Abstract
The utility model provides an air coupling type audio reducing sound box, which comprises a casing, a full-frequency loudspeaker and a duct, and is characterized in that a spherical cavity is arranged in the casing. The cavity is opened with a window for the insertion and assembling of the full-frequency loudspeaker, and also a hole for insertion and assembling of the duct. The wall of the spherical cavity is provided with a sound absorption layer. The air coupling type audio reducing sound box makes use of the principle that the inner spherical cavity has the function of focusing flow segmentation, the ultra-low resonance point and excellent acoustic characteristic is formed in the sound box and the air is activated by an air flow beam of the low turbulence, high speed and high density transformed from axial vibration of a basin body of the loudspeaker, which enhances the overall sound strength. As the vibration body has small vibration quality, the utility model has small distortion and achieves the natural sound natural effect of the high fidelity.
Description
Technical field
The utility model relates to audio amplifier, especially a kind of Air Coupling formula audio frequency reduction audio amplifier.
Technical background
Existing audio amplifier is made up of the casing of rectangle and loud speaker and the frequency divider that is arranged in the casing usually, the audio amplifier of this structure only vibrates with the preceding pelvic surface of sacrum of loud speaker, loud speaker back of the body pelvic surface of sacrum is set in the casing of internally compressed, its efficient is low, mistake is big more, can not reappear audio frequency, and the variation dyeing phenomenon that the case sound standing wave is strong will have a strong impact on the reduction effect of audio frequency.When audio amplifier can be reduced into the audio signal that receives in the outside process of playing of sound,, send a kind of " case sound " that is unfavorable for sound-reducing because audio amplifier when preventing the audio frequency short circuit, can produce bigger covibration.Therefore, the audio amplifier of existing structure all can't reappear the actual field acoustics truly.In addition, the audio amplifier of this structure is at playback time, and audio frequency is subjected to spatial limitation in the casing, can produce compression phenomena, causes speed slow, and phase place is inaccurate, shows as and can not reappear low frequency and extremely low frequency.For remedying the deficiency that existing audio amplifier exists, improve the reduction effect of audio frequency, general at present low alt audio amplifier all need set special-purpose subwoofer audio amplifier and special-purpose amplifier.This can increase the acquisition expenses of sound system undoubtedly.
Summary of the invention
The purpose of this utility model is the deficiency that exists at above-mentioned audio amplifier, and a kind of Air Coupling formula audio frequency reduction audio amplifier that the bass facility can be realized the audio frequency reduction effect that need not be equipped with is provided.
The utility model Air Coupling formula audio frequency reduction audio amplifier, comprise: housing, full frequency speaker and conduit, it is characterized in that: be provided with a cavity spherical in shape in the described housing, cavity offers for full frequency speaker and plants into the window of installation, also be provided with for conduit and insert the hole of installing, internal chamber wall spherical in shape is provided with sound absorbing layer.
Described housing can be made with materials such as timber, plastics, building stones or cement.
The design principle of the utility model Air Coupling formula audio frequency reduction audio amplifier is: the spherical cavity mask has focused gas flow cutting principle in utilizing, make and form ultralow resonance point and good acoustic characteristic in the audio amplifier, with the axial vibration of speaker basket convert low turbulent flow to, high-speed, highdensity air flow stream activates air, strengthen its volume on the whole, because the vibrating body oscillating mass is little, institute is little through the distortion factor, thereby reaches the sound nature reduction effect of high-fidelity.
The utility model Air Coupling formula audio frequency reduction audio amplifier design science, simple in structure, need not be provided with under the situation of woofer, make the reduction of sound reach the natural effect of high-fidelity, to satisfy the appreciation requirement of people to original music.It has not only simplified stereo set greatly, and has reduced use cost.
The concrete structure of the utility model Air Coupling formula audio frequency reduction audio amplifier by the following drawings and
Embodiment provides in detail.
Description of drawings
Fig. 1 is the structural representation of Air Coupling formula audio frequency reduction audio amplifier.
Fig. 2 is another structural representation of Air Coupling formula audio frequency reduction audio amplifier.
Embodiment
Embodiment 1: can be clear that from Fig. 1 Air Coupling formula audio frequency reduction audio amplifier is made up of inner chamber 1 housing 2, full frequency speaker 3 and conduit 4 spherical in shape.Housing 2 is provided with base 10, and housing 2 end faces are offered for full frequency speaker 3 and inserted the window of installing 5, and ball shape inner chamber 1 also is provided with one and inserts the through hole of installing 6 for conduit 4, and the chamber wall of inner chamber 1 is to have uneven 7 of sound-absorbing effect.The afterbody of full frequency speaker 3 inserts the inner chamber 1 of housing 2, and the window of the frame 8 of full frequency speaker 3 and housing 2 end faces 5 is corresponding and be connected and fixed, and conduit 4 is plugged in the through hole 6 of ball shape inner chamber 1.Guard 9 is decorated in the end face configuration of the full frequency speaker 3 of housing 2.
Embodiment 2: the basic structure that can be clear that Air Coupling formula audio frequency reduction audio amplifier from Fig. 2 is identical with embodiment 1, and difference is: ball shape inner chamber 1 wall is provided with the fibrage 11 with sound absorption function.
Claims (3)
1, a kind of Air Coupling formula audio frequency reduction audio amplifier, comprise: housing, full frequency speaker and conduit, it is characterized in that: be provided with a cavity spherical in shape in the described housing, cavity offers for full frequency speaker and plants into the window of installation, also be provided with for conduit and insert the hole of installing, internal chamber wall spherical in shape is provided with sound absorbing layer.
2, Air Coupling formula audio frequency reduction audio amplifier according to claim 1, it is characterized in that: ball shape inner chamber (1) wall is uneven (7).
