Description

Speaker with both playback and amplifier effects

technical field

The utility model relates to the technology in the field of sound boxes, in particular to a sound box with both playback and power amplifier effects.

Background technique

With the improvement of people's living standards, home theaters are becoming more and more popular among young people. The so-called home theater is a system that combines audio and video equipment, so that you can experience and feel the theater atmosphere that can be created in the home environment; And speakers, where the speaker has a single function, and usually consists of a pair of main speakers, a pair of surround speakers, a center speaker and a subwoofer. Such a huge structure not only takes up space, especially The high cost makes ordinary consumers discouraged, and thus cannot be popularized in the market.

Utility model content

The utility model aims at the deficiency of the above-mentioned conventional technology, and the main purpose is to provide a multi-functional sound box with both playback and power amplifier effects.

In order to achieve the above-mentioned purpose, the utility model takes the following technical solutions:

A sound box with playback and power amplifier effects, comprising a box body, a speaker group and a player are embedded on the panel of the box body, each speaker in the speaker group is connected to a power amplifier, and the power amplifier is connected to the The signal processor in the box body is connected with the electrical signal, and the signal processor is connected with the player with the electrical signal.

The above-mentioned speaker set includes a subwoofer, a main channel speaker and a surround channel speaker.

The main channel speaker and the player are arranged on the front panel of the cabinet together.

The player is a slot-in or tray-type structure.

The player is a DVD player or a VCD player or a CD player.

Compared with the conventional technology, the utility model has the beneficial effect that the loudspeaker group, the player, the power amplifier and the signal processor are integrated into one structure in the same box, and it can create a family environment atmosphere along the design mode of the simulated home theater. In addition, there is no need to purchase players, power amplifiers, and single-function speakers independently, so the cost is low, the use is convenient, and the space occupied can be reduced, which is suitable for the needs of consumers.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

Please refer to Fig. 1 and shown in Fig. 2, a kind of sound box with playback and power amplifier effect concurrently, comprises box body 1, loudspeaker group 2, player 3, power amplifier 4 and signal processor 5, present embodiment uses 3.1 sound channels The system is taken as an example for illustration, where:

The speaker set 2 is composed of a subwoofer 21 and a main channel speaker, wherein the main channel speaker includes a left speaker 22, a right speaker 23, and a middle speaker 24, and the middle speaker 24 is interposed between the left speaker 22 and the right speaker 23. between. Wherein, the left horn 22 and the right horn 23 are embedded on the front panel 11 of the box body 1, and the left horn 22 and the right horn 23 are arranged at an oblique angle with the middle horn 24 respectively; Embedded in the inclined groove 12 provided on the front panel 11 ;

The player 3 can be a slot-in or tray-type DVD/VCD, wherein the player 3 is embedded on the front panel 11 of the cabinet 1 .

The power amplifier 4 is fixed in the box body 1 , and each speaker is connected to the power amplifier 4 .

The information processor 5 is used to process the electrical signal output by the player 3 and then provide each power amplifier 4 to work. The information processor 5 can be an IC chip, which adopts the existing programming technology and will not be described in detail here. Wherein, the information processor 5 provides an electrical signal connection with the player 3 on the one hand, and provides an electrical signal connection to each power amplifier 4 on the other hand; of course, the information processor 5 and each effector 4 can be integrated on the same circuit board 6, without limitation here.

As shown in Figure 2, the working principle of the above-mentioned embodiment is: when the player 3 is turned on, the output signal of the player 3 is received by the information processor 5, and is sent to each power amplifier 4 after processing, and then is sent to each power amplifier 4 by each power amplifier 4. After the signal is amplified, it is input to each speaker connected accordingly, and then the purpose of the sound effect is realized by each speaker; in terms of the overall connection of this circuit, it is a conventional circuit connection technology, and the design focus of the utility model is to connect the speakers in the same box 1 Group 2, player 3, power amplifier 4, and information processor 5 are integrated into one structure, which can achieve the effect of creating a home environment atmosphere along the analog home theater design method, and does not need to purchase players, power amplifiers and single-function devices independently. The sound box has low cost and can reduce the occupied space, which is suitable for the needs of consumers.

The above is only a preferred embodiment of a sound box with both playback and power amplifier effects in the present invention, and does not limit the technical scope of the present invention. For example, the speaker group 2 can increase the surround sound in the above-mentioned embodiment. The purpose of the utility model can also be realized by adopting a 5.1-channel system mode design for the composition of the speakers, so any minor modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the utility model still belong to the technology of the utility model within the scope of the program.
