Description

Technical Field

[0001] The present invention relates to the technical field of sound boxes, and more particularly to a luminous sound box. Background Art

[0002] With the improvement of people's living standards, speakers have become a very important appliance in people's lives as an important tool for creating a home music environment. The main function of existing speakers is to convert electricity and sound so that sound can be reproduced. Multiple light-emitting devices are set on the speakers. The light-emitting devices have light bulbs for emitting light. The light bulbs can be set in a variety of colors to create a bright and colorful effect.

[0003] Luminous speakers are very popular in places for entertainment such as square dancing, and the speakers and the lights on their surfaces can create an atmosphere. Although existing luminous speakers can emit single-color or multi-color patterns with specific shapes, the light-transmitting area on the speakers used to form the pattern is fixed and fails to "dance" with the music. The light-transmitting area lacks a three-dimensional sense, resulting in a relatively monotonous luminous effect and failing to liven up the atmosphere. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a luminous speaker to solve the problem that the light-transmitting area used to form a pattern on the existing speaker fails to "dance" with the music, resulting in a relatively monotonous luminous effect and failing to liven up the atmosphere.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A luminous speaker comprises a box body with a receiving cavity, an active sound unit, a circuit board, a battery pack, and a light unit; the active sound unit, the circuit board, the battery pack, and the light unit are all arranged in the receiving cavity of the box body; the active sound unit, the battery pack, and the light unit are all electrically connected to the circuit board; a light-transmitting diaphragm is provided on the box body, the inner wall of the diaphragm is connected to the receiving cavity of the box body, a counterweight is provided on the outer wall of the diaphragm, the counterweight is provided with a mist region and a light-transmitting region, and the light-transmitting region forms a pattern identifier.

[0007] Optionally, the diaphragm includes a folding ring portion made of an elastic material and a bonding portion arranged on the inner side of the folding ring portion, and the bonding portion is made of a light-transmitting material.

[0008] Optionally, a masking coating is provided on the side of the foggy area of ​​the counterweight close to the diaphragm to prevent light from penetrating, and a plating layer is provided on the side of the light-transmitting area of ​​the counterweight close to the diaphragm to allow light to penetrate.

[0009] Optionally, the thickness of the electroplating layer is 600-1000nm.

[0010] Optionally, a first magnetic component is embedded on the outer wall of the diaphragm, a second magnetic component is embedded on the inner wall of the counterweight close to the diaphragm, and the first magnetic component is magnetically connected to the second magnetic component.

[0011] Optionally, the first magnetic component and the second magnetic component are both magnets; or the first magnetic component is a magnet, and the second magnetic component is a hardware component; or the first magnetic component is a hardware component, and the second magnetic component is a magnet.

[0012] Optionally, a weight identifier for displaying the weight of the counterweight is provided on the outer wall of the counterweight.

[0013] Optionally, a music identifier for displaying the type of music that the counterweight is adapted for is provided on the outer wall of the counterweight.

[0014] Optionally, the box body includes an inner shell and a metal shell made of light-transmitting material; the metal shell is sleeved with the inner shell; a diaphragm hole connected to the accommodating cavity is opened on the inner shell, and the edge of the diaphragm is sealed on the diaphragm hole; a counterweight hole is opened at a position corresponding to the diaphragm hole on the metal shell, and a light-transmitting gap exists between the edge of the counterweight and the inner wall of the counterweight hole; the light emitted by the light-emitting unit is transmitted to the outside of the box through the light-transmitting gap in the form of side-lighting.

[0016] In summary, the present invention has the following beneficial effects: (1) By setting a light-transmitting area on the counterweight to form a pattern identifier, the pattern identifier can transmit a pattern of a specific shape under the action of the light-emitting unit, and the light-transmitting area used to form this pattern can "jump" with the music under the action of the active sound-emitting unit, presenting a better three-dimensional sense and a better livening up the atmosphere. (2) The counterweight is installed on the diaphragm by magnetic adsorption, and the user can quickly replace the corresponding counterweight according to the type of music played, so that the passive radiator formed by the box, the diaphragm and the counterweight follows the vibration of the active sound-emitting unit to make a suitable instantaneous response, thereby improving the bass effect of the speaker. (3) The counterweight is installed on the diaphragm by magnetic adsorption, so that the user does not need to visually align the counterweight when replacing it, and the counterweight can achieve an automatic positioning effect. (4) The light emitted by the light-emitting unit forms an ambient light at the edge of the counterweight through the reflection and / or transmission of the light-transmitting inner tank and / or the folding ring, and is transmitted to the outside of the box through the light-transmitting gap in the form of lateral light emission, avoiding the ambient light from directly hitting the user's eyes and improving the user experience.

