[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this application will not be described separately.

[0030] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0031] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more. In the description of this application, the orientation or positional relationship of "first direction," "second direction," and "height direction" is based on the accompanying drawings. Figure 1 , Figure 2 and Figure 8 The orientations or positional relationships shown are as follows: "first direction" is the direction indicated by arrow L1 in the figure; "second direction" is the direction indicated by arrow L2 in the figure; and "third direction" is the direction indicated by arrow L3 in the figure. It should be understood that these orientation terms are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application.

[0032] Wearable speaker devices in related technologies typically use external speakers to produce sound, resulting in limited sound quality and being less user-friendly for those with hearing impairments.

[0033] In view of this, refer to Figure 1 As shown, this application embodiment aims to provide a wearable speaker 10, including: a connector 11, two clamping arms 12 and at least two vibration devices 13.

[0034] The connector 11 extends along a first direction, and two clamping arms 12 are movably connected to the connector 11. The two clamping arms 12 are respectively disposed on opposite sides of the connector 11 along the first direction and extend along a second direction, the first direction and the second direction intersecting. At least two vibration devices 13 are respectively disposed on the two clamping arms 12. The vibration devices 13 are used to vibrate according to an audio signal, and at least a portion of the structure of the vibration devices 13 is exposed on the outer surface of the clamping arms 12.

[0035] Here, the first direction and the second direction can be perpendicular to each other or at any other suitable angle, without any restriction.

[0036] The connector 11 is mainly used to connect the two clamping arms 12 together. The specific structure of the connector 11 is not limited. As an example, the connector 11 can be roughly rod-shaped.

[0037] The extension of the connector 11 along the first direction specifically means that the connector 11 is extended or expanded in the first direction, and does not mean that the connector 11 is formed into a straight structure along the first direction. Taking the connector 11 as a rod-shaped structure as an example, the connector 11 can be a straight rod-shaped structure or an arc-shaped rod-shaped structure.

[0038] It is understandable that, since the first and second directions intersect, the two clamping arms 12 and the connector 11 will connect to form a roughly U-shaped structure. In actual use, the two clamping arms 12 can be clamped onto the user's body parts to achieve wear. As an example, in actual use, the two clamping arms 12 can rest against the user's two sides of the neck, two sides of the shoulders, two sides of the collarbone, and two sides of the chest, while the connector 11 can rest against the back of the user's neck, thus achieving wear around the user's neck. As another example, in actual use, the two clamping arms 12 can rest against the user's two sides of the temporal bones, while the connector 11 can rest against the user's parietal bone, occipital bone, and back of the neck, thus achieving wear around the user's head.

[0039] The specific structural form of the clamp arm 12 can be determined by those skilled in the art based on the actual desired wearing method, and there are no restrictions on it.

[0040] The specific way in which the clamping arm 12 and the connector 11 are connected is not limited. For example, it can be a sliding connection, a rotary connection, a combination of sliding connection and rotary connection, etc. A rotary connection can be a rotary connection with one degree of freedom or a rotary connection with multiple degrees of freedom, and the same applies to a sliding connection.

[0041] The specific structure of the vibration device 13 is not limited, as long as it can vibrate according to the audio signal. The specific number of vibration devices 13 is not limited. Only one vibration device 13 can be set on a clamping arm 12, or multiple vibration devices 13 can be set. The number of vibration devices 13 on two clamping arms 12 can be the same or different.

[0042] In this embodiment, a vibration device 13 is provided on the wearable speaker 10. It can be understood that bone conduction can transmit sound. When the vibration device 13 is attached to the user's body (e.g., attached to the user's temporal bone, clavicle, etc.), the user can hear the sound through bone conduction regardless of whether the user's hearing function is intact, which is more friendly to people with hearing impairment.

[0043] In addition to bone conduction, the vibration device 13 can also make users feel a certain vibration rhythm. In this way, users can not only get auditory effects, but also tactile effects, thus improving the user experience.

[0044] Furthermore, in this embodiment, the clamping arm 12 is movably connected to the connector 11. Thus, in actual use, the user can adjust the relative position of the clamping arm 12 and the connector 11 to make the part of the vibration device 13 exposed on the outer surface of the clamping arm 12 fit more closely to the user's skin, thereby improving the vibration transmission effect of the vibration device 13.

