Description

Technical Field

[0001] This application relates to the field of audio playback device technology, and more particularly to a loudspeaker and an attached resonant sound. Background Technology

[0002] Traditional audio loudspeakers consist of a voice coil, a magnet, and a frame. When an audio current is passed through the voice coil, it generates a magnetic field. This magnetic field interacts with the magnetic field generated by the magnet, causing the voice coil to vibrate relative to the magnet. This vibration, in turn, causes the frame to vibrate, producing sound. The frame of traditional audio loudspeakers is funnel-shaped and is usually located inside the speaker housing. This frame limits the external dimensions of the speaker housing, preventing traditional loudspeakers from becoming smaller and lighter, and thus failing to simultaneously meet people's desire for both beautiful sound effects and portability. Summary of the Invention

[0003] The purpose of this application is to provide a loudspeaker and an attached resonant speaker. The loudspeaker of this application can be attached to an external medium surface through an adsorption surface, so that the vibration of the resonator can be transmitted to the external medium surface, causing it to resonate and produce sound. The attached resonant speaker of this application, using the above-mentioned loudspeaker structure, can be attached to the medium surface and resonate with the medium surface to produce sound. Moreover, it eliminates the need for a frame, greatly reducing the size. Thus, the attached resonant speaker of this application can be developed towards miniaturization and portability, to meet people's pursuit of beautiful sound effects and easy portability.

[0004] To this end, in a first aspect, embodiments of this application provide a loudspeaker comprising: a resonator configured to vibrate in response to an audio current; the loudspeaker having an adsorption surface disposed on one side of the resonator.

[0006] In some possible implementations, the resonator has the magnetic attraction surface.

[0007] In some possible implementations, the loudspeaker further includes a magnetic patch attached to one side of the resonator, the magnetic patch having the magnetic attraction surface.

[0008] In some possible implementations, the magnetic patch includes a soft magnetic patch and a hard magnetic patch.

[0009] In some possible implementations, the resonator includes a resonant diaphragm.

[0010] In some possible implementations, the loudspeaker further includes a voice coil configured to be energized with an audio current to generate vibration; a resonator is attached to one side of the voice coil and resonates with the voice coil; and an adsorption surface is located on the side of the resonator opposite to the voice coil.

[0011] In some possible implementations, the loudspeaker further includes a first magnet and an iron rod; the first magnet is sleeved on the outer periphery of the iron rod, the voice coil is disposed on one side of the first magnet, and the resonator is located on the side of the voice coil opposite to the first magnet; or, the loudspeaker further includes a second magnet and an iron cylinder; the second magnet is disposed inside the iron cylinder, the voice coil is disposed on one side of the second magnet, and the resonator is located on the side of the voice coil opposite to the second magnet.

[0012] In some possible implementations, when the loudspeaker includes the first magnet, the iron rod, the voice coil, and the resonator, the center lines of the iron rod, the first magnet, the voice coil, and the resonator all coincide; when the loudspeaker includes the second magnet and the iron cylinder, the center lines of the iron cylinder, the second magnet, the voice coil, and the resonator all coincide.

[0013] In some possible implementations, the loudspeaker is a magnetostrictive rare-earth horn, an electromagnetically driven horn, or a vibrating horn, and the magnetostrictive rare-earth horn, the electromagnetically driven horn, and the vibrating horn all include the resonator.

[0014] In a second aspect, this application also proposes an attached resonant speaker, which includes a housing and a loudspeaker as described in the first aspect; a through hole is provided on one side of the housing; the loudspeaker includes the resonator, which is configured to vibrate to extend out of or retract into the through hole.

[0015] In some possible implementations, the housing defines a resonant cavity that communicates with the through hole; the loudspeaker includes the first magnet and the iron rod, both of which are located within the resonant cavity; or, the loudspeaker includes the second magnet and the iron cylinder, both of which are located within the resonant cavity.

[0016] In some possible implementations, the housing contains a first damping element and a second damping element; when the loudspeaker includes the iron rod, the first damping element is disposed between the iron rod and the inner wall of the housing, and the second damping element is disposed between the resonator and the inner wall of the through hole; when the loudspeaker includes the iron cylinder, the first damping element is disposed between the iron cylinder and the inner wall of the housing, and the second damping element is disposed between the resonator and the inner wall of the through hole.

