Abstract
The utility model relates to a novel sound field LCD. A tombar thite ultra-magnetostriction material Hi-Fi component is arranged at the inner part in a base or an LCD bracket, and is composed of a drive sound production component and a power amplifier component. Under the premise of not changing the appearance and the volume of the LCD, the LCD produces the sound through the tombar thite ultra-magnetostriction material Hi-Fi component hidden at the inner part in the base or the LCD bracket. The fidelity of the output sound is high, and the frequency range is wide without directionality. The novel sound field LCD realizes large power audio frequency direct output of the LCD without arranging an external sound box additionally.
Description
Affiliated technical field
The utility model relates to the sound equipment LCD, especially relates to a kind of LCD that the rare earth ultra-magnetostriction material acoustics is installed.
Background technology
LCD day by day becomes the monitor market main flow with advantages such as its dainty frivolous, conserve space, the low radiation of low power consuming in recent years, but need extra coupling external voice box during common LCD output audio, bevies such as the body of external voice box, tone frequency channel wire, power lead have occupied desk-top space greatly, have influenced the advantage performance of LCD.
Have now some production of liquid crystal displays producers give LCD built-in audio amplifier, below screen, in both sides, behind or the display base, increase common little audio amplifier.But because the restriction of LCD volume and power consumption, built-in speaker pronunciation unit can only be done very for a short time, and power is low, audio distortions, and audio is bad, has influenced user's use.And built-in common audio amplifier also had influence on the appearance design of LCD, makes LCD seem burdensome too fat to move, changed the actual look of LCD.
Therefore, need a kind of LCD appearance design that both do not influenced fully, the sound technique of the audio of directly realizing ideal again output.
The rare earth ultra-magnetostriction material sound equipment has changed the sound producing pattern of traditional sound equipment fully, is carrying under the action of alternating magnetic field of sound signal, by the flexible strain of rare earth ultra-magnetostriction material length, drives the object sounding of contact with it.Because the flexible strain of rare earth ultra-magnetostriction material is big, the response time is fast, energy density high (rare earth ultra-magnetostriction material of diameter 10mm can produce about 200 kilograms driving force), therefore can be in very little spatial volume, realize the fidelity height, bandwidth, aphalangia to the output of high-power audio.
Summary of the invention
The purpose of this utility model is not change under the prerequisite of LCD appearance design directly realization fidelity height, the output of powerful audio on LCD fully.
Technical solution of the present utility model is in LCD bracket or base inside, to hide built-in rare earth ultra-magnetostriction material audible component is installed.The rare earth ultra-magnetostriction material audible component is formed by driving sounding component and power amplifier components two parts.The driving sounding component comprises: rareearth super magnetostrictive rod, solenoid magnetizing coil, bias field magnet, magnetic conduction casing, stress spring, T type driving head, magnetic conduction casing end cap and resilient rubbber cushion.Power amplifier components comprises miniature power amplifier and power circuit, and power circuit also can use the power circuit of LCD itself.Sound signal is after power amplifier components amplifies, and input drives sounding component, drives sounding component and drives the planar medium sounding that contacts with LCD.The deadweight of LCD affacts and drives on the sounding component, and rare earth ultra-magnetostriction material is exerted pressure, and improves the flexible strain of rare earth ultra-magnetostriction material, guarantees to drive the good driving output of sounding component.
The beneficial effects of the utility model are: under the prerequisite that does not change LCD outward appearance volume, make the LCD sounding by the rare earth ultra-magnetostriction material audible component of Hide All in support or base inside.Output sound fidelity height, bandwidth, aphalangia to, and output power is big.Need not additional configuration outside audio amplifier realizes that the audio frequency of LCD is directly exported, and further promotes the space-saving advantage of LCD.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is for driving the structural representation of sounding component.
Embodiment
The utility model is in LCD (1) support or base inside, hides built-in rare earth ultra-magnetostriction material audible component is installed.The rare earth ultra-magnetostriction material audible component is formed with power amplifier components (3) by driving sounding component (2).The basic structure that drives sounding component (2) comprises: rareearth super magnetostrictive rod (4), solenoid magnetizing coil (5), bias field magnet (6), magnetic conduction casing (7), stress spring (8), T type driving head (9), magnetic conduction casing end cap (10) and resilient rubbber cushion (11).Power amplifier components (3) comprises miniature power amplifier and power circuit.
Go up the evenly ultra-thin insulating tape of parcel at rareearth super magnetostrictive rod (4), place solenoid magnetizing coil (5) inside, be stained with bias field magnet (6) respectively at rareearth super magnetostrictive rod (4) two ends, put into magnetic conduction casing (7), between T type driving head (9) and magnetic conduction casing end cap (10), install stress spring (8) additional, on T type driving head (9) bottom and magnetic conduction casing (7) outer rim end face, paste resilient rubbber cushion (11).The driving sounding component that will assemble is at last inserted LCD (1) support or base inside, allow the rubber blanket (11) of deadweight by magnetic conduction casing (7) outer rim end face or upper surface of LCD (1) affact on the magnetic conduction casing (7), affact on the rareearth super magnetostrictive rod (4) of enclosure interior by stress spring (8), housing end plug (10) of tightening etc. then.Because rare earth ultra-magnetostriction material has " jump effect " under the action of compressive stress, flexible strain meeting significantly increases under action of compressive stress, the oscillation power that causes T type driving head (9) increases, simultaneously LCD suppressed the vibration bounce-back of T type driving head (9) from escheat, guaranteed the good driving output of driving sounding component (2).
The miniature power amplifier of power amplifier components (3) and power circuit can place LCD (1) support or base or enclosure interior, also can be integrated on LCD (1) circuit board.
During work, voice signal after power amplifier components (3) amplifies puts on the solenoid magnetizing coil (5) that drives sounding component (2), rareearth super magnetostrictive rod (4) is under the alternating magnetic fields effect, length generation telescopic variation converts electric energy to the mechanical vibration with audio frequency, the planar medium that promotes contact with it by bias field magnet (6), T type driving head (9) vibrates, and realizes audio frequency output.
Claims (2)
1. a novel sound equipment LCD is characterized in that, installs the rare earth ultra-magnetostriction material audible component additional at LCD bracket or base inside.
2. novel sound equipment LCD according to claim 1 is characterized in that, the rare earth ultra-magnetostriction material audible component is formed by driving sounding component and power amplifier components two parts.
