Implementation of the invention

In order to illustrate the technical solutions related to the embodiments of the present disclosure, the following is a brief description of the drawings, which are referred to in the description of the embodiments. Obviously, the drawings described below are only some examples or embodiments of the present disclosure. Those of ordinary skill in the art can apply the present disclosure to other similar scenarios in accordance with these drawings without further creative effort. Unless it is obvious from the context or specifically shown, like reference numerals throughout the drawings refer to like structural components or operations.

As used in the present disclosure and the appended claims, the singular forms include the plural forms of the entity being defined, unless the context clearly dictates otherwise. In general, the terms "comprise", "comprises" and/or "comprising", "include", "includes" and/or "including" only indicate that the steps and elements that have been are clearly defined and these steps and elements are not meant to be exhaustive. The methods or devices may also include other steps or elements.

It should be understood that the terms "data block", "system", "mechanism", "device", "assembly", "unit" and/or "unit" are used as a way to distinguish between various components, elements, parts, sections or assemblies. different levels. However, other terms may be replaced by another expression if they serve the same purpose.

Various terms are used to describe the spatial and functional relationships between elements (eg, between layers). The terms include "connected", "glued", "coupled", "coupled", etc. Unless explicitly indicated by the term "direct", when describing the relationship between the first and second elements in the present description, the relationship includes a direct relationship between the first and second elements without other intermediate elements, as well as an indirect (spatial or functional) relationship between the first and second elements with one or more intermediate elements. In contrast, when an element is referred to as "directly" coupled, articulated, conjugated, or associated with another element, there are no intermediate elements. In addition, the spatial and functional relationships between elements can be implemented in various ways. For example, a mechanical connection between two elements may be a welded joint, a key joint, a pin joint, an interference joint, and so on. or any combination of them. In other words, those used to describe relationships between elements should be interpreted in a similar way (eg, "between", "with", "adjacent", "immediately adjoining", etc.).

The present disclosure provides an acoustic device. The acoustic device may include a housing, one or more sound receiving nodes, and one or more channel nodes. The housing may have a containment space and one or more communication openings. Each communication opening connects the enclosing space and the outer space. One or more sound receiving nodes may be located in the containing space and may be configured to pick up sound through the communication openings. One or more channel nodes may be located in the containing space. At least one of one or more channel catches is located between the sound receiving node in one or more sound receiving nodes and the communication opening of one or more communication holes, so that the sound is transmitted to the sound receiving node unit through at least one of the one or more channel nodes after passing through communication hole. Thus, by arranging one or more channel nodes, it is possible to widen the sound path of the respective sound receiver node, thereby reducing the "wind noise" phenomenon caused by the short sound path of the sound receiver node. In addition, in some embodiments, by accommodating multiple sound receiving nodes that can independently perform sound pickup and signal processing (e.g., amplification), the acoustic device can also adapt to sounds from different directions, allowing the wearer (e.g., user) to hearing impaired) adapt to sounds from different directions and improve the user's hearing effect.

In some embodiments, the acoustic device may also include multiple speaker nodes, a control circuit node, and multiple interactive nodes. A control scheme node can include multiple controls. Each control may correspond to at least one speaker node from multiple speaker nodes. Each interactive node corresponds to one of several speaker nodes and a corresponding speaker node control. The interactive node is configured to launch a control corresponding to the interactive node to control the corresponding speaker node to implement the function corresponding to the user's work instruction in response to receiving the user's work instruction. In this way, a hearing impaired person (such as a user with normal hearing in one ear and a hearing impaired in the other ear) can adaptively adjust the two speaker units according to actual needs to adapt to different hearing in two ears, in order to avoid sound, which is always heard as "big on one side and quiet on the other", thereby improving the user experience.

In some embodiments, channel assembly 130 may include a first port (which may also be referred to as an audio inlet), a conduit, and a second port (which may also be referred to as an audio outlet). In some embodiments, the first port and communication port may be butt-jointed, and the second port may be adjacent to the sound receiver assembly so that sound is alternately transmitted to the sound receiver assembly through the communication hole, the first port, the conduit, and the second port. For more information regarding the channel node, reference should be made elsewhere in this disclosure (eg, FIGS. 6A-6B and related descriptions).

