Various modifications to the disclosed embodiments will be apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the present disclosure. Thus, the present disclosure is not limited to the embodiments shown, but is intended to conform to the broadest scope of the claims.

The terminology used herein is for the purpose of describing specific exemplary embodiments only and is not intended to be limiting. As used herein, the singular forms may also mean plural forms, unless the context clearly indicates otherwise. In addition, it should be understood that the terms "comprises", "comprising", "includes" and/or "comprising" when used in this disclosure indicate the presence of the claimed features, integers, steps, operations, elements and/or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and/or groups thereof.

These and other features and characteristics of the present disclosure, as well as the manner of operation and operation of the associated structural elements, the combination of parts, and the economy of manufacture, may become more apparent upon consideration of the following description with reference to the accompanying drawing(s), each of which is part of this specifications. However, it should be clearly understood that the drawings are for illustration and description only and are not intended to limit the scope of the present disclosure. It is understood that the drawings are not to scale.

It should be understood that although the terms "first", "second", "third", etc. may be used in this document to describe various elements, these elements should not be limited to these terms. These terms are only used to distinguish one element from another. For example, the first element may be referred to as the second element, and similarly the second element may be referred to as the first element, without departing from the scope of the illustrative embodiments of the present disclosure.

Spatial and functional relationships between elements are described using a variety of terms, including such terms as "connected", "attached" and "established". Unless a relationship is explicitly indicated as "direct" when describing a relationship between the first and second elements in this disclosure, this relationship includes a direct relationship when there are no other intermediate elements between the first and second elements, and also an indirect relationship when there are no other intermediate elements between the first and second elements, and also an indirect relationship when between the first and second elements. the second elements present (spatially or functionally) one or more intermediate elements. In contrast, when an element is referred to as "directly" connected, attached, or positioned in relation to another element, there are no intermediate elements. Other words used to describe the relationship between elements should be interpreted in a similar way (for example, "between" or "directly between", "adjacent" or "immediately adjoining").

It should also be understood that terms such as "top", "bottom", "top", "bottom", "vertical", "side", "above", "below", "up (pointing up), "down" (pointing down), "left side", "right side", "left", "right", "horizontal" and other similar spatial orientation terms are used in a relative sense to describe positions or orientations of certain surfaces/parts/components of the acoustic device relative to other such characteristics of the acoustic device when the acoustic device is in its normal operating position, and may change if the position or orientation of the acoustic device is changed.

An aspect of the present disclosure relates to an acoustic device. The acoustic device may include a vibrating speaker, a feed mechanism, and a support component. The vibrating speaker may be configured to generate a vibrating signal representing sound in accordance with the electrical signal. The feed mechanism may be mechanically connected to the vibrating speaker. The feed mechanism may be configured to contact the user through the contact area on the feed mechanism and provide a vibration signal to the user through the contact area. The contact area of the feed mechanism may be located at a distance from the vibration speaker and have a lower vibration intensity than the vibration speaker. The support component may be mechanically connected to the vibrating speaker via a feed mechanism. The support component may be configured to support the feed mechanism.

In some embodiments, the area of contact between the contact area of the feed mechanism and the user may change in response to the vibration signal. During the vibration signaling process, when the vibration speaker vibrates towards the user, the contact area between the contact area of the feed mechanism and the user (or the user's skin) may gradually decrease, and is smaller than the contact area when the vibration speaker directly contacts the user, the more thereby further reducing the vibration sensation of the user. In addition, since the contact portion of the feed mechanism has a lower vibration intensity than that of the vibration speaker, the vibration intensity of the vibration signal supplied to the user by the feed mechanism can be reduced, thereby further reducing the vibration sensation of the user.

In some alternative embodiments, the feed mechanism may be a resilient member with an arcuate portion, such that the area of contact between the contact portion of the feed mechanism and the user may not change (or not substantially change) in response to the vibration signal. During the process of supplying a vibration signal, when the vibration speaker vibrates towards the user, a part of the vibration signal generated by the vibration speaker can be converted into an elastic deformation of the elastic member. Thus, the user's vibration sensation may be less than the user's vibration sensation in which the vibration speaker is in direct contact with the user.

