The damping function of current audio amplifier is through increasing the mounting in each junction of box, and the mode of isolated loudspeaker and the resonance of support improves, but this kind of mode can not solve the loudspeaker vibration problem of audio amplifier fundamentally, uses the back when the audio amplifier is long-time, still can appear the audio amplifier can send the problem of noise when the sound production.

In order to solve the above problem, an embodiment of the present disclosure provides a sound box.

With reference to fig. 1-3, an embodiment of the present disclosure provides a sound box, which includes a box body 1 and more than or equal to three sounding portions.

As shown in fig. 1 and 2, the case 1 has a rectangular parallelepiped shape, and it is understood that the case 1 may have any other shape.

As shown in fig. 3, the box 1 includes a front shell 101 and a rear shell 102, the front shell 101 and the rear shell 102 are connected to each other, and the connection mode may be a detachable fixed connection, for example, the connection mode may be fixed connection through a corresponding slot and a corresponding latch, and may also be fixed connection through a fixing bolt and a nut. The front case 101 and the rear case 102 form a closed hollow inner cavity therebetween, and the front case 101 and the rear case 102 form a first sidewall and a second sidewall which are oppositely arranged, respectively.

Like this, preceding shell 101 and backshell 102's detachable fixed connection had both guaranteed that the audio amplifier is in normal operating conditions, and preceding shell 101 and backshell 102 can be stable link together, can not lead to the structure to receive the influence because of the vibration of first sound production portion 2, make the closure of inner space suffer destruction, influence other sound production of sound production portion, overhauld and change when having made things convenient for later stage sound production portion to go wrong again.

The front case 101 and the rear case 102 are each provided with a sound-emitting portion mounting hole for mounting a sound-emitting portion.

Alternatively, the shape and size of the sound-emitting portion mounting hole correspond to those of the sound-emitting portion therein, for example, the sound-emitting portion may be circular, rectangular, elliptical, or the like, and correspondingly, the sound-emitting portion mounting hole may be circular, rectangular, elliptical, or the like. Alternatively, the first sounding part mounting hole may be circular in shape, and the second and third sounding part mounting holes may be rectangular in shape, wherein the first sounding part 2 is located in the first sounding part mounting hole, the second sounding part 3 is located in the second sounding part mounting hole, and the third sounding part 4 is located in the third sounding part mounting hole; the first sound-emitting portion mounting hole may be formed in an elliptical shape, and the second sound-emitting portion mounting hole and the third sound-emitting portion mounting hole may be formed in a circular shape.

Alternatively, the number of the sounding portions may be three, four, five or more, and correspondingly, the number of the sounding portion mounting holes may be three, four, five or more, in the case where the case 1 is provided with three sounding portion mounting holes in the drawing, the corresponding sounding portions are mounted in the sounding portion mounting holes, the front case 101 is provided with two circular sounding portion mounting holes, and the rear case 102 is provided with one circular sounding portion mounting hole. Wherein, the sound-emitting part comprises a first sound-emitting part 2, a second sound-emitting part 3 and a third sound-emitting part 4, the first sound-emitting part 2 is arranged in the first sound-emitting part mounting hole of the front shell 101, the second sound-emitting part 3 is arranged in the second sound-emitting part mounting hole of the front shell 101, and the third sound-emitting part 4 is arranged in the third sound-emitting part mounting hole of the rear shell 102.

Thus, when the first sound-emitting part 2 emits sound, the air inside the box body 1 is compressed, the second sound-emitting part 3 and the third sound-emitting part 4 are driven to vibrate, and the front shell 101 and the rear shell 102 are both provided with the sound-emitting parts, so that the vibration of the sound-emitting parts on the front shell 101 and the rear shell 102 can be mutually offset, the box body 1 can not be driven to vibrate, and the sound box can not generate noise. Meanwhile, the sound box can be combined with the sound-emitting parts under various conditions by arranging the sound-emitting part mounting holes in various shapes and in various quantities, so that the applicability of the sound box is improved.

