【Detailed ways】

The following will clearly and completely describe the technical solutions of the present application with reference to the accompanying drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, not all of them. Based on the implementation of the present application, other implementations obtained by persons of ordinary skill in the art without creative efforts all fall within the protection scope of the present application.

The inventor of the present application has found through long-term research that the sound-generating glasses are difficult to wear at the ear canal opening like earphones due to the structure of the glasses themselves (except for the combined form of glasses and earphones), and generally have a certain distance from the ears. In this way, it is difficult to provide users with excellent sound quality, the user's listening experience is poor, and it often causes serious sound leakage problems, causing certain noise impacts on the surroundings. In order to improve the above technical problems, the present application proposes the following embodiments.

FIG. 1 is a schematic perspective view of the three-dimensional structure of an embodiment of the glasses of the present application. As shown in FIG. 1 , the spectacles 10 described in the spectacles embodiment of the present application may include: a spectacle frame 100 , temples 200 , lenses 300 and sound emitting devices 400 .

The mirror legs 200 are connected to the mirror frame 100 . The spectacle frame 100 may be used to mount a lens 300 . There may be at least one temple 200 and lens 300 . For the case where there is one temple 200 and one lens 300, it belongs to a relatively special unilateral spectacles. For the case where there are two temples 200 and two lenses 300 , two lenses 300 can be placed on the frame 100 . The two temples 200 can be respectively connected to two sides of the mirror frame 100 . Specifically, the glasses 10 may be arranged symmetrically. That is, the picture frame 100 can be arranged symmetrically, the two lenses 300 can be symmetrically installed in the picture frame 100 , and the two temples 200 can be symmetrically connected to both sides of the picture frame 100 .

As for the connection between the mirror leg 200 and the mirror frame 100, the connection method of the two may be hinged. In the wearing state, the temples 200 are supported above the ears, and the nose pads (not shown) of the spectacle frame 100 are supported on the bridge of the nose, so that the glasses 10 can be worn on the user's head stably. Each temple 200 may include a front section and a back section. In the wearing state, the front section of the mirror leg 200 can be located between the ear and the face, that is, on one side of the ear, and the rear section of the mirror leg 200 can be located between the ear and the back of the head, that is, on the other side of the ear. Optionally, the front section may be in the shape of a straight rod, and the rear section may be inclined at a certain angle relative to the front section. The connection between the front section and the back section can be set in an arc shape, so as to facilitate the cooperation and support of the temples 200 and the ears when wearing the glasses 10 .

The sound-generating device 400 can be arranged in the mirror leg 200 for playing sound. When the user wears the glasses 10 , audio can be played through the sound generating device 400 . For example, the glasses 10 can establish a Bluetooth connection with a mobile terminal, and then play audio in the mobile terminal through the sound generating device 400, or make and receive calls. For example, a storage device (not shown) may be provided in the glasses 10 for storing files such as audio, and then the audio in the storage device may be played through the sound generating device 400 . For example, the glasses 10 may have a sound-receiving function, and the audio of a radio station may be played through the sound-generating device 400 .

Please refer to FIG. 2 . FIG. 2 is a partial cross-sectional schematic diagram of an embodiment of the spectacle temple of the present application in a wearing state. The number of the sound emitting device 400 may be at least one. At least one sound emitting device 400 is disposed in the temple 200 . For example, for the glasses 10 with two temples 200 , at least one sound emitting device 400 is disposed in at least one of the temples 200 . Optionally, at least one sound emitting device 400 may be arranged in each temple 200 . Optionally, two sound emitting devices 400 may be arranged in each temple 200 . Of course, there is no limit to the number of sound emitting devices 400 disposed in the temple 200 . The sound generating device 400 is, for example, a loudspeaker.

The exemplary structure of the mirror leg 200 is described below, and then the structural relationship between the sound emitting device 400 and the mirror leg 200 is described exemplarily.

