Problems solved by technology

However, since the standing electric diaphragm 12 is fixed on the four sides of the rectangular vibration space P, the standing electric diaphragm 12 can only vibrate within the range of the vibration space P. In other words, the effective vibration space of the standing electric diaphragm 12 is limited by the spacer material. 13 limit, resulting in low output volume, and the low frequency cannot be extended

Abstract

The invention discloses an electroacoustic transducer which comprises a stationary electric vibrating diaphragm, an opening plate and a plurality of spacing structures. The spacing structures are arranged between the stationary electric vibrating diaphragm and the opening plate, wherein each spacing structure is provided with at least one main body, and the number of the main bodies is a positiveinteger. When the number of the main bodies is larger than one, the main bodies are respectively connected with a central point and are radially extended outwards.

Description

technical field [0001] The invention relates to an electroacoustic transducer, in particular to an electroacoustic transducer with better output volume and low frequency extension effect. Background technique [0002] The spacer material included in the electro-acoustic transducer is used to separate the static diaphragm from the perforated plate, so as to maintain the vibration space of the static diaphragm, so that after the electro-acoustic transducer is energized, the static The diaphragm can vibrate and produce sound according to the input audio. [0003] figure 1 It is a schematic diagram of an existing electro-acoustic transducer. In the existing electro-acoustic transducer 10, the spacer material 13 is usually in the shape of a grid, and is protruded on the perforated plate 11. When the static diaphragm 12 is arranged on the perforated When it is on the plate 11 , the stationary diaphragm 12 is in contact with the grid-shaped spacer material 13 , leaving a rectangu...