Optionally, the number of the sound-emitting portions and the sound-emitting portion mounting holes may also be five, for example, the front shell 101 of the box 1 is provided with three sound-emitting portion mounting holes, and the rear shell 102 of the box 1 is provided with two sound-emitting portion mounting holes, wherein the sound-emitting portions include a first sound-emitting portion 2, a second sound-emitting portion 3, a third sound-emitting portion 4, a fourth sound-emitting portion (not shown in the figure), and a fifth sound-emitting portion (not shown in the figure). The first, second and third sound emitting portions 2, 3 and 4 are provided in the same manner as in the above-described embodiment in which the case 1 is provided with three sound emitting portion mounting holes, and one of the fourth and fifth sound emitting portions is provided in the sound emitting portion mounting hole of the front case 101 and the other is provided in the sound emitting portion mounting hole of the rear case 102.

Alternatively, the third sound-emitting portion 4 provided on the rear case 102 corresponds to the position of the second sound-emitting portion 3 provided on the front case 101.

Thus, when the first sound-emitting part 2 emits sound and vibrates, the third sound-emitting part 4 can better offset the vibration of the sound box caused by the sound and vibration of the second sound-emitting part 3, and the sound box is ensured to have better vibration and noise reduction capability.

Alternatively, the third sound-emitting portion 4 provided on the rear case 102 is the same shape as the second sound-emitting portion 3 provided on the front case 101.

Thus, since the second sound-emitting portion 3 and the third sound-emitting portion 4 have the same shape, when the first sound-emitting portion 2 emits sound and vibrates, the second sound-emitting portion 3 and the third sound-emitting portion 4 are driven to generate the same vibration, and the third sound-emitting portion 4 can better cancel the vibration of the sound box caused by the sound-emitting vibration of the second sound-emitting portion 3, so that the sound box is not moved any more, and the vibration-eliminating and noise-reducing capabilities of the sound box are improved.

Alternatively, the third sound-emitting portion 4 provided on the rear case 102 has the same weight as the second sound-emitting portion 3 provided on the front case 101.

Like this, because the weight of second sound production portion 3 is the same with third sound production portion 4, when first sound production portion 2 vocal vibration, the vibration frequency of second sound production portion 3 that arouses also can be the same with third sound production portion 4, third sound production portion 4 just can be better offset the vibration of the audio amplifier that arouses by the vocal vibration of second sound production portion 3, make the audio amplifier no longer produce and remove, improved the ability of audio amplifier vibration elimination noise reduction, bring better experience for the user.

Alternatively, as shown in fig. 4-6, the first sound-generating part 2 is a speaker having an active sound-generating capability, for example, the speaker may be a moving coil speaker, an inductive speaker, an electrostatic speaker, a planar speaker, a ribbon speaker, a horn speaker, etc., and the speaker in fig. 4 is a moving coil speaker. The moving-coil speaker includes: a vibrating structure, a support structure and a magnet 207. The vibrating structure comprises a suspension edge 203, a corrugated rim 204, a vibrating diaphragm 205, a centering support piece 206, a dust cover 208 and a voice coil 209, and the supporting structure comprises a basin stand 201 and a pressing edge 202. Fig. 4 to 6 show a preferred embodiment of the first sound-emitting part 2 of the present invention, however, the present invention is not limited thereto, and other forms of speakers that emit sound by vibration of the diaphragm 205 may be adopted as the first sound-emitting part 2.

In the vibration structure, the suspension edge 203 is a circular ring structure with the outer edge of the corrugated rim 204 extending axially, the outer edge of the suspension edge 203 is connected to the basin frame 201, the radial outer edge of the corrugated rim 204 is connected to the suspension edge 203, and the radial inner edge of the corrugated rim 204 is connected to the diaphragm 205. The inner rim of the diaphragm 205 is connected to a voice coil 209, the upper part of the voice coil 209 being located in the bottom of the basin stand 201, and the lower part of the voice coil 209 being suspended in the magnet 207. The centering support piece 206 is of a water wave-shaped structure, is positioned between the vibrating diaphragm 205 and the basin frame 201, is connected with the basin frame 201, and is used for providing restoring force for the vibration of the vibrating diaphragm 205; a dust cover 208 covers the surface of the diaphragm 205, the outer edge of the dust cover 208 is connected to the inner edge of the corrugated rim 204, and the dust cover 208 prevents dust from entering the speaker.

