Referring to fig. 1-6, the present invention provides a technical solution: a bidirectional vibrating diaphragm type low-frequency output horn for a television comprises a panel 1, a terminal board 2, a driving horn 3, elastic pad cotton 4 and a rear cover 5, wherein the driving horn 3 and the elastic pad cotton 4 are nested in the middle of the panel 1 and the rear cover 5, and the terminal board 2 is arranged on the rear cover 5.
The driving horn 3 comprises a bracket 301, a terminal 302, a U-shaped iron 303, a main magnet 304, a washer 305, an auxiliary magnet 306, a damper 307, a voice coil 308 and a support cup 309, wherein the U-shaped iron 303, the main magnet 304, the washer 305 and the auxiliary magnet 306 are sequentially installed on the inner side of the bracket 301 from outside to inside, the voice coil 308 is arranged at the outer side edge positions of the main magnet 304, the washer 305 and the auxiliary magnet 306, a vibrating diaphragm support cup 309 is arranged at the top of the voice coil 308, and the voice coil 308 is connected with the bracket 301 through the damper 307.
The voice coil 308 is nested between the U-shaped iron 303 and the washer 305, the voice coil 308 is fixedly connected with the diaphragm support cup 309, and the elastic wave 307 on the outer side of the voice coil 308 is positively cut into a wave-shaped structure.
The panel 1 is directly pasted with a voice coil 308 or a vibrating diaphragm support cup 309 of a driving loudspeaker 3 on the back cover 5; the panel 1 is used as one side of a vibrating diaphragm of the driving loudspeaker 3, so that the radiation vibration area and the low-frequency response of the built-in driving loudspeaker 3 are enhanced and improved;
the elastic pad cotton 4 is nested and arranged between the panel 1 and the rear cover 5, the shape of the elastic pad cotton 4 can be complex, various and irregular, and the nested arrangement of the elastic pad cotton 4 not only solves the problems of touch and resonance when the panel 1 and the rear cover 5 vibrate in two directions through the driving loudspeaker 3, but also plays roles of buffering, vibration reduction and amplitude limiting. Meanwhile, the problem of standing wave reflection when the panel 1 and the rear cover 5 vibrate in two directions is also solved;
the horn installation groove 6 and the terminal board installation groove 7 are respectively matched with the driving horn 3 and the terminal board 2, so that the installation stability of the driving horn 3 and the terminal board 2 through the horn installation groove 6 and the terminal board installation groove 7 is improved, and the hidden troubles of inclination and shaking, unevenness and the like after the installation of the horn installation groove 6 and the terminal board installation groove 7 are avoided;
the data wire casing has been seted up to terminal block mounting groove 7's border position, makes things convenient for terminal block 2 and the data line that corresponds to carry out follow-up fixed connection, and terminal block mounting groove 7 can be located 2 loudspeaker or the central point between a plurality of loudspeaker mounting grooves 6 and puts, also can place other positions of upper and lower, left and right back lid.
The working principle is as follows: referring to fig. 1-6, firstly, the terminal board 2 and the driving horn 3 are respectively installed in the terminal board installation slot 7 and the horn installation slot 6 of the rear cover 5, at this time, the terminal board 2 and the driving horn 3 are respectively embedded and integrated with the rear cover 5 through the terminal board installation slot 7 and the horn installation slot 6 of the rear cover 5, after the terminal board 2 and the driving horn 3 are completely installed in the terminal board installation slot 7 and the horn installation slot 6 of the rear cover 5, one surface of the elastic pad cotton 4 is installed with the rear cover 5 through self-adhesion or other glue-free soft fixing methods, after the elastic pad cotton 4 is completely adhered with the rear cover 5, the panel 1 is directly adhered with the voice coil 308 or the support cup 309 of the driving horn 3 on the rear cover 5, the panel 1 is used as one surface of the vibrating diaphragm of the driving horn 3, so as to enhance and improve the vibration area and low frequency response of the built-in driving horn 3, the limitation that the traditional loudspeaker can only produce sound by the vibration film (drum paper) of the traditional loudspeaker is overturned and changed. At the same time, the other surface of the elastic pad cotton 4 is synchronously arranged with the panel 1 by the self-adhesion of the elastic pad cotton 4 or other glue-free soft fixing modes. Finally, the elastic padding cotton 4 nesting device plays a role in amplitude limiting and vibration reduction between the panel 1 and the rear cover 5, and also provides a medium buffering role for realizing the bidirectional vibrating diaphragm structure and the bidirectional vibrating principle of the low-frequency output loudspeaker. This in turn changes the problem of a conventional horn being supported and limited in its radiation stroke entirely by its horn 307 or the diaphragm itself. In summary, it should be added that: the terminal board 2 and the rear cover 5 are fixedly used for being connected with the frequency division network line output between one or more drive loudspeakers 3, the U-iron 303 of the terminal board 2 and the drive loudspeakers 3 is directly connected with the rear cover 5 to form an integral special vibrating diaphragm on the other side of the drive loudspeakers 3, and finally, the design principle of 'two-way vibrating diaphragm and vibration' formed by nesting the panel 1 and the rear cover 5 is realized by driving one or more drive loudspeakers 3, so that the low-frequency burst force and the vibration radiation area and quality of the drive loudspeakers 3 are enhanced and improved, and the industrial problem that the traditional loudspeakers can only push air to sound by means of self vibrating diaphragms, so that the low-frequency response is deficient is also thoroughly solved. The pursuit of low-frequency tone quality of the TV set loudspeaker and other sound boxes and loudspeakers by consumers is improved and satisfied to a greater extent.
