Problems solved by technology
Existing loudspeakers mostly receive audio signals through a single plate to drive the diaphragm to vibrate, and the sound output is relatively monotonous and lacks variability
At present, although there are speakers that receive audio signals through a bipolar plate to drive the diaphragm to vibrate, the diaphragm structure of this type of speaker makes it difficult to reduce its weight and thickness
Since the thickness of the diaphragm is the key to affecting the fineness of the sound quality, it is difficult for speakers with low power output to express the details of the sound

Embodiment Construction
[0055] figure 1 It is a schematic diagram of a speaker unit according to an embodiment of the present invention. see figure 1 , the speaker unit 100 of this embodiment can be applied to earphones, external speakers or other audio output devices, but the application of the speaker unit 100 is not limited to the above. The speaker unit 100 of this embodiment includes a first pole plate 110, at least one first spacer 120, a first diaphragm 130, at least one second spacer 140, a second diaphragm 150, at least one third spacer 160 and a second plate 170.
[0056] The first plate 110 is used for receiving an audio signal. Each first spacer 120 includes a first surface 122 and a second surface 124 opposite to each other. The first surface 122 of the first spacer 120 is in contact with the first pole plate 110 . The second surface 124 of the first spacer 120 contacts one surface of the first diaphragm 130 . The second spacer 140 includes a first surface 142 and a second surface 1...

The invention provides a loudspeaker unit comprising a first electrode board, a first spacer, a first vibrating diaphragm, a second spacer, a second vibrating diaphragm, a third spacer, and a second electrode board. The first electrode board comprises a first conductive layer. The second electrode board comprises a second conductive layer. The first vibrating diaphragm and the second vibrating diaphragm are arranged between the first electrode board and the second electrode board. The first spacer contacts the first conductive layer and the first vibrating diaphragm. The second spacer is arranged between the first vibrating diaphragm and the second vibrating diaphragm. The third spacer contacts the second conductive layer and the second vibrating diaphragm. The first conductive layer and the second conductive layer are used for receiving an audio signal. The first vibrating diaphragm and the second vibrating diaphragm are used for vibrating with respect to the first electrode board and the second electrode board according to the audio signal in order to generate corresponding voice.
Description
technical field [0001] The present invention relates to a speaker unit, and in particular to a speaker unit with a double-diaphragm structure. Background technique [0002] The two most direct sensory responses of human beings are the visual and auditory systems, so for a long time, scientists have made great efforts to develop related components or system technologies. At present, the classification of electroacoustic speakers is mainly divided into direct and indirect radiation types, and the driving methods are roughly divided into dynamic, piezoelectric and electrostatic speakers. No matter what kind of loudspeaker, its components can be mainly divided into plate, diaphragm and sound cavity. [0003] In detail, the diaphragm can include an electret layer. After the electret layer is charged, it can generate a static electricity effect inside the material. The polar plate is used to receive audio signals and generate an attractive or repulsive force with the charge of th...