Moreover, the vibrating speaker can be placed such that the surface of the vibrating speaker faces the ear canal of the user. Thus, when the vibration speaker vibrates towards the user, the vibration speaker can cause the air around the vibration speaker to vibrate and transmit the sound signal(s) to the user through the air, thereby increasing the intensity of the sound provided to the user. As a result, the vibrating speaker can be designed to reproduce deeper low frequency signals so that the sound energy in the low frequency range becomes richer, thereby enhancing users' perception of sound (such as music) at low frequency signals and allowing users to experience more low frequency effects. .

In FIG. 1 is a block diagram illustrating an exemplary acoustic device according to some embodiments of the present disclosure. For example, acoustic device 100 may be an acoustic device for an electronic device such as headphones, headphones, virtual reality glasses, augmented reality glasses, and so on. As shown in FIG. 1, the acoustic device 100 may include a vibration speaker 110, a feeder 120, and a support component 130. The vibration speaker 110 may be coupled to the support component 130 via the feeder 120.

The vibration speaker 110 may be configured to generate vibration signal(s) representing sound(s) in accordance with the electrical signal(s). The electrical signal(s) may (may) contain audio information. Audio information may refer to a video file or an audio file with a specific data format, and may also refer to general data or a file that can eventually be converted to audio using certain approaches. The electrical signal(s) can(s) be received from a signal source such as a microphone, computer, mobile phone, MP3 player, etc. For example, a microphone may receive audio signals from a sound source. The microphone may then convert the received audio signal(s) into electrical signal(s) and transmit the electrical signal(s) to the vibration speaker 110. As another example, the vibration speaker 110 may be connected to the MP3 player or may communicate with it, the MP3 player may directly transmit electrical signal(s) to vibrating speaker 110. In some embodiments, vibrating speaker 110 may be connected to and/or communicate with a signal source via a wired connection, wireless connection, or a combination thereof. The wired connection may include, for example, an electrical cable, an optical cable, a telephone wire, and the like. or any combination of them. The wireless connection may include a Bluetooth™ network, a local area network (LAN), a wide area network (WAN)), a short range wireless communication (NFC) network, a ZigBee™ network, and the like. or any combination of them.

In some embodiments, vibration speaker 110 may be a bone conduction speaker. In some embodiments, vibration speaker 110 may be a composite speaker. In such cases, the vibrating speaker 110 can generate bone conduction waves and air conduction waves that can be perceived by a wearer. It should be noted that the vibrating speaker 110 may be of various types, such as an electromagnetic type (for example, a moving coil type, a moving core type, etc.), a piezoelectric type, an inverse piezoelectric effect type, an electrostatic type, etc. which are not limited to this disclosure.

The feeder 120 may be mechanically coupled to the vibration speaker 110. Thus, the feeder 120 may receive vibration signal(s) from the vibration speaker 110. When the acoustic device 100 is put on the user, an angle may be formed between the feeder 120 and the user. . As used herein, the angle between the feed mechanism 120 and the user refers to the angle between the long axis of the feed mechanism 120 and the plane in which the user's skin is located. In some embodiments, the angle may range from 0° to 90°, or 0° to 70°, or 5° to 50°, or 10° to 50°, or 10° to 30°, etc. P.

The feeder 120 may be configured to contact the user through the contact area on the feeder 120 and deliver the received(e) vibration signal(s) to the user through the contact area. In some embodiments, the area of contact between the delivery mechanism 120 and the user (eg, the user's skin) may change in response to the vibration signal(s). In some embodiments, the region of the user's body on which the contact portion of the feed mechanism 120 is located and/or with which it contacts may include the forehead, neck (e.g., throat), face (e.g., the area around the mouth, chin), crown, mastoid process, area around the ear, temple, etc. or any combination of them.

