Benefits of technology

The present invention provides a speaker unit that can install an external amplifier on the side of a subwoofer without changing the structure of an existing audio system. This arrangement helps to save space and reduce weight in vehicles, lowers costs, and is easily applicable to small-sized vehicles. The simplified structure also helps to save manufacturing time. Additionally, the cooling effect is improved by directly cooling the amplifier circuit using the air flow caused by the vibration of the vibration plate.

Problems solved by technology

The size of the external amplifier for driving the subwoofer unit takes up a considerable amount of space, it is difficult to secure a space for installation, and it is necessary to change many parts, such as the body and the chair.
In addition, the external amplifier requires a large heat sink and the like, and even if the amount of increase of about 1 kg is applied, the fuel consumption is greatly influenced.
In addition, due to the simplification of the structure of the speaker unit, there is a time saving effect on manufacturing.

Abstract

A speaker unit for a vehicle includes a subwoofer unit for outputting sound in a base sound region, an amplifier (AMP) circuit unit mounted on a side of the subwoofer unit for amplifying an acoustic current signal and supplying the amplified acoustic current signal to the subwoofer unit, and an amplifier protection cover unit coupled to the subwoofer unit at one side of the subwoofer unit and configured to cover the amplifier circuit unit.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to and the benefit of Chinese Patent Application No. 201811494447.3 filed in the Chinese Property Office on Dec. 7, 2018, the entire contents of which are incorporated herein by reference.BACKGROUND(a) Field[0002]The present disclosure relates to a speaker unit for a vehicle, more particularly, to a speaker unit for a vehicle which is provided with a subwoofer with an amplifier circuit.(b) Description of the Related Art[0003]A speaker is a device for outputting an audio signal in a voice (acoustic) form so that a listener can listen to the input audio signal. A speaker may include a general speaker for outputting a voice in a treble range and a woofer speaker for outputting a voice in a bass range. A device for amplifying and supplying a voice current signal to a speaker device is referred to as an amplifier (AMP), and a voltage or power of the signal applied to the input side is amplified and output with a...
