Product description:
Piezoelectric ceramic peaker features and advantages:
Piezoelectric ceramic speaker: referred to as piezoelectric speaker, the structure is relatively simple, the electro-acoustic conversion rate is high, and there is no magnet. It is a very valuable electro-acoustic device. It is mainly composed of piezoelectric ceramic sheet + paper cone + speaker frame. (Better contains coils inside).
Advantages and characteristics: clear sound, good high frequency characteristics, crisp treble, light weight, high sensitivity, high efficiency, low power consumption. (rated power: piezoelectric speakers are capacitive devices, generally not rated power as a consideration. Take the withstand voltage value as the basis for consideration. Therefore, piezoelectric speakers all talk about withstand voltage but not power!)
Notice:
1: When using piezoelectric speakers, keep away from high temperature, because the crystal in the piezoelectric ceramic speaker will reduce its performance after being exposed to high temperature. The volume of the pronunciation will become smaller!
2: When inspecting the paper cone during maintenance, only press the paper cone of the piezoelectric ceramic horn, but not the piezoelectric ceramic sheet, otherwise the piezoelectric ceramic sheet will be easily crushed!
Speaker type: Tweeter
Panel size: 4 Inch / 97mm
Effective power: 30W
Maximum audio power: 100W
Audio response: 2KHz-20KHZ
Resistance: 4-8Ω
Tweeter: 50 mm
Features: suitable for any subwoofer sound, etc.
Connection method:
1, on the high-pitched output interface
2. Cut off the joint and solder the two wires directly to the positive and negative poles on the horn.
3. Cut off the connector and solder the two wires directly to the audio signal output line of the amplifier.
4. When installing the tweeter, do not pull the two wires of the tweeter first; the two wires of the tweeter are not divided into positive and negative.
Note:
1.The sound of high-pitched hair is “zhi zhi” high-pitched sound, the instrument sounds loud, the human voice is small, and the sound is sharp. The main function of the treble head is to improve the high-pitched sound quality. The high-pitched head must be used with a subwoofer or a full-range horn. It cannot be used as a separate listening song!
2.The size of the product is measured by hand and may have an error of ±2mm.
Package included:
2Pcs Piezoelectric Tweeter