[0045] In addition, the movable connection between the clamping arm 12 and the connector 11 also helps the clamping arm 12 to better clamp the user's body parts, thereby improving the wearing comfort and stability of the wearable speaker 10.

[0046] It should be noted that in this embodiment, the vibration device 13 can be the only sound-generating structure of the wearable speaker 10, or the wearable speaker 10 can also include other sound-generating structures, such as an in-ear sound-generating structure, a speaker 16, etc.

[0047] In some embodiments, refer to Figure 1 and Figure 2 The vibration device 13 includes a vibration patch 131, which is exposed on one side surface of the clamping arm 12 along a third direction. The third direction is perpendicular to both the first and second directions.

[0048] In this embodiment, during actual use, the wearable speaker 10 can be worn around the user's neck, and the vibration patch 131 is exposed on the third-direction side surface of the clamp arm 12, so that the vibration patch 131 can fit against the user's chest or collarbone skin.

[0049] The advantage of this structure is that the neckband wearing method is more comfortable, and the skin of the chest or collarbone can withstand relatively strong vibrations. Setting the vibration patch 131 here helps to improve the tactile effect.

[0050] In some embodiments, as a supplement or alternative, the vibration patch 131 may also be exposed on the side surface of the clamping arm 12 facing the other clamping arm 12. Thus, in actual use, when the wearable speaker 10 is worn around the user's neck or head, the patch can conform to the user's neck skin or temporal bone skin.

[0051] In some embodiments, the vibration patch 131 includes a vibration plate 131a and a pad 131b. The vibration plate 131a is used to directly generate vibration, and the pad 131b covers the surface of the vibration plate 131a away from the clamping arm 12 and is exposed on the outer surface of the clamping arm 12.

[0052] In this embodiment, the vibration patch 131 is configured as a composite structure consisting of a vibration plate 131a and a pad 131b, rather than a one-piece structure. The vibration plate 131a is used to generate vibration, while the pad 131b is used to contact the user's skin. The two can be made of different materials, so as to obtain a better vibration effect and improve the user's wearing comfort.

[0053] As an example, the vibrating plate 131a can be made of a material with higher hardness and density to reduce the disturbance caused by the slight deformation of the vibrating plate 131a itself during vibration and improve the vibration effect; while the pad 131b can be made of a more skin-friendly material to improve the comfort of wearing the wearable speaker 10.

[0054] In some embodiments, the vibrating pad 131a can be a ceramic vibrating pad, and the pad 131b can be a flexible pad or a metal pad. The ceramic vibrating pad has a large amplitude and a wide adjustable range, which helps to further improve the vibration performance of the vibrating pad 131a. The metal pad or flexible pad has both high wearing comfort and good vibration transmission effect.

[0055] As an example, the materials for metal gaskets may include, but are not limited to, silver, copper, aluminum, stainless steel, etc., while the materials for flexible gaskets may include, but are not limited to, silicone and rubber.

[0056] In some embodiments, the vibrating pad 131a and the pad 131b are detachably connected, so that the user can connect the pad 131b of different materials to the vibrating pad 131a according to actual usage needs (for example, using a metal pad when the weather is hot, and a flexible pad when the weather is cold, etc.), or remove the pad 131b so that the vibrating pad 131a can be directly applied to the skin for use.

[0057] In some embodiments, refer to Figure 2 The vibration device 13 also includes a shock-absorbing connector 132 connected to the clamping arm 12, and a vibration patch 131 disposed on the side of the shock-absorbing connector 132 away from the clamping arm 12.

[0058] In this embodiment, the vibration patch 131 does not directly contact the clamping arm 12, but is connected to the clamping arm 12 through the shock-absorbing connector 132. The shock-absorbing connector 132 blocks the transmission of vibration from the vibration patch 131a to the clamping arm 12 to a certain extent, thereby further improving the user's wearing comfort.

[0059] The specific structural form of the shock-absorbing connector 132 is not limited.

[0060] In some embodiments, the shock-absorbing connector 132 is made of a flexible material. The flexible material may include, but is not limited to, silicone, rubber, ABS polymer, etc. This improves the shock absorption effect of the shock-absorbing connector 132. Furthermore, in actual use, the flexible shock-absorbing connector 132 can provide a certain elastic force, allowing the vibrating patch 131 to fit more tightly against the human skin, improving sound transmission and tactile feedback.

