Description

Shockproof layer for sound box base

Technical Field

The utility model relates to a sound equipment, especially a shockproof layer for audio amplifier base.

Background

The acoustic device is a transducer for converting an electric signal into an acoustic signal, and the quality of the performance of the loudspeaker greatly affects the sound quality. The loudspeaker is the weakest component in the audio equipment, and is the most important component for the audio effect. Loudspeakers are of a wide variety and vary widely in price. The audio frequency electric energy enables the paper cone or the diaphragm to vibrate and generate resonance with surrounding air to make sound through electromagnetic, piezoelectric or electrostatic effects, and the paper cone type, the horn type and the diaphragm type are divided according to sound radiation materials; the paper cone is divided into a circle, an ellipse, double paper cones and an eraser folded ring according to the shape of the paper cone; according to working frequency, the system is divided into bass, middle-pitch and treble, and also divided into special recorder, special television, common and high-fidelity loudspeaker and the like; dividing low impedance and high impedance according to the impedance of the voice coil; according to effect division straight spoke and ambient sound etc. current domestic loudspeaker are placed with the form of audio amplifier, and some audio amplifier is placed on ground, and another part's audio amplifier is placed and is installed on the glass board or the plank of wall body, and when the audio amplifier was placed on the ground, because sound was through the vibration transmission, so must arouse the vibration, and this kind of vibration is all-round indiscriminate vibration, and present loudspeaker lack the shockproof function.

Disclosure of Invention

The utility model discloses a solve the technical problem that above-mentioned exists, provide a shockproof layer for audio amplifier base.

The technical scheme of the utility model is realized like this:

the utility model provides a layer of taking precautions against earthquakes for audio amplifier base, includes the base and sets up the layer of taking precautions against earthquakes on the base, the layer order of taking precautions against earthquakes constitute by first sponge layer, spring layer, second sponge layer and sound absorbing layer, first sponge layer is the high density sponge, and the spring layer comprises the tiling of the spring of a plurality of same models, and the second sponge layer is the low density sponge, and the sound absorbing layer is the abatvoix.

The thickness of the first sponge layer is 3-5mm, and the first sponge layer is used for supporting.

The thickness of the second sponge layer is 4-5mm, and a plurality of sponge bubble cavities are arranged in the second sponge layer, so that shock absorption and sound absorption are effectively realized.

The sound-absorbing board is a wood sound-absorbing board, and the thickness of the sound-absorbing board is 15-18 mm.

The sound-absorbing board is characterized in that a wavy third sponge layer and an adhesive layer are further arranged below the sound-absorbing board, the third sponge layer is formed by overlapping a plurality of layers of 1 mm-thick sponge layers, the overall thickness of the third sponge layer is 4-5mm, and the adhesive layer is an adhesive layer.

The utility model provides a base of present audio amplifier lack the problem of shockproof effect, just the utility model discloses simple structure uses, and simple to operate has very big market spreading value.
