Abstract
The invention discloses a sound box. The sound box comprises a box body and a loudspeaker arranged on the box body. The box body comprises an outer box and an inner box arranged in the outer box, the inner box is made of wood material, and the outer box is made of plastic. Through the inner box made of the wood material and the outer box made of the plastic, the tone quality of the sound box can be ensured, and the appearance of the sound box can be manufactured into the required shape.
Description
Technical field
The present invention relates to a kind of stereo set, relate in particular to a kind of audio amplifier.
Background technology
Existing audio amplifier adopts timber to make sound box usually, but because timber lacks plasticity, therefore is difficult to produce various complicated shapes, causes the sound box shape single.And wooden casing is formed by the polylith wood board splicing usually, causes casing gas leakage easily.And adopt the stronger plastics of plasticity to make sound box, then the tonequality of audio amplifier is relatively poor.
Summary of the invention
In view of this, be necessary to provide the audio amplifier that a kind of tonequality is good and face shaping is made easily.
A kind of audio amplifier, it comprises casing and the loud speaker of being located on the described casing.Described casing comprises outer container and the interior case of being located in the described outer container, and described interior case is made by wood materials, and described outer container is made of plastics.
Above-mentioned audio amplifier by wood materials is set interior case and the outer container of plastics, both can guarantee the tonequality of audio amplifier, be convenient to again the outward appearance of audio amplifier is made into required form.
Description of drawings
The stereogram of the audio amplifier that Fig. 1 provides for a better embodiment.
Fig. 2 is the cross section view of audio amplifier among Fig. 1.
Fig. 3 is the cross section view of the audio amplifier that provides of another better embodiment.
Embodiment
Below in conjunction with accompanying drawing, be described in further detail.
Figure 1 shows that the schematic diagram of a better embodiment audio amplifier 100.This audio amplifier 100 comprises the casing 10 of hollow and is located at loud speaker 20 and phase-reversing tube 30 on the casing 10.
See also Fig. 2, casing 10 comprises interior case 12 and is sheathed on interior case 12 outer container 14 outward.The cavity 16 that has hollow in the interior case 12.Interior case 12 is made by wood materials, and 14 of outer containers are made of plastics.Described wood materials can be natural wood, also can be Homogenholz.Interior case 12 fits tightly with outer container 14.The opening 18,19 of case 12 and outer container 14 in casing 10 is provided with and runs through.In the present embodiment, outer container 14 is to be made of one piece, thereby has guaranteed the air-tightness of outer container 14, causes noise to avoid casing 10 gas leakage.Be appreciated that between outer container 14 and the interior case 12 and also can keep at a certain distance away.
Phase-reversing tube 30 is for being fixed in the hollow cylinder body on the casing 10, and the one end is outside opening 19 is exposed to casing 10, and the rear end then is positioned at cavity 16.It is used for phase-reversing tube 30 producing the consistent sound of phase place of the sound that sends with loud speaker 20 according to the air vibration in the cavity 16 outside casing 10, and this sound is sent outside casing 10, with the audio of enhancing audio amplifier 100.
The interior case 12 by wood materials is set and the outer container 14 of plastics both can guarantee the tonequality of audio amplifier 100, were convenient to again the outward appearance of audio amplifier 100 is made into required form.
In addition, when using audio amplifier 100, loud speaker 20 is sounding to casing 10 outside, and drives the air vibration in the cavity 16, and 10 of casings with the air vibrations in the cavity 16 also sounding of vibration take place.The sound that casing 10 is sent is produced by interior case 12 and outer container 14 secondary vibrations, and its tonequality is better.
See also Fig. 3, in other embodiments, also can the interval preset distance between at least a portion inner surface of outer container 14a and the outer surfaces of interior case 12a.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection range that all should belong to claim of the present invention with distortion.
