Aiming at the problems, the novel design is carried out on the basis of the original low-frequency output loudspeaker.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a low frequency output loudspeaker for TV set to solve the inside electronic component and the space influence of its such as the limited in TV set, portable audio amplifier and Ai smart audio amplifier that provide among the above-mentioned background art, can't replay the problem of better low frequency output.
In order to achieve the above object, the utility model provides a following technical scheme: a low-frequency output loudspeaker for a television comprises a panel, a terminal board, a driving loudspeaker, elastic padding cotton and a rear cover, wherein the driving loudspeaker and the elastic padding cotton are nested in the middle of the panel and the rear cover, and the terminal board is arranged on the rear cover.
Preferably, the panel is directly bonded or attached to a voice coil or a paper cone of a drive horn on the back cover.
Preferably, the elastic pad cotton is nested and installed between the panel and the back cover.
Preferably, the rear cover is provided with a horn installation groove and a terminal board installation groove, respectively.
Preferably, the horn mounting groove and the terminal plate mounting groove are respectively engaged with the driving horn and the terminal plate.
Preferably, a data slot is formed at an edge position of the terminal plate mounting groove.
Compared with the prior art, the beneficial effects of the utility model are that: the television is provided with a low-frequency output loudspeaker,
1. the application of a special bidirectional vibrating diaphragm structure (the panel and the rear cover of the nested device are respectively used as two different vibrating diaphragms of the low-frequency output loudspeaker, and the two-way vibration is realized through the driving loudspeaker in the special bidirectional vibrating diaphragm structure) in a TV set loudspeaker (sound box) and other sound boxes and the low-frequency output response of the loudspeaker (sound box) is effectively improved and solved by introducing the working principle of the special vibrating diaphragm;
2. the technical improvement is directly carried out on the design of the built-in loudspeaker of the TV set, the 'ultra-thin' compression design of the integral TV set in the market is facilitated by introducing 'special bidirectional vibrating diaphragm structure design and working principle', and the low-frequency output sound effect with strong surge can be completely comparable to that of a SOUNDBAR sound box of an externally connected TV set.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a low frequency output loudspeaker for TV set, includes panel 1, terminal board 2, drive loudspeaker 3, elastic pad cotton 4 and back lid 5, its characterized in that: a driving horn 3 and an elastic pad cotton 4 are nested between the panel 1 and the rear cover 5, and a terminal board 2 is arranged on the rear cover 5;
the panel 1 is directly bonded or connected with a voice coil or a drum paper supporting cup of a driving loudspeaker 3 on the rear cover 5;
the elastic pad cotton 4 is nested between the panel 1 and the rear cover 5, the elastic pad cotton 4 can be transversely placed in a 'mesh' shape structure, including but not limited to only one placing structure, the shape of the elastic pad cotton 4 can be complicated and various and irregular, and the elastic pad cotton 4 not only solves the problems of touch and resonance when the panel 1 and the rear cover 5 vibrate bidirectionally 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 bidirectionally is solved;
the rear cover 5 is respectively provided with a horn mounting groove 6 and a terminal board mounting groove 7, one or more horn mounting grooves 6 are arranged, the number is not limited, and the terminal board 2 and the driving horn 3 are conveniently mounted on the rear cover 5 through the terminal board mounting groove 7 and the horn mounting groove 6 respectively; the design concept that the loudspeaker driving loudspeaker 3, the terminal board 2 and the rear cover 5 are integrated into a whole to be used as a special vibrating diaphragm on one surface is also realized;