[0061] In some embodiments, refer to Figure 6 The damping connector 132 forms a damping cavity 132e inside. In this way, the damping cavity 132e can provide space for the cable routing of the vibration device 13, and can also further increase the vibration absorption capacity of the damping connector 132.

[0062] In some embodiments, refer to Figure 1 , Figure 3 , Figure 5 and Figure 6 The clamping arm 12 forms a mounting cavity 12a. The shock-absorbing connector 132 includes a first connecting part 132a and a second connecting part 132b. The first connecting part 132a is disposed in the mounting cavity 12a, and the second connecting part 132b protrudes from one side surface of the clamping arm 12.

[0063] Taking the damping patch exposed on one side surface of the clamping arm 12 along the third direction as an example, the second connecting part 132b protrudes from one side surface of the clamping arm 12 along the third direction. The mounting cavity 12a is a recess formed on one side surface of the clamping arm 12 along the third direction. Understandably, the thickness of the clamping arm 12 at the mounting cavity 12a is thinner than the thickness at other locations of the clamping arm 12.

[0064] Thus, placing the shock-absorbing connector 132 within the mounting cavity 12a provides additional installation space for the shock-absorbing connector 132, reducing the thickness of the wearable speaker 10 at the location of the shock-absorbing connector 132, thereby achieving a thinner and lighter design for the wearable speaker 10.

[0065] In some embodiments, at least one protrusion is formed on the first connecting portion 132a, and a slot is formed on one side surface of the clamping arm 12, so that the protrusion of the first connecting portion 132a can be engaged with the slot. This facilitates the installation and connection of the shock-absorbing connector 132 on the clamping arm 12.

[0066] In some embodiments, in a projection plane perpendicular to the first connecting portion 132a and the second connecting portion 132b, the projection of the second connecting portion 132b covers and extends beyond the projection of the first connecting portion 132a.

[0067] Taking the vibration patch 131 exposed on one side of the housing along the third direction as an example, in the projection plane perpendicular to the third direction, the projection of the second connection 132b covers and exceeds the projection of the first connection 132a.

[0068] Specifically, the second connecting part 132b is an annular fan blade extending laterally away from the first connecting part 132a, so that the shock-absorbing connecting member 132 as a whole forms a trumpet-shaped structure.

[0069] Thus, a larger vibration patch 131 can be installed on the second connection 132b, thereby providing a larger contact surface to achieve better vibration transmission and further improve wearing comfort.

[0070] In some embodiments, refer to Figure 5 and Figure 6 Taking the vibration patch 131 exposed on one side of the housing along the third direction as an example, the clamping arm 12 includes a first housing 121 and a second housing 122, the first housing 121 and the second housing 122 are connected along the third direction, and the mounting cavity 12a is formed in the second housing 122.

[0071] In this way, when assembling the wearable speaker 10, the components located inside the clamping arm 12 can be installed on the second housing 122 first, and then the first housing 121 can be installed; at the same time, when it is necessary to adjust the internal components, the first housing 121 can be disassembled first for adjustment, thus improving assembly and maintenance efficiency.

[0072] In some embodiments, the first housing 121 has a first connection hole 121a, the second housing 122 has a second connection hole 122a, and the shock-absorbing connector 132 has a third connection hole 132c. The first connection hole 121a, the second connection hole 122a, and the third connection hole 132c all extend in a third direction and communicate with each other. The wearable speaker 10 also includes a fastener, which passes through the first connection hole 121a, the second connection hole 122a, and the third connection hole 132c to fix the shock-absorbing connector 132, the first housing 121, and the second housing 122 together.

[0073] Specifically, there may be more than one first connecting hole 121a, and the same applies to the second connecting hole 122a or the third connecting hole 132c; the fastener may be a screw, and the first connecting hole 121a may have threads to match the threads on the fastener for fixing; while the diameter of the second connecting hole 122a and the third connecting hole 132c is larger than that of the first connecting hole 121a, matching the size of the fastener nut.

[0074] The coaxial design of the first connecting hole 121a, the second connecting hole 122a and the third connecting hole 132c enables the fixed connection of the first housing 121, the second housing 122 and the shock-absorbing connector 132 with fewer fasteners, reducing manufacturing costs and improving assembly efficiency.