As shown in FIG. 2 , an installation cavity 210 is opened in the temple 200 provided with the sound emitting device 400 . The installation cavity 210 is used for accommodating the sound emitting device 400 . Wherein, one installation cavity 210 can accommodate one sound-generating device 400 , and can also accommodate multiple sound-generating devices 400 . Of course, the installation cavity 210 can also accommodate components such as circuit boards and circuits corresponding to the sound-generating device 400 . Specifically, the corresponding temple 200 of the installation cavity 210 may be provided with a detachably connected installation hole (not shown) and an installation plate (not shown). The installation hole communicates with the installation cavity 210 . Mounting plates can be used to close the mounting holes. After removing the mounting plate, the sound emitting device 400 can be placed in the mounting cavity 210 through the mounting hole. For example, the mirror leg 200 can be an integral detachable structure, and the mirror leg 200 can be disassembled into at least two parts of the housing, thereby exposing the internal structure of the mirror leg 200. By combining and connecting the at least two parts of the housing to form an installation cavity 210, Furthermore, the placement of the sound-generating device 400 and the like in the installation cavity 210 can be achieved through disassembly and assembly.

As shown in FIG. 2 , in the glasses 10 , the temple 200 is provided with a sound outlet 220 . The sound-generating device 400 disposed in the mirror leg 200 can transmit sound outward through the sound-out hole 220 , so that the sound can enter the user's ear.

For the temple 200 provided with the sound outlet 220 , at least two sound outlets 220 arranged at intervals may be provided on the temple 200 . Taking one of the temples 200 of the glasses 10 as an example, the temple 200 is provided with at least two sound holes 220 arranged at intervals.

In this embodiment, the temple 200 of the glasses 10 is provided with at least two sound outlet holes 220 arranged at intervals, and the at least two sound outlet holes 220 are used to transmit the sound emitted by at least one sound emitting device 400 . In the wearing state, at least two of the sound holes 220 on the temple 200 are at the same distance from the opening of the ear canal of the corresponding ear. In this embodiment, the same distance may include that the two distances are absolutely the same, and may also include that the two distances are substantially the same. That is to say, the same distance can allow a certain range of errors. For example, if the difference between the two distances is within 2CM, it can be called the same distance. Certainly, the range of the error may also be 0-1CM, 0-3CM, 0-4CM, 0-5MM or 0-8MM, etc., and the error range is not specifically limited, and it may be other data ranges besides the above examples. In this embodiment, the ear corresponding to the temple 200 refers to the ear supporting the temple 200 .

Specifically, in this embodiment, the plane passing through the openings of the ear canals of the two ears is used as a reference plane (not shown in the figure), which is parallel to the frame 100 when the glasses 10 are worn, and is located on at least one side of the same temple 200. The vertical distance from each of the two sound outlet holes 220 to the reference plane can be set to 1-5 cm. Under the condition that the distance from the sound outlet 220 to the corresponding ear canal opening is equal, the vertical distance from the sound outlet 220 to the reference plane can be the same or different, and can be flexibly adjusted according to the setting of the temple 200, and there is no limitation here.

Further, the vertical distance from at least two of the sound outlet holes 220 of the same temple 200 to the reference plane can be set to be 2-4 cm, so that the sound transmitted by the sound outlet holes 220 corresponding to the same ear canal can be Corresponding to the ear canal to achieve a better hearing effect.

By setting at least two of the sound outlet holes 220 in the same mirror leg 200 at the same distance from the corresponding ear canal opening, the sound emitted through the two sound outlet holes 220 can achieve relatively uniform sound field superposition at the position of the ear canal opening, Furthermore, the sound quality can be effectively improved without changing the volume level, thereby improving the listening experience of the ears. At the same time, under the condition that the ears obtain the same loudness (that is, the volume obtained by the ears remains unchanged), since at least two of the sound outlet holes 220 realize sound field superposition, the loudness emitted by the sound emitting device 400 can be compared to that obtained by a single sound outlet. The loudness of the hole 220 is small when there is no sound field superposition, and the loudness of the sound radiated in other directions outside the ear canal is smaller, which can effectively reduce sound leakage and reduce the impact of noise on surrounding people.

