Description
Technical field
The present invention relates to loudspeaker technical field, more particularly, to a kind of Ultrathin speaker and its portable audio.
Background technology
Loudspeaker, also known as speaker, are a kind of electroacoustic transducers, and it converts electrical current into into acoustic energy by certain physical effect.When
When different electron energies reaches the voice coil loudspeaker voice coil of loudspeaker, voice coil loudspeaker voice coil produces the magnetic field interaction of a kind of energy and Magnet, and this interaction causes
Diaphragm oscillations, because electron energy changes at any time, the voice coil loudspeaker voice coil of loudspeaker can move forward or backward, and the therefore vibrating diaphragm of loudspeaker will be with
Motion, this action makes the density degree of air produce change and produce sound.
It is applied to the video fields such as television set, display and notebook computer with LED technology, video equipment constantly chases after
Seek minimal thickness, image quality is also further improved simultaneously, because corresponding acoustical quality and power requirement also will have further
Lifting.Generally as shown in figure 1, including the frame 1 extending obliquely upward, terminal board 2 is arranged on basin to the structure of conventional horn
On the muscle position of frame 1 lower surface, T ferrum 11 is arranged on the bottom of frame 1, is provided with Magnet 3 in T ferrum 11, and washer 4 is bonded in Magnet 3