The contact area of the feed mechanism 120 may be located at a distance from the vibrating speaker 110. The vibration speaker 110 may vibrate about the axis of rotation near the contact area of the feed mechanism 120. In such cases, the contact area of the feed mechanism 120 may be closer to the axis of rotation than the contact area of the vibrating speaker 110. Thus, the contact area on the feed mechanism 120 may have a lower vibration intensity than that of the vibrating speaker 110, thereby reducing the vibration transmitted to the user. . For example, the feed mechanism 120 may include an elastic member having at least one arcuate portion. The contact portion of the feed mechanism 120 may be located on a convex portion of the at least one arcuate portion. The vibration speaker 110 may vibrate around the contact area in response to the vibration signal(s). Additional descriptions of the arcuate portion can be found elsewhere in this disclosure (eg, in the description with reference to FIG. 3). As another example, the feed mechanism 120 may include a coupling block, a vibration plate, and an elastic member. Vibration speaker 110 may be located on the top surface of the connection block, and a vibration plate may be attached to one end of the connection block. The contact portion of the feeder 120 may be located on the vibrating plate. The support component 130 may be connected to a connection block or vibrating plate via a resilient member. The vibrating speaker 110 may vibrate around the connection point between the support component 130 and the elastic element in response to the vibration signal(s). Additional description of the feed mechanism with the connection block, vibrating plate and elastic element can be found elsewhere in this disclosure (for example, in the description with reference to Fig. 2).

In some embodiments, the contact portion of the delivery mechanism 120 may be located in an area around the ear in which the vibrating speaker 110 may be positioned such that the surface of the vibrating speaker 110 faces the user's ear canal. Thus, when the vibration speaker vibrates, the vibration speaker 110 can cause the air around the vibration speaker to vibrate and generate air conduction waves. Air conduction waves can be transmitted to the ear through the air, thereby increasing the intensity of the sound delivered to the user. Accordingly, the user can not only hear the bone conduction waves generated by the vibration of the contact portion of the feed mechanism 120, but also hear the air conduction waves generated by the vibration speaker 110 driving the ambient air.

In some alternative embodiments, the vibrating speaker housing 110 may include one or more openings, such as on the side wall of the housing or on the side facing the user's ear canal. Thus, when vibrating speaker 110 vibrates, air conduction waves generated within the housing of vibrating speaker 110 (e.g., due to vibration of a vibrating component within the housing) may be transmitted to the outside of the housing through one or more apertures and further transmitted to the user's ear. In some embodiments, one or more openings of vibrating speaker 110 may be positioned toward the user's ear canal when the user is wearing acoustic device 100. Accordingly, the user may further hear air conduction waves transmitted by one or more openings of vibration speaker 110, thereby enhancing the intensity of the sound the user hears.

The support component 130 may be mechanically connected to the vibrating speaker 110 via the feed mechanism 120 . The support component 130 may be configured to support the delivery mechanism 120 and/or the vibrating speaker 110 so that the delivery mechanism 120 can contact the user's skin.

In some embodiments, the support component 130 may include a locking portion that allows the acoustic device 100 to be better fixed to the user and prevent it from falling during use by the user. In some embodiments, the fixation site may have any shape suitable for a part (e.g., ear, head, neck) of the human body, such as U-shaped, C-shaped, circular annular, elliptical, semi-circular, etc. so that the acoustic device 100 can be independently worn on the user's body. For example, the shape of the anchoring portion of the support component 130 may conform to the shape of the human ear so that the acoustic device 100 can be independently worn on the user's ear. As another example, the shape of the fixing portion of the support component 130 may conform to the shape of a person's head, so that the support component 130 can be hung on the user's head, which prevents the acoustic device 100 from falling easily.

In some embodiments, support component 130 may be a shell structure with a hollow interior. The hollow interior may contain a battery, a circuit board, a Bluetooth device, or the like, or any combination thereof. In some embodiments, support component 130 may be made from a variety of materials such as metallic materials (eg, aluminum, gold, copper, etc.), alloys (eg, aluminum alloys, titanium alloys, etc.), plastic materials (for example, polyethylene, polypropylene, epoxy resin, nylon, etc.), fibrous materials (for example, acetate fiber, propionic acid fiber, carbon fiber, etc.), etc. In some embodiments, the implementation of the support component 130 may be provided with a shell. The shell can be made of soft materials with a certain resilience, such as soft silica gel, rubber, etc., which can provide better contact for users.

It should be noted that the above description of acoustic device 100 is provided for illustrative purposes only and is not intended to limit the scope of the present disclosure. As for those of ordinary skill in the art, they can make numerous changes and modifications in accordance with the teachings of this disclosure. However, these changes and modifications are not outside the scope of this disclosure. In some embodiments, the connection between any two components (e.g., vibrating speaker 110, delivery mechanism 120, and support component 130) of acoustic device 100 may include gluing, riveting, threaded connection, integral molding, vacuum connection, or the like, or any combination of them.

