Desktop Speaker Strength Of

There are many types of speakers, but the basic working principle is similar, Desktop Speaker are a kind of electrical signal is converted to sound signal for playback components. Currently the most widely used is the electric speaker, which consists of diaphragm, voice coil, permanent magnet, Desktop Speaker bracket and other components.

When the voice coil of the speaker into the audio current after the voice coil in the role of the current will produce alternating magnetic field, the permanent magnet also produces a constant size and direction of the constant magnetic field. Since the size and direction of the magnetic field generated by the voice coil are constantly changing with the change of the audio current, the interaction between the two magnetic fields causes the voice coil to move perpendicularly to the direction of the current in the voice coil, and the voice coil and the diaphragm are connected The vibration of the vibrating diaphragm is generated, and the vibration of the air is caused by the vibrating diaphragm vibration. When the input voice coil current is greater, the greater the force of its magnetic field, Desktop Speaker vibration diaphragm vibration amplitude is greater, the sound is more loud. The loudspeaker part of the loudspeaker is mainly in the center of the diaphragm, and when the center of the loudspeaker diaphragm is harder, Desktop Speaker the sound effect of the loudspeaker is better. The loudspeaker produces a bass part mainly on the edge of the diaphragm, and if the edge of the diaphragm of the loudspeaker is softer and the cone is larger, the loudspeaker sounds better. In addition, the dome speakers in the market today in the use of a lot of speakers. As we all know, Desktop Speaker the tweeter because of its high frequency of operation, in the playback of the treble when the diaphragm will be permanent magnet in the magnetic field air gap for high-speed movement, so the tweeter speaker diaphragm to the transient high-frequency signal Make a quick response. Desktop Speaker And can withstand the high-speed movement of the air pressure, so the production of materials for the diaphragm requires the quality of light, and to have sufficient strength.

 The rated power of the loudspeaker is the output power that the speaker can work for a long time, also known as no distortion power, which is generally marked on the nameplate of the back of the speaker. Desktop Speaker When the speaker is working below the rated power, the coil will not produce overheating or mechanical action overload and so on, the sound is not displayed distortion. Rated power is an average power, and in fact the power state of the speaker work is changed with the input audio signal strength, Desktop Speaker in the dynamic range of large music and sound signals, the sudden peak pulse signal will exceed the rated power Times, because the duration is short and will not damage the speaker, but there may be distortion. Therefore, in order to ensure that the peak pulse appears to still get a good sound quality, Desktop Speaker the speaker need to leave enough power margin. The maximum power of the loudspeaker is 2-4 times the rated power.
