Description

Combined speaker device and sound effect reproducing method

Technical field

The present invention relates to a speaker device, and more particularly to a combined speaker device and sound effect reproducing method.

Background technique

Hi-Fi (High-Fidelity) audio is a sound reproduction device with a high sound level, which is widely used in auditoriums, cinemas, home theaters, recording studios, K-songs and the like. High-fidelity audio has integrated, packaged and combined types. In general, the sound quality of the integrated high-fidelity audio is relatively poor. Therefore, when used in places where high sound quality is required, it will be better. Sound-based packaged or modular hi-fi, and packaged or combined hi-fi that allows users to arrange for better sound as needed, is therefore more popular in the market.

As shown in FIG. 1 is a high-fidelity audio 1P of the prior art. In order to obtain the sound effect of the full audio segment, the high-fidelity audio 1P often needs to provide a large vibration cavity to obtain a lower low frequency. The high-fidelity audio 1P requires a high-power input for driving the high-frequency, intermediate-frequency, and low-frequency horn vibrations to generate sound effects when playing the sound effect, in order to avoid the high-fidelity sound 1P due to its own vibration in the process. The phenomenon of "walking", vibration, etc., causes the hi-fi 1P to be designed in consideration of its own weight and volume, that is, in general, the hi-fi 1P having a large volume and its own weight. The less likely to generate vibration and "walking", however, the high-fidelity 1P of such a large volume and large self-weight has defects such as in actual use to cause inconvenience in use.

For example, when arranging the hi-fi 1P, one method is to fix the hi-fi 1P on a wall to reduce the effective space occupied by the hi-fi 1P, but since the hi-fi 1P has The large self-weight, and the vibration of the hi-fi 1P itself caused by the vibration of the horn, causes the hi-fi 1P to shake, and the shaking not only causes the occurrence of noise but also makes the sound impure, and Long-term shaking can also cause the hi-fi 1P to fall off from a fixed position, causing unnecessary loss. Another method is to support the hi-fi 1P to a certain height with a bracket, but the bracket itself is more likely to sway during the occurrence of the hi-fi 1P.

In addition, the structural design of the hi-fi 1P is relatively complicated, and the input of high-power energy is more likely to cause breakage of a fragile structure such as a hanging edge. When the component of the high-fidelity sound 1P is damaged, there is no Under the assistance or operation of a professional, the user cannot repair or replace the corresponding damaged component, so that the high-fidelity 1P provided by the prior art will have higher maintenance cost and use cost in the subsequent process.