[0018] In some possible implementations, the outer periphery of the housing is provided with a decorative element, which includes a plastic part, a sticker, and a decorative metal piece; wherein the decorative metal piece is used to attach refrigerator magnets.

[0019] This application proposes a loudspeaker and an attached resonant acoustic device, which have the following advantages compared to the prior art:

[0020] In this loudspeaker, an adsorption surface is located on one side of the resonator. The adsorption surface is used to connect with the external medium surface (such as the surface of a plastic structure, glass plate, wall or tile plate, wooden tabletop, and metal structure). The resonator can vibrate according to the audio current. The vibration of the resonator will cause the medium surface to vibrate together, that is, resonate, to produce sound. This application improves the existing loudspeaker structure, eliminates the basket, and designs an adsorption surface for connecting with the medium surface, transferring the main body of sound production from the basket to the medium surface. In this way, the structural size of the loudspeaker can be greatly reduced, making it small, lightweight, and space-saving.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] like Figures 1-3 As shown, in a first aspect, this application provides a loudspeaker 1, which includes: a resonator 12 configured to vibrate in response to an audio current; the loudspeaker 1 has an adsorption surface 13 disposed on one side of the resonator 12.

[0039] The loudspeaker 1 also includes a voice coil 11, which is configured to be energized with an audio current to generate vibration; a resonator 12 is attached to one side of the voice coil 11 and resonates with the voice coil 11; and an adsorption surface 13 is provided on the side of the resonator 12 away from the voice coil 11.

[0040] Based on the above technical solution, in this loudspeaker 1, the resonator 12 is attached to one side of the voice coil 11, and the adsorption surface 13 is located on the side of the resonator 12 away from the voice coil 11. The adsorption surface 13 is used to contact the external medium surface (such as the surface of a plastic structure, a glass plate, a wall or tile plate, a wooden tabletop, and the surface of a metal structure). When an audio current is passed through the voice coil 11, it will vibrate, thereby driving the resonator 12 to vibrate together. The vibration of the resonator 12 will drive the medium surface to vibrate together, that is, resonate, so as to produce sound. This application improves the existing loudspeaker 1 structure, eliminates the basket frame, and designs an adsorption surface 13 for connecting with the medium surface, transferring the main body of sound production from the basket frame to the medium surface. In this way, not only can the structural size of the loudspeaker 1 be greatly reduced, so that it can be small, lightweight, and space-saving, but it can also be attached to the medium surface to ensure that it can produce beautiful sound.

[0041] A conventional speaker 1 includes a voice coil 11, a magnet, and a frame. When an audio current is passed through the voice coil 11, it generates a magnetic field. This magnetic field interacts with the magnetic field generated by the magnet. Consequently, the voice coil 11 is driven by the magnetic force of the magnet's magnetic field and vibrates relative to the magnet, thereby causing the frame to vibrate and producing sound.

[0042] Similar to the sound-generating principle of a traditional speaker 1, the voice coil 11 of this application generates a magnetic field when an audio current is passed through it, and this magnetic field also interacts with the magnetic field generated by the magnet.

[0043] The audio current mentioned in this application can refer to the current in the circuit when playing music. The volume, timbre, or sound quality of a song may vary at different times, that is, the strength of the audio current varies at different times. As a result, the magnetic field generated by the voice coil 11 will be different. The different strengths of the magnetic field at different times mean that the force exerted on the voice coil 11 by the magnetic field generated by the magnet is different at different times. The vibration amplitude of the voice coil 11 will be different, thus forming different sound waves. When these sound waves are transmitted to the surface of the medium, they will cause the surface of the medium to vibrate, and the vibration amplitude will be large or small, thus forming regular and beautiful music.

[0044] Unlike traditional speaker 1, the sound-emitting body of the speaker 1 in this application is not located on the speaker 1 itself, but on the medium surface in contact with the speaker 1. When not mounted on the medium surface, the sound emitted by the speaker 1 is very low-pitched. It should also be noted that different medium surfaces will have different frequencies at which they resonate due to their material properties, size, and temperature. Generally, hard medium surfaces produce the best sound, with wooden tabletops or sheet metal surfaces being the best. Soft medium surfaces can produce sound, but the sound quality will be relatively poor. Therefore, the speaker 1 in this application is generally used on hard medium surfaces.

