[0023] Figure 1 This is an exemplary structural diagram of an audio alarm clock according to some embodiments of this specification. Figure 2 This is an exemplary structural diagram of the knob and baffle shown according to some embodiments of this specification.

[0024] In some embodiments, such as Figure 1 and Figure 2 As shown, the audio alarm clock 100 may include a housing 110 and a rotatable knob 120. The knob 120 includes a plurality of teeth that are evenly distributed along the circumference of the knob 120, and a tooth groove 121 is formed between two adjacent teeth. The housing 110 is provided with at least one baffle 130, which is located between the housing 110 and the knob 120. One end of the baffle 130 is connected to the housing 110, and the other end is bent toward the knob 120. At least a portion of the baffle 130 can be engaged in the tooth groove 121.

[0025] An audio alarm clock 100 refers to an alarm clock integrated into an audio system, enabling the system to function as both an audio device and an alarm clock. The audio function outputs sound, such as playing music. The alarm clock function displays the time and rings at set times. It is understood that the alarm clock integrated into the audio system should not interfere with the system's functionality and should be able to operate silently. In some embodiments, the audio alarm clock 100 may be a quartz clock, providing accurate and stable timekeeping without affecting the audio function. In some embodiments, the user can set the timer and alarm sound of the audio alarm clock 100.

[0026] In some embodiments, the audio alarm clock 100 can be used in a home or office setting, such as a bedroom or hotel.

[0027] The housing 110 is a structure that forms a space to accommodate the internal components of the audio alarm clock 100, preventing the audio alarm clock 100 from being affected or damaged by the external environment. The audio alarm clock 100 may include a movement, a dial, and other structures. The movement is the core part of the alarm clock, responsible for timekeeping and the alarm's timing function. The dial can display the current time through hour, minute, and second hands (or numbers). The housing 110 can fit snugly against the dial. In some embodiments, the dial can be various shapes such as round, square, oval, or irregular.

[0028] The housing 110 may have a mounting space that matches the shape of the dial, and the dial may be fitted into the mounting space. For example, for a round dial, the housing 110 may have a round hole of a matching size, and the round dial may be fitted into the hole.

[0029] In some embodiments, the housing 110 may be made of materials such as plastic, aluminum profile, sheet metal, or stainless steel.

[0030] In some embodiments, the housing 110 may be disposed within the housing of the speaker, so that the speaker alarm clock 100 and the speaker become a single unit.

[0031] The knob 120 is used to adjust the alarm clock or time of the audio alarm clock 100. In some embodiments, the knob 120 has a disc-shaped or ring-shaped structure.

[0032] In some embodiments, the material of the knob 120 may be the same as or different from that of the housing 110.

[0033] In some embodiments, the projection of the knob 120 along a first direction is located in the projection of the housing 110 along the first direction. The first direction is a direction perpendicular to the dial of the audio alarm clock 100, for example, Figure 1 The direction perpendicular to the paper. The projection of knob 120 along the first direction is located within the projection of housing 110 along the first direction, indicating that knob 120 is located within the area covered by housing 110 along the first direction. In some embodiments, the aforementioned projection along the first direction refers to the projection of the outer contours of knob 120 and housing 110, and the center positions of knob 120 and housing 110 can be hollow. For example, if both knob 120 and housing 110 are annular, then knob 120 is located within the area covered by the outer contour of housing 110 along the first direction.

[0034] In some embodiments, the size of the knob 120 may be greater than or equal to the size of the dial, and the size of the housing 110 may be greater than or equal to the size of the knob. For example, as... Figure 1 As shown, the dial is circular, the knob 120 is circular with a diameter larger than the dial, and the housing 110 is annular, with an outer diameter larger than the diameter of the knob 120. For example, as... Figure 2 As shown, the dial is circular, the knob 120 is circular with a diameter equal to that of the dial, and the housing 110 is annular with an outer diameter equal to that of the knob 120.

