Abstract
The utility model relates to a sound box for the ship, which at least comprises a loudspeaker and a box body, wherein the box body is composed of an upper box casing and a lower box casing. The lower box casing is transited into a half disc through a half oval-shaped section, the upper box casing is transited into a square-shaped surface through a half circular section, and a fixing rack is positioned on the square-shaped surface. An inverse sound tube is composed of a clapping board and a residual cavity after a half loudspeaker is removed from an ellipse. The sound box for the ship belongs to the special shaped box body, and the disadvantages of the vibration is mainly avoided in the sound box. The special shaped structure can be fully realized only through the plastics, and thereby the sound box also has the advantage of moisture resistance, and the sound box is particularly suitable for the random vibration and moist environment of the ship.
Description
Technical field:
The utility model belongs to the loud speaker group in International Patent Classification (IPC), i.e. H04R, audio amplifier particularly peculiar to vessel.
Background technology:
Audio amplifier is made of loud speaker and casing.Casing adopts wood materials to make square body or rectangular body usually.In order to improve tonequality, to increase volume and also designed counter-sound box or claimed phase-reversing tube,, consistent with the phase place of front sounding with the back side sound phase place of falling the turnback.The timber structure audio amplifier is afraid of humidity inevitably; The easiest machine of square body shakes, and when promptly identical with a certain frequency of a certain frequency of the natural resonance frequency of audio amplifier and loud speaker sounding or extraneous vibration, resonates, thereby has destroyed the normal playback of audio amplifier.Ship is in wet environment, during operation random vibration must be arranged, and therefore the design of audio amplifier peculiar to vessel is difficult especially.
The utility model content:
The purpose of this utility model provides a kind of audio amplifier peculiar to vessel, and it is difficult for generator and shakes.
Realize that the new case of above-mentioned purpose is as follows as disclosing:
A kind of audio amplifier peculiar to vessel comprises loud speaker and casing at least, and casing is synthetic by upper and lower case shell; The nowel shell is transited into disc half by half oval cross section; The top box shell is by hemicycle section transitions squarely face; The diameter of top box shell semicircle is identical with the minor axis diameter of nowel shell ellipse, and suitable with the loud speaker bore; The base length of top box shell side shape face is identical with the diameter of nowel shell semi circular surface.
Press such scheme,, and have only plastic shaping fully to realize, therefore be difficult for generator and shake, and be not afraid of humidity because casing belongs to polymorphic structure.If acoustical cotton is arranged in the casing, then effect is better.
Description of drawings:
Figure is that the axle of the novel embodiment of this reality cuts open figure.
Wherein: 1, binding post 2, fixed mount 3, top box shell 4, face shield 5, high pitch loudspeaker 6, woofer 7, the tube of falling the sound 8, nowel shell.
Embodiment:
A kind of audio amplifier peculiar to vessel comprises loud speaker 5,6 and casing at least, it is characterized in that being synthesized by the upper and lower case shell 3,8 of casing; Nowel shell 8 is transited into disc half by half oval cross section; Top box shell 3 is by hemicycle section transitions squarely face; The diameter of top box shell 3 semicircles is identical with the minor axis diameter of nowel shell 8 ellipses, and suitable with woofer 6 bores; The base length that the top box shell is 3 square is identical with the diameter of nowel shell 8 semi circular surfaces.
Nowel shell 8 has a dividing plate, and this dividing plate and semi-elliptical cross-section are removed the remaining cavity in loud speaker 6 backs half, constitute the tube of falling the sound 7.
Also be furnished with acoustical cotton in the casing.
The top fixed mount 2 that also is connected with of top box shell 3.This example has high pitch loudspeaker 5 and woofer 6 by face shield 4 integrators, and the wiring of loud speaker is drawn from binding post 1.Can make panel in addition or comprise the dividing plate of making one.
Casing belongs to polymorphic structure, have only plastic shaping fully to realize, and plastics is not afraid of humidity.In addition, fixed mount 2 and respective members comprise face shield 4 all through the processing of humidity coating, so the utility model are applicable to vibrations and moist operating mode.
