Description

Technical Field

[0001] The utility model relates to the technical field of audio, in particular to a high and low frequency separation type sound box. Background Art

[0002] Chinese Patent Publication (Announcement) No.: CN206743542U, Patent Title: High-bass combination speaker, which discloses "a high-bass combination speaker: including a tweeter, a woofer and a mounting ring; the mounting ring includes an outer ring, a bracket and an inner ring, the inner ring is fixedly arranged in the outer ring by the bracket, the tweeter is sleeved in the inner ring, and the sound outlet of the tweeter and the sound outlet of the woofer are located on the same side". This technical solution solves the technical problem that "most of the headphones or speakers on the market use a single speaker as the sound source, and then emit sound through the sound cavity and the sound guide hole. The speaker of such headphones or speakers is single, resulting in a single sound effect and poor sound effect".

[0003] However, the tweeters and woofers are placed at almost the same height. Since the human ear has different perceptions of sound, the tweeter, which is responsible for playing high-frequency signals, should be placed as close to the human ear as possible. The woofer should be close to the ground so that the bass can spread farther. Therefore, the tweeter and woofer should be placed in a high-low order to enhance the sense of layering and sound field, which can further improve the quality of the output sound.

[0004] In addition, China Patent Publication (Announcement) No.: CN206042261U, Patent Title: A Shock-absorbing Multimedia Subwoofer, which discloses "A shock-absorbing multimedia subwoofer, comprising a body and a shock-absorbing fixing seat, the body is mounted on the shock-absorbing fixing seat, the body comprises a shell, function buttons, a receiver, a control chip, a wireless device, a power amplifier, a subwoofer, an air duct and a circuit board, the function buttons comprise a power button, a call button and a volume adjustment button, the call button, the receiver, the wireless device and the subwoofer are all connected to the control chip, the subwoofer is connected to the power amplifier, the shock-absorbing fixing seat comprises a groove, a connecting portion, a lining plate, a first plate, a spring, a second plate and a bottom plate, the groove is connected to the lining plate through a connecting portion, the first plate is mounted on the lower surface of the lining plate, the second plate is mounted on the upper surface of the bottom plate, the spring is mounted between the first plate and the second plate, one end of the spring is fixedly connected to the first plate, the other end of the spring is fixedly connected to the second plate, and a shock absorber is mounted on the bottom plate". The shock-absorbing multimedia subwoofer is provided with a shock-absorbing fixing seat to effectively reduce vibration.

[0005] However, in actual use, this solution mainly uses spring shock absorption, so that the vibration of the subwoofer during use causes the spring to shake under force, thereby causing the subwoofer device to shake. When the vibration is strong, it is easy to cause the device to tip over. In addition, through spring shock absorption, if the device is not fixed during vibration, the vibration can easily cause the device to move, affecting user use. Summary of the invention