[0035] In some embodiments, such as Figure 2 As shown, the knob 120 may include multiple teeth, which are evenly distributed along the circumference of the knob, and a tooth groove 121 is formed between two adjacent teeth.

[0036] In some embodiments, multiple teeth of the knob 120 may be provided along the edge of the knob 120, that is, multiple teeth protrude from the edge of the knob 120, so that the knob 120 forms a gear shape.

[0037] In some embodiments, multiple teeth of the knob 120 may be provided on the surface of the knob 120, that is, multiple teeth protrude from the upper or lower surface of the knob 120 and are evenly distributed along the circumference of the knob 120, see [reference]. Figure 2 .

[0038] In some embodiments, the tooth groove 121 may include straight tooth grooves, oblique tooth grooves, curved tooth grooves, etc. In some embodiments, the number of tooth grooves 121 is related to the number of teeth; the greater the distance between two teeth, the more tooth grooves there are.

[0039] In some embodiments, the depth of the tooth groove 121 is 0.3mm to 5mm, and the width of the tooth groove 121 is 0.3mm to 5mm. In some embodiments, the depth of the tooth groove 121 is 0.3mm to 4mm, and the width of the tooth groove 121 is 0.3mm to 4mm. In some embodiments, the depth of the tooth groove 121 is 0.5mm to 3mm, and the width of the tooth groove 121 is 0.5mm to 3mm. In some embodiments, the depth of the tooth groove 121 is 1mm to 2mm, and the width of the tooth groove 121 is 1mm to 2mm. In some embodiments, the depth of the tooth groove 121 is 0.5mm, and the width of the tooth groove 121 is 0.5mm. In some embodiments, the number of tooth grooves 121 can be 90 to 360. In some embodiments, the number of tooth grooves 121 can be 100 to 300. In some embodiments, the number of tooth grooves 121 can be 150 to 240. In some embodiments, the number of tooth grooves 121 can be 200 to 300. In some embodiments, the number of grooves 121 can be 320.

[0040] By setting the appropriate depth and width of the grooves, and by setting the appropriate number of grooves, the feel of rotating the knob can be improved, thus enhancing the user experience.

[0041] The baffle 130 can mate with the toothed groove to secure the knob. In some embodiments, such as Figure 2 As shown, the baffle 130 is located between the housing 110 and the knob 120. One end of the baffle 130 is connected to the housing 110, and the other end is bent toward the knob 120. At least a portion of the baffle 130 can be engaged in the toothed groove 121.

[0042] The baffle 130 is a curved sheet-like structure. In some embodiments, the baffle 130 has a certain degree of elasticity and stiffness, and can deform under stress (e.g., by further increasing the bending angle), and can automatically return to its original shape when the stress is removed. In some embodiments, the baffle 130 can be made of metal, such as stainless steel or aluminum alloy.

[0043] In some embodiments, at least a portion of the baffle 130 can engage in the toothed groove 121, and the structure formed by the engagement of the baffle 130 and the toothed groove 121 allows the knob 120 to be rotated only in one direction. For example, as... Figure 2 As shown, the right end of the baffle 130 is bent toward the knob 120. When the knob is turned to attempt to rotate it in the A direction, the teeth of the knob 120 exert a force to the right and away from the knob 120 on the baffle 130. The baffle 130 deforms and disengages from the tooth groove 121, thus allowing the knob 120 to rotate in the A direction. When the knob is turned to attempt to rotate it in the opposite direction of the A direction, the tooth groove 121 of the knob 120 exerts a force to the left and away from the knob 120 on the baffle 130. The baffle 130 deforms, but due to the restriction of the tooth groove 121, the baffle 130 cannot disengage from the tooth groove 121, and therefore the knob 120 cannot rotate in the opposite direction of the A direction.

[0044] By designing the baffle and knob appropriately, the knob can only rotate counterclockwise in one direction to adjust the alarm clock. When the knob is rotated, the teeth and baffle bounce elastically, providing a good tactile feel and improving the user experience.

