Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the specification. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of glasses according to the present application. The eyeglasses 100 described in the present embodiment may include a frame 10 and two temples 20 (e.g., divided into a first temple 21 and a second temple 22), and each temple 20 may be provided with two dipole speakers 30. The two dipole loudspeakers 30 located at the same temple 20 are at different distances from the ear canal mouths of the respective ears and are arranged such that there is a delay in the electrical signals between each other to enable a beam formation in the direction towards the ear canal mouths for acoustic wave superposition.

In the eyeglasses 100, on the one hand, there is a time delay between the electrical signals of the two dipole speakers 30 of the same temple 20, so that the sound waves emitted by the two dipole speakers 30 can be superimposed in a first direction towards the mouth of the ear canal of the respective ear and in a second direction away from the mouth of the ear canal of the respective ear, and cancel each other out in a direction perpendicular to the first direction and the second direction. On the other hand, the out-of-phase sound waves emitted by the dipole loudspeaker 30 from opposite sides of its sound emitting element 32 can also be superimposed in a first direction towards the ear canal orifice of the respective ear and in a second direction away from the ear canal orifice of the respective ear, with cancellation occurring in a direction perpendicular to the first and second directions. Therefore, in the first direction towards the ear canal mouth of the corresponding ear, multiple sound waves are superposed to form a wave beam in a fixed direction, which is beneficial to improving the audio effect; in the direction perpendicular to the first direction and the second direction, multiple sound waves are mutually offset, so that sound leakage is reduced, and the privacy requirement of a user is met. In addition, the dipole speaker 30 is advantageous in improving the sound effect of low frequencies compared to a general speaker.

In some embodiments, three dipole speakers 30 may be provided on each temple 20, the three dipole speakers 30 located on the same temple 20 being at different distances from the ear canal orifice of the respective ear, and two of them being delayed with respect to the electrical signal of the other to enable superposition of sound waves in a direction towards the ear canal orifice. In fact, the provision of two dipole speakers 30 per temple 20 already meets the general needs of the user and contributes to the cost of the product, as well as to the bulk of the temple 20, so that the overall appearance of the eyeglasses 100 is more dexterous.

The same number of dipole speakers 30 is provided on both temples 20, which is advantageous for enhancing the audio effect. In some embodiments, the number of dipole speakers 30 provided on the two temples 20 may also be different. For example, two dipole speakers 30 are provided on the first temple 21, and the second temple 22 is provided with no dipole speakers 30, one dipole speaker 30, or three or more dipole speakers 30.

The present application does not limit the specific number of dipole speakers 30 on each temple 20, and at least two dipole speakers 30 are disposed on at least one temple 20, and those skilled in the art can freely select the specific number of dipole speakers 30 on each temple 20 according to actual requirements.

With continued reference to fig. 1, the specific structure of the eyeglasses 100 will be described.

Specifically, one end of the temple 20 is connected to the frame 10, and the two temples 20 are respectively connected to opposite sides of the frame 10, forming a basic frame of the glasses 100. In the worn state, the two temples 20 may be supported on the two ears of the wearer, respectively. Of course, the eyeglasses 100 may further comprise lenses, which may be embedded in the frame 10, or may be integrally formed with the frame 10. In some embodiments, the eyeglasses 100 may also include only one temple 20, i.e., a more specific single-sided eyeglass. The number of the temples 20 is not limited in this application, and those skilled in the art can select the number according to actual needs.

The temple 20 may have a cavity (not shown) formed therein and the two dipole speakers 30 may be disposed within the cavity of the temple 20. For example, as shown in fig. 1, a portion of the temple 20 located at the front side of the face in a wearing state may be provided with a boss 201, the boss 201 may be formed with a cavity, and the two dipole speakers 30 may be provided in the boss 201. On same mirror leg 20, the quantity that holds the chamber can be the same with dipole loudspeaker 30's quantity, holds between the chamber independent each other moreover, and each other is not communicated, and then makes two dipole loudspeakers 30 reduce the interference to each other, promotes tone quality. Of course, on the same temple, the number of the cavities may also be one, at least two dipole speakers 30 are accommodated in the same cavity, and the sound outlet holes (as shown in fig. 2, the front sound hole 35 and the rear sound hole 36) of the dipole speakers 30 are not communicated in the cavities.

