As shown in Figure 1A to Fig. 6, be the audio sheet 10 according to preferred embodiment of the present utility model, described audio sheet 10, under the effect a vibrational system, carrying out vibrating function, shakes to produce sound thereby drive described audio sheet 10 ambient airs.Such vibrational system is returned system as voice coil loudspeaker voice coil and the magnetic of loud speaker.In a further embodiment, described vibrational system can be other whole loud speaker, and described audio sheet 10 is used to described other whole loud speaker to produce auxiliary audio, and its execution mode will specifically describe hereinafter.
Described audio sheet 10 comprises the vibrating elements 11 in the middle of being positioned at, and is located on described vibrating elements 11 an elastic suspended limit 12 on every side, and a framework 13, and described outstanding limit 12 is arranged between described vibrating elements 11 and described framework 13.Because described outstanding limit 12 is to make with elastomeric material, thereby when described audio sheet 10 during in a vibrational energy field, while namely, vibration wave being arranged, under the effect of the energy waves produced as the vibrations by air, described vibrating elements 11 will vibrate under the drive on described outstanding limit 12, thereby produces sound.
Figure 1A and Figure 1B illustrate the positive back side of described audio sheet 10 from both direction.Can find out, described outstanding limit 12 is accordion and extends between described vibrating elements 11 and described framework 13, rather than entirely be arranged between described vibrating elements 11 and described framework 13, like this, described outstanding limit 12 is actually for driving described vibrating elements 12 vibrations and can make again described vibrating elements 12 generations rock, and makes audio distortions.
Particularly, according to above preferred embodiment, as shown in Figure 1A, described outstanding limit 12 comprises a stretched portion 121 and a buffer portion 122, described stretched portion 121 extends the outward flange 111 of described vibrating elements 11 integratedly, and stretches out, as curvedly stretched out.Described buffer portion 122 extends from described stretched portion 121 integratedly, and extends towards inboard.That is to say, described buffer portion 122 stretches out and is connected to form the outstanding limit 12 of described accordion with described stretched portion 121 from the inner surface 131 of described framework 13.
In this preferred embodiment, also can say, described stretched portion 121 forms domes with described buffer portion 122, and described stretched portion 121 is all encircled and is located at around described vibrating elements 12 with described buffer portion 122.The contiguous described vibrating elements 11 of wherein said stretched portion 121, and the contiguous described framework 13 of described buffer portion 122.As shown in Figure 1B, described stretched portion 121 and described buffer portion 122 form a cannelure 123 at the another side of described audio sheet 10 between described vibrating elements 11 and described framework 13.
