The Way The Speaker Is Placed
There are many types of speakers: according to its conversion method can be divided into electric, electromagnetic, piezoelectric, digital and other; according to the diaphragm structure can be divided into single cone, composite cone, compound horn, with the same Shaft, etc., Speaker according to the beginning of the diaphragm can be divided into cone-type, the top of the ball, flat, belt and other; according to the playback frequency can be divided into high frequency, intermediate frequency, low frequency and full band speaker; Can be divided into external magnetic, internal magnetic, dual magnetic and shield and other types; according to the magnetic properties can be divided into ferrite magnets, neodymium boron magnets, aluminum nickel cobalt magnet speakers; Speaker Sub-paper and non-paper cone speakers.
The speaker placed in different positions, will directly affect the balance of the speaker sound, creating a sound field depth, heavy bass effect and midrange sound quality. The correct placement method is man-centered, first symmetrically to the speaker to adjust the position, and then a small amount of fine-tuning, Speaker until the sound is smooth, soft, naturally so far .....
People are listening to the main body, placing the speaker position is naturally related to the location of the listener. In general, people should be on the vertical bisector of two speaker lines, and the distance from the speaker to the loudspeaker should be greater than the distance between the two speakers. As for the two speakers should be far apart, to 1 m ~ 1.5 m for the lower limit, the room varies from person to person. Speaker If they are placed on both sides of the audio equipment, the spacing is clearly too small, so create a sound field is too narrow. Of course, this time the ears from the speaker too close to hear the direct sound-based, wall reflection, supplemented by sound. As the ordinary speakers are used in a passive way of frequency, frequency network must contain capacitors, bass drive unit, there are 90 degrees of phase difference, the two drive unit issued by the sound is not synchronized in theory, so that people The closer the speaker is, the more obvious the effect, but the average person is difficult to detect. In addition, the speakers are too close, can clearly hear the bass from two different drive unit, get the sound is not natural, not harmonious. People and speakers away from a certain distance, Speaker directly hear the sound and reflection sound can be effectively integrated, and effectively feel the sound field width and depth, hear the sound can be more gentle and natural.
It is important to keep a certain distance between the speaker and the loudspeaker, because these sounds must be opened in front of the loudspeaker in order to form a depth, Speaker the distance is too close, the sound will be greatly reduced. So, if the use of bookshelf speakers should be high? Most of the loudspeaker sound will be with the location of the level of change, do not believe you can try; first put it on the ground to listen, and then put on the table, the two hear the sound is very different of. Bookcase speakers to be placed on the table is appropriate, seat speakers on the ground is appropriate, the height of the bass unit as much as possible to improve, the best high / bass unit as close as possible, tweeter and listeners binaons in the same level on. This is why some seat-type speakers are designed to surround the woofer at the top of the tweeter. The orientation of the loudspeaker is different depending on the placement of the sound, the center / treble part of the sound, the knot of the sound field, Speaker and the width of the sound space of the listener feel varying in varying degrees.
The toe-in angle of the loudspeaker also affects the ratio of the direct sound to the reflected sound. When the speaker toe-in angle, so that the speaker has a better performance, then the sound of energy is directed to the listener, although the sound field narrowed, but it can increase the sound of the knot, the sound more clear, But also to reduce the toe-in angle, people will hear more from the wall of the reflection of the sound, feel a greater sound field range, the sound field of the depth of space is also a sense of the depth of the sound field Has been enhanced. When the speaker is flat, the toe-in angle is zero, the treble is smooth, but the knot may be somewhat ambiguous, the sound field is also widened, but will lack the fine place.
In short, the orientation of the toe-in angle is a compromise that follows the design characteristics of the loudspeaker, the performance, the size of the room, and the personal preference of the listener. For some speakers, people and speakers into the isosceles triangle position, the highest treble to hear the most, so the angle is too large placement will increase the effect of treble, it is not necessary, Speaker everything should be According to the actual situation. After grasping the toe-in angle, also pay attention to the two speakers at the same time toe-in angle should be consistent, otherwise the sound of the best point will be a clear shift.
The walls of the room reflection, the overall effect of the sound naturally have no small effect. The loudspeaker is near the wall, and the bass sound waves are heard by the walls after being reflected by the walls, and the low-frequency part of the sound waves that it emits is more effective in driving the surrounding walls to vibrate with the speakers so that the bass portion of the sound will be strengthened The sound is more vigorous and full of appeal. So the speaker closer to the corner placed, people hear the bass effect is stronger.
