing the head-mounted smart audio device 10 having such a structure, and the auditory sense of presence of the user can be very real. Especially for the movie & TV or the recreation that MR/VR loaded, the utility model discloses a wear intelligent sound device 10 can transmit the sound that comes from a plurality of directions to can show the sound field effect of movie & TV or recreation more well, greatly improve user's sense of hearing.

As shown in fig. 2, side front sound 100 includes a plurality of first sub-sounds 101 provided on both sides of sagittal plane 4 of head-mounted smart audio device 10. According to this arrangement, the user can correspond the first sub-sounds 101 to themselves and ears, thereby obtaining a better auditory sensation. For the MR device, these first sub-sounds 101 are not in-ear or ear-covering, but outside and close to the ear, in order to be able to hear the real sound of the surrounding environment, whereby a plurality of first sub-sounds 101 arranged symmetrically with respect to the sagittal plane 4 is particularly suitable for the MR device. Preferably, the plurality of first sub-sounds 101 are symmetrically arranged with respect to the sagittal plane 4. In other words, the number of first sub-sounds 101 on both sides of the sagittal plane 4 is equal. For example, the first sub-sounds 101 are two in number and symmetrically arranged on both sides of the sagittal plane 4. In this way, the loudness of the sound heard by the two ears of the user is equalized, thereby contributing to further improving the auditory sensation of the user.

In a preferred embodiment, the sound outlet 102 of the side front sound 100 is directed downward (as shown in fig. 9). In this way, when the user wears the smart audio device 10, not only the side front sound 100 can be brought close to the ear, but also the sound output hole 102 of the side front sound 100 faces downward toward the ear 150, so that the user hears a greater sound loudness of the side front sound 100, which contributes to further improvement of the user's hearing feeling.

In one embodiment, the side front tones 100 are arranged so as to be circumferentially displaceable. Thus, the user can adjust the position of the side front sound 100 according to his/her preference or head size, which contributes to further improving the user's hearing feeling. In addition, for different users, since the head sizes and shapes of different users are different, each user can adjust the position of the front audio 100 according to the needs of the user, thereby expanding the application range of the head-mounted intelligent audio device 10.

In a preferred embodiment, lateral front speaker 100 is arranged parallel to sagittal plane 4. It should be understood that the term "parallel" is not to be construed in a mathematical sense, but rather is to be construed as generally parallel, e.g., there may be no more than a 30 degree angle between the two, and even a small arc of the side front 100 may be possible. The inventors have found that most people do not have perfectly round heads and have a small arc in the part from the face to the ears. To this end, arranging the lateral anterior sound 100 parallel to the sagittal plane 4 allows the lateral anterior sound 100 to be as close to the head or ear as possible to enhance the user's auditory perception.

Fig. 6 to 8 and fig. 10 schematically show the internal structure of the front side speaker 100 according to the present invention. Fig. 9 is an exploded view of the side front sound 100. As shown in fig. 6, 7, 8 and 9, the side front sound 100 includes a carrier plate 110 and a cover plate 111 snapped on the carrier plate 110. The carrier plate 110 comprises a carrier region 112 and a free region 113 adjacent to the carrier region 112, a raised annular carrier stage 160 is arranged in the carrier region 112, and a loudspeaker 114 is arranged on the carrier stage 160. The loudspeaker 114, the carrier stage 160 and the carrier region 112 of the carrier plate 110 enclose a closed first sound chamber 115. The cover plate 111 and the free area 113 of the carrier plate 110 enclose a second sound cavity 116. The volume of the first acoustic chamber 115 is smaller than the volume of the second acoustic chamber 116. It should be understood that the ring-shaped carrier 160 may be in the shape of a circular ring, or may be in the shape of any other ring, such as an elliptical ring, a rectangular ring, etc., as long as the shape of the ring can match the shape of the speaker 114.

According to the structure of the front side sound box 100, the front side sound box 100 includes the first cavity 115 and the second cavity 116, which are sealed and separated from each other. In this case, the sound emitting hole 102 of the side front sound 100 is disposed on the bearing region 112 of the carrier plate 110 and directly communicates with the first sound chamber 115. Since the speaker 114 is a part of the first sound chamber 115, the sound coming out from the sound outlet hole 102 is relatively loud, which helps to improve the auditory sensation of the user.

