Abstract
The utility model relates to a portable ultra-thin speaker, belonging to electroacoustic devices. A front shell and a rear shell form an inner cavity, the rear shell is longitudinally provided with four clapboards, an inner cavity is divided into two symmetrical seal cavities and a central mini-cavity, a power-amplification module is fixedly connected with the inner surface of the back shell through a bolt in the central mini-cavity, a seal frame is arranged around the edges of each seal cavity, an inverted tube is arranged at outer side of each seal cavity, and an outlet end is transited from a circular section to an elliptic section. A vibration diaphragm material can be a composite material surface plate of a honeycomb structure and can be also a macromolecular resin material of the honeycomb structure. The portable ultra-thin speaker has the advantages of good bass effect, small distortion, high electroacoustic conversion efficiency, omnibearing vision and audition feelings of 360 DEG, coordinative appearance structure and artificial and aesthetic performances, portability in volume, high electroacoustic conversion rate and low energy consumption.
Description
Technical field
The utility model belongs to electro-acoustic element, refers in particular to a kind of sound equipment.
Background technology
At present, the portable audio product on the market often has the shape of rule, for example: cuboid, cube etc., give stereotyped, plodding sensation.And speaker portion directly exposes, and just has artistry design to a certain degree at the outward appearance design aspect; Tonequality is bad, and its reproduction performance to bass is poor; The loud speaker that portable audio adopts is awl basin structure, is difficult to realize the structural design of slimming.
Summary of the invention
The utility model provides a kind of portable ultra-thin sound equipment, and common sound equipment shape dullness is thick and heavy to solve, the problem of lower tone.
The technical scheme of the utility model is: the inner surface of procapsid has the screwed hole bearing, and plate diaphragm loud speaker and back casing all are fixedly connected with screwed hole bearing on the procapsid inner surface through screw, and procapsid and back casing form internal cavity; Back casing vertically has four road dividing plates; Internal cavity is divided into closed cavity and the little cavity of central authorities of two symmetries, and power amplifier module is fixedly connected with the back casing inner surface through screw in the little cavity of central authorities, and the edge of closed cavity is provided with the sealing frame; Phase-reversing tube is positioned at the outside of closed cavity; For Z-shaped, the cross section is circular, and the port of export carries out the transition to elliptic cross-section by circular cross-section.Diaphragm materials can be the composite material flat plate of honeycomb, also can be the macromolecule resin material of honeycomb.
The advantage of the utility model is: bass effect is good, distortion is little, electro-acoustic conversion efficiency is high, have the comprehensive audio visual impression of 360 degree, contour structures and artistic aesthetic property is coordinated, the ultra-thin sound equipment of volume low energy consumption portable, that the electroacoustic transfer ratio is high.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
The inner surface of procapsid 1 has the screwed hole bearing, and plate diaphragm loud speaker 3 and back casing 5 all are fixedly connected with screwed hole bearing on procapsid 1 inner surface through screw, and procapsid 1 forms internal cavities with back casing 5; Back casing 5 vertically has four road dividing plates; Internal cavity is divided into closed cavity 8 and the small-sized cavity 7 of central authorities of two symmetries, and power amplifier module 6 is fixedly connected with back casing 5 inner surfaces through screw in the small-sized cavity 7 of central authorities, and the edge of closed cavity 8 is provided with and seals frame 4; Phase-reversing tube 2 is positioned at the outside of closed cavity 8; For Z-shaped, the cross section is circular, and the port of export carries out the transition to elliptic cross-section by circular cross-section.
Diaphragm materials can be the composite material flat plate of honeycomb, also can be the macromolecule resin material of honeycomb.
The working method of the utility model: the output signal of source of sound inserts plug through audio signal and handles through built-in power amplifier module 6; Drive the inner plate diaphragm loud speaker 3 of said portable ultra-thin sound equipment; Produce the mechanical oscillation of expecting at procapsid 1 and the closed box that back casing 5 forms, promote air and sound; Phase-reversing tube 2 produces reversing with the sound wave phase place of said plate diaphragm loud speaker 3 radiation rearward; And the acoustic signals through the reversing of phase-reversing tube outlet output phase; With the sound wave stack of said plate diaphragm loud speaker 3 radiation forwards, can obviously promote the bass effect of sound equipment; Plate diaphragm loud speaker thin thickness, diaphragm materials are honeycomb, have the slimming of being easy to design, no the best is listened to position limit, electroacoustic transfer ratio height.