In some embodiments, the acoustic device 100 may further include an auxiliary support component configured to assist the support component 130 to support the vibration speaker 110 through contact with the user. The auxiliary support component may have a rod-like structure, and the end of the auxiliary support component may be directly connected to the vibration speaker 110. Accordingly, when the user wears the acoustic device 100, the auxiliary support component can be in contact with the user and the vibration speaker 110, so that the vibration speaker 110 may transmit a portion of the vibration signal(s) to the user via the auxiliary support component, thereby further enhancing the intensity of the sound heard by the user.

In FIG. 2 shows exemplary process related images of an exemplary acoustic device transmitting vibration signal(s) to a user, in accordance with some embodiments of the present disclosure. As shown in FIG. 2 (e.g., image 2a), an acoustic device 200 may include a vibrating speaker 210, a feeder 220 (components in dotted box 220), and a support component 230.

The vibration speaker 210 may be connected to the support component 230 via the feed mechanism 220 . Vibration speaker 210 may generate vibration signal(s) representing sound according to electrical signal(s). Just by way of example, vibrating speaker 210 may include a magnetic circuit component, a vibrating component, and a housing. The magnetic circuit component may be configured to generate a magnetic field. The vibration component can convert an electrical signal input to the vibration component into a mechanical vibration signal in a magnetic field. The housing may include a panel facing the side of the human body and a rear portion opposite the panel. The housing may contain a vibration component. In some embodiments, the implementation of the vibration component may cause vibration of the panel and the back. Vibrating speaker 210 may generate various resonant peaks. In some embodiments, vibrating speaker 210 may provide one or more low frequency resonant peaks in a frequency range of less than 500 Hz, or in a frequency range of less than 800 Hz, or in a frequency range of less than 1000 Hz. The low-frequency(e) resonant(e) peak(s) may be associated(s) with the elastic moduli of the vibration component. The smaller the elastic moduli of the vibration component, the lower the low frequency resonant peak of the vibration speaker 210 may be.

The feed mechanism 220 may provide the vibration signal(s) to the user (eg, to the user's cochlea) through contact with the user. In some embodiments, the feed mechanism 220 may include a coupling block 222, a vibration plate 224, and a resilient member 226. A contact portion of the feed mechanism 220 that contacts a user may be located on the vibration plate 224.

In some embodiments, connector block 222 may be a two-end structure (eg, a first end E1 and a second end E2). For example, the connector block 222 may have a rod-like structure, a plate-like structure, and so on. with two ends. Vibration speaker 210 may be connected to vibration plate 224 via junction block 222. For example, a side wall (eg, bottom side wall) of vibration speaker 210 may be connected to a side wall (eg, top side wall) of junction block 222. Optionally, vibration speaker 210 may be located on the top side or connected to the first end E1 of the connection block 222. For example, when the connection block 222 is a rectangular rod, the vibration speaker 210 may be located on the top side wall of the connection block 222 as shown in FIG. For brevity, the top side of the connector block 222 refers to the side of the connector block 222 that faces away from the wearer's skin, and the bottom side of the connector block 222 refers to the side of the connector block 222 that faces the user's skin. Similarly, the top side of the vibration speaker 210 refers to the side of the vibration speaker 210 facing away from the user's skin, and the bottom side of the vibration speaker 210 refers to the side of the vibration speaker 210 that faces the user's skin. In some embodiments, when the connector block 222 is a rod-like structure, the cross-section of the rod can be any other shape, such as a rectangle, triangle, circle, ellipse, regular hexagon, irregular shape, etc. In some embodiments, when connector block 222 is a sheet, the shape of the sheet may include a rectangle, an ellipse, an irregular shape, and so on.

The vibration plate 224 may be connected to the underside of the connection block 222 at the second end E2. The vibrating plate 224 as well as the contact portion of the feeder 220 may be spaced away from the vibrating speaker 210. The vibrating plate 224 may be configured to contact the user (as shown in FIG. 2, the dotted line 240 may be roughly considered to be the user's skin) for transmitting the vibration signal(s) to the user. In some embodiments, vibration plate 224 may be a block, such as a wedge block, that allows or causes vibration speaker 210 to be suspended over the user's skin, thereby forming an angle (e.g., θ in image 2a in FIG. 2) between the top surface or bottom the surface of the connector block 222 and the surface of the user's skin. In some embodiments, the angle between the top surface or bottom surface of connector block 222 and the user's skin surface may be in the range of 0° to 90°, or 0° to 70°, or 5° to 50°, or 10° to 50°. °, or from 10° to 30°, etc. In some embodiments, the angle between the top surface or bottom surface of connector block 222 and the surface of the user's skin may also be referred to as the angle between the feed mechanism 220 and the user's skin 240 (or the plane in which the skin is located).

