Detailed implementation manners

[0048] To make the purpose, technical solutions and advantages of the present application clearer and more definite, the following further elaborates on the present application with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present application and are not used to limit the present application.

[0049] Embodiment 1:

[0050] As Figure 1 、 Figure 2As shown in the figure, this embodiment provides a colorful speaker, which mainly includes: a speaker body 100, a light-transmitting housing 200, a heating device 300, and a lighting device 400. The speaker body 100 can adopt various structures, such as cylindrical, square box-shaped, etc., and is mainly used for playing sound. The light-transmitting housing 200 is connected to the speaker body 100. The light-transmitting housing 200 can be a glass container or a transparent plastic container. The transparent housing can be cylindrical or similar to a cylindrical structure. For the convenience of structural description, in this embodiment, the light-transmitting housing 200 is vertically arranged in the up-down direction as an example. The light-transmitting housing 200 has a receiving cavity 201, which is a cavity inside the light-transmitting housing 200. A liquid and a wax body are arranged in the receiving cavity. The liquid can be water, and the water can fill the entire receiving cavity or cover a part of the receiving cavity. The wax body can be a wax ball or a model wax piece (such as a fish-shaped wax piece, a shrimp-shaped wax piece, etc.). The heating device 300 is arranged outside the receiving cavity and is used to heat the light-transmitting housing 200. In a specific structure, the heating device 300 can be arranged below the transparent housing to heat the bottom of the receiving cavity. The wax piece located in the receiving cavity rises due to the heating of the heating device 300 and descends due to the cooling of the liquid when the wax piece rises to the liquid level of the liquid. The lighting device 400 is arranged outside the receiving cavity and is used to emit light towards the inside of the light-transmitting housing 200. In a specific structure, the lighting device 400 is located below the heating device 300 and emits light towards the inside of the light-transmitting housing 200 through the lighting element 440 thereon. The light emitted by the lighting element 440 can be of various colors, a single color, or change to emit different colors, thereby realizing the colorful lighting effect of the entire light-transmitting housing 200.

[0051] The present embodiment provides a colorful speaker. By providing a light-transmitting housing 200 on the speaker body, a liquid and a wax are mixed inside the light-transmitting housing 200. A heating device 300 is provided below the light-transmitting housing 200. Controlling the heating device 300 can heat the light-transmitting housing 200, and the heat is transferred from the bottom to the wax, causing the wax to rise to the top of the transparent housing after being heated (in the case of being filled with water, if only partially filled with water, then it rises to the liquid level). Since there is a temperature difference between the water temperature at the upper part and the bottom of the transparent housing (the water temperature is higher closer to the bottom, while the upper part may still be relatively cold water), the wax piece that rises to the upper part of the transparent housing cools down and then falls downward, thus achieving the floating effect of the wax piece up and down. Due to the lighting effect emitted by the lighting device 400 at the bottom of the light-transmitting housing 200, shining on the liquid and the wax piece inside the light-transmitting housing 200, a unique visual effect is formed. Combining the colorful lights, the floating of the wax piece in the liquid, and the played music can form a colorful audio-visual state, such as gentle and slow like a young girl, enthusiastic and unrestrained like a volcanic eruption, or soft and light rising and falling. Various novel audio-visual states allow consumers to enjoy a refreshing audio-visual effect, which can make consumers calm, relaxed, forget fatigue and troubles, and relieve the pressure of life and work, etc. It not only increases the functions of the speaker and enhances the audio-visual experience of users, but also the novel display effect enhances the attraction to consumers, adds novel selling points, increases the consumption desire of consumers, makes this product more marketable, and improves the market competitiveness of the product, making it more in line with the needs of market consumption.

[0052] As Figure 1 , Figure 2 , Figure 3 shown, the light-transmitting housing 200 in the present embodiment specifically includes: a bottom shell 210 and a transparent container 220. The bottom shell 210 can be in a non-transparent manner and is mainly connected to the speaker body 100. The transparent container 220 is connected to the bottom shell 210 and forms an accommodation cavity inside. The transparent container 220 can be made of glass, and the display surface of the transparent container 220 can be in any form, such as one side or multiple sides. Therefore, the combination of the light-transmitting housing 200 and the speaker body can be in any form without distinction of up and down, left, middle, or right. A top decorative cover 230 is provided on the transparent container 220 to make the overall appearance of the speaker more beautiful.