In some embodiments, acoustic device 100 may also include a control circuit node and one or more interactive nodes (not shown). The control circuit assembly may be used to control the acoustic device 100, such as volume control, on/off control, operation mode selection (eg, play/pause), wireless connection, communication control, and the like.

When the user wears the acoustic device 200, the earhook assembly 212 and the earhook assembly 214 may be hung on the user's ears, respectively, and the rear earhook assembly 216 may be positioned around the back of the user's head or neck so that the acoustic device 200 can be stably worn. .

In some embodiments, speaker assemblies 232 and 234 may be used to convert an audio signal (eg, an electrical signal) into mechanical vibrations at different frequencies. Two speaker assemblies (ie, speaker assemblies 232 and 234) may be located at the other ends of the two behind-the-ear assemblies. For example, the earhook assembly 212 and the earhook assembly 214 may respectively include containing spaces, the speaker assembly 232 may be positioned in the space to accommodate the earhook assembly 212, and the speaker assembly 234 may be positioned in the containing space of the earhook assembly 214 . When the acoustic device 200 is worn, the two speaker assemblies can transmit mechanical vibrations to the human auditory system through the wearer's bones and/or cochlea, thereby allowing the wearer to hear sound. In some embodiments, speaker assemblies 232 and/or 234 may be used independently of behind-the-ear assemblies. That is, speaker assemblies 232 and/or 234 may include speaker cabinets. Speaker housings may be coupled to earhook assemblies 212 and/or 214, and speaker assemblies 232 and/or 234 may be located outside of earhook assemblies 212 and 214. For more information regarding earhook assemblies, please refer to FIG. -4 and their detailed description.

In some embodiments, one or more components of acoustic device 200 may be located within a containment space defined by support assembly 210. For example, as shown in FIG. 2, battery assembly 240 may be located within the containment space of earhook assembly 212.

As another example, acoustic device 200 may also include one or more channel nodes. At least one of one or more channel nodes may be located between at least one of one or more sound receiving nodes and one of one or more communication holes on the reference node 210. For more information regarding the channel node, you should refer to the descriptions elsewhere in this disclosure (eg, to FIGS. 6A-6B and their detailed description).

In some embodiments, acoustic device 200 may include multiple (eg, 2, 3, 4, 5, etc.) sound receiving nodes. Each sound receiving node may be located adjacent to a communication hole on the support node 210 so that the sound receiving node can pick up sound through the corresponding communication hole. Multiple sound receiving nodes can be independent of each other and can independently perform sound pickup and signal amplification to independently pick up and process sounds from different directions, allowing the user (for example, a hearing impaired user) to adapt to sounds from different directions and improve hearing wearer. In some embodiments, several sound receiving nodes may be located some distance apart at different positions of the support node 210.

As another example, one of several sound receiving nodes may be located in the middle position (i.e., position I) of the rear bow assembly 216, and other sound receiving nodes may be located on one or both sides of the middle position at certain intervals. As an additional example, multiple sound receiving nodes may be located in the nodes 212 and/or 214 behind the ear at certain intervals. As another example, a portion of several sound-receiving nodes may be located in the same earhook node at certain intervals (for example, at positions E and B in Fig. 2 and/or at positions O and D in Fig. 4), the remaining parts may be located in the node 216 of the rear bow at certain intervals. In some embodiments, when the speaker assembly exists independently, multiple sound receiving assemblies may also be located within the speaker enclosure. In some embodiments, a portion of the multiple sound receiving assemblies may be spaced within the anchor assembly 210, and the remainder may be spaced within the speaker cabinet. In some embodiments, the position of the sound receiving node may also be referred to as the position of its corresponding communication opening.

It should be noted that, since the sound receiving unit is mainly used to pick up the voice of the user, the noise of the user's environment, etc., for the wearer (for example, a hearing impaired person), the characteristics of the sound receiving unit may affect clarity, stability, etc. of the sound received by the user through the acoustic device 200. In general, the sound pickup assembly may be positioned at any position on the speaker assembly 200. However, the closer the sound pickup assembly is to the speaker assembly, the more sensitive the sound pickup assembly is to shock to the speaker assembly and the more likely it is that that it will cause a "howl" due to the acoustic coupling of the sound pickup assembly and the speaker assembly. Thus, the installation position of the sound receiver assembly can be determined in accordance with the requirement for the "howl" threshold of the acoustic device 200. For more information on the relationship between the "howl" threshold of the sound receiver assembly and its relative position on the acoustic device, reference is made elsewhere in this disclosure.

