Problems solved by technology

The maze-type transmission line cavity increases the acoustic resistance of the rear cavity, which makes the sound wave attenuation of the rear cavity larger, which is not conducive to the increase of the total sound pressure level, and the frequency response curve is prone to low-frequency harmonic resonance peaks

Embodiment 1

[0035] Such as figure 1 As shown, the loudspeaker provided by this embodiment includes a box body and a plurality of transducer monomers 2, and a plurality of transducer monomers 2 are installed in parallel in the box body. Under the condition of the same total power, each transducer The power consumed by the monomer 2 is relatively small, and at the same time, the total sound pressure level can be effectively increased. For example: when the number of transducer cells 2 connected in parallel is four, under the same total power condition, each transducer cell 2 only consumes 1 / 4 of the power, but the total sound pressure level can be increased 6dB. Moreover, the front sound chambers 4 of multiple transducer monomers 2 are independent of each other and are used to radiate sound waves from the front; at the same time, multiple transducer monomers 2 share a rear sound chamber 3 to increase the effective volume of the box and effectively reduce the The sound resistance of the re...

Embodiment 2

[0046] The technical content of the second embodiment that is the same as the first embodiment will not be described repeatedly. The disclosed content of the first embodiment also belongs to the disclosed content of the second embodiment. The difference between the second embodiment and the first embodiment is that the inverted The phase hole 31 is replaced by a bass unit. The woofer is located in the rear cavity 3 , and the radiating direction of the woofer is towards the bottom of the rear cavity 3 .

[0047] On the premise of keeping the overall appearance and technical means unchanged, change the inverter hole 31 to a bass unit at the bottom, so that the total number of units is five: four transducer units on the front radiation surface 2 Parallel drive is adopted, and the woofer in the rear sound chamber 3 is independently driven by hardware frequency division. Although the requirements for the power amplifier in this embodiment have been improved, the overall bass sense...

Abstract

The invention relates to the technical scheme of display, particularly to a loudspeaker and a television with the same. The loudspeaker comprises a box and a plurality of transducer units which are in parallel connection in the box. Front sound chambers of the transducer units are separated. The transducer units share a same rear sound chamber. The loudspeaker with the high-sound pressure level output is small in power loss, low in acoustic resistance of the rear sound chamber and high in low-frequency lower limit frequency. The loudspeaker can be assembled on the television and used with a rear shell of the television, allowing correction of sound wave phase of the rear sound chamber and front sound wave phase to be facilitated and has the advantages such as pure and sweet sound, wide and rich voice compass, and energy conservation and environment protection.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a loudspeaker and a television provided with the loudspeaker. Background technique [0002] With the development of modern society and the improvement of living standards, the sound quality of TV sets has attracted more and more attention from consumers. How to design the speaker under the condition of limited size, and finally obtain abundant, powerful, beautiful and delicate sound quality effect has become more and more the key point of the competition for the strength of various manufacturers. [0003] In order to improve the sound quality effect, there is a speaker system in the prior art, which includes a cabinet, at least one speaker unit attached to the cabinet, and a plurality of passive radiators attached to the cabinet, each passive radiator includes a vibrator Diaphragm and support system for supporting the diaphragm. The loudspeaker system proposes a multi-unit box...
