Description

Vertical type frequency-halving sound box structure

Technical Field

The utility model relates to a technical field of audio amplifier, concretely relates to vertical frequency division by two audio amplifier structures.

Background

Sound is a sound wave generated by the vibration of an object, belongs to a wave, and is a wave phenomenon which is transmitted through a medium (air or solid or liquid) and can be sensed by human or animal auditory organs. The tweeter works in a relatively sharp tone range and is in a high working frequency state, the tone directionality is very strong, and the direction of the tweeter is easy to judge by human ears; the middle-tone loudspeaker relatively works in a range with moderate tone, is a loudspeaker with a sound theme part, has moderate vibration speed, is easy to distinguish when the middle-tone loudspeaker is louder, and is a main part for receiving sound information by human ears; the bass horn works in a very low tone range relatively, but is also the largest power bearing horn, the bass is the part with the largest air vibration amplitude, the touch sense can obviously feel the air vibration, but because of the field pressure with enough strength, the bass can bring the dynamic sense to people, if the bass horn does not sound, the sound is not full enough, and the ears of people are difficult to distinguish. It is known that bass sounds are difficult to distinguish from each other in the case of noise, and are one of the criteria for detecting the tone balance of a sound box.