In another embodiment, a dust screen is attached to the sound outlet hole 102. The dust screen can prevent external contaminants such as dust from entering the front side sound box 100, and can reduce or increase the loudness of high frequency sound in the first sound cavity 115 by increasing or decreasing the mesh number of the dust screen, so as to help improve the auditory sensation of the user.

The inventor also finds that by providing the second sound cavity 116, the front side sound 100 can emit a low sound with more abundant content, so that the user can feel that the sound emitted by the front side sound 100 is deep, heavy and rich, and the auditory perception of the user is improved. In particular, the volume of the first cavity 115 is smaller than the volume of the second cavity 116, so that the bass effect of the front side sound 100 is better. In a preferred embodiment, the volume ratio of the first cavity 115 to the second cavity 116 is between 1:8 and 1:30, taking into account the product form factor, the speaker type, and the bass effect of the front side sound 100; more preferably, the volume ratio is 1: 16. For example, the volume of the first sound cavity 115 is 94mm³The volume of the second sound cavity 116 is 1680mm³. In this configuration, not only can the bass effect from the side front sound 100 be ensured to be good, but also the size of the first cavity 115 is such that it facilitates the selection of an appropriate speaker 114 and makes it possible to easily fit the speaker 114 to the carrier plate 110, thereby reducing the difficulty of manufacturing the side front sound 100.

As shown in fig. 6 and 7, the bearing region 112 divides the free region 113 into a first sub-region 117 and a second sub-region 118, the first sub-region 117 being further from the coronal plane 3 than the second sub-region 118. The cover plate 111 and the first sub-area 117 enclose a first sub-sound cavity 119, and the cover plate 111 and the second sub-area 118 enclose a second sub-sound cavity 120. Thus, the second sound cavity 116 includes a first sub sound cavity 119 and a second sub sound cavity 120, and the first sub sound cavity 119 and the second sub sound cavity 120 are penetrated through a gap 121 between the cover plate 111 and the speaker 114, and the first sound cavity 115 is located between the first sub sound cavity 119 and the second sub sound cavity 120. The inventor finds that by configuring the second sound cavity 116 as two sub-sound cavities, the space of the product can be fully utilized to ensure that the volume of the back cavity 116 is as large as possible, thereby making the sound effect of the front side sound 100 better. In addition, since the first sub-area 117 and the second sub-area 118 are spaced between the edge of the carrier area 112 and the carrier plate 110, the installation space for the speaker 114 is larger, so that the installation of the speaker 114 is more convenient, and the difficulty in manufacturing the side front sound 100 is further reduced.

In a preferred embodiment, the first sub-cavity 119 is distal from the coronal plane 3, the second sub-cavity 120 is proximal to the coronal plane 3, and the volume of the second sub-cavity 120 is less than the volume of the first sub-cavity 119. For example, the volume ratio of the second sub-sound cavity 120 to the first sub-sound cavity 119 is between 1:10 and 1: 16. The inventor finds that the structure not only satisfies that the loudspeaker 114 is against the ear, but also fully utilizes the space in the length direction of the product to make the volume of the second sub-sound cavity 116 larger, and in addition, the second sub-sound cavity 120 is formed as an effective complement to the first sub-sound cavity 119, so that the sound effect of the side front sound 100 is better. This configuration satisfies the acoustic effect requirements, shape requirements and ergonomic requirements of the side front sound 100 as a whole.

In a preferred embodiment, sound absorbing wool 122 is provided on the inner surface of the cover plate 111. In this way, the sound absorbing cotton 122 is actually placed on the inner surface of the second sound cavity 116 (including the first sub-sound cavity 119 and the second sub-sound cavity 120), which the inventors found is helpful to further enhance the bass effect of the side front sound 100 and eliminate the reflected sound pollution, thereby further improving the auditory sensation of the user. In one embodiment, the material of the sound absorbing cotton 122 may be porous microfiber glass wool, which is not described herein.

As also shown in fig. 8, the second sound chamber 116 is configured with a pressure relief hole 123 communicating with the outside. For example, the pressure relief holes 123 are on the carrier plate 110. The pressure relief hole 123 can balance the air pressure in the second sound cavity 116 with the air pressure of the external environment to prevent the sound effect of the front audio 100 from being degraded. Preferably, a ventilation film is attached to the pressure relief hole 123 to prevent dust from blocking the pressure relief hole 123.

