Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making creative efforts shall fall within the protection scope of the present application.

As illustrated in fig. 1-3, the present embodiment proposes, in a first aspect, a loudspeaker 1, comprising: a resonating body 12 configured to vibrate in accordance with an audio current and accordingly; the loudspeaker 1 has an adhesive surface 13, and the adhesive surface 13 is disposed on one side of the resonator 12.

The present speaker 1 further includes a voice coil 11, the voice coil 11 being configured to be energized with an audio current to generate vibrations; the resonance body 12 is attached to one side surface of the voice coil 11 and resonates with the voice coil 11; the adhesive surface 13 is provided on the side of the resonator body 12 facing away from the voice coil 11.

Based on the above technical solution, the resonator 12 is attached to a side surface of the voice coil 11, the adhesive surface 13 is disposed on a side of the resonator 12 away from the voice coil 11, the adhesive surface 13 is used for contacting with an external medium surface (such as a surface of a plastic structure, a glass plate surface, a wall or a tile plate surface, a wooden table surface, a surface of a metal structure, etc.), the voice coil 11 vibrates when being energized with an audio current to drive the resonator 12 to vibrate together, and the resonator 12 vibrates to drive the medium surface to vibrate together, i.e., resonate together, so as to generate a sound; this application has improved current speaker 1 structure, has removed the basin frame from, and has designed a sticky surface 13 and be used for being connected with the medium face, and the main part that will make a sound shifts to the medium face by the basin frame, like this, not only can dwindle the structure size of speaker 1 greatly to can accomplish small-size lightly, not account for the space, can laminate with the medium face moreover, guarantee to send graceful vocal music.

Like the sound production principle of the conventional audio speaker 1, the voice coil 11 of the present application generates a magnetic field when supplied with an audio current, and this magnetic field also interacts with the magnetic field generated by the magnet.

The audio current mentioned in the present application may refer to a current in a circuit when music is played, and a song may have different volume, tone or tone quality at different times, that is, the strength of the audio current at different times is different, so that the magnetic field generated by the voice coil 11 is different, the strength of the magnetic field at different times is different, that is, the force of the magnetic field generated by the magnet is different at different times, and the vibration amplitudes of the voice coil 11 are different, thereby forming different sound waves, and when the sound waves are transmitted to the medium surface, the medium surface is caused to vibrate, and the vibration amplitudes are large or small, so that regular and beautiful music can be formed.

Unlike the conventional audio speaker 1, the speaker 1 of the present application has a sound emission main body not on the speaker 1 but on a medium surface in contact with the speaker 1; when not mounted on a medium surface, the sound of the loudspeaker 1 is very low. It should be noted here that, different dielectric surfaces have different frequencies when the dielectric surfaces reach resonance due to their material characteristics, sizes, temperatures of the dielectric surfaces, and the like, and in general, the sound production effect of the hard dielectric surface is the best, wherein the soft dielectric surface can produce sound with the best effect on the surface of a wooden tabletop or iron sheet, but the sound production effect is relatively poor, and thus, the speaker 1 of the present application is generally used on the hard dielectric surface.

The adhesive surface 13 of the present application can be connected to a wall surface, a wooden table surface or a flat furniture surface, and the speaker 1 of the present application can be attached to a microwave oven.

In addition, the voice coil 11 of the speaker 1 of the present application, which may also be referred to as an inductance coil, generally requires an electric wire to be annularly wound around an iron medium, and when a current is applied, a uniform and symmetrical magnetic field is generated, and when the electric wire interacts with a magnetic field generated by a magnet, the vibration direction of the voice coil 11 is determined according to the magnetic field direction, and the voice coil 11 is controlled to stably vibrate and not to move relative to the magnet due to vibration.

In some embodiments, a side of the resonator 12 away from the voice coil 11 is coated with glue or adhesive particles to form the adhesive surface 13, that is, the resonator 12 and the adhesive surface 13 are an integral structure, so that the resonator 12 is directly connected to the medium surface in an absorption manner, so that the vibration of the voice coil 11 can be well transmitted to the medium surface to cause the medium surface to resonate without excessive vibration energy loss.

In some embodiments, the speaker 1 further includes a double-sided tape 14, the double-sided tape 14 is attached to a side of the resonator 12 away from the voice coil 11, a side of the double-sided tape 14 away from the resonator 12 is an adhesive surface 13, the double-sided tape 14 can also tightly connect the resonator 12 and the dielectric surface, and because the double-sided tape 14 has plasticity, when the resonator 12 and the dielectric surface are squeezed each other, gaps between the resonator 12 and the dielectric surface can be filled well, so as to prevent vibration energy from losing from the gaps.

