Description

Speaker device for easy vibration absorption

The present invention is a speaker that emits a sound signal transmitted to the outside for the user to listen to, the vibration absorbing plate is installed between the speaker case coupled to the high information of the cabinet to absorb the vibration generated from the speaker case cabinet The present invention relates to a speaker device capable of easily absorbing vibrations to prevent micro phonic phenomenon due to vibrations.

In more detail, the vibration absorbing plate is formed in the rear of the speaker grill formed in the television cabinet is integrally installed with high information, and the elastic support piece having a guide groove inserted into the high information on one side of the high information. It is installed, the through groove is formed in the center of the vibration absorbing plate is formed a plurality of screw grooves on the periphery, the speaker case is coupled to the speaker coupled to one side of the vibration absorbing plate.

Accordingly, the speaker case coupled to the rear of the speaker grill is coupled to the high information by the vibration absorbing plate interposed therebetween, so that the vibration generated in the speaker case is absorbed by the elastic support pieces of the vibration absorbing plate to be transmitted to the cabinet. It prevents deformation of the cabinet due to vibration in advance, and installs and absorbs vibration easily by installing vibration absorbing plate having a plurality of elastic support pieces, and it is easily manufactured and installed. Monitor by vibration transmitted to the cabinet It is to prevent microphonic phenomenon and abnormal sound of speaker.

In general known televisions, the CRT operates an audio receiving circuit section consisting of a voice receiving circuit and a speaker for detecting a signal relating to sound in the airwaves of the television, an image receiving circuit section detecting a video signal, and a color signal input to the video receiving circuit. It consists of a color signal reproducing circuit which makes a primary color signal and a synchronous deflection circuit part which assembles an image on the fluorescent surface of a CRT by extracting a synchronous signal from a video signal and operating a horizontal and vertical deflection circuit based on this. To be combined.

In the conventional television speaker device having such a configuration, the speaker 54 is provided inside the cabinet 53 of the television 52 in which the grill 51 is formed forward as shown in Figs. ) Is integrated into the speaker case 55 is installed, one side of the speaker case 55, the screw groove 56 is formed integrally, the screw in the high information 59 is formed inside the cabinet 53 It consists of a configuration combined as 58.

In the above-described television speaker apparatus, the speaker case 55 in which the speaker 54 is integrally fixed to the inside of the cabinet 53 of the television 52 in which the grill 51 is formed on both sides of the front is provided in the cabinet 53. The vibration sound of the speaker 54 is firmly coupled to the high information of the through the screw 58, and when the speaker sound is emitted from the speaker 54 fixed to the inside of the speaker case 55, the grille of the cabinet 53 It is emitted through 51 to allow the user to listen to the sound.

However, in the woofer as described above, when the speaker 54 emits sound, the speaker case 55 coupled to the inner surface of the grill 51 of the cabinet 53 vibrates as well as the speaker case 55 integrally. Vibration up to the cabinet 53 to be coupled to generate an abnormal sound by mutual resonance, thereby degrading the sound quality of the television 52, the inconvenience of not being able to hear the sound of a high output by the vibration and only a sound within a certain frequency range In addition, the vibration is transmitted to the CRT coupled to the cabinet 53 by vibration, and there are many problems such as a microphonic phenomenon that causes screen distortion.

The present invention has been made in order to improve the various conventional problems as described above, its purpose is to absorb the vibration generated in the speaker case to be coupled by a vibration absorbing plate interposed a speaker case coupled to the rear of the speaker grill By absorbing by the elastic support of the plate prevents deformation of the cabinet due to the vibration transmitted to the cabinet in advance, and by installing a vibration absorbing plate having a plurality of elastic support pieces in a simple configuration that easily absorbs vibration And it is easy to install, to provide a speaker device that is easy to absorb vibration to prevent the microphonic phenomenon of the screen due to the vibration transmitted to the cabinet and the occurrence of abnormal sound of the speaker.

Technical configuration of the present invention for achieving the above object, the high information is integrally installed to the rear of the speaker grill formed in the television cabinet, a plurality of elastic support pieces having a guide groove on one side of the high information is formed The vibration absorbing plate is installed, the through groove is formed in the center of the vibration absorbing plate is formed a plurality of screw grooves on the periphery, the speaker case coupled to the speaker on one side of the vibration absorbing plate is composed of a screw coupling By providing a speaker device that can easily absorb vibration.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a schematic cross-sectional view showing a coupled state of the vibration absorbing easy speaker device according to the present invention, Figure 3 is a schematic view showing a vibration absorbing plate for the support of the speaker device according to the present invention, the subject innovation is a television cabinet ( A plurality of high information 4 is provided to the rear of the speaker grill 2 integrally formed on one side of 1).

In addition, the outer periphery of the plurality of elastic support pieces (7) inserted into the high information (4) has a fixing groove (6) at one end to be coupled to each other by the coupling means (3) that is heat-sealed, so that obesity and valleys are connected A vibration absorbing plate 8 protruding to one side is installed, and a through groove 9 is formed at the center of the vibration absorbing plate 8, and a plurality of screw grooves 10 are formed at the periphery thereof.

Subsequently, a speaker case 12 having a speaker 11 coupled to one side of the vibration absorbing plate 8 forward is made of a screw 5 coupled to the screw groove 10 of the vibration absorbing plate 8. Lose.
