As shown in fig. 1 to 11, the present embodiment proposes an attached resonance sound box, which includes a housing 1, a speaker 2, and an adsorption member 3; one side of the shell 1 is provided with a through hole 11; the loudspeaker 2 comprises a resonance body 21, wherein the resonance body 21 is arranged to extend out of the shell 1 through the through hole 11, namely, the resonance body 21 vibrates and can extend out of the through hole 11 or retract into the through hole 11; the adsorbing member 3 has an adsorbing surface 31, the adsorbing member 3 is disposed on the casing 1, and the adsorbing surface 31 and the through hole 11 are located on the same side of the casing 1.

Based on the technical scheme, the adsorption piece 3 is arranged on the shell 1, the adsorption piece 3 is provided with an adsorption surface 31, one side of the shell 1 is provided with the through hole 11, the adsorption surface 31 and the through hole 11 are positioned on the same side of the shell 1, and the adsorption surface 31 is used for adsorption connection with an external medium surface (such as a plastic structure surface, a glass plate surface, a wall or ceramic tile plate surface, a wooden table surface and a metal structure surface) so as to realize that the resonance sound box is attached to the medium surface; the resonant body 21 vibrates, and can extend out of the through hole 11 or retract into the through hole 11, and causes the medium surfaces to vibrate together to realize resonance so as to make sound; the utility model provides a resonance stereo set has designed a structure of called absorption piece 3 for this resonance stereo set can conveniently adsorb with the medium face and be connected, and can adsorb with the medium face of different grade type (like plastic structure surface, glass face, wall or ceramic tile face, wooden desktop and metal structure surface) and be connected, here, has enlarged this resonance stereo set's application scope, in order to satisfy the audio playback demand of user under specific sight (like bathroom, kitchen etc.).

In some embodiments, the adsorbing member 3 includes a magnetic member (as shown in fig. 4, fig. 5, fig. 7, fig. 8, and fig. 11) and a suction cup (not shown in the drawings), both of which have an adsorbing surface 31, some furniture, such as a refrigerator, a toilet glass, or a mirror in a bathroom, the refrigerator has a very flat iron sheet surface with a large area, the magnetic member can be attached to the iron sheet surface of the refrigerator in an adsorbing manner, so that the resonant body 21 can cause the iron sheet surface to resonate and generate sound, and the suction cup can be attached to the smooth mirror surface in an adsorbing manner, so that the resonant body 21 can cause the smooth mirror surface to resonate and generate sound.

The principle that the magnetic suction piece is adsorbed on the iron sheet surface of the refrigerator is as follows: the principle that magnets attract each other in opposite directions; the principle that the sucker is adsorbed on the smooth mirror surface is as follows: the sucker is pressed on the smooth mirror surface to exhaust air between the sucker and the smooth mirror surface to the greatest extent, no air exists between the sucker and the smooth mirror surface, the pressure intensity is small, and the pressure difference between the sucker and the atmospheric pressure is large, so that the sucker is tightly pressed on the smooth mirror surface under the action of the pressure difference.

This application can be according to the material characteristic of the attached medium face of will, the structure of adsorption component 3 is designed adaptively, for example, to some walls, can not adopt magnetism to inhale piece or sucking disc, but can adopt the double faced adhesive tape to paste, and the double faced adhesive tape pastes and connects in one side of resonance body 21, and the wall can be connected to the opposite side that the double faced adhesive tape pasted, and like this, the resonance stereo set of this application alright attached on the wall can arouse wall resonance, realize the sound production.

In some embodiments, the magnetic member includes a ring magnet, the ring magnet is sleeved on the periphery of the through hole 11, and a side of the ring magnet facing away from the housing 1 is an absorption surface 31; or, the magnetic part includes a plurality of magnets, the magnets surround the periphery of the through hole 11, and one side of the magnets departing from the casing 1 is an adsorption surface 31.

The periphery of through-hole 11 is located to the ring magnet cover, or a plurality of magnets encircle and distribute in the periphery of through-hole 11 to, when attaching this resonance stereo set on the iron sheet surface, ring magnet or magnet and iron sheet surface between magnetic field force encircle in the periphery of through-hole 11, thereby, the surface of the resonance body 21 can fully contact the iron sheet surface, certain perk can not appear, with this, guarantee that the vibration of the resonance body 21 can transmit for the iron sheet surface well, in order to arouse iron sheet surface resonance, the sound production.

Furthermore, the annular magnet is concentric with the center of the through hole 11, or a plurality of magnets are uniformly distributed around the periphery of the through hole 11, so that the magnetic field force between the annular magnet or the magnet and the surface of the iron sheet is symmetrically distributed around the periphery of the through hole 11, and thus, when the resonance body 21 resonates with the surface of the iron sheet, the influence of the surface of the iron sheet on the resonance body 21 is minimal, and the vibration of the resonance body 21 cannot deviate relative to the through hole 11; here, the ring magnet is concentric with the center of the through hole 11, or a plurality of magnets are uniformly distributed around the periphery of the through hole 11, which can improve the stability of the speaker 2, so that the speaker 2 can stably vibrate and cause surface resonance of the iron sheet.

