Car horn points have electric horn and two loudspeakers

Car horn points have electric horn and two loudspeakers, electric horn by electromagnetic coil electricity and power continuously, make the metal diaphragm produces vibration and acoustics, sound pleasing to the ear. Electric horn shape is a spiral and basin type, widely used in all kinds of cars. Light passenger cars are electric horn. Air TV Speaker using compressed air flow make the metal diaphragm produces vibration, appearance is more long horn (cylindrical), more sound and a higher tone, long transmission distance, multi-purpose on running a long distance of large and medium-sized cars within the city is disabled. Spiral car electric horn attached speaker cone, roll up into a spiral in a compressed volume, beautiful sound loud and clear. Basin shape car electric horn without speaker cone, shape flat small volume, light weight and easy installation, quality slightly but widely used. Basic working principle of spiral and basin shape is the same, is Computer Speaker by iron core (1), (2) the magnetic coil, contact (6), the armature (5), diaphragm (3), etc. When the driver presses the button (8), electricity flows through the contact through the coil, a coil magnetic suction under the armature (5) mandatory diaphragm moving armature move off contact, magnetic current interrupt disappear, elastic diaphragm in itself and under the action of leaf spring and recovery in situ with armature, contact closure circuit connected to electric current to pass through magnetic coil, contact the repeat the action. So follow bad diaphragm vibration unceasingly, thus the sound. The soundboard (4) and diaphragm rigid connection, can make the vibration smooth sound more pleasing to the ear. Car horn on high frequency with high, medium and low bass three. In order to make the car horn tone more plump, some electric horn of the car horn and got behind the tones of high and low, form a dual tone horn. But this current is bigger, will directly endanger the button contact. In order to avoid the horn button contact is arc spark burn out, some car in line to join a relay, with a small current to control large current, make the horn button only from damage by small current. Need to point out that the positive line (7) of the average car horn is supplied by the fuse box, anode electric horn button is the control of the car horn, so commonly known as the horn button line for the "system". General motors electric horn of tone and volume can be adjusted, by adjusting the gap between armature and core adjustable tones, adjust the contact pressure adjustable volume, once the volume, coil current changes. In order to keep the sound volume, there are some electric horn is fully sealed, are not allowed to adjust, change is broken as a whole.

Medium mixed sound resonance

Medium mixed sound resonance, sound principle, USES a vibrator vibration sound + paper eardrum trumpet sound, we often use the stereo knows that, in addition to the ordinary acoustics professional audio, general average sound heavy bass is not enough, the bass better generally have no small volume, this is mainly due to the adoption of the horn TV Speaker sound affected by voice unit cell size is very big, so a lot of multimedia audio directly USES the subwoofer, external speakers, fully expand the scope of its sound unit cell volume, but it have a lot of restriction for the Wooden Computer Speaker of the stereo sound, that is why we see stereo in the market are generally four directions, four is the cause of the angular and bass effect is not very good. Combined sound exactly is the integrity of the manufacturers of the stereo set machine, its function as complete as possible, easy to use, look gorgeous. All part of the combined sound, such as speakers, amplifiers, booth and CD are provided by the manufacturer, is to cooperate on the whole, and are more uniform in shape, beautiful; After buying customers don't need to spend a lot of time debugging, generally can be used directly, more convenient in operation, function is relatively complete. Many people believe that the quality of the audio system is not high, but in fact, with the development of electronic technology, the performance of the combined sound also have greatly improved, therefore, for the majority of users, combined sound has been completely can meet the need. Combined sound of price, quality, performance, of course, there is a great gap, have one thousand yuan level of products, also have ten thousand yuan of products, need to which kind of, can according to customer's own economic strength and the demand for choice. When there is a tree in the forest fell down, gave a crashing the loud voice, but no one in the virgin forest, so I can't hear the sound. This is not a voice out? The sound come is for sure, because when the trunk and branches of the contact with the ground, they will produce certain sounds, but no one heard, but heard this voice for humans or other animals is different, so this is what is said in the acoustic psychological (Psychoacoustics).