[0045] In some embodiments, such as Figure 2 As shown, the housing 110 has at least one groove 111 on the side facing the knob 120, and the baffle 130 is disposed in the groove 111 and is set at an angle relative to the bottom wall of the groove 111.

[0046] In some embodiments, one end of the baffle 130 can be fixed to the bottom wall of the groove 111 by means of connection such as welded connection, threaded connection, or riveted connection. Among them, the welded connection can include fusion welding, pressure welding, brazing, etc.

[0047] Figure 3 This is an exemplary structural diagram of the baffle shown according to some embodiments of this specification.

[0048] In some embodiments, such as Figure 3 As shown, the baffle 130 includes a fixing part 131 and a bending part 132. One end of the bending part 132 is fixedly connected to the fixing part 131. The fixed connection includes, but is not limited to, welding, snap-fitting, and integral molding. The fixing part 131 is fixed to the bottom wall of the groove 111 by screws 133. The bending part 132 is bent at a certain angle relative to the bottom wall of the groove 111. The other end of the bending part 132 is used to engage in the toothed groove 121.

[0049] In some embodiments, the thickness of the baffle 130 is 0.1mm to 1mm, the width of the baffle 130 is 1mm to 10mm, and the angle between the baffle 130 and the bottom wall of the groove 111 is 20° to 90°. In some embodiments, the thickness of the baffle 130 is 0.2mm to 0.8mm, the width of the baffle 130 is 2mm to 8mm, and the angle between the baffle 130 and the bottom wall of the groove 111 is 30° to 80°. In some embodiments, the thickness of the baffle 130 is 0.4mm to 0.6mm, the width of the baffle 130 is 4mm to 7mm, and the angle between the baffle 130 and the bottom wall of the groove 111 is 40° to 70°. In some embodiments, the thickness of the baffle 130 is 0.3mm to 0.7mm, the width of the baffle 130 is 4mm to 6mm, and the angle between the baffle 130 and the bottom wall of the groove 111 is 50° to 60°. In some embodiments, the thickness of the baffle 130 is 0.2 mm, the width of the baffle 130 is 2 mm, and the angle between the baffle 130 and the bottom wall of the groove 111 is 27°. For example... Figure 3 As shown, the angle between the baffle 130 and the bottom wall of the groove 111 is the angle α between the bent part 132 and the bottom wall.

[0050] If the baffle is too thin, it may not be able to withstand the applied force, bend excessively, or even break. If the baffle is too thick, it may be difficult to bend to the required angle, making it difficult to rotate the knob or resulting in a stiff rotation feel. Therefore, by properly setting the size of the baffle and the angle between the baffle and the bottom wall of the groove, the feel of rotating the knob can be improved, the durability of the baffle can be increased, and its service life can be extended.

[0051] In some embodiments, the width and length of the baffle 130 need to be smaller than the width and length of the groove 111 so that the baffle 130 can be installed in the groove 111. The bent portion 132 of the baffle 130 can extend beyond the depth of the groove 111 and engage in the toothed groove 121.

[0052] In some embodiments, the number of baffles 130 is 3 to 8. In some embodiments, the number of baffles 130 is 3 to 5. In some embodiments, the number of baffles 130 is 4 to 7. In some embodiments, the number of baffles 130 is 4. In some embodiments, the multiple baffles 130 can be evenly distributed.

[0053] Too many baffles may affect the smoothness of the knob rotation, while too few baffles may affect the stability of the knob when it is fixed. By setting the number of baffles appropriately, the feel of rotating the knob and the stability of adjustment can be improved.

[0054] In some embodiments of this specification, by reasonably designing the thickness, width, and local bending angle of the baffle, and combining it with the size of the groove, the knob can be rotated in one direction, has a good feel, and is also highly durable.

[0055] In some embodiments, such as Figure 3 As shown, each toothed groove 121 of the knob 120 includes a first sidewall 1211 and a second sidewall 1212. In some embodiments, the first sidewall 1211 and the second sidewall 1212 are distributed sequentially along the rotation direction of the knob 120. For example, when the knob 120 rotates along direction A, for any toothed groove 121, the first sidewall 1211 and the second sidewall 1212 are sequentially included along direction A.