[0029] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] The present invention provides a luminous sound box, such as Figure 1-8 As shown, it includes a box body 1 with a accommodating cavity, an active sound unit 2, a circuit board 3, a battery pack 4, and a light-emitting unit 7; the active sound unit 2, the circuit board 3, the battery pack 4, and the light-emitting unit 7 are all arranged in the accommodating cavity of the box body 1; the active sound unit 2, the battery pack 4, and the light-emitting unit 7 are all electrically connected to the circuit board 3; a light-transmitting diaphragm 5 is provided on the box body 1, the inner wall of the diaphragm 5 is connected to the accommodating cavity of the box body 1, and a counterweight 6 is provided on the outer wall of the diaphragm 5, the counterweight 6 is provided with a foggy area and a light-transmitting area, and the light-transmitting area forms a pattern identifier 64.

[0031] In this embodiment, the box body 1 is made of plastic or plywood, and a through hole is opened at the position corresponding to the active sound unit 2 and the diaphragm 5 on the side wall for installing the corresponding active sound unit 2 or diaphragm 5. The specific installation method is the existing technology and will not be repeated here. The active sound unit 2 includes a woofer and a tweeter, which are respectively installed at the lower end and the upper end of the front of the box body 1. The circuit board 3 is an amplifier board with integrated charging function in the prior art, which can be connected to an external power supply to charge the battery pack 4 and is electrically connected to the active sound unit 2 and the battery pack 4 through a wire. The battery pack 4 is composed of two 18650 lithium batteries, which are installed inside the box body 1 by existing fixing methods such as hot melt adhesive, and are close to the rear baffle of the box body 1. The edge of the diaphragm 5 is sealed and bonded to the left and right side walls of the box body 1 by adhesive, and it is partially light-transmissive, which can transmit the light emitted by the light-emitting unit 7 to the counterweight 6. The counterweight 6 is made of PC, PMMA or other light-transmitting materials by injection molding. The surface is made misty by etching the texture at the position of the non-pattern identifier 64 on the mold, which is a misty frosted effect that is light-transmitting but not highly transparent. The position of the pattern identifier 64 is light-transmitting, and light passes through the pattern identifier 64 to display the brand name or LOGO of the speaker or other specific shapes of patterns in a luminous manner.

[0032] The present invention forms a pattern identifier 64 by arranging a light-transmitting area on the counterweight 6, so that the pattern identifier 64 can transmit a pattern of a specific shape under the action of the light-emitting unit 7, and the light-transmitting area used to form this pattern can "dance" with the music under the action of the active sound-emitting unit 2, so that the user can see a pattern that dances in coordination with the music at night, presenting a better three-dimensional effect and better livening up the atmosphere.

[0033] Furthermore, the diaphragm 5 includes a folded ring portion 52 made of an elastic material and a bonding portion 53 arranged inside the folded ring portion 52 , and the bonding portion 53 is made of a light-transmitting material.

[0034] like Figure 7 As shown, the diaphragm 5 is composed of a folding ring portion 52 and a bonding portion 53. The two are bonded and fixed by an adhesive. The folding ring portion 52 is made of a light-transmitting or opaque silicone / rubber material, and the bonding portion 53 is made of a hard light-transmitting material such as PC, which is generally a flat plate-shaped body, providing a bonding position for the counterweight 6.

[0035] Furthermore, a masking coating is provided on the side of the foggy area of ​​the counterweight 6 close to the diaphragm 5 to prevent light from penetrating, and a plating layer is provided on the side of the light-transmitting area of ​​the counterweight 6 close to the diaphragm 5 to allow light to penetrate.

