Abstract
The utility model provides a high -fidelity voice, includes loudspeaker and box, its characterized in that, the box including can be with wherein loudspeaker backup pad of loudspeaker embeddings, enclose into cubical space's box support board together with the loudspeaker backup pad, the box support board is bare back flex, package rubbing board face and fretwork portion, loudspeaker are woofer in the heavy -calibre.
Description
Technical field
The utility model relates to audio amplifier and manufactures field, particularly a kind of Hi-Fi sound-box.
Background technology
At present, the body structure kind of audio amplifier is multiple.Due to the characteristic of bass, the bass in sound is also make the most unmanageable part of audio amplifier.
The simplest audio amplifier is exactly baffle formula audio amplifier.Audio amplifier is our daily being commonly called as.Baffle formula audio amplifier is not case in fact, but one block of plate.Because Loudspeaker diaphragm front and back all can sounding, when vibrating diaphragm moves forward, sounding before loudspeaker, when vibrating diaphragm moves backward, the sounding below of loudspeaker.Though front and back can sounding, the sound life period of front and back is poor, i.e. phase difference.This one in front and one in back, phase place is totally poor 180 degree.When in a certain frequency simultaneously tool dephased two sound time, two sound that there is phase difference can occur " counteracting ", will can't hear sound.Usually we claim this phenomenon for " acoustic short circuit ".In order to overcome the impact that " acoustic short circuit " causes, people devise baffle formula audio amplifier.The sound that baffle formula audio amplifier adopts one block of large baffle to come before and after isolated loudspeaker, makes sound backward pass less than coming above, avoids sound quilt " short circuit " above.But the bass of baffle audio amplifier lower limit of living again depends on baffle size with amount sense, baffle audio amplifier must adopt one block of very large baffle could produce the low frequency meeting audition needs, have impact on the aesthetic property of audio amplifier, is unsuitable for industrial production simultaneously;
Airtight audio amplifier is the equal of a kind of infinite baffle audio amplifier, has airtight casing, can overcome " acoustic short circuit ", but the resonance of whole casing take part in sounding, produces standing wave, makes audio distortions.
Pilot hole audio amplifier is current main flow audio amplifier, and paraphase hole audio amplifier is exactly on airtight sound box, output the hole that goes out bass specially.Because the wavelength of bass is longer, will from pilot hole around to front direction, and medium-high frequency due to wavelength shorter, can be absorbed by casing.In fact, pilot hole audio amplifier is exactly the sound sent backward by Loudspeaker diaphragm, and before phase place is made to, and the sound sent forward with Loudspeaker diaphragm is superimposed, makes the LF-response of loudspeaker better.Pilot hole audio amplifier can overcome the impact of " acoustic short circuit ", can also strengthen acoustic low-pass response.But owing to there is casing in pilot hole audio amplifier, the vibration of casing also certainly leads to standing wave, makes audio distortions; In addition, the sound before the bass leading out from pilot hole and loudspeaker arrives the Time Inconsistency of auditor's ear, can make low-frequency distortion after superimposed.
Utility model content
The audio amplifier of above-mentioned several structure is due to its design reasons, and the sound that audio amplifier sends all can distortion.In order to solve audio distortions problem, the utility model provides a kind of body structure and above-mentioned several all different, can realize the audio amplifier of sound high-fidelity.
Technical scheme is as follows: a kind of Hi-Fi sound-box, comprises loudspeaker and casing, and described casing comprises the loudspeaker supporting bracket that loudspeaker can be embedded wherein, the case supports plate surrounding solid space together with loudspeaker supporting bracket, and described case supports plate is hollowed-out board; Described loudspeaker are bass horn in heavy caliber.
Further, described loudspeaker supporting bracket is slightly larger than loudspeaker.
Further, described loudspeaker quantity is at least two.
The beneficial effects of the utility model are:
1, compare with existing pilot hole audio amplifier, bass part does not rely on the mode of swinging to superposition to strengthen, and does not produce low-frequency distortion.
2, adopt hollowed-out board to support sound horn, the standing wave that sound box resonance produces significantly weakens, and makes sound realize high-fidelity.
3, compare with baffle audio amplifier, aesthetic property is strong.
4, because casing itself does not participate in sounding, only as loudspeaker bracing frame, therefore do not have too much restriction to the structure, shape, material etc. of casing, thus the selectable scope of material is more extensive.
Accompanying drawing explanation
Fig. 1 is the utility model front view, and Fig. 2 is the utility model left view, and Fig. 3 is the utility model vertical view.
Embodiment
A kind of Hi-Fi sound-box, comprise loudspeaker 2 and casing, described casing comprises the loudspeaker supporting bracket 1 that loudspeaker 2 can be embedded wherein, the case supports plate 3 surrounding solid space together with loudspeaker supporting bracket 1, and case supports plate 3 comprises the supporting bracket in upper and lower, left and right, rear five faces.The area of described loudspeaker supporting bracket is unsuitable excessive, slightly larger than loudspeaker, makes it loudspeaker to be embedded wherein.
Described case supports plate 3 is hollowed-out board, comprise plate face 311 and hollow-out parts 312, hollow-out parts 312 comprises multiple hollow hole, whole casing does not surround confined space, but surrounding is the hole of hollow out, the standing wave that during sound horn, casing resonance produces weakens greatly, reduces sound, do not make it produce distortion largely.
Described loudspeaker are bass horn in heavy caliber, and quantity has four.The sound bass part that 4 heavy caliber loudspeaker send, even if part is by " short circuit ", bass part still can satisfy the demands.
Claims (3)
1. a Hi-Fi sound-box, comprise loudspeaker (2) and casing, it is characterized in that, described casing comprises the loudspeaker supporting bracket (1) that loudspeaker (2) can be embedded wherein, the case supports plate (3) surrounding solid space together with loudspeaker supporting bracket (1), described case supports plate (3) is hollowed-out board, comprises plate face (311) and hollow-out parts (312); Described loudspeaker (2) are bass horn in heavy caliber.
2. a kind of Hi-Fi sound-box as claimed in claim 1, is characterized in that, described loudspeaker supporting bracket (1) is slightly larger than loudspeaker.
3. a kind of Hi-Fi sound-box as claimed in claim 1 or 2, is characterized in that, described loudspeaker quantity is at least 2.