[0045] Furthermore, the speaker 1 of this application can be adapted to the application scenario by selecting the material composition of the adsorption surface 13 to ensure that the speaker 1 can be tightly attached to the medium surface.

[0046] For example, if the adsorption surface 13 of this application is an adhesive surface, then the speaker 1 of this application can be attached to a wall, a wooden tabletop, or a flat furniture surface such as a microwave oven; if the adsorption surface 13 of this application is a magnetic surface, then the speaker 1 of this application can be attached to some furniture with metal shells such as a refrigerator; if the adsorption surface 13 of this application is a suction cup surface, then the speaker 1 of this application can be adsorbed and connected to some smooth flat surfaces such as mirrors, tile surfaces, etc.

[0047] The adhesive surface mentioned above can be achieved by applying glue or adhesive particles to the surface of the resonator 12, or by using double-sided adhesive tape.

[0048] In some embodiments, the side of the resonator 12 facing away from the voice coil 11 is coated with glue or adhesive particles to form an adhesive surface, that is, the resonator 12 and the adhesive surface are an integral structure. In this way, the resonator 12 is directly adsorbed and connected to the dielectric surface, so that the vibration of the voice coil 11 can be well transmitted to the dielectric surface, causing the dielectric surface to resonate, without excessive loss of vibration energy.

[0049] In some embodiments, the loudspeaker 1 further includes a double-sided adhesive tape, which is attached to the side of the resonator 12 away from the voice coil 11. The side of the double-sided adhesive tape away from the resonator 12 is the adhesive side. The double-sided adhesive tape can also make the resonator 12 tightly connected to the dielectric surface. And because the double-sided adhesive tape is plastic, it can fill the gap between the resonator 12 and the dielectric surface well when it is squeezed by the resonator 12 and the dielectric surface, so as to prevent vibration energy from being lost from these gaps.

[0050] Specifically, the thickness of the double-sided adhesive tape is 1.5mm-5mm. If the double-sided adhesive tape is too thick, a large portion of the vibration energy of the resonator 12 will be absorbed by the tape, resulting in very little vibration energy being transmitted to the dielectric surface. If the double-sided adhesive tape is too thin, firstly, processing is difficult, and secondly, the tape cannot effectively fill the gap between the resonator 12 and the dielectric surface, thus affecting vibration transmission and the sound output effect of the dielectric surface. In this application, the thickness of the double-sided adhesive tape is selected as 1.5mm-5mm to avoid the above-mentioned problems. Generally, the appropriate thickness of the double-sided adhesive tape is selected according to the outer diameter of the resonator 12. When the outer diameter of the resonator 12 is greater than or equal to 30mm, a double-sided adhesive tape with a thickness of 3mm-5mm can be selected; when the outer diameter of the resonator 12 is less than 30mm, a double-sided adhesive tape with a thickness of 1.5mm-3mm is generally selected.

[0051] In this application, the double-sided adhesive tape and the resonator 12 are designed as two separate structural components, which allows for the simultaneous processing and manufacturing of both the double-sided adhesive tape and the resonator 12, thereby shortening the construction period and accelerating production.

[0052] Furthermore, the voice coil 11 of the loudspeaker 1 in this application can also be called an inductor coil. Generally, the wire needs to be wound in a loop on the iron medium. When current is passed through it, a uniform and symmetrical magnetic field is generated. When it interacts with the magnetic field generated by the magnet, the vibration direction of the voice coil 11 can be determined according to the direction of the magnetic field.

[0053] The aforementioned statement indicates that wooden tabletops or sheet metal surfaces provide the best sound resonance. Therefore, the adsorption surface 13 of this application includes a magnetic surface, configured to adsorb and connect with the sheet metal surface or a magnetic surface. The speaker 1 is attached to the sheet metal surface or magnetic surface via the magnetic surface, such as the outer shell of a refrigerator. Moreover, compared to suction cups or adhesive surfaces, the magnetic surface of the speaker 1 "actively" adheres to the refrigerator surface. The speaker 1 will not detach from the refrigerator surface during vibration, ensuring that it can smoothly induce vibration and resonance in the refrigerator surface. Furthermore, it can be repeatedly attached to the refrigerator surface, or removed from it, without affecting its subsequent reattachment and resonance with the refrigerator.

