Abstract
The utility model discloses a ceramic sound box, belonging to sound boxes, which comprises a loudspeaker, a frequency divider, a piece of sound-absorbent cotton and an inverted pipe. The housing is made of ceramic material, the front surface and the bottom surface whereof are flat, the left surface, the right surface, the back surface and the top surface whereof are arc shapes with different arc degrees, the inner wall of the housing is a convex-concave rough surface, so a miniature mute ventricular is produced in the housing, which is useful for absorption and consumption of the harmonic resonance in the housing, and the fidelity of the sound is improved further. The inverted pipe with a long strip shape is arranged at two sides of the sound box to ensure the timbre to be permeating and natural, and the sound image to be arranged exactly. The utility model has the advantages of reducing the standing wave, good acoustics, and beautiful and generous appearance.
Description
Technical field
The utility model relates to a kind of ceramic loudspeaker box, belongs to a kind of audio amplifier.
Background technology
The casing of existing audio amplifier all adopts wooden or plastic production, and being shaped as rectangular box or sidewall is polyhedral sound box, and the rigidity of casing is lower, and anti-deformation behavior is poor.Because casing proportion is little, light weight is poor to the vibration suppression function of casing.When loud speaker in big dynamically work down, casing easily produces bigger strain, and the displacement of the diaphragm of loudspeaker and acceleration are obviously reduced, can not promptly change the transient response weak effect with music signal.Announced that a kind of patent No. was the utility model patent of 94249056-8 in 1996---ceramic sound equipment.Sound box is by ceramic making, and the overall structure of audio amplifier is be the rotary body of axle vertically, and the interior sound chamber of sound equipment face is for seamlessly transitting curved surface.The leading note mouth is located at the antetheca or the rear wall of audio amplifier bottom.It is good that it has the elastoresistance deformability, and the transient response effect of audio amplifier greatly improves, and makes audio amplifier possess higher fidelity.But, owing to sound chamber in the audio amplifier for seamlessly transitting curved surface, still not ideal enough to the absorption of resonance wave and clutter, for strengthening stereo and keep the effect of original musical sound aspect to still have weak point, cost of manufacture is higher.
Summary of the invention
The purpose of this utility model be to overcome the weak point in the background technology and provide a kind of and can reduce standing wave, tonequality is good, fidelity is effective, penetrating natural, the acoustic image accurate positioning of tone color, indeformable ceramic loudspeaker box elegant in appearance.
The purpose of this utility model is achieved in that a kind of ceramic loudspeaker box, it comprises casing that ceramic material is made and loud speaker, frequency divider, acoustical cotton, phase-reversing tube etc., the front of casing and bottom surface are the plane, the left side, the right side, back and top are the circular arc of different radians, the inwall of audio amplifier is concavo-convex pitted skin, phase-reversing tube becomes strip, be located at the audio amplifier both sides, it is semicircle that phase-reversing tube also can become, be located at the both sides of audio amplifier baffle, in order to improve quiet effect, the concavo-convex pitted skin of its audio amplifier inwall is made irregular sawtooth pattern or granular pattern.Technique effect of the present utility model is:
1. be the circular arc composition of different radians owing to the left side, the right side, back and the top of casing, thereby make the inner generation that reduces standing wave, tonequality is good.
The inwall of 2 ceramic casings is concavo-convex pitted skin.Be irregular serrated face or particle pitted skin, acoustical cotton is housed on the face.Produce a small silent chamber in the casing thereby make, help the absorption and the consumption of the resonance wave in the casing, it is effective to send the former accent fidelity of primary sound;
3. phase-reversing tube is that two long strip types or two are semi-circular, is located at the both sides or the audio amplifier baffle both sides of audio amplifier, thereby makes the penetrating nature of tone color, acoustic image accurate positioning;
4. the casing material is a pottery, but integrated molding, good airproof performance, the intensity height, density is big, and rigidity is strong, and outward appearance can arbitrarily make, and has excellent mechanical property.
The explanation of accompanying drawing drawing:
Accompanying drawing 2 is a semicircular ceramic loudspeaker box structural representation (broken section) for phase-reversing tube
The concavo-convex pitted skin 6 of body inwall, acoustical cotton 7.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and example:
As shown in Figure 1: casing 1 is the ceramic material one-shot forming, its front and bottom surface are the plane, the left side, the right side, back and top are the circular arc type of different radians, phase-reversing tube 3 is strip or semicircle, the phase guide tube 3 of strip is located at the both sides of casing 1, as makes 3 both sides that are located at audio amplifier baffle 2 of semicircular phase-reversing tube.Loud speaker 4 is located at the middle and upper part of baffle 2, and frequency divider 5 is located at bottom in the casing 1; As shown in Figure 2, casing 1 inwall is concavo-convex pitted skin 6, and this concavo-convex pitted skin 6 is irregular sawtooth pattern or granular pattern, on concavo-convex pitted skin 6 acoustical cotton 7 is housed also.
Claims (3)
1 one kinds of ceramic loudspeaker boxes comprise casing that ceramic material is made and loud speaker, frequency divider, acoustical cotton, phase-reversing tube, and the front of casing and bottom surface are the plane, and the left side, the right side, back and top are the circular arc of different radians, it is characterized in that:
A. the sound box inwall is concavo-convex pitted skin;
B. phase-reversing tube is elongated in the audio amplifier both sides.
But 2 ceramic loudspeaker boxes according to claim 1 is characterized in that also semicircular in shape of phase-reversing tube, are located at the both sides of audio amplifier baffle.
3 ceramic loudspeaker boxes according to claim 1 is characterized in that the concavo-convex pitted skin of cabinet wall is irregular sawtooth pattern or particle shape.