[0075] In some embodiments, refer to Figure 1 The vibration device 13 is located on the side of the clamp arm 12 away from the connector 11. On the one hand, by placing it at the end of the clamp arm 12, the vibration device 13 can reduce the vibration of the wearable speaker 10 as a whole; on the other hand, it also leaves enough space for the part of the clamp arm 12 that is close to the connector 11.

[0076] In some embodiments, refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 The vibration device 13 also includes a circuit board 133, which can convert an electrical signal containing sound information into an audio signal and transmit it to the vibrating patch 131, so that the vibrating patch 131 can output vibration according to the audio signal. A cavity 12b is formed between the first housing 121 and the second housing 122, and the circuit board 133 is disposed in the cavity 12b and electrically connected to the vibrating patch 131a.

[0077] Thus, the cavity 12b can greatly reduce the weight of the clamping arm 12, achieving a lightweight design for the wearable speaker 10, and also provide space for the circuit board 133 or cables of the wearable speaker 10. At the same time, separating the vibration component and control component of the vibration device 13 can effectively reduce the negative impact of vibration on the control component.

[0078] In some embodiments, refer to Figure 1 , Figure 5 and Figure 6 The vibration device 13 also includes a cable (not shown in the figure); a wire hole 132d is formed on the shock-absorbing connector 132; the cable passes through the wire hole 132d and its two ends are respectively connected to the circuit board 133 and the vibrating plate 131a. This provides a channel for signal transmission.

[0079] In some embodiments, refer to Figure 5 and Figure 6 The first housing 121 has at least one first fixing post 121b disposed toward the second housing 122, and a first connecting hole 121a is formed in the first fixing post 121b. The second housing 122 has at least one second fixing post 122b disposed toward the first housing 121, and a second connecting hole 122a is formed in the second fixing post 122b. The first fixing post 121b and the second fixing post 122b are connected in a one-to-one correspondence. The circuit board 133 forms at least one fixing hole 133a, and the second fixing post 122b passes through the fixing hole 133a.

[0080] Specifically, the inner diameter of the second connecting hole 122a matches the outer diameter of the first fixing post 121b, and the first fixing post 121b can be inserted into the second connecting hole 122a. In another embodiment, the second fixing post 122b can also be inserted into the first connecting hole 121a in a similar manner.

[0081] Thus, on the one hand, the first fixing post 121b and the second fixing post 122b can provide necessary support inside the cavity 12b, reducing the possibility of deformation of the first housing 121 and the second housing 122 due to external forces; on the other hand, the cooperation between the second fixing post 122b and the fixing hole 133a can provide fixation for the circuit board 133.

[0082] Understandably, referring to Figure 1 and Figure 7 Within the cavity 12b, along the extension direction of the clamping arm 12, there can be multiple corresponding first fixing posts 121b and second fixing posts 122b. These first fixing posts 121b and second fixing posts 122b are divided into two parts. One part, as described above, fixes the vibration device 13. The other part of the first fixing posts 121b and second fixing posts 122b are distributed along the direction away from the vibration device 13 inside the cavity 12b. These fixing posts do not undertake the task of fixing the vibration device 13, but provide necessary support for the middle section of the clamping arm 12.

[0083] In some embodiments, the wearable speaker 10 further includes a retractable telescopic member (not shown) extending along a first direction, with both ends of the telescopic member connected to one of the clamping arms 12 and the connector 11, respectively, so that the distance between the two clamping arms 12 along the first direction can be adjusted according to the user's needs.

[0084] In some embodiments, refer to Figure 1 The vibration device 13 is exposed on one side of the clamping arm 12 along a third direction. The clamping arm 12 is rotatably connected to the connector 11, and the axis of rotation is parallel to the first direction. In this way, the user can rotate the clamping arm 12 to make the vibration device 13 fit more closely to the user's collarbone or chest skin.

[0085] In some embodiments, refer to Figure 2 and Figure 3 The wearable speaker 10 includes two rotating shafts 15, which are rotatably connected to the connector 11 respectively. The end of the clamping arm 12 near the connector 11 is bent toward the connector 11 to form a transition section 123. The transition section 123 is connected to the corresponding rotating shaft 15 and forms an anti-rotation fit, thereby realizing the rotatable connection between the two clamping arms 12 and the connector 11.

