Further, be provided with the ultralow frequency loud speaker in described the 3rd chamber.
Further, described second chamber and described the 3rd chamber and interior described ultralow frequency loud speaker thereof constitute the ultralow frequency system.
Further, independent input signal can separately be distinguished by described full range system and described ultralow frequency system.
Further, described full range system and described ultralow frequency system can the same signals of back input in parallel.
Compared with prior art, the utility model by a chamber and be located at loud speaker in it and another chamber in Horn constitute full range, constitute ultralow frequency by the loud speaker in former and later two chambers and the chamber located therein, full range and ultralow frequency are combined in the audio amplifier, fully having reduced ultralow frequency and the full range frequency in same frequency range interferes, increased ultra-low frequency compensation, make that the frequency range of audio amplifier is wideer, lower-frequency limit is lower, reduce the volume of audio amplifier simultaneously, it is littler to take up room, conveniently laying.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
See also Fig. 1, the utility model has disclosed a kind of novel audio amplifier 1, comprises casing 11, is provided with two baffle plates that described casing 11 are divided into three chambers in the described casing 11.
Described two baffle plates comprise first baffle plate 12 and the second baffle 13 that intersects vertically with described first baffle plate 12.Described first baffle plate 12 forms first chamber 14 and second chamber 15 with the inwall of described casing 11, and described second baffle 13 forms the 3rd chamber 16 with the inwall of described casing 11.Described first chamber 14 and described second chamber 15 are positioned at the front side of described casing 11, and described the 3rd chamber 16 is positioned at the rear side of described casing 11.
Be provided with full frequency speaker 17 in described first chamber 14, described full frequency speaker 17 can be contained the frequency of 50-25000Hz in recent years.The loud speaker of being located in described second chamber 15 is a Horn 18, described Horn 18 discharges through a high proportion of compression back the sound that described full frequency speaker 17 vibrating diaphragms send by an opening bugle that changes from small to big, to obtain higher output acoustic pressure and farther projection distance.Described full frequency speaker 17 in described first chamber 14, described first chamber 14 and the described Horn 18 in described second chamber 15 constitute the full range system.
Described the 3rd chamber 16 is provided with ultralow frequency loud speaker 19, and the described ultralow frequency loud speaker 19 in described second chamber 15, described the 3rd chamber 16 and described the 3rd chamber 16 constitutes the ultralow frequency system.Described ultralow frequency loud speaker 19 can send the low-frequency sound of 20-200HZ usually, and when energy was not very strong, people are more unpleasant to hear to arrive, and was difficult to distinguish sound bearing.The diameter of described ultralow frequency loud speaker 19 vibrating diaphragms is bigger, and increased the equipment that is used for reaching resonance effect, and the bass that people hear can be felt very shock.
