描述

本產品是一種揚聲器套件,通過使用超聲波具有尖銳的指向性。它只發送一個聲音。它有許多波發射機。請注意,你需要焊接很多點來組裝它。

焊接後:


零件清單

  • 1 x 放大器 PCB(組裝)

  • 1 個揚聲器 PCB(未組裝)

  • 49 個波形發射器

  • 1 個揚聲器 PCB 電感

  • 1 個揚聲器 PCB 連接器

  • 1 個放大器 PCB 到揚聲器 PCB 的連接電纜

  • 1 x 滑動放大器 PCB 的電源開關

  • 電源輸入:DC 12V,1A

  • 外徑 5.5mm,內徑 2.1mm

  • 中心正向,桶負向

  • 音頻輸入:3.5mm 立體聲迷你插孔

  • 最大驅動波發射器:100pcs(如果您使用超過 50pcs,您需要使用 2A AC 適配器)

注意事項

  • 波發射機具有極性。您需要安排變送器和 PCB 的正面符號。

  • 電感器沒有極性,但為了能夠使用多種類型的電感器,PCB 有多個孔。您可以將電感器的兩個引腳插入由兩個紅色圓圈包圍的孔中。

  • 並且您需要將連接器焊接到 PCB

  • PCB 的正面有用於檢查變送器極性的孔。

  • 您需要將發射器焊接到 PCB 而沒有間隙。如果它有差距,則無法展現最佳性能,因為它無法對齊發射機的方向。

Description

This product is a speaker kit which has a sharp directivity by using ultrasound. It sends a sound only straight. It has many wave transmitters. Please note that you need to solder many points for assembling it.

After soldering:


Part List

  • 1 x Amplifier PCB (assembled)

  • 1 x Speaker PCB (not assembled)

  • 49 x Wave transmitters

  • 1 x Inductor for the speaker PCB

  • 1 x Connector for the speaker PCB

  • 1 x Connection cable for the amplifier PCB to the speaker PCB

  • 1 x Slide power switch for the amplifier PCB

  • Power input: DC 12V, 1A

  • Outer diameter 5.5mm, Inner diameter 2.1mm

  • Center-positive, Barrel-negative

  • Audio input: 3.5mm Stereo mini jack

  • Max driving wave transmitter: 100pcs (If you use over 50pcs, you need to use 2A AC adaptor)

Cautions

  • Wave transmitters have a polarity. You need to arrange the positive symbol of the transmitter and the PCB.

  • Inductor dose not have a polarity, but in order to be able to use the inductor of several types, the PCB has several holes.You can insert the two pins of an inductor into either holes enclosed by two red circles.

  • And you need to solder the connector to the PCB

  • The positive side of the PCB has holes for checking the polarity of a transmitter.

  • You need to solder the transmitters to the PCB without a gap. If it has a gap, it is not possible to exhibit the best performance, because it cannot align the direction of the transmitters.
