Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of audio, in particular to a subwoofer with double speakers. Background Art
[0002] "Subwoofer" is a common term or abbreviation, but strictly speaking, it should be referred to as "subwoofer." This term was first coined, and the localized term "subwoofer" was pioneered by Mai Lan. In terms of audible audio, it consists of subwoofer, bass, low-midrange, midrange, mid-treble, treble, and super-treble, which enhance the rhythm of syllables. Simply put, bass is the basic framework of the sound, midrange is the flesh and blood, and treble reflects the details.
[0003] After searching, the Chinese utility model patent with patent application number CN202120218921.0 discloses a car-mounted subwoofer, which relates to the field of audio technology, including a sound basin, a basin frame with a cavity formed inside, and a T-iron, a magnet, a splint, a bracket, an elastic pad, a voice coil and a spring contained in the cavity. The elastic pad is arranged between the bracket and the splint. The elastic pad, the splint, the magnet and the T-iron form a gap space. The voice coil is connected to the bracket and can vibrate up and down along the gap space. The utility model adds an elastic pad in the matching space between the bracket and the splint, so that the bracket can achieve elastic movement up and down through the spring while further achieving elastic buffering with the splint through the elastic pad, thereby limiting the downward vibration stroke of the voice coil connected to the bracket, avoiding the phenomenon of the voice coil hitting the bottom, and improving the service life of the car-mounted subwoofer; and the elastic pad is made of elastic material, which can effectively reduce the impact on the vibration of the voice coil, thereby ensuring the sound quality of the car-mounted subwoofer.
[0004] For example, the Chinese utility model patent with patent application number CN202223216525.8 discloses a subwoofer speaker including a box body, a cover plate, a top cover, a support column, a speaker and a foot. The box body is provided with a top plate, a cavity and a bottom plate. The top plate is provided with mounting holes and positioning holes, and the cover plate is provided with through holes and fixing holes. A gap is formed between the top cover structure and the speaker, so that the sound quality of the speaker is better and the sound emitted is louder. The speaker is fixed by the top plate and the cover plate, so that the installation of the speaker is stable and will not vibrate or even loosen when playing music. The external wiring can also be wrapped in the groove of the foot to facilitate the storage of the wire, which greatly improves the user experience.
[0005] Although the above-mentioned existing subwoofers can meet the basic heat dissipation requirements, they all use a woofer to play the heavy bass. Due to the low electro-acoustic conversion rate, small speaker vibration area, insufficient sound radiation and poor bass effect of this subwoofer, the bass effect it can create is difficult to meet the auditory requirements of people when watching movies or playing games.