Thus, the communication hole 350 (located in the speaker housing 330) may be located on the side of the earhook housing 310 at some distance from the speaker assembly (for example, at position C) or on the side at some distance from the connecting component 320 (for example, at position D) in order to avoid as much as possible "sound leakage" caused by the speaker assembly due to being picked up by the sound receiving node 340, thereby reducing the interaction of the speaker node with the sound receiving node 340. In addition, the sound receiving node 340 is located on the side of the containing space 360 at distance from the speaker assembly, which also reduces the transmission of mechanical vibrations generated by the speaker assembly to the sound pickup assembly 340, thereby reducing the occurrence of "howl" or noise generated by the sound pickup assembly 340. It should be noted that in some embodiments, the position of the communication hole 350 is also may be referred to as the position of the corresponding sound receiving node. In some embodiments, the implementation of the communication hole 350 may also be located in other places of the body 310 earhook. For example, communication port 350 may be located on the side of the earhook body 310 facing the speaker assembly, or on the side of the acoustic device (or earhook assembly 300) facing the user's head when the acoustic device (or earhook assembly 300) is worn, or may be located on the side (eg, in the O position) facing away from the wearer's head when the acoustic device (earhook assembly 300) is worn. As another example, communication hole 350 may be located at positions B, D, E, and so on. in the first body 312 behind the ear.

In some embodiments, as shown in FIG. 4, the connector component 320 may include a first resilient cover layer 321, a second resilient cover layer 322, and an elastic support component 323. One end of the resilient support component 323 may be connected to the earhook body 310 (eg, second earhook housing 314), and the other end of the elastic support component 323 may be connected to the speaker housing 330 (or speaker assembly). In some embodiments, a wire (not shown) may be located in the connection component 320. One end of the wire may be electrically connected to the sound pickup node 340, battery node, control circuit node, etc. located in the containing space 360, and the other end the wires may be electrically connected to the speaker assembly in the speaker housing 330.

In some embodiments, the first resilient cover layer 321 and the second resilient cover layer 322 may be formed using an injection molding process (eg, two-shot injection molding) and wrapped with a resilient support component 323 and a wire. In some embodiments, the elastic support component 323 may wrap the wire. In some embodiments, the resilient support component 323 may be bent and have a certain stiffness/strength so as to form the base shape of the earhook assembly 300, thereby making it easier for the wearer to wear the acoustic device. The first elastic coating layer 321 and the second elastic coating layer 322 may protect the elastic support component 323 and the wire wound thereon. In some embodiments, the first resilient cover layer 321 and the second resilient cover layer 322 may be made of soft materials with a certain flexibility, such as soft silicone, rubber, fibers, etc., to provide users with a better tactile feeling when worn. In some embodiments, the seams of the first resilient cover layer 321 and the second resilient cover layer 322 may separate the surface of the connecting component 320 into inner and outer surfaces that are opposed to each other. The exposed surface of the first resilient cover layer 321 can be used as the inside of the connector component 320, and the exposed surface of the second resilient cover layer 322 can be used as the outer surface of the connector component 320. It should be noted that when the acoustic device (or earhook assembly 300) is in the wearing state, the inner side of the connecting component 320 is closer to the wearer's skin than the outer side. Most of the inner side surface of the connecting component 320 is in contact with the user's ear and the area of the head adjacent to the ear.

In some embodiments, the auxiliary wire may be used in the manufacture of the connecting component 320. The auxiliary wire may be located adjacent the elastic support component 323. In some embodiments, the auxiliary wire and the elastic support component 323 may have essentially the same structural parameters, such as shape, length , radius of curvature, etc. In some embodiments, the auxiliary wire diameter may be less than or equal to the wire diameter. In addition, an elastic coating layer can be formed on the surfaces of the auxiliary wire and elastic support component 323 using an injection molding method, and then the auxiliary wire is drawn to obtain a connecting component 320. Finally, in the manufacture of an acoustic device, the wire can pass through the elastic coating layer ( that is, through the place where the auxiliary wire used to be). However, in the above-described injection molding process, since the auxiliary wire and the elastic support component 323 have a certain length and radius of curvature, they (especially the middle region) may deviate from the original position under the influence of the injection molding material, which may eventually lead to to uneven wall thickness of the elastic coating layer, which affects the molding quality of the joint component 320. Especially when the calculated wall thickness of the elastic coating layer is relatively small, if the acoustic device is used for a long time, the joint component 320 may exhibit a bad "skin tear" phenomenon, thereby affecting user experience.