Optionally, the temple 200 provided with the sound outlet 220 may be provided with a channel 230 , the number of the channels 230 may be the same as that of the sound outlet 220 and the positions may be corresponding, and the channel 230 may communicate with the sound outlet 220 . Further, the channel 230 communicates with the installation cavity 210 and the sound outlet 220, and is used to guide the sound played by the sound emitting device 400 in the installation cavity 210 to the corresponding sound outlet 220, so that the sound can pass through the sound outlet 220 from the temple Transmission within 200. Of course, the channel 230 may not be provided in this embodiment, and the sound outlet 220 may directly communicate with the installation cavity 210 .

In this embodiment, the channels 230 and the sound outlet holes 220 may be communicated in a one-to-one correspondence. Specifically, the channels 230 can each communicate with the installation cavity 210, so that the sound played by the sound-generating device 400 in the installation cavity 210 can be transmitted to the ear canal of the ear corresponding to the temple 200 through the channels 230 and the corresponding sound holes 220 in the wearing state. .

In some specific application examples, the channel 230 can also be set to communicate with the sound outlet 220 as a whole, or it can be set to be fixed or detachably connected to the sound emitting device 400, and it can be accommodated in the installation cavity 210 and connected to the outlet. The sound hole 220 is connected, and it can be flexibly set according to the structure of the temple 200 and the installation cavity 210, and there is no limitation here.

Optionally, as shown in FIG. 2 , at least two of the channels 230 on the same temple 200 are arranged in a converging shape in a direction close to the opening of the ear canal. Further, all the sound holes 220 may be set on the lower side of the temple 200 facing the opening of the ear canal when the temple is worn. In other words, at least two of the channels 230 point to or face the opening of the ear canal, and the sound holes 220 are provided on the side of the temple 200 closest to the opening of the ear canal when worn, so that the channels 230 can guide the sound-generating device 400 toward the opening of the ear canal. The sound is played, and the sound outlet 220 outputs the sound toward the direction closest to the opening of the ear canal, thereby facilitating the ear canal to receive the sound, which can improve the sound quality. Specifically, the channel 230 is arranged in a converging shape in the direction close to the opening of the ear canal, that is, the guiding directions of the channels 230 are all toward the corresponding ear canal opening, so that after the sound is transmitted through the sound hole 220, it can experience a short period of time. The distance, and reach the ear canal in the shortest direction of transmission, reducing the distance of sound transmission, and then the sound can be transmitted to the ear canal in a shorter time, which can reduce the spread of sound in the air.

Specifically, the number of installation cavities 210 can also be set to be no greater than the number of channels 230, and each installation cavity 210 is correspondingly communicated with at least one channel 230, that is, the installation cavities 210 can be communicated with the channels 230 respectively, or one installation cavity 210 A plurality of passages 230 are connected, which can be flexibly adjusted according to the specific structures of the mounting cavity 210 on the temple 200 , the passage 230 and the temple 200 . In some specific application scenarios, for the mirror leg 200 provided with the sound emitting device 400, the sound emitting device 400 located on the same mirror leg 200 may correspond to at least two sound outlets 220 on the mirror leg 200, and also That is, one sound-generating device 400 corresponds to one sound-emitting hole 220 , and each sound-generating device 400 transmits sound through a corresponding channel 230 and sound-emitting hole 220 . Further, in some other specific application examples, as shown in FIG. 4, FIG. 4 is a schematic structural diagram of an embodiment of a sound emitting device for glasses according to the present application. On the same temple 200, one sound generating device 400 can also correspond to two Or more than two sound outlets 220 .

Further, the distances between the sound emitting devices 400 located on the same temple 200 and the corresponding sound output holes 220 may be set to be the same. The same distance here is the same as the distance described above, and a certain range of errors can be allowed. Of course, for different positions with the same distance, the respective error ranges can be different.

Specifically, the lengths of the channels 230 corresponding to the sound outlets 220 can be set to be the same, that is, the distances from the sound emitting devices 400 to the respective sound outlets 220 are the same. Taking the same temple 200 including two sound-generating devices 400 as an example, when the two sound-generating devices 400 emit sound, the corresponding sound-emitting holes 220 can simultaneously output sound.