[0056] In some embodiments, the angle between the first sidewall 1211 and the bottom wall of the groove 111 may be smaller than the angle between the second sidewall 1212 and the bottom wall of the groove 111. In some embodiments, the angle between the first sidewall 1211 and the bottom wall of the groove 111 is 20°~90°, and the angle between the second sidewall 1212 and the bottom wall of the groove 111 is 60°~90°. In some embodiments, the angle between the first sidewall 1211 and the bottom wall of the groove 111 is 30°~80°, and the angle between the second sidewall 1212 and the bottom wall of the groove 111 is 75°~90°. In some embodiments, the angle between the first sidewall 1211 and the bottom wall of the groove 111 is 40°~70°, and the angle between the second sidewall 1212 and the bottom wall of the groove 111 is 80°~88°.

[0057] In some embodiments of this specification, by setting the included angles of the first and second sidewalls relative to the bottom wall of the groove, the baffle can be better fitted with the toothed groove. A smaller angle between the first sidewall and the bottom wall of the groove allows the baffle to be accommodated in the toothed groove, while also allowing it to easily disengage from the groove when the knob is rotated. A larger angle between the second sidewall and the bottom wall of the groove prevents the baffle from sliding out of the toothed groove when the knob is rotated in the opposite direction.

[0058] Figure 4 This is an exemplary structural diagram of a speaker according to some embodiments of this specification.

[0059] In some embodiments, such as Figure 4 As shown, the audio alarm clock 100 also includes a motor 160 (see...). Figure 5 and Figure 6 The button assembly 140 and the motor 160 are connected to the knob 120 via a transmission, and the motor 160 is electrically connected to the button assembly 140.

[0060] In some embodiments, the motor 160 is disposed inside the speaker housing, and the button assembly 140 is disposed on the speaker housing. The motor 160 can drive the knob 120 to rotate. In some embodiments, the knob 120 is connected to a transmission gear 161 (see...). Figure 5 and Figure 6 The motor 160 drives the knob 120 to rotate via the transmission gear 161. Therefore, when the motor 160 rotates, the rotation of the control knob 120 can be controlled by the transmission gear 161.

[0061] The button component 140 can be operated by the user to perform corresponding functions. For example, the user can use the button component 140 to set the alarm time and alarm sound.

[0062] As an example only, when a user wants to set the timer for the audio alarm clock 100, they can control the motor 160 via the button assembly 140 to drive the knob 120 to rotate. In some embodiments, the button assembly 140 can accurately control the rotation of the knob 120, thereby controlling the timer set by the audio alarm clock 100. For example, the button assembly 140 may include a button to control the minute hand and a button to control the hour hand; pressing the button to control the minute hand adjusts the time by one minute, and pressing the button to control the hour hand adjusts the time by one hour.

[0063] The motor rotation knob is controlled by a button assembly, which not only accurately sets the time of the audio alarm clock but also enhances ease of use, saves effort, and improves the user experience.

[0064] Figure 5 This is an exemplary structural diagram of an audio alarm clock in manual mode, as shown in some embodiments of this specification. Figure 6 This is an exemplary structural diagram of an audio alarm clock in electric mode, as shown in some embodiments of this specification.

[0065] In some embodiments, such as Figure 5 and Figure 6 As shown, the audio alarm clock 100 may also include a switching device, which includes a switching lever 171 and a switching groove 172, the switching groove 172 being disposed on the knob 120.

[0066] The switching device can be used to switch the operating mode of the audible alarm clock 100, namely, to switch between manual mode and electric mode. In manual mode, the user can manually rotate the knob 120. In electric mode, the user can control the rotation of the knob 120 through the button assembly 140.

[0067] The switching lever 171 is the part of the switching device that can be directly operated by the user. In some embodiments, the switching lever 171 can be an L-shaped bent part.