The basin stand 201 is a single framework for mounting other components.

The edge press 202 is a frame having a hollow inner cavity for connecting the tub 201 and the case 1.

Thus, when an electrical signal enters the voice coil 209, the voice coil 209 can vibrate in the magnet 207 along the axial direction of the speaker, so that the vibration of the voice coil 209 drives the diaphragm 205 to vibrate, and the diaphragm 205 vibrates to compress the air inside the cabinet 1, thereby generating sound waves and air flow, and the speaker will make a sound.

As shown in fig. 7 and 8, the second sound emitting portion 3 and/or the third sound emitting portion 4 includes: a suspension edge 303, a folding ring 301, a diaphragm 302 and a dust cover 304.

The hanging edge 303 is of a circular structure, the outer edge of the hanging edge 303 is connected with the box body 1, and the inner edge of the hanging edge 303 is connected with the folded ring 301; the folding ring 301 is of an arched convex annular structure and is connected with the inner edge of the hanging edge 303; the vibrating diaphragm 302 is in a conical structure, and the opening edge of the cone is connected with the folding ring 301; a dust cover 304 covers the surface of the diaphragm 302, and a round edge of the dust cover 304 is connected to an inner edge of the corrugated rim 301 for preventing dust from entering the interior of the sound-emitting portion.

In the first specific embodiment, as shown in fig. 7 and 8, the second sound-emitting portion 3 includes: corrugated rim 301, diaphragm 302, suspended edge 303 and dust cover 304.

In the second specific embodiment, as shown in fig. 7 and 8, the third sound-emitting portion 4 includes: corrugated rim 301, diaphragm 302, suspended edge 303 and dust cover 304.

In a third specific embodiment, as shown in fig. 7 and 8, the second sound emitting portion 3 and the third sound emitting portion 4 each include: corrugated rim 301, diaphragm 302, suspended edge 303 and dust cover 304.

Thus, when the first sound-emitting portion 2 vibrates to emit sound, the air inside the box 1 is compressed, so as to drive the diaphragms 302 of the second sound-emitting portion 3 and the third sound-emitting portion 4 to vibrate back and forth, so that the second sound-emitting portion 3 and the third sound-emitting portion 4 emit sound.

The kind of diaphragm is also various. For example, the type of the diaphragm may be a cone diaphragm, a plastic diaphragm, a metal diaphragm, a synthetic fiber diaphragm, or the like, and the diaphragm used in the sound-emitting portion shown in fig. 5 is a cone diaphragm.

Like this, because the vibrating diaphragm is the cone vibrating diaphragm, cone weight is light, and energy conversion is efficient, and because inside fibrous interweaving, the energy in the transmission course can be absorbed very fast, so the damping characteristic of cone is also more ideal, the tone quality of improvement audio amplifier that can be fine, brings better sense of hearing experience for the user.

Alternatively, the shape of the sound-emitting portion may be various, and for example, the shape of the sound-emitting portion may be circular, elliptical, rectangular, or racetrack.

Thus, the application range of the sounding part can be enlarged, and the applicability of the sound box is improved. For example, the sound range of the circular horn is narrow, the sound range of the elliptical horn is wide, the elliptical short-axis cone emits high-pitched sound, the elliptical long-axis cone emits low-pitched sound, and therefore the effect that one horn can simultaneously give consideration to both high-pitched sound and low-pitched sound can be achieved.

Alternatively, the second sound emitting portions 3 provided on the front case 101 are symmetrically distributed on the front case 101 with respect to the first sound emitting portions 2 provided on the front case 101. For example, the second sound emitting portion 3 and the first sound emitting portion 2 may be symmetrically distributed about a central axis of the front case 101 in the axial direction, and the second sound emitting portion 3 and the first sound emitting portion 2 may also be symmetrically distributed about a central point of the front case 101.

Like this, through with second sound production portion 3 and first sound production portion 2 symmetric distribution, can make the focus of box 1 on the central point of box 1 to make box 1 more firm when first sound production portion 2 phonation, can not follow first sound production portion 2 vibration.