As shown in fig. 1, the two dipole speakers 30 located at the same temple 20 are disposed along the length direction of the corresponding temple 20, and may be specifically disposed at a portion of the temple 20 where the ear faces the face in the wearing state. In some embodiments, the two dipole speakers 30 located on the same temple 20 may also be located on the portion of the temple 20 where the ear faces away from the face when worn, or one of the two dipole speakers may be located on the portion of the temple 20 where the ear faces away from the face when worn, and the other one of the two dipole speakers may be located on the portion of the temple 20 where the ear faces away from the face when worn.

Two dipole speakers 30 located in the same temple 20 are disposed at the portion of the temple 20 located at the face of the ear in the wearing state, so that the sound waves emitted from the dipole speakers 30 can be prevented from being blocked by the auricle, thereby preventing the loss of audio frequency and being beneficial to improving the effect of audio frequency.

The description "the two dipole speakers 30 located at the same temple 20 are arranged along the length direction of the corresponding temple 20" in the present embodiment may mean that the direction of the connecting line of the two dipole speakers 30 located at the same temple 20 is the same or substantially the same as the length direction of the temple 20, i.e., a certain error range is allowed, for example, an error range is-10 ° to 10 °, that is, the direction of the connecting line of the two dipole speakers 30 located at the same temple 20 may have an angle of-10 ° to 10 ° with the direction of the temple 20, and may also be regarded as "the two dipole speakers 30 located at the same temple 20 are arranged along the length direction of the corresponding temple 20".

In some embodiments, the direction of the connecting line of the two dipole speakers 30 located on the same temple 20 may also be inclined with respect to the length direction of the temple 20, for example, the direction of the connecting line of the two dipole speakers 30 located on the same temple 20 may also be inclined with respect to the length direction of the temple 20 by 30 °, or inclined with respect to the length direction of the temple 20 by 45 °.

The two dipole speakers 30 located at the same temple 20 are provided along the length direction of the corresponding temple 20 to facilitate reducing the maximum distance between the lower side and the upper side of the temple 20 in a wearing state, i.e., the maximum width of the temple 20, to facilitate improving the appearance of the glasses 100.

Next, a specific structure of the dipole loudspeaker 30 is explained, referring to fig. 2 specifically, fig. 2 is a schematic structural view of the dipole loudspeaker in the glasses shown in fig. 1.

The dipole loudspeaker 30 comprises a shell 31 and a sound generating element 32, wherein the sound generating element 32 is arranged in the shell 31 to divide the interior of the shell 31 into a front sound cavity 33 and a rear sound cavity 34; wherein, the housing 31 further defines a front sound hole 35 and a rear sound hole 36, the front sound hole 35 is connected to the front sound cavity 33, the rear sound hole 36 is connected to the rear sound cavity 34, so that the dipole loudspeaker 30 generates out-of-phase sound waves from the front sound hole and the rear sound hole of the sound generating element 32.

In some embodiments, the number of the front sound holes 35 may be multiple, for example, 2, the number of the rear sound holes 36 may also be multiple, for example, 2, and the numbers of the front sound holes 35 and the rear sound holes 36 may also be different, for example, the number of the front sound holes 35 is 1, and the number of the rear sound holes 36 is 2. The application is not limited with respect to the specific number of the front sound holes 35 and the rear sound holes 36, and those skilled in the art can select them according to actual needs.

Alternatively, in order to ensure the effect of superposition of sound waves between the two dipole speakers 30 located at the same temple 20, the distance between the front sound holes 35 of the two dipole speakers 30 located at the same temple 20 is greater than or equal to 1cm and less than or equal to 5 cm. For example, the distance between the front sound holes 35 of the two dipole speakers 30 located at the same temple 20 may be 1.0cm, 1.5cm, 2.0cm, 2.5cm, 3.0cm, 3.5cm, 4.0cm, 4.5cm, or 5.0 cm.

Referring to fig. 3 and 4 together, fig. 3 is another schematic structural diagram of the glasses shown in fig. 1, and fig. 4 is another schematic structural diagram of the glasses shown in fig. 1. The temple 20 is provided with sound holes, each dipole loudspeaker 30 corresponds to two sound holes, and each dipole loudspeaker 30 transmits sound outwards through the corresponding sound hole.