[0053] As Figure 2 , Figure 3As shown, further, the bottom shell 210 in this embodiment is mainly divided into: a storage chamber 211 and a workpiece installation chamber 212. The storage chamber 211 is located on the side facing the accommodating chamber; the workpiece installation chamber 212 is located on the side away from the accommodating chamber. In the specific structure, the storage chamber 211 can be located on the upper side and connected to the accommodating chamber as the bottom of the accommodating chamber. The storage chamber 211 is used to store the wax body, and the wax body can be of various colors; the workpiece installation chamber 212 is located on the lower side and separated from the accommodating chamber. The heating device 300 and the light-emitting device 400 can both be arranged in the workpiece installation chamber 212.

[0054] like Figure 3 As shown, further, the specific structure of the bottom shell 210 includes: a bottom plate 213 and an upper retaining ring 214, a docking step is formed between the outer side of the upper retaining ring 214 and the bottom plate 213, the lower end of the transparent container 220 is sleeved on the upper retaining ring 214 and abuts against the edge of the bottom plate 213, and the docking installation is achieved through the docking step. The transparent container 220 can be bonded and fixed to the upper retaining ring 214 and the edge of the bottom plate 213, and a watertight seal is achieved at the connection.

[0055] like Figure 3 , Figure 4 As shown, the bottom shell 210 further includes a lower retaining ring 215, which is arranged on the bottom shell 210 and extends downward to a predetermined height. The upper part of the bottom shell 210 forms a storage cavity 211 and the lower part forms a workpiece installation cavity 212 through the bottom plate 213. Therefore, the lower retaining ring 215 is arranged around the bottom plate 213 to form the workpiece installation cavity 212. The workpiece installation cavity 212 is used to install various functional devices.

[0056] like Figure 3 , Figure 4 As shown, in the specific structure, the upper surface of the bottom plate 213 is recessed downward to form a lower boss 216 in the workpiece mounting cavity 212 and an inner groove 217 in the storage cavity 211. The depth of the storage cavity 211 can be increased by the inner groove 217 that is recessed downward, so that the wax piece is accommodated in the inner groove 217. The boss that protrudes downward can not only serve as abutment surface to install functional components, but also can serve as a heating surface to receive heat from the heating device 300, and effectively conduct the heat to the wax piece in the inner groove 217.

[0057] like Figure 3 , Figure 4As shown, in addition, a clearance space 218 is formed between the side wall of the lower convex platform 216 and the inner wall of the lower retaining ring 215, and the light-emitting element 440 (LED lamp bead) on the light-emitting device 400 is located at the clearance space 218. In a specific structure, as long as the light-emitting device 400 emits light through the light-emitting element 440 (LED lamp bead), one or more LED lamp beads are provided, and preferably a plurality of LED lamp beads are provided. The plurality of LED lamp beads are arranged in a circle. After the light-emitting device 400 is installed in the workpiece installation cavity 212, due to the obstruction of the heating device 300 above, only by avoiding the LED lamp beads arranged in a circle from the heating device 300 can a better light display effect be achieved. Since there is no obstruction in the bottom plate 213 area above the clearance space 218, the LED lamp beads are arranged in the clearance space 218, so that the light can be effectively emitted into the transparent container 220, and the colored lights at the lower end of the light-transmitting housing 200 can use the change of music to drive the lights, making the lights more vivid.

[0058] As Figure 3 shown, due to the setting of the clearance space 218, the light-emitting element 440 (LED lamp bead) is spaced from the surface of the bottom plate 213 above, so that after the bottom plate 213 is heated, it will not come into contact with the LED lamp bead, and thus the heat will not be conducted to the LED lamp bead, avoiding damage to the light-emitting element 440 due to overheating and improving the service life.

[0059] As Figure 3 shown, in the first structure inside the bottom case 210, generally, the heating device 300 can be arranged below the bottom plate 213, and the light-emitting device 400 can be arranged below the heating device 300. The heating device 300 can be abutted against the lower surface of the bottom plate 213 to realize the functions of heating and colorful lights.

