Technical Field

[0001] The utility model relates to the technical field of sound boxes, and more particularly to a passive radiator and a sound box. Background Art

[0002] In order to obtain better bass effect, most speakers will install one or more passive radiators on the cabinet; the passive radiator is usually composed of a bracket, a diaphragm, and a counterweight, as shown in the passive radiator and speaker disclosed in patent announcement numbers CN204906671U and CN216852218U.

[0003] The passive radiator structure described in the two aforementioned patents can be summarized as follows: the edge of the diaphragm is bonded to the bracket, and the counterweight is attached to the center of the diaphragm. This structure makes the counterweight non-replaceable, making it difficult to adapt to different types of music (different types of music require different counterweights to ensure the diaphragm's transient response is more appropriate). For example, a small counterweight is not suitable for rock and heavy metal music, while a large counterweight is not suitable for electronic music, pop music, or pure music. Utility Model Content

[0022] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0023] The utility model provides a passive radiator, such as Figure 1-3 As shown, a bracket 1 is provided with a diaphragm 2 sealed thereon, and a counterweight 3 is provided on the outer wall of the diaphragm 2 facing the user, and the counterweight 3 can be separated and removed from the diaphragm 2.

[0024] In this embodiment, the bracket 1 is made of plastic or metal sheet, and the edge of the diaphragm 2 is sealed and bonded to the end of the bracket 1 by adhesive. There is a counterweight 3 on the outer wall of the diaphragm 2. The counterweight 3 can be separated from the diaphragm 2, but it also has sufficient adsorption force to ensure that it will not fall off during listening to music. The counterweight 3 is installed on the diaphragm 2 in an existing detachable manner such as magnetic adsorption, inlay structure, snap-on structure, threaded fit, etc. A passive radiator is equipped with multiple counterweights 3. The main difference between the multiple counterweights 3 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. Users can choose according to their subjective feelings. The general rule is: when listening to rock and heavy metal music, use a counterweight 3 with a heavier weight; when listening to electronic, pop, and pure sound music, use a counterweight 3 with a lighter weight.

[0025] The utility model preferably installs the counterweight 3 on the diaphragm 2 by magnetic adsorption. The user can quickly replace the corresponding counterweight 3 according to the type of music played, so that the passive radiator formed by the cabinet 1, diaphragm 2 and counterweight 3 makes an appropriate instantaneous response following the vibration of the active sound unit 2, thereby improving the bass effect of the speaker.

[0026] Furthermore, a first magnetic member 21 is embedded on the outer wall of the diaphragm 2 , and a second magnetic member 31 is embedded on the inner wall of the counterweight 3 close to the diaphragm 2 . The first magnetic member 21 and the second magnetic member 31 are magnetically connected.

[0027] like Figure 1-3 As shown, the outer wall of the diaphragm 2 has a groove, in which the first magnetic component 21 is tightly embedded; the inner wall of the counterweight 3 close to the diaphragm 2 also has a groove, in which the second magnetic component 31 is also tightly embedded; when the first magnetic component 21 and the second magnetic component 31 are connected and close to each other, they can be adsorbed together.

[0028] In addition, a strong double-sided adhesive layer can be applied to the bottom surface of the first magnetic member 21 where it contacts the diaphragm 2, thereby enhancing the secure connection between the first magnetic member 21 and the diaphragm 2. Similarly, a strong double-sided adhesive layer can be applied to the bottom surface of the second magnetic member 31 where it contacts the counterweight 3, thereby enhancing the secure connection between the second magnetic member 31 and the counterweight 3. Both the first magnetic member 21 and the second magnetic member 31 are circular, enabling automatic alignment.

[0029] The counterweight 3 in the present invention is installed on the diaphragm 2 by a magnetic adsorption scheme. Compared with other detachable methods (such as interference fit, convex and slot fit), the user does not need to visually align the counterweight 3 when replacing it. The counterweight 3 can achieve automatic positioning effect, which is more convenient and quick.

[0030] Furthermore, the first magnetic component 21 and the second magnetic component 31 are both magnets; or the first magnetic component 21 is a magnet, and the second magnetic component 31 is a hardware component; or the first magnetic component 21 is a hardware component, and the second magnetic component 31 is a magnet.

[0031] Specifically, at least one of the first magnetic component 21 and the second magnetic component 31 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.

[0032] Furthermore, a weight identifier 32 for displaying the weight of the counterweight 3 is provided on the outer wall of the counterweight 3 .

[0033] like Figure 2 As shown, the weight identifier 32 shows the weight of the counterweight 3 itself, such as 10 grams, 20 grams, 30 grams, 50 grams, etc., which can be set according to actual needs. This setting makes it easy for users to quickly find the counterweight 3 of the target weight.

[0034] Furthermore, a music identifier 33 for displaying the type of music that the counterweight 3 is adapted for is provided on the outer wall of the counterweight 3 .

[0035] like Figure 2 As shown, music identifier 33 indicates which types of music this counterweight 3 is generally suitable for. For example, if it is labeled "Rock," this means that this counterweight 3 is suitable for listening to rock music. Music identifier 33 can also be used in conjunction with weight identifier 32. For example, "30 grams, Rock" indicates that this counterweight 3 is suitable for listening to light rock music, while "40 grams, Rock" indicates that this counterweight 3 is suitable for listening to heavy rock music. This setting makes it easy for users to quickly find the target type of counterweight 3 that matches the music genre.

[0036] Furthermore, the diaphragm 2 includes a transparent folding ring portion 22 and an adhesive portion 23 arranged on the inner side of the folding ring portion 22 . The counterweight 3 has a foggy area and a high-transmittance area, and the high-transmittance area forms a brand identifier 34 .

[0037] like Figure 2As shown, the diaphragm 2 consists of a folding ring portion 22 and an adhesive portion 23. The folding ring portion 22 is made of a translucent silicone / rubber material, and the adhesive portion 23 is made of a hard material such as carbon fiber. It is generally a flat plate-like body, providing a bonding position for the counterweight 6, and the first magnetic member 21 is embedded in the adhesive portion 23. The counterweight 3 is injection-molded from a translucent material such as PC or PMMA. By etching a texture at the position of the non-brand identifier 34 on the mold, its surface becomes foggy, presenting a translucent but not highly translucent foggy frosted effect. The position of the brand identifier 34 creates a highly translucent effect, displaying the brand name or LOGO of the speaker in a luminous manner. At this time, the counterweight 3 also serves as a decorative part for decorating the speaker. In addition, in order to make the luminous effect of the brand identifier 34 and the translucent gap more transparent and distinct, a light-shielding coating can be provided in the foggy area of ​​the counterweight 3, specifically on the inner wall of the counterweight 3.

[0038] The present invention also provides a speaker, the main feature of which is that the above-mentioned passive radiator is installed on the box body by an existing fixing method. The box body is made of plastic or plywood, and its interior is a hollow structure for installing active sound units (treble and woofers), power amplifier boards, battery packs, light panels, operation panels and other common electronic parts in the speaker field. In some embodiments, the box body and the bracket 1 are integrally injection-molded from translucent or opaque plastic, so that the box body of the speaker is the bracket 1 of the passive radiator, thereby reducing the use of parts and improving the compactness of the speaker structure.