Resilient member 226 and vibration plate 224 may be located at the same end of connector block 222, i.e., elastic member 226 may also be connected to the second end E2 of connector block 222. The upper surface of vibration plate 224 may have a convex structure 228 (as shown figure 2). The two ends of the elastic member 226 may be respectively connected to the convex structure 228 and the second end E2 of the connecting block 222. In some embodiments, the elastic member 226 may be a sheet-like structure or a rod-like structure with a certain resiliency.

The first end of the support component 230 may be connected to the elastic element 226 at any point (for example, at the center point) of the elastic element 226. In some embodiments, the first end of the support component 230 may be connected to the elastic element 226 directly or through the connecting element 232. For example , the first end of the support component 230 may be connected to the center of the resilient element 226 directly or through the coupling element 232. When the acoustic device 200 is attached to the user, the support component 230 may be considered stationary with respect to the user, and in such cases, the vibrating speaker 210 may result in rotation of the coupling block 222 and the vibration plate 224 around a particular connection point 250 (eg, the center point of the elastic element 226) between the support component 230 and the elastic element 226 in response to the vibration signal(s).

According to images 2a and 2b in FIG. 2, image 2a represents the initial state of the acoustic device 200 during the vibration signaling process, and image 2b represents the intermediate state of the acoustic device 200 during the vibration signaling process. The arrow A indicates the vibration direction of the vibration speaker 210, and the length of the arrow A indicates the intensity of the vibration.

When the acoustic device 200 is in its initial state (image 2a), the angle between the feed mechanism 220 and the user's skin 240 has a value equal to , and at this time, the contact area between the vibration plate 224 and the user's skin 240 is the largest during the vibration signaling process. When the acoustic device 200 is in an intermediate state (picture 2b), the angle between the delivery mechanism 220 and the user's skin 240 may be smaller than the angle between the delivery mechanism 220 and the user's skin 240 in the initial state of the acoustic device 200. Accordingly, the contact area between the delivery mechanism 220 feed and skin 240 of the user may change in response to the vibration(s) signal(s). For example, during the process, as the vibrating speaker 210 vibrates around a particular connection point 250 towards the user's skin 240, the angle between the feed mechanism 220 and the user's skin 240 may gradually decrease (i.e., in image 2b ). In such cases, the contact area between the vibration plate 224 and the user's skin 240 in the intermediate state of the acoustic device 200 may be smaller than the contact area between the vibration plate 224 and the user's skin 240 in the initial state of the acoustic device 200. As a result, during a process in which the vibration speaker 210 provides the vibration signal(s) to the user, the user's feeling of vibration may be reduced.

Moreover, since the vibration plate 224 is at a distance from the vibration speaker 210, and the distance from the vibration plate 224 to the specific connection point 250 is less than the distance from the vibration speaker 210 to the specific connection point 250, during the vibration signaling process, the vibration plate 224 may have a lower vibration intensity than the vibration speaker 210, thereby further reducing the user's feeling of vibration. Just as an example, the arrow B indicates the vibration of a point in the contact area, and the length of the arrow B indicates the vibration intensity of the point. Since the perpendicular distance from a specific connection point 250 to arrow B is less than the perpendicular distance from a specific connection point 250 to arrow A, the vibration intensity of arrow A (that is, the length of arrow A) may be greater than the vibration intensity of arrow B (that is, the length arrows B).

Accordingly, by using the feed mechanism 220, the vibration emitted from the vibration speaker 210 can be reduced, protecting the user from the unpleasant vibration sensation in the low frequency range. Based on this, the frequency response of the vibration speaker 210 can be designed more flexibly to adapt to different needs. For example, the lowest resonant peak of the vibration speaker 210 may be moved to a lower frequency range to provide the user with more abundant low frequency signals. As described above, the lowest resonant peak of the vibration speaker 210 can be adjusted by varying the elastic moduli of the vibration component of the vibration speaker 210. In some embodiments, the modulus of elasticity of the vibration component of the vibration speaker 210 can be calculated such that the lowest resonant peak of the vibration speaker 210 is less than 2500 Hz or less than 2000 Hz or less than 1500 Hz or less than 1200 Hz or less than 1000 Hz or less than 800 Hz or less than 500 Hz or less than 300 Hz or less than 200 Hz or less than 100 Hz or less 90 Hz or less than 50 Hz.