[0060] As Figure 4 shown, in the second structure inside the bottom case 210, a heat-conducting member 310 is connected between the heating device 300 and the light-transmitting housing 200. To improve the heating efficiency, by setting the heat-conducting member 310, the heat-conducting member 310 can be a metal sheet with relatively good heat-conducting performance, so that the heat generated by the heating device 300 can be quickly guided to the bottom plate 213 to realize the heating of the wax piece in the storage cavity 211. And as little heat as possible generated by the heating device 300 is conducted downward, so as to improve the heat-conducting efficiency and reduce the influence of temperature rise on the electronic components on the light-emitting device 400.

[0061] As Figure 4As shown, in the third structure inside the bottom case 210, a heat insulation member 410 is provided between the heating device 300 and the lighting device 400. The heat insulation member 410 can be an insulating sheet with relatively poor thermal conductivity. By separating the heating device 300 and the lighting device 400 through the heat insulation member 410, the heat generated by the heating device 300 is conducted to the lighting device 400 as little as possible, effectively protecting the lighting device 400 and preventing damage to the components on the lighting device 400.

[0062] As Figure 4 shown, in a specific structure of the heat insulation member 410, it only includes a partition layer 420. The partition layer 420 can be set as a flat structure. The partition layer 420 is used to be arranged between the heating device 300 and the lighting device 400 to effectively block the heat and prevent the heat of the heating device 300 from directly conducting downward to the lighting device 400 (circuit board).

[0063] As Figure 5 shown, in the second specific structure of the heat insulation member 410, it includes: a partition layer 420 and a surrounding layer 430. The partition layer 420 is used to be arranged between the heating device 300 and the lighting device 400, and the surrounding layer 430 is used to surround the outside of the heating device 300. The partition layer 420 effectively blocks the heat to prevent the heat of the heating device 300 from directly conducting downward to the lighting device 400 (circuit board), and the surrounding layer 430 surrounds the heating device 300 in the middle to prevent a large amount of heated air from the heating device 300 from overflowing from the side of the surrounding layer 430 and affecting the heating device 300 below.

[0064] As Figure 5 shown, in addition, on the basis of the above two structures, the structure of the partition layer 420 is further optimized. Specifically, multiple circles of arched protrusions 421 are provided on the surface of the partition layer 420, and the multiple circles of arched protrusions 421 are concentrically arranged. The heating device 300 is lifted by the tops of the multiple circles of arched protrusions 421. After the heating device 300 is lifted in this way, a line contact is formed between the lighting device 400 and the heating device 300 through the partition layer 420, reducing the contact area and further reducing the heat transfer between the heating device 300 and the lighting device 400. Moreover, ventilation holes 422 are formed below the arched protrusions 421. The ventilation holes 422 can not only provide an installation space for the electronic components (such as diodes, etc.) on the lighting device 400 (circuit board), but also allow air to circulate, facilitating the heat dissipation of the circuit of the lighting device 400 (circuit board). The function of the circuit for realizing the lighting of the light-emitting element 440 is made more stable.

[0065] As Figure 5As shown, in addition, based on the structure of the second heat insulation member 410 described above, in order to improve the light-emitting effect, the outer sidewall of the enclosure layer 430 can be structurally optimized. Specifically: an optical microstructure 431 is provided on the outer sidewall of the enclosure layer 430. The optical microstructure 431 can be various prism microstructures. Through the optical microstructure 431, the light emitted by the light-emitting member 440 is reflected and diffused, so that the light emitted from the edge of the bottom plate 213 is more evenly distributed within the light-transmitting housing 200. This avoids the concentration of light in the area of the avoidance space at the edge of the bottom plate 213, which causes the problem of local over-darkness of the light-transmitting housing 200. For example, some of the light emitted from the edge of the bottom plate 213 can be inclined towards the central axis direction of the light-transmitting housing 200, providing illumination for the central position of the light-transmitting housing 200 and avoiding the problem of an over-dark area formed at the central position of the light-transmitting housing 200 due to the absence of a light-emitting member 440 there.

[0066] As Figure 5 shown, correspondingly, an optical microstructure 431 can also be provided on the inner sidewall of the lower retaining ring 215. Under the cooperative action of the optical microstructure 431 on the outer sidewall of the enclosure layer 430 and the optical microstructure 431 on the inner sidewall of the lower retaining ring 215, the optical microstructure 431 reflects and diffuses the light emitted by the light-emitting member 440, so that the light emitted from the edge of the bottom plate 213 is more evenly distributed within the light-transmitting housing 200, improving the light-emitting uniformity and further enhancing the user's visual experience.