In some embodiments, the resilient cover layer may be divided into a first resilient cover layer 321 and a second resilient cover layer 322. The first resilient coating layer 321 and the second resilient coating layer 322 can be injection molded in two steps. In particular, the through groove 324 may be formed on one side of one of the elastic coating layers (for example, the first elastic coating layer 321). The through groove 324 may extend along the extension direction of the first resilient coating layer 321 and may be used to receive the resilient support component 323 and the auxiliary wire. In addition, the second elastic coating layer 322 can be injection molded on the side where the through groove 324 of the first elastic coating layer 321 is located, and can cover the elastic support component 323 and the auxiliary wire after the first elastic coating layer 321 and the second layer are assembled and fixed. 322 of the resilient cover, wherein the auxiliary wire can be drawn out to form a guide channel parallel to the resilient support component 323 and in communication with the enclosing space 360 (not shown in FIG. 4). The guide channel can be used for laying the wire. It should be noted that since the through groove 324 has a certain depth, the first elastic coating layer 321 can partially surround the elastic support component 323 and the auxiliary wire to limit their position, in addition, the elastic support component 323 and the auxiliary wire can resist the impact of the casting material. under pressure, which is useful for solving the problem of deviation of the elastic support component 323 and the auxiliary wire from the original position.

In some embodiments, the depth of the through slot 324 may be equal to the radius of the slot, which has a larger diameter among the elastic support component 323 and the auxiliary wire. In some embodiments, the depth of the through slot 324 may be greater than the radius of the smaller diameter slot among the elastic support component 323 and auxiliary wire, and less than the radius of the larger diameter slot among the elastic support component 323 and the auxiliary wire. In some embodiments, the depth of the through slot 324 may be greater than the radius of the larger diameter slot among the resilient support component 323 and the auxiliary wire. In some embodiments, the number of through slots 324 may be two. The two through-slots 324 may be arranged side by side and used to receive the elastic support component 323 and the auxiliary wire, respectively, so that the leading channel and the elastic support component 323 are separated from each other. Thus, the elastic support component 323 and the auxiliary wire (or wire) do not interfere with each other. In some embodiments, the number of through slots 324 may be one, and the elastic support component 323 and the auxiliary wire may be co-located in the through slot 324, so that the elastic support component 323 may be exposed to the guide channel to simplify the construction of the connecting component 320.

In some embodiments, the earhook body 310 (eg, the second earhook body 314) may be connected to one end of the connector component 320 (eg, the resilient support component 323) using an injection molding process. In addition, the second resilient cover layer 322 may be bonded to the third resilient cover layer 316, which is designed to cover at least a portion of the outer surface of the earhook body 310 using an injection molding process. The first resilient coating layer 321 may be between the earhook body 310 and the speaker body 330 and not cover the outer surface of the earhook body 310. For example, the second elastic cover layer 322 may cover the outer surface of the first earhook housing 312, that is, the third elastic cover layer 316 and the second elastic cover layer 322 are the same cover layer, the first elastic cover layer 321 may be located between the first body 312 of the earhook and the speaker housing 330 and not cover the outer surface of the first earhook housing 312.

In some embodiments, the process of forming the earhook assembly 300 may include the following steps: step 1) forming, respectively, the speaker housing 330 and the second earhook housing 314 at both ends of the elastic support component 323; step 2) making the first resilient coating layer 321 with through grooves 324 using the first injection molding; step 3) connecting the first layer 321 of the elastic coating obtained in step 2) with the semi-finished product obtained in step 1) and the auxiliary wire; step 4) forming the second elastic cover layer 322 on the side where the through groove 324 of the first elastic cover layer 321 is located using the second injection molding, and forming the third elastic cover layer 316 on the side of the outer surface of the second earhook body 314 to wrap the elastic support component 323 and auxiliary wire, and to cover the outer surface of the second earhook housing 314; step 5) drawing out the auxiliary wire of the semi-finished product obtained in step 4) to form the inlet channel, and then threading the wire into the guide channel; step 6) fixing the first earhook body 312 to the second earhook body 314 obtained in step 5) using one or a combination of adhesive bonding, snap-in bonding, screwing, etc.

