Description

Wireless Bass Sound System for Electronic Devices

【Technical field】

The present invention relates to a wireless subwoofer sound system, and in particular to a wireless subwoofer sound system of an electronic device.

【Background technique】

Traditional TVs usually only have left and right speakers for stereo sound. However, because the built-in speakers on the TV are not very effective in processing mid-bass sound signals, the bass part of the sound signal output by the traditional TV will be filtered out by the sound effect processor in the TV first, so that the left and right speakers The sound produced will not have too much low-frequency noise.

Therefore, based on this design, when the TV station sends a full-range program or plays a movie, the stereo sound played by the traditional TV does not have a bass part, so when the user watches a program with a heavy bass, such as a movie If you don't hear the sound of the engine in the middle, you can't enjoy the shock of the heavy bass. Therefore, often the user has to spend additional money to purchase a set of sound system in order to have the effect of subwoofer. Moreover, the purchased audio system also needs to be equipped with multiple audio source cables, and the length of these audio source wiring may need a certain length, which makes the entire audio system very complicated and may also hinder the user's traffic environment. But for the user who just wants to buy a TV to enjoy the subwoofer effect, this not only increases the budget, but also brings inconvenience to the user.

【Content of invention】

In view of this, the purpose of the present invention is to provide a wireless subwoofer audio system for electronic devices, so as to solve the problem that traditional TV sets do not have subwoofer, and transmit the subwoofer audio signal to the subwoofer through wireless transmission, so that Wireless woofer placement is more flexible.

According to the object of the present invention, a wireless subwoofer audio system for an electronic device is proposed. Electronic devices such as audio-visual playback systems. The audio-visual playing system includes an audio-visual playing host and a sound output device. One of the sound signals in the audio-visual playback system is sounded through the wireless subwoofer sound system. The wireless bass sound system includes a sound effect processor, a wireless transmission module and the above-mentioned sound output device. The sound effect processor and the wireless transmission module are arranged in the audio-visual playing host. The sound output device at least includes a subwoofer SP, a wireless receiving module and an amplifier 212 .

The sound effect processor receives sound signals and outputs bass sound signals accordingly. The wireless transmission module outputs the bass sound signal in a wireless transmission manner. The wireless receiving module is used for receiving bass audio signals in a wireless transmission manner. The amplifier is used for receiving the bass sound signal output by the wireless receiving module, and driving the bass speaker to emit sound accordingly.

【Description of drawings】

In order to make the above-mentioned purposes, features, and advantages of the present invention more comprehensible, a preferred embodiment is specifically cited below, and in conjunction with the accompanying drawings, the detailed description is as follows:

FIG. 1 is a schematic diagram of an electronic device according to a preferred embodiment of the present invention.

FIG. 2 is a block diagram of the wireless subwoofer system of the electronic device 100 in FIG. 1 .

【Detailed ways】

The present invention provides a wireless subwoofer audio system for an electronic device, which transmits subwoofer audio signals to the sound output device of the wireless subwoofer audio system in a wireless transmission manner, so that the placement of the sound output device is more flexible and reduces the need for setting sound source lines inconvenience caused.

Please refer to FIG. 1 , which is a schematic diagram of an electronic device according to a preferred embodiment of the present invention. The electronic device 100 is, for example, an audio-visual playing system. The video and audio playback system 100 includes a video and audio playback host 104 and a sound output device 108 . The audio-visual playing host 104 is, for example, a television or a computer system, and FIG. 1 is illustrated by taking a television as an example. Television sets include LCD TVs, plasma TVs, or cathode ray tube (Cathode Ray Tube, CRT) TVs, while computer systems include desktop computers, notebook computers, or barebone systems. In the embodiment of the present invention, the type of the audio-visual playing host 104 is not particularly limited. The audio output device 108 performs signal transmission with the audio-video player host 104 in a wireless transmission manner.

Please refer to FIG. 2 , which shows a block diagram of the wireless subwoofer system of the electronic device 100 in FIG. 1 . The wireless bass sound system 200 includes an audio processor 204 , a wireless transmission module 206 and the above-mentioned sound output device 108 . The audio processor 204 and the wireless transmission module 206 are configured in the audio-visual playing host 104 . The sound output device 108 at least includes a subwoofer SP, a wireless receiving module 210 and an amplifier 212 .

When the audio-visual playing host 104 is a TV set, the audio-visual signal VS is, for example, the audio-visual signal of a wireless or wired TV program, DVD, or VCD movie. After being processed by the audio-effect processor 204, the audio-effect processor 204 outputs left The channel sound signal L, the right channel sound signal R, and the bass sound signal SS with a frequency lower than 180 Hz. The sound effect processor 204, for example, utilizes a high-pass filter and a low-pass filter or an equalizer to frequency divide the high-frequency left and right channel sound signals L, R and the low-frequency bass sound signal SS. The audio signals L and R of the left and right channels output sound through two left and right speakers (speakers 114 and 116 shown in FIG. 1 ) of the television. The sound effect processor 204 outputs the bass sound signal SS to the wireless transmission module 206 .

The wireless transmission module 206 converts the bass sound signal SS into a wireless transmission mode, and outputs the bass sound signal SS' to the sound output device 108 . The wireless receiving module 210 of the sound output device 108 receives the bass sound signal SS' in a wireless transmission manner. The wireless receiving module 210 converts the bass sound signal SS" from a digital signal to an analog signal, and then transmits it to the amplifier 212. The amplifier 212 is used to receive the bass sound signal SS" output by the wireless receiving module 210, and convert the bass sound signal SS ” to amplify to drive the subwoofer SP to emit sound. The wireless transmitting module 206 and the wireless receiving module 210 are, for example, a Bluetooth transmitting module and a Bluetooth receiving module.

In this way, the TV set using the wireless subwoofer audio system of the present invention can have the function of playing subwoofer audio signals without purchasing an additional expensive audio system. Moreover, through wireless transmission, the placement of the sound output device 108 can be more flexible, so that users can arrange it according to their personal preferences without being limited by the length of the sound source cable. What's more, since the wireless subwoofer audio system of the electronic device of the present invention does not need to use the audio source cable, the user does not need to worry about the configuration of the audio source cable, making the home environment more beautiful and comfortable.

In summary, although the present invention has been disclosed as above with a preferred embodiment, it is not intended to limit the present invention. Anyone skilled in this art can make various modifications without departing from the spirit and scope of the present invention. Changes and modifications, so the scope of protection of the present invention should be defined by the scope of the appended patent application.
