SPEAKER? is a micro-speaker that comes with the chassis. To put it simply, it is a speaker.
A speaker is a transducer device that converts electrical signals into acoustic signals. The performance of the speaker has a great impact on the sound quality. The speaker is the weakest component in audio equipment, and it is also the most important component in terms of sound effects.
There are many types of speakers, and their prices vary widely. Audio power uses electromagnetic, piezoelectric or electrostatic effects to cause its paper cone or diaphragm to vibrate and vibrate with the surrounding air (chirp) to produce sound.
Low-end plastic speakers have no sound quality due to their thin cabinets, inability to overcome resonance (some well-designed plastic speakers are far better than inferior wooden speakers); wooden speakers reduce the size of the cabinet The sound quality caused by resonance is generally better than that of plastic speakers.
Extended information:
The parameters of the loudspeaker refer to the specific performance parameter values ??of the loudspeaker tested using a dedicated loudspeaker testing system.
The loudspeaker parameters The main performance indicators include: sensitivity, frequency response, rated power, rated impedance, directivity, distortion and other parameters.
The power of the speaker is divided into nominal power and maximum power. Nominal power refers to rated power and undistorted power. It refers to the maximum input power allowed by the speaker within the rated non-distortion range. The power marked on the speaker's trademark and technical manual is the power value. Maximum power refers to the peak power that the speaker can withstand at a certain moment. In order to ensure the reliability of the speaker operation, the maximum power of the speaker is required to be 2 to 3 times the nominal power.
The impedance of a speaker is generally related to frequency. The rated impedance refers to the impedance measured from the speaker input when the audio frequency is 400Hz. It is generally 1.2~1.5 times the DC resistance of the voice coil. Generally, the common impedances of moving coil speakers are 4Ω, 8Ω, 16Ω, 32Ω, etc.