[0086] Specifically, to improve the wearing comfort of the wearable speaker 10, the bending of the clamping arm 12 has a certain curvature, so that the two clamping arms 12 and the connector 11 form a U-shape that is easy to carry. The pivot 15 can be embedded inside the clamping arm 12 and the connector 11. The anti-rotation engagement between the pivot 15 and the transition section 123 can be achieved by fixing the pivot 15 to the transition section 123. The fixing method includes, but is not limited to, welding, snap-fit ​​connection or riveting.

[0087] In this way, the pivot 15 can withstand the bending moment and torque generated by the movement between the clamping arm 12 and the connector 11, reducing the stress on the clamping arm 12 and the connector 11. Furthermore, lighter materials can be used to make the clamping arm 12 and the connector 11, further improving the comfort of the wearable speaker 10.

[0088] It should be noted that the rotational connection between the clamping arm 12 and the connecting member 11 is not limited to this method.

[0089] In some embodiments, refer to Figure 8 and Figure 9 The rotating shaft 15 extends along the first direction, and an annular groove 15a is formed on the circumferential surface of the rotating shaft 15. The connector 11 has a first connecting cavity 11a formed at both ends along the first direction. A part of the rotating shaft 15 is located in the first connecting cavity 11a. A limiting block 111 is formed inside the first connecting cavity 11a. The limiting block 111 is located in the annular groove 15a and slides with the annular groove 15a.

[0090] Understandably, an annular groove 15a may be formed on the inner surface of the first connecting cavity 11a, and a limiting block 111 may be formed on the circumferential surface of the rotating shaft 15.

[0091] Thus, by setting the limiting block 111 in the annular groove 15a, the rotating shaft 15 can be prevented from dislodging from the first connecting cavity 11a, thereby reducing the possibility of the rotating shaft 15 and the clamping arm 12 disengaging from the connecting member 11. The sliding fit between the annular groove 15a and the limiting block 111 also effectively reduces the friction generated when the clamping arm 12 rotates relative to the connecting member 11.

[0092] In some embodiments, refer to Figure 8 , Figure 9 and Figure 10The rotating shaft 15 has a positioning hole 15b that extends radially along the rotating shaft 15. A second connecting cavity 123a is formed on one end of the transition section 123 that is connected to the rotating shaft 15. A portion of the rotating shaft 15 is located in the second connecting cavity 123a. A positioning post 123b is formed inside the second connecting cavity 123a and is located in the positioning hole 15b.

[0093] In some embodiments, refer to Figure 8 , Figure 9 and Figure 10 The second connecting cavity 123a also has a positioning rib 123c formed inside. The positioning rib 123c is formed between the positioning post 123b and the inner wall surface of the second connecting cavity 123a to strengthen the positioning post 123b. Understandably, the rotating shaft 15 also has a positioning groove 15c that matches the positioning rib 123c.

[0094] Thus, by designing the positioning post 123b and the positioning rib 123c, the anti-rotation fit between the rotating shaft 15 and the transition section 123 is achieved, and the movement between the rotating shaft 15 and the transition section 123 in the first direction is also prevented, reducing the possibility of the rotating shaft 15 and the connecting piece 11 disengaging from the transition section 123 of the clamping arm 12.

[0095] In some embodiments, refer to Figure 8 The rotating shaft 15 has a first wiring hole 15d, which passes through the rotating shaft 15 along a first direction.

[0096] Thus, combined Figure 1 The signal line, power line or control line of the wearable speaker 10 can be connected to the cavity 12b inside the connector 11 and the clamp arm 12 through the first wiring hole 15d.

[0097] In some embodiments, refer to Figure 1 and Figure 2 The wearable speaker 10 also includes at least two speakers 16, which are respectively disposed on two clamping arms 12, and the speakers 16 are used to emit sound according to the audio signal.

[0098] Thus, by simultaneously setting up the speaker 16 and the vibration device 13, the wearable speaker 10 can control the speaker 16 to emit sound and transmit it to the ear on the one hand, and control the amplitude and frequency of the vibration device 13 to contact the human body, so that the human body can feel the rhythmic vibration of the sound, thereby forming a compound rhythm with the sound and optimizing the experience.