[0068] In some embodiments, the switching lever 171 may include a rotatable connecting part 173, a switching part, and an operable operating part. The rotatable connecting part 173 is rotatably connected to the housing 110 or the housing of the speaker, and the switching part engages with the switching groove 172.

[0069] The operating unit is used by the user to operate it. In some embodiments, the operating unit is located outside the housing of the speaker to allow the user to toggle the operating unit to switch between manual and electric modes.

[0070] The switching part is used to cooperate with the switching groove 172 to adjust the position of the audio alarm clock 100 relative to the audio housing. In some embodiments, the switching groove 172 is a groove-shaped structure recessed towards the inside of the knob 120, capable of accommodating the switching part. In some embodiments, the switching part may always be located within the switching groove 172.

[0071] The rotary connector 173 is used to connect the operating part and the switching part, and the rotary connector 173 is located at the bending part of the L-shaped bent part. The rotary connector 173 is rotatably connected to the housing 110 or the housing of the speaker, for example, by means of a pin.

[0072] In some embodiments, the audio alarm clock 100 may further include a limit stop. The limit stop may be set at the extreme position of the switching lever 171 to prevent the switching lever 171 from being over-rotated.

[0073] For example, when switching to manual mode is required, the user can slide the operating part of the switch lever 171 downwards, moving it from a position near the knob 120 to a position away from the knob 120. Since the switch lever 171 is fixed to the housing 110 or the speaker, the knob 120, under the force of the switch lever 171, passively moves away from the motor 160, causing the knob 120 (and the entire dial) to protrude from the plane of the speaker housing, disengaging the knob 120 from the transmission gear 161 of the motor 160. At this time, the alarm clock is switched to manual mode, as shown below. Figure 5 As shown, the user can manually rotate knob 120.

[0074] For example, when switching to electric mode, the user can press knob 120 (and the entire dial) until knob 120 is flush with the speaker housing to activate electric mode. Figure 6 As shown, in electric mode, the operating part is located near the knob 120. The knob 120 meshes with the motor 160 through the transmission gear 161, so that the motor 160 can drive the knob 120 to rotate.

[0075] In the embodiments described in this specification, when switching to manual mode, simply move the operating part of the switching lever; when switching to electric mode, simply press the entire dial and the knob. Therefore, the switching device can achieve switching between manual and electric modes, making operation simple.

[0076] In the embodiments of this specification, by setting two modes, users can either manually experience the specific feel of rotating the knob, or directly set it through the electric mode, increasing the fun and visual appeal.

[0077] In some embodiments, such as Figure 6 As shown, the audio alarm clock 100 may also include a position sensor 180, which is located on the knob 120.

[0078] The position sensor 180 can be used to determine the number of rotations of the knob 120 and the current position of the knob, thereby determining the clock time corresponding to the rotation of the knob 120 or the set timing time of the rotation of the knob 120.

[0079] In some embodiments, such as Figure 4 As shown, the speaker housing can also be equipped with a display component, such as a display screen 150. The display component can be used to display the alarm clock's set time. The user can determine whether the alarm clock's time has been accurately set based on the information displayed on the display component.

[0080] In some embodiments, the motor 160, position sensor 180, and display component may be electrically connected to the audio system's controller. The controller may collect and process data related to the audio system's alarm clock and audio functions to control these functions. For example, the controller may determine the timing of the audio alarm clock 100 based on data collected by the position sensor 180 and send it to the display component.

[0081] In some embodiments, a user can confirm the timing of the audio alarm clock 100 via a terminal. The controller of the audio device (e.g., a Bluetooth speaker) can be wirelessly connected to the terminal and send the timing of the audio alarm clock 100 to the terminal for user confirmation. The terminal is one or more terminal devices or software used by the user. The terminal can be one or any combination of mobile devices, tablet computers, laptop computers, desktop computers, and other devices with input and / or output functions.

[0082] In the embodiments described in this specification, the position sensor can accurately determine the clock time or timing time corresponding to the rotation of the knob, thus avoiding inaccuracies when setting the time.