It should be noted that the acoustic device may include two earhook assemblies 300, respectively, the number of sound receiving nodes 340 may also be two, and the number of channel nodes may also be two. In particular, each of the accommodating spaces 360 of the earhook nodes 300 may be respectively located with the sound receiving node 340 and the channel node to improve the characteristics of the sound receiving node of each sound receiving node 340.

Figure 5 shows a diagram of the design of the first body behind the ear (figure 4). As shown in FIG. 5, the first earhook body 312 may include a bottom wall 3122 and a side wall 3124 annularly positioned around the bottom wall 3122. The second earhook body 314 may be closed by a side wall 3124 and positioned against the bottom wall 3122 to form accommodating space 360. In some embodiments, the accommodating slot 525 of the sound receiving assembly 340 may be located in the accommodating space 360. In some embodiments, the flange 3126 may protrude from the side of the bottom wall 3122 facing the second earhook body 314. The collar 3126 may surround the containing slot 525 to define and secure the sound receiving assembly 340. In some embodiments, at least a portion of the collar 3126 and the side wall 3124 may jointly define the containing slot 525.

In some embodiments, communication port 350 may be located in first earhook housing 312 located on sidewall 3124 at a location some distance from the speaker assembly (eg, position C in FIG. 4). In some embodiments, the communication hole 350 may also be located in the bottom wall 3122.

It should be noted that if the sound receiving node 340 communicates directly with the outside through the communication port 350, the sound path between the sound receiving node 340 and the outside (which may also be referred to as the sound receiving node 340 sound path for short) will be short. When the acoustic device is in a difficult environment (for example, when the airflow is relatively strong), the sound receiving unit 340 picks up more noise, thereby causing the "wind noise" phenomenon. The phenomenon of "wind noise" may refer to a phenomenon where the sound receiving unit 340 picks up outside noise and generates noise. Thus, according to some embodiments of the present disclosure, a channel node (e.g., channel node 600 shown in FIG. 6A) may be positioned between the sound receiving node 340 and communication port 350 to continue the sound path of the sound receiving node 340, thereby improving the performance of the sound receiving node 340. In some embodiments, the channel assembly may include a first opening (which may also be referred to as a sound inlet), a conduit, and a second opening (which may also be referred to as a sound outlet). In some embodiments, the channel assembly may be located in the containing space 360 and closed by the collar 3126. In other words, the channel assembly may be closed by the containing slot 525 and may press the sound receiving assembly 340 into the containing slot 525 and the sound inlet faces the side wall 3124 and butt-connected to the communication hole 350, the sound outlet is butt-connected to the sound-receiving node 340. With this arrangement, the channel node not only continues the sound path of the sound-receiving node, but also fixes the sound-receiving node. For more information regarding the channel node, you should refer to other places of this disclosure (for example, to figa and its description).

In some embodiments, the communication opening 350 may be a slot having a certain width (eg, 0.2 mm, 0.5 mm, 1 mm, etc.) in order to increase the contact area between the sound path of the sound receiving assembly 340 and the outside and improve the performance of the sound receiving assembly 340. In some embodiments, communication opening 350 may be in the form of a circle, square, ellipse, triangle, or the like. In some embodiments, in order to prevent deterioration of the waterproof and dustproof performance of the earhook housing 310 and/or the "wind noise" phenomenon caused by excessive contact area between the sound path of the sound receiving assembly 340 and the outside, the protective component 540 may be located in the path. sound passage of the sound receiver assembly 340. By way of example only, a protective component 540 may be positioned between the channel assembly and the earhook housing 310 in order to separate the communication port 350 from the sound inlet of the channel assembly, which is used to improve the windproof and sound deadening properties of the sound receiver assembly. 340 and improve the waterproof and dustproof performance of the earhook assembly 300. In some embodiments, the security component 540 may include one or more meshes, such as a first mesh 542 and a second mesh 544, which are layered. In some embodiments, one or more meshes may be made from different or the same material. In some embodiments, the first mesh 542 may be a metal mesh (eg, steel mesh, aluminum mesh) and the second mesh 544 may be a non-metal mesh (eg, nylon mesh, cotton mesh). In some embodiments, the second mesh 544 is located closer to the channel node than the first mesh 542. In some embodiments, the structural strength of the first mesh 542 may be greater than the structural strength of the second mesh 544. In some embodiments, the mesh number of the second mesh 544 may be greater than than the mesh number of the first mesh 542, with the combination of the two meshes allowing the protective component 540 to consider its own structural strength, the sound pickup requirements of the assembly 340, and the waterproof and dustproof requirements of the earhook assembly.