Returning to fig. 2, side rear audio set 200 includes a plurality of second sub-audio sets 201 provided on both sides of sagittal plane 4 of head-mounted smart audio set 10. Preferably, the plurality of second sub-sounds 201 are symmetrically arranged with respect to the sagittal plane 4. In other words, the number of second sub-sounds 201 on both sides of the sagittal plane 4 is equal. For example, the second sub-sounds 201 are two in number and symmetrically arranged on both sides of the sagittal plane 4. Thus, the loudness of the sound coming from behind is equal, which contributes to further improving the auditory sensation of the user.

Preferably, the height of the side rear sound 200 is lower than the height of the side front sound 100. In a preferred embodiment, the height difference D1 between the side rear sound box 200 and the side front sound box 100 is greater than or equal to 5mm and less than or equal to 10mm, as shown in fig. 5. The inventor finds that, by adopting the arrangement mode, the lateral rear sound box 200 not only helps to create the sound effect in the front-rear direction, but also can create the sound effect in the vertical direction, so that the user can feel the sound coming from the whole spherical area with the lateral rear sound box as the center, the telepresence is more real, and the auditory sensation of the user is further improved.

As also shown in FIG. 2, the side rear audio set 200 is disposed at an acute angle α with the sagittal plane 4. for example, the acute angle α may be greater than 10 degrees and less than or equal to 30 degrees. thus, the side rear audio set 200 fits substantially on the head of a person, which not only improves the sound effect of the side rear audio set 200, but also prevents the head-mounted smart audio set 10 from falling off the head, improving wearing safety.

More preferably, the side rear sound box 200 is arranged to be displaceable in the circumferential direction. Similar to the side front sound 100, the side rear sound 200 arranged in this way can facilitate the user to adjust the position of the side rear sound 200 and expand the adaptation range of the head-mounted smart sound apparatus 10.

The specific structure of the side rear audio 200 is similar to that of the side front audio 100, except for the compliance changes in size and shape to facilitate fitting of the side rear audio 200 and to improve the sound effect of the head-mounted smart audio device 10. For example, the sound outlet hole of the lateral rear speaker 200 is directed downward; the lateral rear sound box 200 also includes a first sound cavity and a second sound cavity similar to the lateral front sound box 100, and the volume ratio of the first sound cavity to the second sound cavity can be 1: 13; the second sound cavity of the lateral rear sound box 200 also includes a first sub-sound cavity and a second sub-sound cavity, and the volume ratio of the first sub-sound cavity to the second sub-sound cavity may be, for example, 1:10 to 1: 14.

In a preferred embodiment, as shown in fig. 2, head mounted smart audio device 10 further includes front audio 300, front audio 300 being in front of side front audio 100 and in sagittal plane 4. Front audio 300 is directly in front of head mounted smart audio device 10 as a whole. By providing the front sound 300, the sound heard by the user can be further enriched to further improve the auditory sensation of the user.

In a preferred embodiment, the height of the front pitch 300 is higher than the height of the side front pitch 100. In a specific embodiment, the height difference D2 between the front sound 300 and the side front sound 100 is greater than or equal to 10mm and less than or equal to 20mm, as shown in fig. 5. This helps to further enrich the sound effect in the vertical direction, thereby further improving the user's hearing experience.

In another embodiment, the sound outlet hole 301 of the front sound 300 is directed upward. This also helps to enrich the vertical sound effect, further improving the user's hearing experience.

In a preferred embodiment, the front sound 300 emits sound at a lower frequency than the front side sound 100 and the rear side sound 200. For example, the frequency of the sound emitted from the front sound 300 is 50Hz to 500Hz, the frequency of the sound emitted from the side front sound 100 is 100Hz to 16KHz, and the frequency of the sound emitted from the side rear sound 200 is 100Hz to 16 KHz. More preferably, the front sound 300 is a bass sound. Like this, just preceding sound 300 as independent bass stereo set can build the lasting bass of whole space atmosphere for the audio of wearing intelligent audio equipment 10 has the telepresence more, and user's sense of hearing is better.

In one particular embodiment, front audio front 300 includes only one woofer and a protective case that houses the speaker. The inventor finds that the front sound 300 with the structure is simple in structure and good in sound effect, and contributes to reducing the manufacturing difficulty and cost of the head-mounted intelligent device 20 as a whole.