[0099] In some embodiments, refer to Figure 2The speaker 16 is positioned on the side of the clamp arm 12 closest to the connector 11. Thus, when the wearable speaker 10 is worn around the user's neck, the side of the clamp arm 12 closest to the connector 11 is closer to the ear, resulting in a better listening experience when the speaker 16 is positioned there.

[0100] In some embodiments, refer to Figure 2 and Figure 3 The vibration device 13 is exposed on one side of the clamping arm 12 along a third direction, and the other side of the clamping arm 12 along a third direction forms a sound-emitting hole 12c. The speaker 16 is positioned at the corresponding sound-emitting hole 12c. The sound-emitting hole 12c reduces the obstruction to sound transmission by the speaker 16. At the same time, by reasonably setting the number and direction of the sound-emitting holes 12c, the direction of sound transmission can be made more directional, and the high-frequency cutoff frequency and mid-low frequency sensitivity can be effectively controlled, thereby reducing noise.

[0101] In some embodiments, the vibration device 13 and the sound-emitting hole 12c are offset from each other along a second direction. For example, the vibration device 13 is located at the end of the clamping arm 12 away from the connector 11, and the sound-emitting hole 12c is located at the end of the clamping arm 12 near the connector 11. This helps to bring the sound-emitting hole 12c closer to the human ear and improve the auditory experience.

[0102] In some embodiments, refer to Figure 1 and Figure 2 The wearable speaker 10 also includes a battery assembly 17, which is connected to the connector 11 and located between the two clamping arms. The battery assembly 17 is used to power the wearable speaker.

[0103] In some embodiments, the battery assembly 17 includes a battery case 171 and a battery 172, the battery 172 being disposed within the battery case 171 and capable of powering the speaker 16 and the vibration device 13.

[0104] In some embodiments, the wearable speaker 10 further includes an adapter 14 that connects the battery compartment 171 and the connector 11. The battery 172 can be electrically connected to components such as the speaker 16 and the vibration device 13 via the adapter 14. Specifically, see... Figure 9 and Figure 10 The two first connecting cavities 11a are interconnected. A second wiring hole 14a is formed inside the adapter 14, which runs through the adapter 14 in a third direction. The second wiring hole 14a is also interconnected with the two first connecting cavities 11a, so that the power line of the battery 172 (not shown in the figure) can first pass through the second wiring hole 14a and split into two paths to enter the two second connecting cavities 123a respectively, and then pass through the first wiring hole 15d to enter the cavity 12b, and then connect to the speaker 16 and the vibration device 13 respectively.

[0105] In some embodiments, the battery 172 is detachably disposed within the battery case 171. This detachable battery 172 allows for greater flexibility in the power supply method of the wearable speaker 10. It is understood that the detachable placement of the battery 172 within the battery case 171 does not mean that charging is only possible after the battery 172 is removed; the battery 172 can be charged even when it is installed within the battery case 171. Furthermore, the weight of the battery assembly 17 helps to balance the weight of the clamping arm 12 and the vibration device 13, reducing the possibility of the wearable speaker 10 tilting forward and becoming unbalanced.

[0106] It should be noted that the battery assembly 17 is not limited to this arrangement. For example, the battery assembly 17 can also be disposed inside the clamping arm 12 or the connector 11. In some embodiments, the battery case 171 is rotatably connected to the connector 11, with the axis of rotation parallel to a first direction. Thus, during actual wear, the user can adjust the battery case 171 to a comfortable angle. As mentioned above, the battery case 171 is connected to the connector 11 via an adapter 14. In this embodiment, the battery case 171 can be rotatably connected to the adapter 14, or the adapter 14 can be rotatably connected to the connector 11.

[0107] In some embodiments, refer to Figure 2 The battery assembly 17 includes a cover 173, and the battery case 171 has an opening on the side opposite to the clamping arm 12. The cover 173 is detachably connected to the battery case 171 to cover the opening. Thus, the user can easily remove the battery 172 simply by opening the cover 173. The cover 173 also serves to protect the internal components of the battery case 171.

[0108] In some embodiments, the battery assembly 17 includes a magnetic element that connects the cover 173 and the battery compartment 171. Thus, the magnetic element can generate an attractive force to secure the connection between the cover 173 and the battery compartment 171, and can also release this connection when the user needs to open the battery compartment 171.