[0067] As Figure 2 、 Figure 3 shown, further, a water pump 500 is also provided in the workpiece mounting cavity 212 in this embodiment. Both the water outlet end and the water inlet end of the water pump 500 pass through the bottom case 210 and communicate with the accommodating cavity. In the specific structure, an insertion pipe 510 is fixedly provided on the water pump 500. The water outlet end and the water inlet end of the water pump 500 can be in the form of pipes and placed within the insertion pipe 510. The insertion pipe 510 on the water pump 500 extends upward and penetrates the bottom case 210. Specifically, a bottom hole can be opened at the center of the bottom case 210, and the insertion pipe 510 penetrates the bottom hole. A sealing ring is provided on the inner wall of the bottom hole, and the sealing ring is sleeved on the outer wall of the insertion pipe 510 to prevent the bottom case 210 from leaking water.

[0068] Through the water pump 500, the water in the accommodating cavity can be circulated. Using the principle of the water pump 500, the fluidity of the water within the light-transmitting housing 200 is increased, allowing the floating wax pieces to form colorful states. The pumping speed of the water pump 500 can be controlled, so that states such as gentle, enthusiastic, light rising and falling, etc. can be formed, increasing the ornamental value of the floating wax pieces.

[0069] In the specific structure of the audio body 100, various forms can be adopted. For example:

[0070] As Figure 1 、Figure 2 As shown in the figure, the first structure of the audio body 100 specifically includes: a chassis 110 and a vertical housing 120. The chassis 110 can be a frustum of a cone or an arc table, etc. The vertical housing 120 is arranged on the chassis 110. A speaker 121 is arranged on the vertical housing 120, and a main control board 140 and a power supply battery 150 are arranged inside the vertical housing 120. A light-transmitting housing 200 is arranged at the top of the vertical housing 120.

[0071] As Figure 6 shown in the figure, the second structure of the audio body 100 specifically: an outer housing 130, and a through mounting hole 131 is opened on the outer housing 130; a plurality of speakers 121 can be arranged on the outer housing 130, a main control board 140 and a battery 150 are arranged inside the outer housing 130, and a light-transmitting housing 200 is arranged in the through mounting hole 131.

[0072] In addition to the above structures, the audio body 100 can also adopt other structures. As long as the audio signal playing function is realized, the technical effects of this application can be achieved.

[0073] Embodiment 2:

[0074] As Figure 7 shown in the figure, this embodiment proposes a control circuit for a colorful speaker, which is applied to the colorful speaker as described above. The control circuit of the colorful speaker mainly includes: a speaker 121, a light-emitting component 440, and a main controller 141. The main controller 141 is mainly arranged on the main control board 140 (as Figure 2 shown in the figure). The main controller 141 can adopt Jerry's 7016F8 or Qualcomm Bluetooth chip qcc3034, and the main controller can be an IC that realizes the Bluetooth function. The speaker 121 is arranged on the audio body 100, and one or more speakers 121 can be arranged according to needs, so as to be used for emitting sound and playing audio signals. The light-emitting component 440 is arranged on the light-emitting device 400, and mainly adopts LED lamp beads, and the LED lamp beads are welded on the circuit board of the light-emitting device 400. The main controller 141 is electrically connected to the speaker 121, the light-emitting component 440 and the heating device 300 respectively. The main controller 141 is used for receiving audio signals and playing sounds through the speaker 121, and controlling the light-emitting component 440 for light display, and controlling the heating device 300 for heating, so that the wax in the accommodating cavity rises through the heating of the heating device 300 and descends through the cooling of the liquid. In a specific structure, the main controller 141 is responsible for receiving and processing various control instructions and processing signals, and can integrate various circuits and chips, such as functions for controlling the switch, volume adjustment, and playback mode switching of the speaker.

[0075] The existing electronic circuit of the colorful audio can control the change of light and keep the light on constantly. Based on the existing electronic circuit of the colorful audio, in this embodiment, by controlling the heating device 300, a more novel display effect is achieved, which enhances the attraction to consumers. The speaker and the wax lamp are integrated to form a new audio product, enabling the floating of the wax body to be combined with the light of the audio, making the sound playback of the audio more vivid. Through this control circuit, not only can the individual control of the light, sound playback, and wax part floating be realized, but also the wax part can float and the light can move with the music. The light and water flow can be changed according to the change of the music, and the change of the water flow makes the wax body produce rich and diverse forms, enabling the audio playback, light, and wax body floating to form a coordinated state, further enhancing the attraction of the product to consumers.