It should be noted that the above description is for illustrative purposes only and is not intended to limit the scope of the present disclosure. As for those of ordinary skill in the art, they can make numerous changes and modifications in accordance with the teachings of this disclosure. However, these variations and modifications are not outside the scope of this disclosure. For example, vibrating speaker 210 may be connected directly to vibrating plate 224, i.e., a connection block 222 may be omitted. In such cases, resilient member 226 may be directly coupled to vibrating speaker 210. As another example, acoustic device 200 may further include one or more additional components, such as an auxiliary support component (not shown). As another example, the contact portion of the delivery mechanism 220 may be located in a region around the ear in which the vibrating speaker 210 may be positioned such that the surface of the vibrating speaker 210 faces the user's ear canal to better transmit air conduction waves to the ear. . In some embodiments, the connection between any two components (e.g., vibrating speaker 210, junction block 222, vibrating plate 224, support component 230, etc.) of acoustic device 200 may include joining, riveting, screwing, molding in one whole, vacuum connection, or the like, or any combination thereof.

In FIG. 3 shows exemplary process related images of an exemplary acoustic device providing vibration signal(s) to a user, in accordance with some embodiments of the present disclosure. As shown in FIG. 3, the acoustic device 300 may be similar to the acoustic device 200 shown in FIG. 2. The acoustic device 300 may include a vibration speaker 310, a feed mechanism 320, and a support component 330.

The vibration speaker 310 may be connected to the support component 330 via the feed mechanism 320 . Vibration speaker 310 may generate vibration signal(s) representing sound in accordance with electrical signal(s). Vibration speaker 310 may be similar or the same as vibration speaker 210 shown in FIG. 2.

The feed mechanism 320 may include a resilient member. The elastic element may include a connecting section 322 and an arcuate portion 324, wherein the first end of the connecting section 322 is connected to the first end E3 of the arcuate section 324. In some embodiments, the elastic element (for example, the connecting section 322 and/or the arcuate section 324) may be made of various elastic materials such as metallic materials (eg aluminum, gold, copper, etc.), alloys (eg aluminum alloys, titanium alloys, etc.), plastics (eg polyethylene, polypropylene, epoxy resin, nylon, etc.), fibrous materials (such as acetate fiber, propionic acid fiber, carbon fiber, etc.), etc.

The vibration speaker 310 may be mechanically connected to the connection section 322. For example, when the connection section 322 is a sheet-like structure, the vibration speaker 310 may be located on the top surface of the connection section 322. As another example, when the connection section 322 is a rod-like structure, the vibrating speaker 310 may be located on the upper surface of the connecting section 322, or the side wall of the vibrating speaker 310 may be connected to the second end of the connecting section 322.

The convex portion of the arcuate portion 324 may be configured to contact the skin 340 of the user, thus the vibrating speaker 310 may provide vibration signal(s) to the user via the feeder 320. In such cases, the area of contact between the arcuate portion 324 and the user's skin 340 may be smaller than that of the contact portion of the feed mechanism 220 shown in FIG. 2. The area of contact between the feed mechanism 320 and the user's skin 340 may not change substantially in response to the vibration signal(s). The vibrating speaker 310 may be hung on the user's skin, and an angle (e.g., in image 3a in FIG. 3). In some embodiments, the angle between the connecting portion 322 and the user's skin surface 340 may range from 0° to 90°, or from 0° to 70°, or from 5° to 50°, or from 10° to 50°, or from 10° to 30° etc. In some embodiments, the angle between the connecting portion 322 and the surface of the user's skin 340 may also be referred to as the angle between the feed mechanism 320 and the user's skin 340 (or the plane in which the user's skin is located).