For the case where at least two sound outlets 220 correspond to the same sound emitting device 400 , the distances from the sound emitting device 400 to the corresponding at least two sound outlets 220 are equal.

Of course, in some specific application examples, at least two sound outlets 220 may also correspond to one or more channels 230 respectively, that is, at least two sound outlets 220 may also correspond to one or more sound emitting devices 400 respectively . For the situation that at least two sound outlet holes 220 respectively correspond to different sound emitting devices 400, the distances between the sound outlet holes 220 and the respective corresponding sound emitting devices 400 are the same; In other words, the sum of the distances from the sound outlet 220 to the corresponding plurality of sound emitting devices 400 is the same.

The distances between each sound-generating device 400 and its corresponding sound-generating hole 220 are equal, so that before the sound is transmitted from different sound-generating holes 220, the time it takes for the sound to transmit between the sound-generating hole 220 and the sound-generating device 400 is roughly the same, thereby improving the sound quality The uniformity of the sound field and the effectiveness of the superposition of the sound field.

Optionally, as shown in FIG. 2 , in the wearing state, at least two of the sound outlets 220 located on the same temple 200 are respectively located on both sides of the ear, that is, at least one of the sound outlets 220 is located on one side of the ear. At least one other sound outlet 220 is located on the other side of the ear, and the number of sound outlets 220 on both sides is the same.

For example, in the wearing state, the front section and the back section of a temple 200 are respectively located on the front and back sides of the opening of the ear canal, and the same number of at least one sound outlet 220 is respectively provided at the back section and the front section of a temple 200 . Further, the positions of the sound outlet holes 220 on both sides of the ear canal opening can be set to correspond one to one, and the distances from the corresponding two sound outlet holes 220 to the corresponding ear canal opening are the same. For example, two sound outlets 220 are provided on the same temple 200, and the two sound outlets 220 are respectively located on two sides of the ear, and the two sound outlets 220 are set at the same distance from the ear canal. For another example, four sound outlet holes 220 are set on the same temple 200, and every two sound outlet holes 220 are located on the same side of the ear, and the two sound outlet holes 220 on one side of the ear are connected to the two sound outlet holes on the other side of the ear. The holes 220 are in one-to-one correspondence, that is, the distance from the corresponding sound holes 220 on both sides of each pair of ears to the opening of the ear canal is the same. For example, the center points of the intersecting surfaces of the two sound holes 220 and the corresponding temples 200 may be at the same distance from the center point of the corresponding ear canal opening, and the distance may be a straight line distance.

By arranging at least two of the sound outlet holes 220 on the same temple 200 to be located on the front and rear sides of the ear respectively, and the number of sound outlet holes 220 on both sides is the same, effective sound field superposition can be realized at the ear canal opening, and the sound output can be reduced as much as possible. The hole 220 is superimposed on the sound field outside the opening of the ear canal, and can further reduce the sound field difference caused by the different number of sound holes 220 on both sides of the ear, affecting the sound field superposition effect, thereby further reducing sound leakage, and being located on both sides of the ear can make The sound creates a sense of space, which in turn facilitates the effect of surround sound.

Of course, in some specific application examples, at least two of the sound holes 220 located on the same temple 200 may also be set to be located on the same side of the ear and at the same distance from the opening of the ear canal of the corresponding ear in the wearing state. For example, if the front section of a mirror leg 200 is not straight but curved, two sound outlets 220 can also be provided at the front section of the temple 200 to achieve the same distance from the two sound outlets 220 to the opening of the ear canal. Of course, the sound hole 220 may not be limited to the front section or the back section of the ear canal opening when the temple 200 is worn. The specific structure may be changed according to the structural setting requirements and application requirements, and there is no limitation here.

