Micro speaker with air adsorbent |
| abstract |
Provided is a microspeaker that can improve the excellent low-frequency characteristics regardless of the aluminum mass ratio with respect to silicon as an air adsorbent as well as reducing the manufacturing unit cost. In a micro speaker including an enclosure (200), a speaker unit (100) received in the enclosure, a resonance space defined between both, and an air adsorbent provided in the resonance space, air adsorption is provided. The agent consists of a zeolite having a channel (tubular pore) having a size of 0.4 nm to 0.6 nm of 35% or more in the entire channel. [Selection] Figure 1 |
