Description

Speaker suspension {SUSPENTION OF SPEAKER}

The present invention relates to a suspension of a speaker, and more particularly, to a suspension of a speaker that supports a vibration state while providing a vibration plate attached to an upper portion and a voice coil attached to a lower portion, thereby providing a power supply line function of the voice coil. When fixing with the parts (case, diaphragm, coil) to which the suspension is attached or attached, increase the fixing force of the corresponding fixed portions, and prevent the stress from being concentrated on both ends of the vibration supporting, external terminal The polarization of +/- polarity to be connected with the clear to prevent the misassembly or misuse of the polarity, in particular, in the case of a rectangular speaker relates to a suspension of the speaker to prevent both ends of the long axis direction of the diaphragm during the vibration.

In general, a speaker refers to an acoustic device that generates sound waves by converting an electrical signal into vibration of a diaphragm to generate a small wave in the air. That is, the speaker is a converter that converts electrical energy into acoustic energy, and is largely composed of vibration, support, and magnetic field components.

Such speakers may be classified into various types according to the position of the diaphragm, which is a vibration system component, the shape of the diaphragm, and the principle and method of converting an electrical signal into sound waves. In particular, a speaker used in a display device such as a TV is a radiant speaker in which a diaphragm is placed directly in the air. When a voice signal current flows through a coil located in a magnetic field formed by a permanent magnet, mechanical force is applied to the coil according to the strength of the current. It is common to use principles that work and cause exercise.

Taking the prior art of such a speaker, for example, the Republic of Korea Patent No. 419915, the patent is a broadband reproduction according to the expansion of the large output sound and low-rate bass by a large input electric signal while maintaining a very small ultra-slim framework It is possible to provide a secondary suspension formed of a material having excellent restoring force in order to prevent disconnection between the voice coil and the electrode terminal.

The speaker disclosed in Korean Patent No. 419915 is a micro speaker having a diaphragm in which a yoke, a permanent magnet, a plate and a primary suspension (damper) are integrated, a voice coil, a frame and a protector, And a diaphragm disposed between the plate and the diaphragm, the diaphragm being attached to the secondary suspension such that the voice coil is positioned below the secondary suspension, And an edge (outer peripheral portion) of the secondary suspension is fixed to the frame.

On the other hand, in recent years, due to the development of semiconductor technology, a large display device is widely used. In order to realize a beautiful and concise design of the large display device, in particular, a flat panel display, a speaker must be miniaturized and slimmed.

As described above, when the speaker is miniaturized, the vibration system, the magnetic system, and the support system components constituting the speaker must also be miniaturized. However, if the speaker is miniaturized, the performance is deteriorated due to the reduction of the acoustic radiation efficiency due to the reduction of the effective vibration area, the reduction of the magnetic flux density due to the reduction of the magnetic circuit, the limitation of the vibration width due to the thickness restriction, It is required to realize equivalent performance or more.

In particular, in flat panel display devices, the speaker is mainly limited in width and thickness, and its length is relatively small. Therefore, a speaker of a type that does not reduce the effective vibration area of the speaker by increasing in the longitudinal direction while reducing the width and thickness of the speaker is mainly used. That is, a rectangular speaker having a large ratio of the long diameter (long axis) to the short diameter (short axis) is applied without reducing the effective vibration area.

Examples of the rectangular speaker include Korean Patent Registration No. 10-1100122 (name: speaker; filed on Nov. 10, 2009), and the contents thereof include one or more magnets forming a magnetic field; One or more voice coils that form a magnetic field by an externally supplied current and move by interaction with a magnetic field formed in the one or more magnets; A diaphragm vibrating by the movement of the one or more voice coils to generate sound; And at least one vibration auxiliary member attached to the diaphragm to allow the vibration of the at least one magnet and the at least one voice coil to be evenly transmitted to the entire diaphragm. The vibration aid member is a speaker having a surface of a predetermined width extending downward from the diaphragm, the one or more voice coil is attached to the surface.

At this time, the vibration auxiliary member is provided with a suspension formed in the form of a leaf spring, the suspension is fixed to the outer peripheral surface and the third vibration plate (part that outputs the sound by the actual vibration generated) fixed to the upper surface of the frame The inner peripheral surface and the outer peripheral surface and the inner peripheral surface is made of a vibrating arm for supporting a vibration state by connecting in the form of a flat line.

However, the suspension of the vibration assisting member as described above is fixed to the frame and the third vibrating plate by the outer peripheral surface and the inner peripheral surface, respectively, through adhesion, in this case, there is a problem that the fixed state is broken by frequent vibration and detached. .

In addition, stress is concentrated when both ends of the vibration arm are vibrated, and thus, both ends of the vibration arm connected to each of the outer peripheral surface and the inner peripheral surface may be torn or deformed due to frequent vibration.

In addition, since the vibration assisting member is made of a long axis, the two ends of the vibration assisting member are not vibrated constantly while twisting both ends of the vibration assisting member, which causes distortion in the sound output.

In addition, the rectangular speaker adopts a diaphragm and suspension with a significantly long axis, and the inner ellipse is physically and electrically connected to the outer ellipse by four braking parts, and the diaphragm is thin because the suspension is long in the long axis. There is a problem that the vibration of the diaphragm is uneven according to the rigidity performance of the suspension attached to the upper portion.

In other words, the inner ellipse of the suspension oscillates due to vibration by the long length in the long axis direction of the suspension. Therefore, there is a need to reinforce the rigidity of the inner ellipse to which the voice coil and the diaphragm are attached.

The present invention was created to solve the problems of the prior art as described above, the vibration plate is attached to the upper portion and the voice coil is attached to the bottom, to provide a power supply line function of the voice coil to the suspension of the speaker supporting the vibration state The present invention relates to a method of increasing the holding force of a correspondingly fixed portion when fixing the parts (case, diaphragm, coil) to which the suspension is attached or attached, and to prevent concentration of stress on both ends of the vibration supporting portion. In addition, the polarity of +/- polarity connected to the external terminal is clearly defined to prevent misassembly or misuse of the polarity. In particular, in the case of a rectangular speaker, a suspension of the speaker which prevents both ends of the diaphragm from twisting in the longitudinal direction during vibration is provided. The purpose is to