Please refer to FIG. 3 . FIG. 3 is a schematic diagram of sound field superimposition of the glasses embodiment of the present application in a wearing state. Take two sound outlet holes 220 set on one mirror leg 200 as shown in FIG. 3 as an example. The distances from the two sound outlet holes 220 to the opening of the ear canal are the same, so that the sound is transmitted between the two sound outlet holes 220 and the opening of the ear canal. The transmission distance between them is the same, and in the case of the same transmission medium, the transmission time is also the same, so that the sounds of different sound holes 220 on the temple 200 can realize the superposition of the sound field at the position of the ear canal opening, and then when transmitting the sound of the same loudness , this setting can enable the ear to receive louder sound, and then also improve the sound leakage and the noise caused by the sound leakage when the glasses 10 play sound.

Optionally, at least two sound outlets 220 on one temple 200 may each correspond to a sound emitting device 400 , and each sound emitting device 400 may respond to the same electrical signal. When receiving an electrical signal for sound playback, the two sound-generating devices 400 in the same temple 200 that respond to the electrical signal can realize synchronous sounding. In this embodiment, at least two sound outlets 220 provided on the same temple 200 may also correspond to the same sound emitting device 400, as shown in FIG. 5, which shows the structure of another embodiment of the sound emitting device for glasses of the present application. Schematic diagram, each sound outlet 220 can also correspond to multiple sound emitting devices 400, but the sound emitting devices 400 corresponding to each sound outlet 220 can all respond to the same electrical signal, which can reduce the time difference between the two sound outlets 220 outputting sound , and then reduce the time difference between the two sound output holes 220 output sound received by the ear canal, so as to achieve a better sound field superposition effect at the position of the ear canal, and improve the sound quality heard by the user during use.

Further, in the case that the glasses 10 include two temples 200 , the sound holes 220 of the two temples 200 may be arranged symmetrically. That is to say, the sound holes 220 on the two temples 200 have the same effect on the sound field superposition formed by the two temples 200 at their corresponding two ear canal openings, so that the ears on both sides of the wearer of the glasses 10 can hear The same sound field superposition effect can be achieved, so that the wearer can hear better sound quality through the glasses 10 .

Optionally, as shown in FIG. 6 , which is a schematic structural diagram of an embodiment of the sound outlet of the glasses of the present application, the two sound outlets 220 located in the same temple 200 can be divided into two groups, which are the first hole group and the first hole group. Second hole set. The first hole group and the second hole group may each include at least one sound outlet hole 220 . That is, if there are at least two sound outlet holes 220 in the same temple 200 , then the first hole group and the second hole group may each include at least one sound outlet 220 . Further, the number of sound outlet holes 220 included in the first hole group is the same as the number of sound outlet holes 220 included in the second hole group, and there is a one-to-one correspondence. That is, any sound outlet 220 in the first hole group has a corresponding one in the second hole group. Specifically, the distances from the corresponding two sound outlet holes 220 in the first hole group and the second hole group to the corresponding ear canal openings are equal, so as to ensure that the sound output by all the sound outlet holes 220 can achieve sound field superposition at the ear canal opening. , to improve the loudness of the received sound.

Optionally, all the sound holes 220 of the glasses 10 can be arranged on one temple 200 of the glasses 10 , or can be arranged on two temples 200 of the glasses 10 . When all the sound holes 220 of the glasses 10 are disposed on the two temples 200 of the glasses 10 , the numbers of the sound holes 220 disposed on the two temples 200 may be the same or different. The distances from the sound holes 220 on the two temples 200 to their corresponding ear canal openings can be the same or different, but the distances from the sound holes 220 on each mirror leg 200 to their respective corresponding ear canal openings are the same. When the device 400 plays sound, the sound field superposition at the position of the ear canal opening corresponding to each temple 200 can be realized.

To sum up, in the same mirror leg 200, when at least two of the sound holes 220 are at the same distance from the opening of the ear canal, the two sound holes 220 can superimpose the sound field at the position of the ear canal opening, thereby improving the user's listening experience. The sound quality can be improved, and the sound leakage can be reduced while the loudness obtained by the ear remains unchanged.

The above is only the implementation of the application, and does not limit the patent scope of the application. Any equivalent structure or equivalent process conversion made by using the specification and drawings of the application, or directly or indirectly used in other related technologies fields, are all included in the scope of patent protection of this application in the same way.
