According to technical scheme of the present invention, audio amplifier can be installed in the television set outside, and is therefore better than the tonequality of television internal loud speaker.In addition, loud speaker is installed in the airtight cavity, has avoided the sound of the loudspeaker plays of two cavitys to interact, and has improved tonequality further.When the list structure of this audio amplifier made its below that is installed in panel TV, profile can be mated preferably with television set.Therefore adopt technical scheme of the present invention can take into account the tonequality of audio amplifier and the profile coupling of audio amplifier and television set.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part, and illustrative examples of the present invention and explanation thereof are used to explain the present invention, do not constitute improper qualification of the present invention.In the accompanying drawings:
Fig. 1 is the schematic diagram according to the loudspeaker box structure of the embodiment of the invention;
Fig. 2 is the schematic diagram according to the television structure in the embodiment of the invention.
Embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Fig. 1 is the schematic diagram according to the loudspeaker box structure of the embodiment of the invention.
As shown in Figure 1, audio amplifier global shape among the present invention is bar shaped, its housing comprises fore shell 11 and back cover 12, circuit board 13, at least two loud speakers 14 are arranged in the audio amplifier, and play two muscle on the back cover 12 of this audio amplifier, i.e. muscle among the figure 151 and muscle 152, these two muscle are divided into three cavitys along its length with audio amplifier, as shown in FIG. cavity 1A, 1B and 1C.Shown in Fig. 1 is the situation that fore shell separates with back cover, and in use, front and rear casing snaps together, thereby makes the cavity 1A on both sides and 1C form airtight cavity, and a plurality of loud speakers 14 are installed in respectively in these two airtight cavitys.
This audio amplifier is owing to being installed in the television set outside, and is therefore better than the tonequality of television internal loud speaker.In addition, loud speaker is installed in the airtight cavity, has avoided the sound of the loudspeaker plays of two cavitys to interact, and has improved tonequality further.When the list structure of this audio amplifier made its below that is installed in panel TV, profile can be mated preferably with television set.Therefore, the audio amplifier of present embodiment can be taken into account the tonequality of audio amplifier and the profile coupling of audio amplifier and television set.
Among cavity 1A and the 1C, the interior loud speaker of cavity is used to play L channel, and the loud speaker in the cavity of another side is used to play R channel.Because of these two cavitys are airtight,, make audio amplifier that preferable tonequality be arranged so left and right acoustic channels is independent of each other.
Among the cavity 1B in the middle of circuit board can be installed in, this cavity is breathed freely, and for example can punch on its shell.Ventilating structure helps to guarantee the good heat radiating of circuit board.
The lead-in wire of circuit board penetrates airtight cavity 1A and is connected with 1C and with loud speaker, and perforation is by the encapsulant sealing, to guarantee the seal of cavity 1A and 1C.
Fore shell 11 and back cover 12 can adopt the one injection molded respectively, and this mode is easily manufactured, and cost is lower.
Can place acoustical cotton among cavity 1A and the 1C, to improve the tonequality of audio amplifier.
Can also place passive radiator among cavity 1A and the 1C,, thereby strengthen its audio with the LF-response of raising audio amplifier.Can comprise frequency dividing circuit in the circuit board 13, audio frequency is divided into high pitch part and bass part, correspondingly, the loud speaker 14 among cavity 1A and the cavity 1C can be respectively to be two groups, plays high pitch and bass respectively for every group.This form helps to strengthen the audio of audio amplifier.In addition, frequency dividing circuit can also be placed among cavity 1A and the 1C except being placed in the circuit board 13, and can three frequency division, like this, places bass, middle pitch, three loud speakers of high pitch in cavity 1A and the cavity 1C.
Below the television set in the embodiment of the invention is made an explanation.
Fig. 2 is the schematic diagram according to the television structure in the embodiment of the invention.
As shown in Figure 2, the television set in the embodiment of the invention comprises television set body 21 and audio amplifier 22.Wherein audio amplifier 22 can be connected with television set body 21 by jockey 23, as shown in Figure 2; For wall-hanging TV, audio amplifier can be fixed on the wall by independent hanging set.The audio output line of television set is connected with circuit board 13 in the audio amplifier.
The thickness of audio amplifier 22 should adapt with the thickness of television set body, makes the outward appearance of television set integral body comparatively coordinate.The distance of audio amplifier fore shell and back cover can be 30mm～100mm.In general, the distance of audio amplifier fore shell and back cover can only be slightly larger than television set thickness, and is no more than 100mm.For example, the television set body thickness is 50mm, and then audio amplifier preferably is no more than 80mm; If the television set body thickness is 37mm, then audio amplifier preferably is no more than 70mm; If the television set body thickness is 80mm, then audio amplifier preferably is no more than 100mm.
When the list structure of audio amplifier 22 made its below that is installed in television set body 21, profile can be mated preferably with television set body 21.Therefore, the television structure of present embodiment can be taken into account the coordination of tonequality and outward appearance, is particularly suitable for the wall hanging type flat plate TV.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
