Description

Combined speaker basin stand

Technical Field

The utility model belongs to the technical field of loudspeaker equipment, especially, relate to a modular loudspeaker basin frame.

Background

The horn is divided into several different musical instruments, one wind instrument, which is thin at the top and thick at the bottom and is made of copper. The other is a modern electro-acoustic element, which functions to convert electrical signals into sound, also called a loudspeaker. The horn can also be used for replacing people who blow and publicize, and is divided into a plurality of different musical instruments, one is a wind musical instrument which is thin at the top and thick at the bottom and is made of copper in most cases, and is commonly called a horn. The horn is also commonly called a wind instrument of a suona horn, the upper part is thin and the lower part is thick, and the opening part at the lowest end is opened to the periphery, so that the sound can be amplified. There are many classification methods, generally speaking, into a hole blowing airy musical instrument, a single spring airy musical instrument, a double spring airy musical instrument and a lip spring airy musical instrument, collectively called woodwind musical instruments, although many musical instruments have used metal, rubber or even synthetic materials as raw materials. In orchestras and military bands, this group of instruments is called the woodwind group, and correspondingly, the lip reed airy instrument is called the copper group (in practice this type of instrument is also indeed made of copper). The term loudspeaker is used to refer to a loudspeaker in an electroacoustic component. The horn of wind instrument is called suona horn, horn and horn, as early as 1877, and ErenstVerner of Siemens, Germany patented moving coil horn according to Fleming's left hand law. In 1898, Oliver Lodge Jazz, UK further invented a cone-basin speaker in accordance with the principles of the microphone of the telephone, much like our familiar modern speaker, the Lodge Jazz is called "grower Phone". However, this invention cannot be applied because the LeeDeForest invented the triode vacuum tube until 1906, and the available amplifier made by the method is many years later, so that the cone-shaped horn is gradually popularized until the 1930 s. Another reason is that a new record, electrically recorded in 1921, appeared which had a better dynamic range (up to 30dB) than the traditional mechanically engraved record, so that one had to try to improve the horn characteristics to fit. In 1923, bell laboratories decided to develop sophisticated music reproduction systems including new players and horns, stereo recording and MC heads, stereo scribing methods, etc., which were invented during this wave motion. The research and development of horn is responsible for the major task, and falls into two engineers, CWRice and EWKellogg. The equipment they used was previously unseen at the time, including a 200 watt vacuum tube expander, many bell labs self-completed recordings, various speakers developed in bell labs over the years such as the rudimentary Lodge cone horn, a compressed air horn with diaphragm flaps to control the compressed air flow, corona discharge horns (today's ion drivers), and electrostatic horns.

Most of the traditional loudspeaker basin frames are not easy to disassemble, and the loudspeaker basin frames are easy to damage in transportation, so that certain economic loss can be brought to users.