[0036] Specifically, the covering coating is a dark coating such as black, which is applied to the foggy area on the back of the counterweight 6 by spraying or silk-screening, so that the pattern identifier 64 can emit a brighter pattern. The electroplating layer is deposited in the light-transmitting area by PVD process, forming a unique one-way mirror effect, that is, when observing from the outside of the counterweight 6 to the inside, the pattern identifier 64 is a mirror effect, and the electronic components inside the box 1 cannot be seen, and the light emitted by the light-emitting unit 7 cannot be completely covered, thereby improving the appearance of the speaker. The inventor has found through multiple verifications that the thickness of the electroplating layer between 600-1000nm can allow most of the light to pass through, and also has sufficient covering power to prevent users from seeing the electronic components inside the box 1 through the pattern identifier 64.

[0037] Furthermore, a first magnetic member 51 is embedded on the outer wall of the diaphragm 5 , and a second magnetic member 61 is embedded on the inner wall of the counterweight 6 close to the diaphragm 5 . The first magnetic member 51 is magnetically connected to the second magnetic member 61 .

[0038] like Figure 4-7 As shown, a counterweight 6 is magnetically adsorbed on the outer wall of the diaphragm 5 (the counterweight 6 also serves as a decorative piece), and the counterweight 6 can be separated from the diaphragm 5, but it also has sufficient adsorption force to ensure that it will not fall off during the listening process. There are multiple counterweights 6, and the main difference is that their weights are different, such as 10 grams, 20 grams, 30 grams, 50 grams, etc., which are used to adapt to different types of music, and users can choose according to their subjective feelings. The general rule is: when listening to rock and heavy metal music, use a heavier counterweight 6; when listening to electronic, pop, and pure sound music, use a lighter counterweight 6.

[0039] The outer wall of the diaphragm 5 has a groove, in which the first magnetic component 51 is tightly embedded; the inner wall of the counterweight 6 close to the diaphragm 5 also has a groove, in which the second magnetic component 61 is also tightly embedded; when the first magnetic component 51 and the second magnetic component 61 are connected and close to each other, they can be adsorbed together.

[0040] The present invention installs the counterweight 6 on the diaphragm 5 by magnetic adsorption, and the user can quickly replace the corresponding counterweight 6 according to the different types of music played, so that the passive radiator formed by the box 1, the diaphragm 5 and the counterweight 6 follows the vibration of the active sound unit 2 to make a suitable instantaneous response, thereby improving the bass effect of the speaker. The defect that the counterweight in the passive radiator disclosed in the CN204906671 U and CN216852218U patents cannot be replaced and cannot be well adapted to different types of music is overcome.

[0041] In addition, a strong double-sided adhesive layer can be adhered to the bottom surface of the first magnetic member 51 in contact with the diaphragm 5 to enhance the firmness between the first magnetic member 51 and the diaphragm 5. Similarly, a strong double-sided adhesive layer can be adhered to the bottom surface of the second magnetic member 61 in contact with the counterweight 6 to enhance the firmness between the second magnetic member 61 and the counterweight 6. Both the first magnetic member 51 and the second magnetic member 61 are in the shape of a ring, and can realize the automatic alignment function.

[0042] The counterweight 6 in the present invention is installed on the diaphragm 5 by magnetic adsorption. Compared with other detachable methods (such as interference fit), the user does not need to visually align the counterweight 6 when replacing it. The counterweight 6 can achieve automatic positioning, which is more convenient and quick.

[0043] Further, the first magnetic component 51 and the second magnetic component 61 are both magnets; or the first magnetic component 51 is a magnet, and the second magnetic component 61 is a hardware; or the first magnetic component 51 is a hardware, and the second magnetic component 61 is a magnet.

[0044] Specifically, at least one of the first magnetic attraction component 51 and the second magnetic attraction component 61 is a magnet, and the other can be a magnet or a hardware component that can be attracted by a magnet. The hardware component is mainly made of metals such as iron, cobalt, nickel, or their alloys.

[0045] Furthermore, a weight identifier 62 for displaying the weight of the counterweight 6 is provided on the outer wall of the counterweight 6 .