Specifically, the sound outlet holes include a first sound outlet hole 202 and a second sound outlet hole 203. Each dipole loudspeaker 30 corresponds to a first sound outlet 202 and a second sound outlet 203, wherein the first sound outlet 202 is correspondingly communicated with the front sound hole 35, for example, the first sound outlet 202 and the front sound hole 35 can be overlapped and butted. The second sound outlet 203 is correspondingly communicated with the rear sound hole 36, for example, the second sound outlet 203 and the rear sound hole 36 can be overlapped and butted. That is, two first sound outlet holes 202 and two second sound outlet holes 203 are provided on each temple 20.

In some embodiments, in the wearing state, the difference between the distances between the two dipole speakers 30 located on the same temple 20 and the ear canal opening is set to be equal to the product of the time delay and the sound velocity, so as to further promote the sound waves emitted by the two dipole speakers 30 to be superimposed in the first direction toward the ear canal opening of the corresponding ear and in the second direction away from the ear canal opening of the corresponding ear, and to be cancelled in the direction perpendicular to the first direction and the second direction, thereby better improving the audio effect and reducing the sound leakage.

The "difference between the distances between the two dipole speakers 30 located in the same temple 20 and the ear canal opening is set to be equal to the product of the time delay and the sound velocity" described in the present embodiment may mean that the difference between the distances between the two dipole speakers 30 located in the same temple 20 and the ear canal opening is set to be equal to or substantially equal to the product of the time delay and the sound velocity, that is, a certain error range is allowed, for example, an error range of-10% to 10%, that is, a difference between the distances between the two dipole speakers 30 located in the same temple 20 and the ear canal opening and the product of the time delay and the sound velocity is between-10% and 10%, and may be regarded as "the difference between the distances between the two dipole speakers 30 located in the same temple 20 and the ear canal opening is set to be equal to the product of the time delay and the sound velocity".

As shown in FIG. 1, the distance between the dipole loudspeaker 30a farther from the corresponding ear and the ear canal opening is denoted as d₁Let d denote the distance between the dipole loudspeaker 30b, which is closer to the respective ear, and the ear canal mouth₂Then, the time Δ t of the delay is:

where c represents the transmission speed of sound, and is particularly related to the transmission medium of sound, for example, when the glasses 100 are used in air, c may refer to the transmission speed of sound in air, and when the glasses 100 are used underwater, c may refer to the transmission speed of sound in water.

In some embodiments, the distance d between the dipole loudspeaker 30a, which is further from the respective ear, and the ear canal orifice₁May be a distance d between the center of the front sound hole 35 of the dipole speaker 30a and the center of the mouth of the ear canal, and a distance d between the dipole speaker 30b closer to the corresponding ear and the mouth of the ear canal₂May refer to the distance between the center of the front sound hole 35 of the dipole loudspeaker 30b and the center of the ear canal orifice.

In some embodiments, the distance d between the dipole loudspeaker 30a, which is further from the respective ear, and the ear canal orifice₁May be a distance d between the center of a line connecting the front sound hole 35 and the rear sound hole 36 of the dipole speaker 30a and the center of the mouth of the auditory canal, and between the dipole speaker 30b closer to the corresponding ear and the mouth of the auditory canal₂May refer to the distance between the center of the line connecting the front sound hole 35 and the rear sound hole 36 of the dipole loudspeaker 30b and the center of the ear canal orifice.

In some embodiments, the front sound hole 35 and the rear sound hole 36 of the dipole loudspeaker 30 are disposed opposite to each other, and the front sound hole 35 and the rear sound hole 36 may be disposed such that an extension line of the connection line passes through the ear canal mouth of the corresponding ear when the eyeglasses 100 are in the wearing state.