[0054] Furthermore, the magnetic surface of this application can be indirectly attached to the iron sheet surface or a magnetic surface. That is, for some furniture, the outer shell is plastic and the inner structure is iron. Thus, the magnetic surface of this application can also be used to attach to these pieces of furniture.

[0055] In some embodiments, in order to ensure sound output effect, the area of ​​the medium surface should be greater than or equal to 5 times the area of ​​the adsorption surface 13. When the ratio of the area of ​​the medium surface to the area of ​​the adsorption surface 13 is (5-10):1, the sound output effect of the medium surface is the best.

[0056] In some embodiments, the resonator 12 has a magnetic surface, that is: the resonator 12 is made of magnetic material, or a magnetic material is coated on one side of the resonator 12 to form a magnetic surface; the resonator 12 has a magnetic surface, so that the connection between the resonator 12 and the medium surface will be more closely fitted, and the resonator 12 is "actively" adsorbed onto the medium surface, which is conducive to the resonator 12 transmitting vibration to the medium surface and causing the medium surface to resonate.

[0057] Alternatively, the speaker 1 may also include a magnetic patch 14, which is attached to the side of the resonator 12 away from the voice coil 11. The magnetic patch 14 has a magnetic surface and can be pressed onto one side of the resonator 12 using welding, adhesive, or high-pressure pressing techniques, so as to make the magnetic patch 14 and the resonator 12 as a whole as possible, so as to ensure that the vibration of the resonator 12 can be well transmitted to the medium surface.

[0058] The magnetic patch 14 is attached to the resonator 12. The process is simple and easy to operate. The magnetic patch 14 and the resonator 12 can be processed separately or simultaneously, which can reduce the manufacturing cycle.

[0059] Specifically, the magnetic patch 14 includes a soft magnetic patch 14 and a hard magnetic patch 14. The soft magnetic patch 14 is mainly made of neodymium iron boron soft magnetic material, strong soft magnetic material or ferrite soft magnetic material. The soft magnetic patch 14 is soft and flexible. When it comes into contact with the dielectric surface, it will deform to fill the gap between the resonator 12 and the dielectric surface, so that the resonator 12 and the dielectric surface are tightly attached. In this way, the vibration of the resonator 12 can be better transmitted to the dielectric surface. Similarly, the hard magnetic patch 14 is mainly made of ferrite magnetic material, strong magnetic material or neodymium iron boron magnetic material. However, because the hard magnetic patch 14 has a certain rigidity, it will not deform when it comes into contact with the dielectric surface. It cannot fully fill the gap between the resonator 12 and the dielectric surface. Therefore, the resonance effect of the dielectric surface is not as good as that of the soft magnetic patch 14.

[0060] In some embodiments, the resonator 12 includes a resonant diaphragm, analogous to the diaphragm of a conventional speaker 1. In a conventional speaker 1, one side of the diaphragm is connected to the voice coil 11, and the other side is connected to the frame. The frame has a paper diaphragm. The vibration of the diaphragm causes the paper diaphragm on the frame to vibrate, thereby producing sound. Therefore, in this application, the resonant diaphragm is connected to the voice coil 11 on one side and to the medium surface on the other side. The vibration of the resonant diaphragm causes the medium surface to resonate, thereby producing sound. In other words, the resonant diaphragm better transmits the vibration of the voice coil 11 to the medium surface, so that the medium surface can produce a better sound. Without the resonant diaphragm, the voice coil 11 directly contacts the medium surface, which will affect the vibration of the medium surface to some extent, resulting in a poor sound effect.

[0061] Furthermore, the radius of the resonant diaphragm in this application is equal to the radius of the voice coil 11, but it can also be slightly larger or slightly smaller than the radius of the voice coil 11. In this way, the resonant diaphragm can transmit vibrations in the best way.

[0062] In some embodiments, the loudspeaker 1 further includes a first magnet 15 and an iron rod 16; the first magnet 15 is sleeved on the outer periphery of the iron rod 16, the voice coil 11 is disposed on one side of the first magnet 15, and the resonator 12 is located on the side of the voice coil 11 away from the first magnet 15; or, the loudspeaker 1 further includes a second magnet 17 and an iron cylinder 18; the second magnet 17 is disposed inside the iron cylinder 18, the voice coil 11 is disposed on one side of the second magnet 17, and the resonator 12 is located on the side of the voice coil 11 away from the second magnet 17.