In some embodiments, a volume button hole 550 and/or a function button hole 555 may also be located in the first earhook housing 312. The volume control button may be located in the volume button hole 550 and extend through the volume button hole 550 so that the user can control the corresponding processing chip on the circuit board in the acoustic device by pressing/toggling the volume button and adjust the volume gain of the speaker assembly of the acoustic device. Likewise, the function button may be located in the function button hole 555 and extend through the function button hole 555, so that the user can control the corresponding processing chip on the acoustic device circuit board by pressing/toggling the function button and adjust the corresponding function of the acoustic device. In some embodiments, the function controlled by the function button may include power on/off control, pause/play control, wireless connection or data transfer control, and so on. or any combination of them.

On figa shows a diagram of the design of the channel node according to some variants of implementation of the present disclosure. FIG. 6B is a schematic diagram of the design of the sound receiving unit in FIG. 3. FIG. As shown in FIG. 6A, the channel assembly 600 may include a first port 610 (which may also be referred to as an audio inlet), a channel 620, and a second port 630 (which may also be referred to as an audio outlet). Sound inlet 610 and sound outlet 630 may be spaced and communicate with channel 620, respectively. The sound inlet 610 may be butt-connected to a communication port on the earhook assembly (eg, communication port 350 on the earhook assembly 300). The sound outlet 630 may be located adjacent to the sound receiver assembly 340 so that sound may be transmitted to the sound receiver assembly 340 in series through the communication hole, the sound inlet 610, the conduit 620, and the sound outlet 630.

In some embodiments, the shape of the sound inlet 610 may be the same or similar to the shape of the communication hole. For example, when the communication hole is a slit of a certain width, the sound inlet 610 can be made in the form of a slit. As another example, when the communication hole is in the shape of a round hole, the sound inlet 610 may be in the shape of an oval hole or a round hole.

In some embodiments, channel 620 may include a channel top wall 640, a channel bottom wall 650, and a channel side wall 660. The upper channel wall 640 and the lower channel wall 650 may be located at the two ends of the channel side wall 660, respectively. In particular, the upper channel wall 640 and the lower channel wall 650 may be located opposite each other, and the channel side wall 660 may be located between the upper channel wall 640 and the lower channel wall 650. In some embodiments, the length of the channel 620 in the direction connecting the upper channel wall 640 and the lower channel wall 650 may be in the range of 0.45 to 0.75 mm. For example, the length of the channel 620 in the direction connecting the upper channel wall 640 and the lower channel wall 650 may be 0.45 mm, 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm , 0.75mm, etc. In some embodiments, when channel assembly 600 is pressed against sound receiver assembly 340, in particular, channel bottom wall 650 may press sound receiver assembly 340. By way of example only, channel top wall 640 and channel bottom wall 650 are parallel and spaced apart from each other. each other, so the channel 620 is laid flat to adapt to the flat housing design.

In some embodiments, the sonic inlet 610 may be located in the side wall 660 or top wall 640 of the channel, and the sonic outlet 630 may be located in the bottom wall 650 of the channel. In some embodiments, the distance between sound inlet 610 and sound outlet 630 along channel 620 may be greater than or equal to 4 mm in order to continue the sound path of sound receiving assembly 340. For example, the distance between sound inlet 610 and sound outlet 630 along the channel 620 may have a diameter of 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 8 mm, 10 mm, and the like. In some embodiments, the channel assembly 600 may be a tubular structure with holes at both ends, consisting of only a side wall. An opening at one end of the tubular structure may be a sonic inlet and an opening at the other end of the tubular structure may be a sonic outlet.