Specifically, the thickness of the double-sided adhesive tape 14 is 1.5mm to 5mm, if the double-sided adhesive tape 14 is too thick, most of the vibration energy of the resonator 12 is absorbed by the double-sided adhesive tape 14, so that the vibration energy transmitted to the medium surface is less, if the double-sided adhesive tape 14 is too thin, firstly, the processing difficulty is high, secondly, the double-sided adhesive tape 14 cannot well fill the gap between the resonator 12 and the medium surface, and thus, the transmission of the vibration is also influenced, and the sound output effect of the medium surface is influenced. In the present application, the thickness of the double-sided adhesive sticker 14 is selected to be 1.5mm to 5mm to avoid the above-mentioned problems; generally, the double-faced adhesive tape 14 with a suitable thickness is selected according to the outer diameter of the resonance body 12, when the outer diameter of the resonance body 12 is greater than or equal to 30mm, the double-faced adhesive tape 14 with a thickness of 3mm-5mm can be selected, and when the outer diameter of the resonance body 12 is less than 30mm, the double-faced adhesive tape 14 with a thickness of 1.5mm-3mm is generally selected.

In the present application, the double-sided adhesive tape 14 and the resonant body 12 are separately designed into 2 structural members, so that the double-sided adhesive tape 14 and the resonant body 12 can be processed and manufactured simultaneously, thereby shortening the construction period and speeding up the production.

In some embodiments, the resonant body 12 includes a resonant diaphragm, similar to the diaphragm of the conventional audio speaker 1, one side of the diaphragm of the conventional audio speaker 1 is connected to the voice coil 11, the other side of the diaphragm is connected to the frame, and the frame has a paper film thereon, and the diaphragm vibrates to drive the paper film on the frame to vibrate to generate sound, so that the resonant diaphragm of the present application is connected to the voice coil 11 on one side and to the medium surface on the other side, and vibrates to drive the medium surface to resonate to generate sound; so to say, the resonant diaphragm transmits the vibration of the voice coil 11 to the medium surface better, so that the medium surface can make a better sound; if there is no resonant diaphragm, the voice coil 11 directly contacts the medium surface, so that the vibration of the medium surface is more or less affected, 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 11, but may be slightly larger or slightly smaller than the radius of the voice coil 11, so that the effect of the resonant diaphragm in transmitting vibration is best.

In some embodiments, the loudspeaker 1 further comprises a first magnet 15 and an iron rod 16; the first magnet 15 is sleeved on the periphery of the iron rod 16, the voice coil 11 is arranged on one side of the first magnet 15, and the resonance body 12 is arranged on one side of the voice coil 11 departing from the first magnet 15; alternatively, the speaker 1 further includes a second magnet 17 and an iron cylinder 18; the second magnet 17 is arranged inside the iron cylinder 18, the voice coil 11 is arranged on one side of the second magnet 17, and the resonant body 12 is arranged on one side of the voice coil 11, which is far away from the second magnet 17.

The first magnet 15 or the second magnet 17 can generate a constant magnetic field, and the voice coil 11 can also generate a magnetic field after being energized with an audio current, so that the magnetic field of the first magnet 15 or the second magnet 17 interacts with the magnetic field of the voice coil 11, the magnetic field of the first magnet 15 or the second magnet 17 pushes the voice coil 11 to move, and the strength of the magnetic field of the voice coil 11 can change at any time, so that the magnetic field of the first magnet 15 or the second magnet 17 pushes the voice coil 11 to move back and forth, that is, the voice coil 11 vibrates to drive the resonator 12 to vibrate, and further drive the dielectric surface to vibrate, and sound emission is realized.

The utility model provides a speaker 1 also can adopt magnetostrictive rare earth loudspeaker, electromagnetic drive loudspeaker or vibrations loudspeaker, and magnetostrictive rare earth loudspeaker, electromagnetic drive loudspeaker or vibrations loudspeaker all include resonance body 12, and resonance body 12 of these structures is connected with the medium face again, can make medium face vibration, sound production equally.

The magnetostrictive rare earth horn, the electromagnetic driving horn or the vibration horn are all of the existing structures, and the sound production principle of the magnetostrictive rare earth horn, the electromagnetic driving horn or the vibration horn is not described here.

Further, the center lines of the iron rod 16, the first magnet 15, the voice coil 11, and the resonator 12 all coincide; alternatively, the center lines of the iron cylinder 18, the second magnet 17, the voice coil 11, and the resonator 12 all coincide.

In this way, it is possible to ensure that the vibration of the voice coil 11 and the vibration of the resonating body 12 coincide, and to control the voice coil 11 and the resonating body 12 to vibrate in the same direction, and when the medium-plane resonance is caused, the position between the voice coil 11 and the resonating body 12 is not affected, that is, the voice coil 11 is not displaced with respect to the resonating body 12 and the first magnet 15 or the second magnet 17.