[0063] Both the first magnet 15 and the second magnet 17 can generate a constant magnetic field. When an audio current is passed through the voice coil 11, it will also generate a magnetic field. In this way, the magnetic fields of the first magnet 15 or the second magnet 17 and the magnetic field of the voice coil 11 will interact. The magnetic field of the first magnet 15 or the second magnet 17 will drive the voice coil 11 to move. Since the strength of the magnetic field of the voice coil 11 changes at any time, the magnetic field of the first magnet 15 or the second magnet 17 will drive the voice coil 11 to move back and forth, so that the voice coil 11 vibrates, thereby driving the resonator 12 to vibrate, and then driving the medium surface to vibrate, thus realizing the sound emission.

[0064] The loudspeaker 1 of this application can also be a magnetostrictive rare-earth loudspeaker, an electromagnetically driven loudspeaker, or a vibrating loudspeaker. All magnetostrictive rare-earth loudspeakers, electromagnetically driven loudspeakers, or vibrating loudspeakers include a resonator 12. Then, the resonator 12 of these loudspeakers is connected to the medium surface, which can also make the medium surface vibrate and produce sound.

[0065] Magnetostrictive rare-earth horns, electromagnetically driven horns, or vibrating horns are all existing structures, and their sound-generating principles will not be described here.

[0066] In this application, when the loudspeaker 1 includes a first magnet 15, an iron rod 16, a voice coil 11, and a resonator 12, the center lines of the iron rod 16, the first magnet 15, the voice coil 11, and the resonator 12 all coincide; or, when the loudspeaker 1 includes a second magnet 17 and an iron cylinder 18, the center lines of the iron cylinder 18, the second magnet 17, the voice coil 11, and the resonator 12 all coincide.

[0067] In this way, the vibration of the voice coil 11 and the vibration of the resonator 12 can be kept consistent, and the voice coil 11 and the resonator 12 can be controlled to vibrate in the same direction. When resonance occurs on the dielectric surface, the position between the voice coil 11 and the resonator 12 will not be affected.

[0068] like Figures 4-12As shown, in a second aspect, this application also proposes an attached resonant speaker 100, which includes a housing 2 and a speaker 1 as described in the first aspect; a through hole 21 is provided on one side of the housing 2; the speaker 1 includes a resonator 12, which is configured to vibrate to extend out of or retract into the through hole 21.

[0069] This attached resonant speaker 100 uses the aforementioned speaker 1. The adsorption surface 13 of the speaker 1 passes through the through hole 21 and is connected to the medium surface. When the speaker 1 vibrates, it causes the medium surface to resonate and produce sound. This attached resonant speaker 100 eliminates the need for a frame, greatly reducing its size, so as to develop towards miniaturization and portability, in order to meet people's pursuit of beautiful sound effects and easy portability.

[0070] In some embodiments, the housing 2 has a resonant cavity 22 defined inside, and the resonant cavity 22 is connected to the through hole 21; the speaker 1 includes a first magnet 15 and an iron rod 16, both of which are located inside the resonant cavity 22; or, the speaker 1 includes a second magnet 17 and an iron cylinder 18, both of which are located inside the resonant cavity 22.

[0071] Specifically, the housing 2 is provided with a first damping member 23 and a second damping member 24 inside; when the loudspeaker 1 includes an iron rod 16, the first damping member 23 is disposed between the iron rod 16 and the inner wall of the housing 2, and the second damping member 24 is disposed between the resonator 12 and the inner wall of the through hole 21; when the loudspeaker 1 includes an iron cylinder 18, the first damping member 23 is disposed between the iron cylinder 18 and the inner wall of the housing 2, and the second damping member 24 is disposed between the resonator 12 and the inner wall of the through hole 21.

[0072] The first damping component 23 is used to reduce the transmission of vibration to the inner wall of the housing 2, and the second damping component 24 is used to reduce the transmission of vibration to the inner wall of the through hole 21, i.e., between the housings 2, so as to ensure that the vibration can be transmitted to the medium surface and ensure the sound effect.