[0109] In some embodiments, refer to Figure 2 The wearable speaker 10 includes a support pad 174 disposed on the surface of the battery compartment 171 facing the clamp arm 12. When wearing the wearable speaker 10, the support pad 174 provides support for the human body, increasing wearing comfort.

[0110] It should be noted that in some other embodiments, the support pad 174 may also be directly disposed on the connector 11.

[0111] In some embodiments, refer to Figure 11The wearable speaker 10 includes a signal transmitter 18 electrically connected to the speaker 16 and the vibration device 13. The signal transmitter 18 is configured to synchronously transmit audio signals to the speaker 16 and the vibration device 13. Thus, when the speaker 16 outputs sound according to the audio signal, the vibration device 13 can synchronously output a vibration signal according to the audio signal, thereby enabling the user to simultaneously perceive sound and rhythm through multiple sensory pathways, obtaining a composite experience where sound and rhythm are matched.

[0112] In some embodiments, refer to Figure 11 The wearable speaker 10 also includes a signal receiver 19, which is electrically connected to the signal transmitter 18. The audio signal receiver 19 is used to receive external electrical signals and input the electrical signals to the signal transmitter 18. The signal transmitter 18 is used to generate audio signals based on the electrical signals.

[0113] In this way, the signal receiver 19 establishes a signal transmission channel with the external device of the wearable speaker 10. This signal transmission channel can be wired, which can reduce interference that may occur during transmission.

[0114] In some embodiments, refer to Figure 11 The signal receiver 19 includes a Bluetooth receiver 191 for receiving electrical signals via the Bluetooth protocol.

[0115] In some embodiments, refer to Figure 11 The signal receiver 19 includes a wireless network receiver 192 for receiving electrical signals via a wireless network protocol.

[0116] Specifically, the Bluetooth receiver 191 and / or the wireless network receiver 192 can establish a wireless connection with external devices such as mobile phones or computers, enabling the wearable speaker 10 to receive electrical signals even when it is a certain distance away from the external device.

[0117] In some embodiments, the signal receiver 19 may also receive electrical signals via a wired connection.

[0118] In some embodiments, the signal transmitter 18 may be directly electrically connected to a device for emitting audio signals.

[0119] In some embodiments, refer to Figure 11 The audio signal includes a first audio signal for transmission to the speaker 16 and a second audio signal for transmission to the vibration device 13. The signal transmitter 18 includes a decoder 181 for decoding the received electrical signal into the first audio signal and the second audio signal.

[0120] In this embodiment, the first audio signal and the second audio signal obtained by the decoder 181 can be completely identical audio signals or not completely identical audio signals. For example, the low frequency of one of the first audio signal and the second audio signal can be significantly higher than the low frequency of the other, so as to better utilize the sound performance of the speaker 16 and the vibration device 13 and improve the user experience.

[0121] In some embodiments, the wearable speaker 10 also includes an indicator light disposed on the clamp arm 12, and the indicator light is electrically connected to at least one of the vibration device 13, the speaker 16, the signal transmitter 18, and the signal receiver 19.

[0122] Specifically, this application does not limit the form or location of the indicator light. In one embodiment, the indicator light can be a monochrome LED light, which is constantly lit when at least one of the vibration device 13, speaker 16, signal transmitter 18, and signal receiver 19 is working normally, and turns off when at least one of the vibration device 13, speaker 16, signal transmitter 18, and signal receiver 19 is not working normally. In another embodiment, the indicator light can be a liquid crystal display screen, which can display the specific working information of at least one of the vibration device 13, speaker 16, signal transmitter 18, and signal receiver 19. In some embodiments, the wearable speaker 10 also includes a voltage regulator, the input of which is connected to the battery assembly 17, and the output of which is connected to at least one of the vibration device 13, speaker 16, signal receiver 19, and signal transmitter 18, for adjusting the voltage output by the battery assembly 17 to be adapted to the rated working voltage of any one of the vibration device 13, speaker 16, signal receiver 19, and signal transmitter 18, thereby realizing the working state of the wearable speaker 10.

[0123] In some embodiments, the wearable speaker 10 further includes a control button connected to the signal receiver 19, which is used to send control signals to at least one of the signal transmitter 18, the signal receiver 19, the speaker 16, and the vibration device 13. The specific location and structure of the control button are not limited.

[0124] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