The description in this application that the front sound hole 35 and the rear sound hole 36 may be arranged such that the extended lines of both lines pass through the ear canal mouths of the respective ears when the eyeglasses 100 are in the worn state may mean that the front sound hole 35 and the rear sound hole 36 are arranged such that the extended lines of both lines pass through the ear canal mouths of the respective ears in the range where the eyeglasses 100 are in the worn state, or the distance between the ear canal orifice of the corresponding ear and the extension line of the line connecting both the front sound hole 35 and the rear sound hole 36 is small, that is, a certain error range is allowed, for example, an error range of-0.5 cm to 0.5cm, that is, when the distance between the ear canal mouth of the corresponding ear and the extension line of the connecting line of the front sound hole 35 and the rear sound hole 36 is between-0.5 cm to 0.5cm, it can also be said that "the front sound hole 35 and the rear sound hole 36 may be arranged such that the extension line of the line passes through the ear canal mouth of the corresponding ear when the eyeglasses 100 are in the wearing state".

The sound pressure spatial distribution of a dipole loudspeaker is as follows:

where p (r, θ) represents a sound pressure at a certain point (r, θ) in space, j represents an imaginary symbol, w represents an angular frequency, ρ represents the density of the transmission medium, a is a constant, and k represents a wave number.

On the perpendicular bisector of two lines of preceding sound hole 35 and back sound hole 36 of dipole speaker 30, form the minimum of acoustic pressure, form the maximum of acoustic pressure on the extension line of two lines of preceding sound hole 35 and back sound hole 36 of dipole speaker 30, consequently, preceding sound hole 35 and back sound hole 36 of dipole speaker 30 set up mutually oppositely, and preceding sound hole 35 and back sound hole 36 can set up to the extension line of both lines and be favorable to forming the great value of acoustic pressure in the ear canal mouth department of corresponding ear when glasses 100 is under the state of wearing through the ear canal mouth of corresponding ear.

Referring to fig. 5, fig. 5 is a graph illustrating sound pressure radiation effect of the glasses shown in fig. 1. When two dipole speakers 30 are arranged on each temple 20, and the difference between the distances between the two dipole speakers 30 located on the same temple 20 and the ear canal opening is set to be equal to the product of the time delay and the sound velocity, the front sound hole 35 and the rear sound hole 36 are set such that the extended lines of the connection lines of the two pass through the ear canal opening of the corresponding ear when the eyeglasses 100 are in a wearing state, the multiple sound waves are superimposed in the direction toward the ear canal opening, which is favorable for forming a larger value of the sound pressure in a first direction (at a1 in fig. 5) toward the ear canal opening and a second direction (at a2 in fig. 5) away from the ear canal opening, and the multiple sound waves are offset in a direction (at B in fig. 5) perpendicular to the first direction and the second direction, which is favorable for forming a smaller value of the sound pressure, thereby being favorable for improving the audio effect and reducing the sound leakage.

Because the front sound hole 35 and the rear sound hole 36 of the dipole loudspeaker 30 are arranged oppositely, and the front sound hole 35 and the rear sound hole 36 are arranged such that the extended lines of the connecting lines of the front sound hole 35 and the rear sound hole 36 pass through the ear canal openings of the corresponding ears when the eyeglasses 100 are worn, and the first sound outlet hole 202 is correspondingly communicated with the front sound hole 35 and the second sound outlet hole 203 is correspondingly communicated with the rear sound hole 36, the first sound outlet hole 202 and the second sound outlet hole 203 corresponding to each dipole loudspeaker 30 are also arranged oppositely. As shown in fig. 3 and 4, the temples 20 include first and second sides that are oppositely disposed, the first side faces the ear canal orifice in a wearing state, the first sound outlet holes 202 may be opened at the first side of the corresponding temples 20 such that the first sound outlet holes face the ear canal orifice in the wearing state, and the second sound outlet holes 203 may be opened at the second side of the corresponding temples 20. In some embodiments, the second sound outlet hole 203 may also be opened on the outer side of the temple 20 in a wearing state. When the glasses 100 are worn, the outer side surface is an appearance surface, and the second sound outlet holes 203 are opened on the second side surface, i.e., the upper side surface, of the corresponding temples 20, which is beneficial to improving the appearance effect of the glasses 100.

The bluetooth circuitry 41 may be used to receive audio signals from another electronic device. The audio processing circuit 42 is used to control the electrical signal of one 30b of the two dipole speakers 30 located at the same temple 20 that is closer to the ear canal ostium to be delayed relative to the electrical signal of one 30a that is farther from the ear canal ostium.