[0076] Further, the main controller 141 is electrically connected to a Bluetooth module 600, and the Bluetooth module 600 is electrically connected to a speaker 121. There are existing chips that can directly provide Bluetooth functions and processing functions. Therefore, the Bluetooth module 600 and the control module can be regarded as a whole in the circuit. The overall chip of the Bluetooth module 600 and the main controller 141 is the core of the speaker, which is used to convert electrical signals into sound signals. The Bluetooth module 600 is responsible for pairing and communicating with other Bluetooth devices to achieve the wireless transmission of external audio and ensure the stable transmission of audio signals. The main controller 141 works in coordination with the Bluetooth module 600 to control the operation and communication of other related devices and enable other devices to work properly.

[0077] Further, the main controller 141 is electrically connected to a water pump 500. The water pump 500 is used to control the floating speed of the wax part in the light-transmitting housing 200 under the action of water flow. In the specific process, the main controller 141 can control the pumping speed of the water pump 500 according to the switch signal of the key switch 620, or the main controller 141 can control the pumping speed of the water pump 500 according to the played audio information. For example, the water pump 500 controls the floating and sinking speed of the wax part by pumping water speed. It is used to send a speed control instruction through the key switch 620. After receiving the speed control instruction, the main controller 141 retrieves the corresponding preset speed value and controls the water pump 500 according to this preset speed value. For example, the audio signal played by the speaker is converted by the sound effect conversion module 630, and different speed control signals are output according to the music content of the audio signal. The main controller 141 makes the pumping speed of the water pump 500 different according to different speed control signals, so that the flow rate of the water pump 500 follows the music effect to beat, making the wax ball in the water more vivid.

[0078] Further, a temperature detector 610 is electrically connected to the main controller 141. The temperature detector 610 is used to detect the internal water temperature on the side of the light-transmitting housing 200 facing the heating device 300, and the temperature detector 610 is used in cooperation with the heating device 300. The main controller 141 controls the rising speed of the wax part by controlling the heating speed of the heating device 300 (controlling the time for the wax part to rise from the bottom to the start of rising, as well as the floating time for rising and falling); after detecting the internal water temperature by the temperature detector 610, the main controller 141 controls the heating temperature of the heating device 300 according to the internal water temperature to reach the predetermined temperature for the wax part to rise. In the specific process, the heating device 300 is an important device for accelerating the floating of the wax body. By controlling the speed of heating, the rising and falling speed of the wax body can be controlled. The heating device 300 and the temperature detector 610 are key components for balancing the floating effect in the light-transmitting housing 200. After reaching the temperature for the wax ball to rise, the internal water temperature in the light-transmitting housing 200 will be stabilized by the temperature detector 610, making the internal water temperature beneficial to the shape of the wax ball.

[0079] Further, the light-emitting part 440 (LED lamp) on the light-emitting device 400 is used for light effect display. The lighting effect can be set to change in a fixed manner by the key switch 620 on the speaker. For example, after the key switch 620 is activated, the light-emitting part 440 emits light according to a predetermined rule. It can also be converted through the sound effect conversion module 630 according to the music content of the audio signal played on the speaker. Different lighting control signals are output according to the music content of the audio signal. The main controller 141 makes the lighting effect of the light-emitting part 440 different according to different lighting control signals, so that the lighting effect follows the music effect and beats, making it more vivid and enhancing the fun.

[0080] Further, the battery 150 provides power for each device in the control circuit to ensure that the speaker can work continuously. The control circuit further includes a power supply interface 640, a charging module 641, and a power conversion module 642. The power supply interface 640 is the external power supply interface 640 of the entire speaker; the charging module 641 provides charging and charging protection for the battery 150; the power conversion module 642 is the power supply end of the entire system, providing necessary power support for other modules to enable other modules to work properly, such as the power amplifier power supply module, the Bluetooth power supply module, the main controller 141 power supply module, the heating power supply module, the lamp power supply module, and the water pump 500 power supply module.
