Abstract
The utility model discloses a built-in sound box. The built-in sound box comprises a box body, wherein the box body is internally provided with a high frequency loudspeaker and a low frequency loudspeaker, the box body is provided with a low frequency loudspeaker sound outlet, an upper portion of the low frequency loudspeaker is provided with a sound guide board, the sound guide board and the low frequency loudspeaker sound outlet form a chamber, and an opening direction of the chamber and a direction of a sound outlet of the high frequency loudspeaker are consistent. The built-in sound box guarantees integral thinness of flat video equipment, the sound guide board is utilized to reflect low frequency sound waves emitted by the low frequency loudspeaker, so the low frequency sound waves and high frequency sound waves have consistent propagation directions, and thereby sound effect quality of the flat video equipment can be improved.
Description
Technical field
The utility model relates to a kind of audio amplifier, particularly a kind of audio amplifier that is built in the dull and stereotyped video equipment.
Background technology
Along with the development of lcd technology, dull and stereotyped video equipments such as smart mobile phone, LCD TV advantage little with its volume, that be convenient for carrying is subjected to more and more consumers' favor.The thickness of dull and stereotyped video equipment is thinner relatively, when carrying out the design of dull and stereotyped video equipment complete machine usually with woofer and tweeter towards vertical setting mutually, be of value to the thickness that reduces dull and stereotyped video equipment although it is so, but when a loud speaker towards the user time, another certainly will be perpendicular to the user's, because the directive property that sound wave is propagated, the sound wave that the loud speaker that arranges perpendicular to the user sends has decay by a relatively large margin, directly has influence on the audio quality of dull and stereotyped video equipment.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of built-in speaker, to reach the purpose that improves dull and stereotyped video equipment audio quality.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of built-in speaker, comprise casing, be provided with tweeter and woofer in the described casing, described casing is provided with the woofer sound mouth, described woofer top is provided with the leading note plate, described leading note plate and described woofer sound mouth form cavity, and the opening direction of described cavity is consistent with the sound mouth direction of described tweeter.
Preferably, be provided with L type dividing plate between the inherent described tweeter of described casing and the described woofer.
Pass through technique scheme, a kind of built-in speaker that the utility model provides is guaranteeing under the slim prerequisite of dull and stereotyped video equipment complete machine, the low-frequency sound wave that uses leading note plate reflection woofer to send, make the low frequency sound wave consistent with the high frequency audio direction of wave travel, can improve the audio quality of dull and stereotyped video equipment.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below.

Fig. 3 is the cutaway view of A-A direction among Fig. 2.
The represented corresponding component title of numeral among the figure:
1, leading note plate 2, casing 3, woofer 4, opening
5, tweeter sound mouth 6, dividing plate
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
According to Fig. 1 to 3, the utility model provides a kind of built-in speaker, comprise casing 2, be provided with tweeter and woofer 3 in the casing 2, be provided with L type dividing plate 6 between tweeter and the woofer 3, dividing plate 6 is divided into two independent parts with casing 2 inside, on one side as laying tweeter, second half is as laying woofer 3, casing 2 is provided with woofer 3 sound mouths, and woofer 3 tops are provided with leading note plate 1, and leading note plate 1 forms cavity with woofer 3 sound mouths, cavity leaves a side opening 4, and opening 4 directions are consistent with tweeter sound mouth 5 directions.
A kind of built-in speaker that the utility model provides is guaranteeing under the slim prerequisite of dull and stereotyped video equipment complete machine, the low-frequency sound wave that uses leading note plate 1 reflection woofer 3 to send, make the low frequency sound wave consistent with the high frequency audio direction of wave travel, can improve the audio quality of dull and stereotyped video equipment.
To the above-mentioned explanation of disclosed a kind of built-in speaker embodiment, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
Claims (2)
1. built-in speaker, comprise casing, be provided with tweeter and woofer in the described casing, it is characterized in that, described casing is provided with the woofer sound mouth, described woofer top is provided with the leading note plate, and described leading note plate and described woofer sound mouth form cavity, and the opening direction of described cavity is consistent with the sound mouth direction of described tweeter.
2. a kind of built-in speaker according to claim 1 is characterized in that, is provided with L type dividing plate between the inherent described tweeter of described casing and the described woofer.