[0073] In addition, the first damping member 23 and / or the second damping member 24 can reduce the transmission of vibration energy to the housing 2, so that the vibration of the housing 2 will be very slight, and the housing 2 will not vibrate relative to the medium surface or fall off the medium surface.

[0074] In this application, the first damping element 23 and / or the second damping element 24 include damping foam, which has good anti-plasticity and can effectively absorb vibration to prevent the housing 2 from vibrating; the first damping element 23 and / or the second damping element 24 may also include a flexible silicone partition and EVA strip.

[0075] Furthermore, the second damping member 24 includes an annular damping member. The second damping member 24 is sleeved on the outer periphery of the resonator 12 and contacts the inner sidewall of the through hole 21. The annular damping member is designed to fit the outer contour of the resonator 12 so as to fully fill the gap between the resonator 12 and the inner sidewall of the through hole 21 and prevent the resonator 12 from transmitting vibration to the housing 2.

[0076] Furthermore, the inner diameter of the through hole 21 is designed to match the outer diameter of the resonator 12, ensuring that the resonator 12's insertion and extension are not obstructed. Simultaneously, it must ensure that there are no gaps between the resonator 12 and the inner wall of the through hole 21. If gaps exist between the resonator 12 and the inner wall of the through hole 21, sound waves will directly escape through these gaps, resulting in poor sound quality. In this application, the outer diameter of the resonator 12 is 15mm-50mm, and the inner diameter of the through hole 21 is 15mm-50mm, preferably 30mm-50mm.

[0077] In some embodiments, the wall portion of the housing 2 surrounding the through hole 21 protrudes outward to form an annular flange 25. The second damping member 24 is sealed to the annular flange 25. When the resonant speaker 100 of this application is mounted on a bathroom mirror, the annular flange 25 can prevent water from entering the through hole 21 to protect the safety of the internal circuit of the housing 2. This can prevent bath water from entering the resonant cavity 22 of the housing 2 through the through hole 21 when the resonant speaker 100 is used in a bathroom environment.

[0078] The overall shape of the shell 2 is a cuboid or cube structure. The corners of the shell 2 are provided with rounded transition surfaces to avoid damage and breakage of the corners when the shell 2 collides with external objects, and to avoid potential safety hazards to users caused by sharp corners.

[0079] In some embodiments, the housing 2 includes an upper housing 26 and a lower housing 27, which are detachably connected; the lower housing 27 has a through hole 21 and an annular flange 25.

[0080] The upper housing 26 and the lower housing 27 can be connected by snap-fit ​​or by thread to facilitate disassembly of the upper housing 26 and the lower housing 27 for maintenance, or to install the upper housing 26 and the lower housing 27 for subsequent use.

[0081] The connection or mating parts of the upper housing 26 and the lower housing 27 must be equipped with a waterproof structure to prevent bath water from entering the resonance cavity 22 of the housing 2 when the resonant speaker 100 is used in a bathroom environment.

[0082] In this application, the upper shell 26 and the lower shell 27 are both made of ABS plastic (acrylonitrile-butadiene-styrene copolymer). ABS plastic has good wear-reducing and abrasion-resistant properties, and can be impact-resistant, heat-resistant and flame-retardant. Using it as the upper shell 26 and the lower shell 27 can ensure the structural stability of the upper shell 26 and the lower shell 27 and improve the service life of the upper shell 26 and the lower shell 27.

[0083] Accordingly, the first damping component 23 is disposed in the upper housing 26, and the second damping component 24 is disposed in the lower housing 27. The first damping component 23 and the second damping component 24 can respectively reduce the impact of the vibration of the upper housing 26 and the lower housing 27 on the sound effect of the resonant speaker 100. A buffer pad 272 is also provided on the lower housing 27. The buffer pad 272 includes a flexible silicone partition, EVA strip, etc., which are also used to reduce the vibration of the housing 2.

[0084] A decorative element 29 is provided on the outer periphery of the housing 2. The decorative element 29 includes a plastic part, a sticker, and a decorative iron sheet; wherein, the decorative iron sheet is used to attach refrigerator magnets. Specifically, a decorative element 29 is also provided on the upper housing 26. The decorative element 29 can be a plastic part or a sticker to improve the appearance of the resonant speaker 100. The decorative element 29 can also be a decorative iron sheet.