[0046] like Figure 7 As shown, the weight identifier 62 shows the weight of the counterweight 6, such as 10 grams, 20 grams, 30 grams, 50 grams, etc., which can be set according to actual needs. This setting is convenient for users to quickly find the counterweight 6 of the target weight.

[0047] Furthermore, a music identifier 63 for displaying the type of music that the counterweight 6 is adapted for is provided on the outer wall of the counterweight 6 .

[0048] like Figure 7 As shown, the music identifier 63 shows what types of music the counterweight 6 is generally suitable for. For example, if it is marked as "rock", it means that the counterweight 6 is suitable for use when listening to rock music. The music identifier 63 can also be used in combination with the weight identifier 62. For example, "30 grams, rock" means that the counterweight 6 is suitable for use when listening to light rock music, and "40 grams, rock" means that the counterweight 6 is suitable for use when listening to heavy rock music. This setting makes it easy for users to quickly find the target type of counterweight 6 that matches the music type.

[0049] Furthermore, the box body 1 includes an inner shell 11 and a metal shell 12 made of light-transmitting material; the metal shell 12 is sleeved with the inner shell 11; the inner shell 11 is provided with a diaphragm 5 hole 111 connected to the accommodating cavity, and the edge of the diaphragm 5 is sealed on the diaphragm 5 hole 111; a counterweight hole 121 is provided at a position corresponding to the diaphragm 5 hole 111 on the metal shell 12, and a light-transmitting gap exists between the edge of the counterweight 6 and the inner wall of the counterweight hole 121; the light emitted by the light-emitting unit 7 is transmitted to the outside of the box body 1 in a sideways light-emitting manner through the light-transmitting gap.

[0050] like Figure 1-7 As shown, the inner liner 11 is made of light-transmitting materials such as PC by injection molding, and the texture is etched on the mold to make its surface foggy, showing a light-transmitting but not highly transparent foggy frosted effect. The left and right side walls are provided with diaphragm holes 111 for installing the diaphragm 5. The front is provided with a large and a small through hole for installing the woofer and the tweeter respectively. The back is hollowed out to facilitate the installation of components such as the active sound unit 2, the circuit board 3, and the battery pack 4 in the accommodating cavity. The metal shell 12 is made of metals such as aluminum, zinc, and their alloys. The back is hollowed out to facilitate the insertion of the inner liner 11. The scheme of the metal shell 12 and the inner liner 11 to form the box body 1 makes the box body 1 present a unique metallic texture to the outside and a light-guiding effect to the inside. The edge of the diaphragm 5 is sealed and bonded to the diaphragm hole 111 by an adhesive. The contour of the counterweight hole 121 is consistent with the diaphragm hole 111, and there is a light-transmitting gap between it and the edge of the counterweight 6 (see Figure 4 The position shown in D in the figure), the width of the light-transmitting gap is 3-8mm, which can be set according to actual needs, and is preferably 5mm. At least one light-emitting unit 7 is installed inside the inner liner 11 of the box body 1. A plurality of RGB light-emitting wicks are attached to the light-emitting unit 7, which can emit light of various colors according to actual needs to meet the subjective needs of users and improve user experience. The light emitted by the light-emitting unit 7 forms a circle of soft light band at the position of the light-transmitting gap after the light-guiding effect formed by the reflection and / or projection of the inner liner 11 and the reflection effect of the counterweight 6, and will not irradiate the outside of the box body 1 in a direction perpendicular to the outer wall of the box body 1, that is, the light will not be Figure 1 The light is emitted directly out of the box 1 in the Y-axis direction. The light path diagram can be referred to Figure 8 This structural setting avoids the ambient light formed by the soft light band from directly shining into the user's eyes, improves the user experience, and overcomes the problem that the light-emitting unit of the luminous speaker disclosed in the patents with announcement numbers CN216408857U3 and CN215808308U emits light in a direct manner (the light-emitting direction is perpendicular to the box body). When the user faces the speaker, the eyes are easily illuminated by the light in a vertical manner, causing discomfort.

[0051] Furthermore, in order to protect the active sound unit 2 from being squeezed and dented, a dustproof mesh cover (not shown in the drawings) is provided on the front of the box 1, and the dustproof mesh cover is installed on the front of the box 1 by magnetic attraction or snap-fitting.

[0052] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