In some embodiments, as shown in FIG. 6B, the sound pickup assembly 340 may include a sound pickup element 342 and a cover 344. The cover 344 may be fitted over the sound pickup element 342 around its outer periphery. In some embodiments, the shroud 344 may be positioned with the slot 346 facing the channel bottom wall 650 and the sound pickup element 342 is at least partially located in the slot 346. 600) presses the sound receiving assembly 340 into the accommodating slot 525 (i.e., the channel assembly 600 covers the sound receiving assembly 340), the protective cover 344 may abut against the side wall (e.g., bead 3126) of the accommodating slot 525 and fit snugly against the side wall of the accommodating slot 525, the slot 346 and the sound outlet 630 may be butt-jointed so that the sound picked up can enter the sound receiver member 342 through the sound outlet 630 and the slot 346. that between the protective cover 344 and the side wall of the containing groove 525 there is a force. Thus, the protective cover 344 and the side wall of the containing groove 525 can be intimately connected. In some embodiments, the shroud 344 may be resilient (e.g., a silicone shroud) so that the shroud 344 may be elastically deformed during assembly of the acoustic device, thereby enhancing the fixing effect of the side wall of the containing slot 525 on the sound receiving assembly 340 and improving the sealing efficiency of the path. between the sound receiving node 340 and the channel node 600, thereby improving the performance of the sound receiving node 340. 346, so that after the sound is transmitted to the groove 346, the sound cannot easily leak from the gap between the protective case 344 and the sound pickup element 342 to the rear side of the sound pickup element 342, thereby better maintaining the characteristics of the sound pickup element 342.

7 is a graph illustrating the relationship between the "howl" threshold and the position of the sound receiving assembly in an acoustic device according to some embodiments of the present disclosure. As shown in Fig. 7, the abscissa shows the position of the sound-receiving node (or communication hole corresponding to the sound-receiving node node) in the acoustic device, and the y-axis shows the howling thresholds of the sound-receiving node (the unit is dB). It should be noted that the higher the howling threshold of the sound receiving unit, the lower the probability of the sound receiving unit howling phenomenon, and the less the speaker unit affects the sound receiving unit.

In FIG. 7, positions O, B, C, D, E, F, G, H, and I indicate that the sound receiving nodes are located at positions O, B, C, D, E, F, G, H, and I in FIG. .2 or fig.4. The earhook assembly 300 shown in FIG. 4 may be an exemplary design of the earhook assemblies 212 and/or 214 of the acoustic device shown in FIG. As shown in FIGS. 2 and 4, when the acoustic device is in the wearing state, position O is on the outside of the earhook assembly 300 at some distance from the wearer's head. Positions B and E are located on the upper side of the earhook housing 310 of the earhook assembly 300, and position E is further away from the speaker assembly than position B. Position D is located on the underside of the earhook housing 310, and position C is located on the back of the housing 310 earhook some distance from the speaker assembly. In addition, for the rear bow assembly, when viewed together in FIG. 2, positions F, G, H, and I are, in turn, at some distance from speaker assembly 232 and/or 234. Position I may correspond to the middle position of the node 216 of the rear bow.

The howling threshold corresponding to position O can be used as a reference threshold, that is, the howling threshold for position O is set to 0. As shown in FIG. 7, the howling thresholds at positions B, C, D, E , F, G, H, and I are greater than 0, indicating that placing the sound receiving assembly at these positions is beneficial in reducing the "howling" phenomenon. In addition, the howling thresholds at positions F, G, H, and I are significantly higher than those at positions B, C, D, and E, indicating that this is more conducive to attenuating the “howling” phenomenon when the sound receiving unit is located on node of the back arch. It should be noted that for the earhook body, the "howl" thresholds in positions C and E are also significantly higher than in positions B and D, indicating that the farther the speaker assembly is located on the earhook body from the speaker assembly, the less degree, the phenomenon of "howling" is manifested. In position E, there may be structural interference between the earhook assembly and the rear earhook assembly, so it is preferable to install the sound pickup assembly in position C on the earhook assembly.

FIG. 8 is a block diagram illustrating an exemplary acoustic device according to some embodiments of the present disclosure. As shown in FIG. 8, acoustic device 800 may include multiple speaker nodes 810 (e.g., speaker nodes 810-1, 810-2), a control circuit node 820, and multiple interactive nodes 830 (e.g., interactive nodes 830-1, 830-2).

