Vehicle-mounted sound box and automobile

Abstract

The invention provides a vehicle-mounted sound box and an automobile. The vehicle-mounted sound box comprises a first cover plate, a Second cover plate, a third cover plate and a sound production monomer; the second cover plate and the first cover plate are enclosed to form a rear cavity; the third cover plate and the first cover plate are enclosed to form a front cavity; the sound production monomer is mounted on the first cover plate and is positioned in the rear cavity; The first cover plate is provided with a sounding port which is opposite to the sounding unit and is communicated with thefront cavity, the side part of the second cover plate is provided with a first side sounding port which is communicated with the rear cavity, the side part of the third cover plate is provided with asecond side sounding port which is communicated with the front cavity, and the first side sounding port and the second side sounding port are arranged in opposite directions. According to the vehicle-mounted sound box provided by the invention, sound can be radiated bidirectionally, sound short circuit can be avoided, one vehicle-mounted sound box can cover sound listening areas at multiple positions, defects caused by inconsistent performance of sound production units in a vehicle can be avoided, the number of the sound production units of the whole vehicle can be reduced, and the cost can be reduced.

Description

【Technical Field】 [0001] The invention relates to the field of vehicle-mounted speakers, in particular to a vehicle-mounted speaker and a car using the vehicle-mounted speaker. 【Background technique】 [0002] Now, with the rapid development of automotive electronics technology, excellent in-car audio-visual entertainment systems have become an indispensable part of providing users with an excellent driving experience. One of the key factors affecting the sound quality of the vehicle is the quality of the bass effect of the vehicle. This difficulty has always existed in the design of the vehicle audio system. [0003] Existing vehicle bass design schemes generally use large-diameter circular moving coil electroacoustic transducers. Due to the certain volume of this type of transducer, the installation is limited, and it can usually only be installed on the door, trunk cover or Inside the trunk. In this traditional car bass design scheme, the vocal unit is far away from the user, a...

Problems solved by technology

[0003] The existing car subwoofer design scheme generally adopts a large-diameter circular dynamic electro-acoustic transducer. Due to the certain volume of this type of transducer, the installation is limited, and usually it can only be installed on the door, trunk lid or trunk interior

In this traditional car bass design scheme, the sound unit is far away from the user, and the bass has more losses in the process of propagating in the air. In order to ensure that each position in the car has a sufficient sound pressure level, a larger The input power is not conducive to energy reduction and emission reduction; in addition, in order to ensure a better sound field uniformity in the car, it is generally necessary to arrange multiple woofers in multiple positions to complement the sound field in the car, resulting in a large number of speakers in the car , and the inconsistency of the installation has brought about defects in the sound quality in the car

[0004] Therefore, it is necessary to provide a car speaker to solve the problem that the existing car speaker requires a large input power, which is not conducive to energy reduction and emission reduction.
