Description

Stereo speaker and stereo system

Technical Field

The utility model relates to a speaker especially relates to stereo audio amplifier.

Background

Conventional stereo systems typically require two separate speakers to be combined to form the left and right channels. Therefore, the volume occupied by the sound box is large, and the sound box is inconvenient. If two sets of loudspeaker units are integrated on one box body, very large vibration inertia can occur when the two sets of loudspeaker units are used, so that the sound dyeing is very serious, and the sound quality of the whole sound box is very poor. If two sound channels are designed in one sound box, the design can place the medium and low-pitch loudspeaker and the high-pitch loudspeaker in the same direction, and the loudspeaker faces the front side in consideration of the directivity of high pitch, so that the medium and low-pitch loudspeaker is difficult to achieve mirror image setting, the vibration inertia of low pitch needs to be offset by the weight of the box body, and the weight of the sound box becomes large.

the bass units of the two groups of sound production units are arranged in a mirror image mode to offset vibration inertia; the outer side of each bass unit is provided with the treble unit.

In a preferred embodiment: four treble units are arranged on the outer side of each bass unit; the high pitch unit is arranged on the left side and the right side of the upper side and the lower side of the low pitch unit.

In a preferred embodiment: the refrigerator also comprises an inverter tube, and the open end of the inverter tube is communicated to the surface of the box body and faces to a user.

In a preferred embodiment: the box body is an integrally formed pressure container.

In a preferred embodiment: the magnets of the two bass units are connected with each other through a connecting piece, and when the two bass units have the movement tendency of approaching to each other or moving away from each other, the connecting piece provides limiting force against the relative movement direction for the bass units.

The utility model also provides a stereo system, include: the two sound boxes respectively correspond to the left sound channel and the right sound channel; each sound box comprises a box body; two groups of sound generating units are arranged on the surface of the box body; each group of sound generating units respectively comprises a bass unit and at least one treble unit;

In a preferred embodiment: the two sound boxes are connected in a wireless mode to form a stereo system.

Compared with the prior art, the technical scheme of the utility model possess following beneficial effect:

1. the utility model provides a stereo speaker, two bass unit mirror images on the box set up, just so can make the vibrations inertia that two bass units produced offset each other, can keep the high fidelity of bass under the circumstances that makes the audio amplifier casing lighter.

2. The utility model provides a stereo speaker, each bass unit outside all sets up a treble unit for the audio amplifier all has balanced audio at 180 degrees within ranges, and inverter tube makes the bass effect not receive the influence that the audio amplifier was put towards the place ahead output in addition.

3. The utility model provides a stereo loudspeaker box also can make up three-dimensional system of becoming with two, and two sets of generating unit in each loudspeaker box just so use as left channel or right channel simultaneously, because two sets of symmetrical structure who takes place the sound production unit for each loudspeaker box has the effect of approaching the point sound source when sending single sound channel audio frequency, just so has very good sound field and restores.

4. The utility model provides a stereo sound box, a bass unit's the outside can set up a plurality of high pitch unit, and this makes this audio amplifier have three-dimensional spatial listening effect (all have balanced audio around the upper and lower left and right sides of audio amplifier).

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and the detailed description.

Example 1

Referring to fig. 1 and 2, the present invention provides a stereo speaker, including: a box body 1; two groups of sound production units 2 are arranged on the surface of the box body 1 and correspond to a left sound channel and a right sound channel; each group of sound units 2 respectively comprises a bass unit 21 and a treble unit 22;

the bass units 21 of the two groups of sound generating units 2 are arranged in a mirror image mode to offset vibration inertia mutually; the treble unit 22 is provided outside each bass unit 21.

In the stereo sound box, the two bass units 21 on the box body are arranged in a mirror image mode, so that vibration inertia generated by the two bass units 21 can be counteracted mutually, and high fidelity of bass can be kept under the condition that the sound box shell is light. Therefore, the tank 1 in the present embodiment can be manufactured by a blow molding integral molding process, and the tank 1 has a shape of a pressure vessel, specifically, a sphere. This can improve the deformation resistance of the case 1.

In the embodiment, the device further comprises an inverter tube 3, and the open end of the inverter tube 3 is communicated to the surface of the box body 1 and faces to a user.

In the stereo sound box, the outer side of each bass unit 21 is provided with the treble unit 22, so that the sound box has balanced sound effect within the range of 180 degrees, and the phase inversion pipe is arranged to output towards the front, so that the bass effect is basically not influenced by the placement of the sound box.

In this embodiment, a user may also connect two stereo sound boxes wirelessly to form a stereo sound system, so that two sets of generating units in each sound box are used as a left channel or a right channel at the same time, and because of the symmetric structure of the two sets of generating units 2, each sound box has an effect of a near point sound source when emitting a single channel audio, so that a very good sound field restoration is achieved.

In this embodiment, the magnets of the two bass units 21 are connected to each other by a connecting member, and when the two bass units 21 have a tendency to move toward or away from each other, the connecting member provides a limiting force to the bass units 21 against the relative movement direction. Thus, the vibration inertia of the two bass units 21 can be completely eliminated, and the sound quality of the sound box is further improved.

Example 2

This example differs from example 1 in that: two treble units 22 are arranged on the outer side of each bass unit 21; the treble units 22 are disposed on the left and right sides of the bass unit 21. Thereby the sound box has the listening effect of 360 degrees in the horizontal direction (the sound effect is balanced at the left, the right, the front and the back of the sound box).

Example 3

Referring to fig. 3 and 4, the present embodiment is different from embodiment 1 in that: four treble units 22 are arranged on the outer side of each bass unit 21; the treble units 22 are disposed at upper, lower left and right sides of the bass unit 21. Therefore, the sound box has the listening effect of a three-dimensional space (the sound effect is balanced on the upper part, the lower part, the left part, the right part, the front part and the rear part of the sound box).

The above description is only an exemplary embodiment of the present invention, and the scope of the present invention should not be limited accordingly. The equivalent changes and modifications made according to the patent scope and the content of the specification of the present invention should still fall within the scope covered by the present invention.
