Problems solved by technology

The bass in the cabin is the basic sound, but the phase difference between the front sound wave and the back sound wave of the woofer is 180°, interference will occur at low frequencies, and the low-frequency sensitivity will be lost. The inner cavity is poorly sealed and the volume is too large, which cannot form a real sound cavity, resulting in poor low-frequency sound effect

Abstract

The invention provides a bass loudspeaker for an automobile, which comprises a loudspeaker body, a cone and a sound cavity box, and is characterized in that the loudspeaker body is arranged in the cone; the cone is arranged on a top plate of the sound cavity box; an inner cavity of the sound cavity box is a sound cavity body; the volume of the sound cavity body is larger than that of an inner cavity of the cone; the inner cavity of the cone is communicated with the sound cavity body; the sound cavity box is positioned on the back surface of the loudspeaker body; the sound cavity box is provided with a vent hole communicated with the sound cavity body; and the sound cavity box is further provided with an installation part used for being connected with a car door metal plate. The sound cavity box is arranged below the cone and located on the back face of the loudspeaker body, compared with a cavity in a car door, a sound cavity body of the sound cavity box has better sealing performance, and meanwhile the size of the sound cavity body can be flexibly set according to needs, therefore, the low-frequency sensitivity and the low-frequency sound effect of the bass loudspeaker can be effectively improved by utilizing the sound cavity body.

Description

technical field [0001] The invention belongs to the technical field of car audio systems, and in particular relates to a bass loudspeaker for cars. Background technique [0002] With the development and progress of automobile intelligence, technology and quality, people have higher and higher requirements for the sound quality of car speakers. The speakers usually installed in the car are electric speakers. The signal current of the sound source flows through the magnetic field generated by the voice coil, and interacts with the magnetic field of the magnet to form an electromagnetic force. The diaphragm vibrates under the action of the electromagnetic force to produce sound. The loudspeaker usually includes a woofer and a tweeter, and has a simple structure and a wide range of applications. The woofers are usually mounted between the door sheet metal and have holes in the interior panels to channel the sound into the car. The bass is the basic sound in the cabin, but the ...