In some embodiments, the resonant body 21 includes a resonant diaphragm, similar to the diaphragm of the conventional audio speaker 2, one side of the diaphragm of the conventional audio speaker 2 is connected to the voice coil 22, and the other side is connected to the frame, and the frame has a paper film thereon, and the vibration of the diaphragm drives the paper film on the frame to vibrate to generate sound, so that one side of the resonant diaphragm of the present application is connected to the voice coil 22, and the other side is connected to the medium surface, and the resonant diaphragm vibrates to drive the medium surface to resonate to generate sound; as such, the resonant diaphragm is used to better transmit the vibration of the voice coil 22 to the medium surface, so that the medium surface can make a better sound; without the resonant diaphragm, the voice coil 22 directly contacts the medium surface, so that the vibration of the medium surface is affected more or less, and the sound production effect is not good enough.

Further, the radius of the resonant diaphragm of the present application is equal to the radius of the voice coil 22, but may be slightly larger or slightly smaller than the radius of the voice coil 22, so that the effect of the resonant diaphragm in transmitting vibration is best.

In some embodiments, the speaker 2 further includes a voice coil 22, a sound producing magnet 23, and a ferrous medium (not shown in the drawings); the iron medium comprises an iron rod and an iron cylinder; generally, sounding magnet 23 is provided on one side of voice coil 22, resonator 21 is attached to the other side of voice coil 22, and the iron medium is located on the other side of sounding magnet 23.

Similar to the sounding principle of the conventional audio speaker 2, the voice coil 22 of the present application generates a magnetic field when an audio current is applied thereto, and the magnetic field interacts with the magnetic field generated by the sounding magnet 23.

The audio current referred to in this application may refer to the current in the circuit when playing music, and a song may have different volume, tone or tone quality at different times, i.e. the strength of the audio current at different times is different, so that the magnetic field generated by the voice coil 22 will be different, and the strength of the magnetic field at different times will be different, i.e. the voice coil 22 will be affected by the force of the magnetic field generated by the sounding magnet 23 at different times, and the vibration amplitudes of the voice coil 22 will be different, thereby forming different sound waves, which will cause the medium surface to vibrate and the vibration amplitudes will be different when being transmitted to the medium surface, so that regular and beautiful music can be formed.

Unlike the conventional speaker 2, the speaker 2 of the present application has a sound emission main body not on the speaker 2 but on a medium surface in contact with the speaker 2; when the resonant sound is not attached to the medium surface, the sound of the speaker 2 is very low. It should be noted here that, different medium surfaces have different frequencies when the medium surfaces reach resonance due to their material characteristics, sizes, temperatures of the medium surfaces, and the like, and in general, the sound production effect of the hard medium surface is the best, wherein the soft medium surface can produce sound with the best effect on a wooden table top or an iron sheet surface, but the sound effect is relatively poor, so the speaker 2 of the present application is generally used on the hard medium surface.

Furthermore, the material of the absorbing member 3 of the speaker 2 of the present application can be selected according to the application scenario, so as to ensure that the speaker 2 can be tightly attached to the medium surface.

In addition, the voice coil 22 of the speaker 2 of the present application, which may also be referred to as an inductor, generally requires an electric wire to be annularly wound around an iron medium, and generates a uniform and symmetrical magnetic field when a current is applied thereto, and determines the vibration direction of the voice coil 22 according to the magnetic field direction when interacting with the magnetic field generated by the sounding magnet 23.

Further, a first shock absorbing member 12 and a second shock absorbing member 13 are arranged inside the shell 1; the first shock absorber 12 is arranged between the sounding magnet 23 and the inner side wall of the shell 1; the second damper 13 is provided between the resonator body 21 and the inner sidewall of the through-hole 11.

First damper 12 is used for slowing down the vibration of voice coil 22 and transmits toward the inside wall of casing 1 to slow down the energy of voice coil 22 vibration and transmit toward casing 1, and second damper 13 is used for slowing down the vibration of voice coil 22 and transmits toward the inside wall of through-hole 11 casing 1 promptly, and the energy of slowing down the vibration of voice coil 22 transmits toward casing 1, thereby, reduces the loss of vibration energy, makes the energy transmission of more vibrations for the medium face.

In addition, the vibration energy transmitted to the housing 1 is reduced, and the vibration of the housing 1 is slight, so that the housing 1 does not vibrate relative to the medium surface and fall off from the medium surface.

In the present application, the first damper 12 and/or the second damper 13 comprise a damping foam having good resistance to plastic deformation, which can absorb vibration well to prevent the housing 1 from vibrating.

In some embodiments, the wall of the housing 1 surrounding the through hole 11 protrudes outward to form an annular flange 14, and the second damper 13 is hermetically connected to the annular flange 14, so that when the resonance sound box of the present application is attached to a mirror of a bathroom, the annular flange 14 can block moisture from entering the through hole 11 to protect the safety of the circuit inside the housing 1.

In some embodiments, the housing 1 comprises an upper housing 15 and a lower housing 16, the upper housing 15 and the lower housing 16 being detachably connected; the lower housing 16 is formed with a through hole 11 and an annular flange 14.