In some embodiments, the implementation of the convex part of the arcuate section 324, which is in contact with the skin 340 of the user, may also be referred to as the contact area 350 of the feed mechanism 320. The contact portion 350 of the feed mechanism 320 may be spaced away from the vibrating speaker 310. The second end E4 of the arcuate portion 324 may be connected to one end of the support component 330. When the acoustic device 300 is attached to the user, the support component 330 can be considered stationary with respect to the user, and in such cases, the vibrating speaker 310 may rotate or vibrate the feed mechanism 320 (i.e., the elastic member) of the connecting portion 322 and the arcuate portion 324) to vibrate or rotate about the contact portion 350 in response to the vibration signal(s). ). In some embodiments, the implementation of the second end E4 of the arcuate section 324 may be connected to the support component 330 through the connecting element 332.

According to images 3a and 3b shown in FIG. 3, image 3a represents the initial state of the acoustic device 300 during the vibration signaling process, and image 3b represents the intermediate state of the acoustic device 300 during the vibration signaling process. The arrow B indicates the vibration direction of the vibration speaker 310, and the length of the arrow B indicates the intensity of the vibration.

During the vibration signal delivery process, since the contact area between the arcuate portion 324 and the skin 340 of the user is very small, and the vibration signal(s) generated by the vibration speaker 310 is partially converted (converted) into the elastic deformation of the mechanism 320 delivery (eg, connecting portion 322 and/or arcuate portion 324), the user's vibration sensation can be reduced compared to the user's vibration sensation when the vibrating speaker 310 is in direct contact with the user's skin 340.

Moreover, since the contact area 350 is at a distance from the vibration speaker 310, during the vibration signal process, the contact area 350 may have a lower vibration intensity than the vibration intensity of the vibration speaker 310, thereby further reducing the user's feeling of vibration. Just as an example, the arrow B indicates the vibration of a point near the contact portion 350, and the length of the arrow B indicates the intensity of the vibration of the point. Since the perpendicular distance from contact portion 350 to arrow B is less than the perpendicular distance from contact portion 350 to arrow A, the vibration intensity of arrow A (i.e. arrow length A) may be greater than the vibration intensity of arrow B (i.e. arrow length B ).

Accordingly, by using the feed mechanism 320, the vibration emitted from the vibration speaker 310 can be reduced, protecting the user from the unpleasant feeling of vibration in the low frequency range. Based on this, the frequency response of the vibration speaker 310 can be designed more flexibly to adapt to different needs. For example, the lowest resonant peak of the vibration speaker 310 can be moved to a lower frequency range to provide the user with more abundant low frequency signals. As described above, the lowest resonant peak of the vibration speaker 310 can be adjusted by changing the moduli of the vibration component of the vibration speaker 310. In some embodiments, the modulus of elasticity of the vibration component of the vibration speaker 310 can be designed such that the lowest resonant peak of the vibration speaker 310 is less than 2500 Hz or less than 2000 Hz or less than 1500 Hz or less than 1200 Hz or less than 1000 Hz or less than 800 Hz or less than 500 Hz or less than 300 Hz or less than 200 Hz or less than 100 Hz or less 90 Hz or less than 50 Hz.

For illustrative purposes only, only one resilient element is described in the acoustic device 300. However, it should be noted that the acoustic device 300 in the present disclosure may also include multiple resilient elements, and thus the vibration signal(s) may (may) ) also be fed together by several elastic elements. In some embodiments, the implementation of the elastic element 320 may include several arcuate sections, and thus, the vibration(s) signal(s) may also be fed together by several arcuate sections. For example, several arcuate sections may be located next to each other.

It should be noted that the above description is for illustrative purposes only and is not intended to limit the scope of the present disclosure. As for those of ordinary skill in the art, they can make numerous changes and modifications in accordance with the teachings of this disclosure. However, these changes and modifications are not outside the scope of this disclosure. For example, the arcuate portion 324 may be connected directly to the vibration speaker 310, ie, the connecting portion 322 may be omitted. As another example, acoustic device 300 may further include one or more additional components, such as an auxiliary support component (not shown). As another example, the contact portion 350 of the delivery mechanism 320 may be located in the region around the ear, in which the vibrating speaker 310 may be positioned so that the surface of the vibrating speaker 310 faces the user's ear canal for better transmission of air conduction waves to the ear. . In some embodiments, the connection between any two components (e.g., vibrating speaker 310, arcuate portion 324, connecting portion 322, support component 330, etc.) of the acoustic device 300 may include joining, riveting, screwing, molding in one whole, vacuum connection, or the like, or any combination thereof.