Speaker assembly 810 may be used to convert an audio signal (eg, an electrical signal) into a mechanical vibration signal. For example, speaker assembly 810 may receive audio from a microphone, cell phone, MP3 player, and so on. and convert it into a mechanical vibration signal, thereby producing sound. In some embodiments, speaker assembly 810 may include a bone conduction speaker, an air conduction speaker, and the like. or their combination. By way of example only, speaker assembly 810 may be a bone conduction speaker. A bone conduction speaker may include a magnetic circuit assembly, a vibration assembly, and a speaker housing. The magnetic core assembly can be used to create a magnetic field. When the vibration assembly receives an audio signal, the vibration assembly can convert the audio signal into a mechanical vibration signal under the action of a magnetic field. For example, the vibration assembly may include a voice coil and a vibration plate. The voice coil is located in the magnetic gap formed by the magnetic circuit assembly. The voice coil is vibrated by the magnetic field after the speaker assembly 810 receives an electrical signal (ie, an audio signal). The voice coil is physically connected to the vibration plate and transmits vibrations to the vibration plate. The speaker housing may include a vibration panel (i.e., a vibration transmission plate) facing the user's body. The speaker housing can accommodate a vibration assembly. In some embodiments, the vibrating assembly may be physically connected to the vibrating panel and vibrate the vibrating panel to transmit vibration to the user's auditory nerve through the user's head, thereby allowing the user to hear sound.

In some embodiments, multiple speaker nodes 810 may result in different resonant peaks. For example, multiple speaker nodes 810 may provide a resonant peak below 500 Hz, below 1000 Hz, or above 5000 Hz. In some embodiments, speaker assemblies 810 may include various types, such as electromagnetic (e.g., moving coil, moving core, etc.), piezoelectric, reverse piezoelectric, electrostatic, etc., which is not limited to the present disclosure. .

Control circuit node 820 may be used to control other nodes of acoustic device 800 (e.g., speaker nodes 810) to implement one or more functions of acoustic device 800. In some embodiments, control circuit node 820 may include multiple controls (e.g., controls 820-1, 820-2, etc.). Each control may respectively control at least one speaker node to independently control the speaker node, for example, independently control the audio gain of the corresponding speaker node. In some embodiments, the control circuit node 820 may further include one or more function buttons for controlling the acoustic device 800 on/off, pause/play, wireless connect/disconnect, and the like. For more information regarding the node of the control scheme, you should refer to other places of this disclosure (for example, to Fig.9 and its description).

Interactive node 830 may be used to provide interaction between the user and acoustic device 800. For example, interactive node 830 may be used to implement interaction between the user and speaker node 810 and control circuit node 820. In addition, the interactive unit 830 may initiate the control circuit unit 820 to control the acoustic device 800 to implement a function corresponding to the user's work instruction in response to receiving the user's work instruction. For example, the interactive node 830 may control the control circuit node 820 to power on/off the acoustic device 800 in response to receiving a press command from the user. As another example, each interactive node may correspond to a speaker node and its corresponding control. In addition, each interactive node can be used to trigger a control on the control circuit node 820 to control the corresponding speaker node 810 to implement a function corresponding to a user's work instruction in response to receiving the user's work instruction. For example, the interactive node 830-1 may operate the control 820-1 to increase or decrease the volume gain of the speaker node 810-1 in response to receiving a press or switch command from the user.

In some embodiments, the interactive node 830 may include one or more third holes located on the anchor node (e.g., the earhook node) of the acoustic device 800 and first components located in the third holes, respectively, and configured to trigger the node 820 control circuits (eg, a control element) for controlling one or more functions of the acoustic device 800. The first component may be used to receive an operating instruction from a user. In some embodiments, the user instruction may be embodied in the form of a force, a sound, or the like. For example, the user may generate a user work instruction by pressing a button, dialing a number, or the like. As another example, the first component may be a sound sensor, and the sound sensor may receive a user's voice to generate an operating instruction for the user. In some embodiments, the first component may include one or more buttons, such as a volume button and a function button. In some embodiments, the control circuit node 820 (eg, each control element) may include a second component. The second component may trigger the control circuit node 820 to implement functions corresponding to operation instructions, such as volume up/down, play/pause, power on/off, etc., in response to a user operation instruction (for example, in response to pressing , touch) received by the first component. In some embodiments, the second component may include a functional switch, such as a mechanical switch, a voice switch, or the like. For example, one side of the first component may be provided with an area to accommodate a switch. The switch location zone can be used to accommodate a function switch, so the first component can toggle the function switch upon receiving a user operating instruction (e.g., toggle), thereby actuating a control at control circuit node 820 to implement the corresponding function of the instruction.
