Abstract
The utility model provides a low sound supplementary device for an audio unit of electronic equipment; the audio frequency of the existing electronic equipment is divided, the existing electronic equipment is used for outputting high-mid sound to be played, a low sound signal is output by wireless transmission, the low sound is played by a wireless low-sound box, and synchronous regulation of the volume of high-mid sound and the low sound is realized at the meantime. By utilizing the audio unit of the existing electronic equipment and combing the wireless low-sound system, the audio effect with good cost performance is realized; multiple-client exclusive access or sharing access is simple, so as to be convenient for usage.
Description
Technical field
The utility model relates to a kind of electronic installation, and as panel TV, the acoustics of notebook computer etc. is in particular for its acoustics that provides a kind of bass to replenish.
Background technology
Have now and have audio frequency, the electronic equipment of video output is for ease of carrying, or be convenient to install, trend towards miniaturization and microminiaturization, as panel TV set, its display area, increasing, but thickness is more and more thinner, offers an explanation very high, but because panel TV is thin, its audio amplifier of being with also requires attenuation naturally, and for this reason, the designer has proposed all designs, design audio amplifier elongated, increase the audio amplifier area, expect that it has bass tonequality preferably, but because audio amplifier is too thin, do not have enough volumes, be difficult to accomplish bass preferably.Mancarried electronic aid, as mobile phone, MP3, MP4 player, electronic organ, broadcast receiver etc., for ease of carrying, its audio amplifier is very little naturally, and its bass effect is poor.And for the high pitch part, can meet the demands substantially.
For improving above-mentioned electronic equipment, existing improving one's methods be or be with audio amplifier in addition, or wired, or wireless, and wired audio amplifier has improved acoustical quality, but the tape line for decorating good room, has destroyed whole structure especially; Wireless sound box, the tonequality of improving, can furnish arbitrarily, but will have electronic equipment now, the sound equipment of panel TV set cancels, wasted existing resource, its two existing Bluetooth wireless transmission, its bandwidth is 128K, full range transmission bandwidth deficiency, many musical notes are lost, and full range wireless transmission effect is bad, cost is higher.
The utility model content
The purpose of this utility model is to utilize the sound equipment of existing electronic equipment, and combining wireless hang down system for electrical teaching, realizes the good acoustics of cost performance, the multi-user is held monopolize or share to insert to become very simple, convenient use.
The technical solution of the utility model is the audio frequency frequency division with existing electronic equipment, wherein exporting high middle pitch with existing electronic equipment plays, with wireless transmission output bass signal, play bass by the wireless bass audio amplifier, realize the volume adjusted in concert of high middle pitch and bass simultaneously.
A kind of acoustics of electronic equipment comprises frequency unit, a high middle pitch playing device, one bass frequency division processor is in order to export a wireless bass audio amplifier with the bass signal of frequency unit output with Wireless transmission mode, it comprises a radio receiver, an amplifying device, and bass horn.
Described radio transmitting device and described receiving system can be Bluetooth transmission, WiMAX, frequency modulation or other wireless transmission method.
Described electronic installation is panel TV set, mobile phone, notebook, MP3, MP4, electronic organ, broadcast receiver etc.
Panel TV set, notebook computer, external bass sound equipment such as mobile phone, can shared one or more wireless bass audio amplifier, especially as the bass part of musical instruments such as electronic organ, can many whiles shared, then it can not be worked simultaneously for panel TV set or mobile phone or notebook computer.
Another technical scheme of the present utility model is a kind of acoustics of electronic installation, comprises that one is arranged on the high middle pitch playing device of electronics, an audio wireless emitter, an apparatus for receiving audio, a bass amplifying device, a woofer; The course of work is: the body by electronic installation sends high middle pitch, and voice signal is sent by wireless device simultaneously, is received by a radio receiver, and the bass part frequency is broadcasted after amplifying.This scheme is to be replenished by the bass part of other wireless sound box to electronic installation equally.
The sound system of the existing electronic installation of the utility model utilization is play high middle pitch, the high alto branch of electronic installation behind frequency division can be done higher power like this, with bass part through being wirelessly transmitted to wireless acoustics, play through receiving to amplify, existing Bluetooth transmission bandwidth can satisfy the needs of the transmission signals flow of bass fully.The utility model sends high alto branch on primary electron equipment, send with the video equipment homology, and lower part is sent from the audio amplifier that separates, and bass does not have directivity, and therefore, it is synchronous that this scheme has good video tone.
Description of drawings
Fig. 1 is a circuit block diagram of the present utility model;
Embodiment is further described the utility model below in conjunction with accompanying drawing:
As shown in the figure, embodiment 1: be applied to panel TV, this device comprises USB Bluetooth audio frequency reflector (4), panel TV set (1), blue teeth wireless receives bass box (5), this device comprises that USB Bluetooth audio frequency reflector (4) comprises USB sound card (4.1), and frequency division module (4.2), USB Bluetooth audio frequency reflector (4) is plugged on the USB port of panel TV (1), and the audio signal of TV can be obtained by USB, also can be imported by CD IN, carry out frequency division by frequency division module 4.2, take out bass signal, after treatment by Bluetooth transmission, blue teeth wireless receives the bass box reception after power amplification promotes the bass effect that bass horn replenishes TV.
The Bluetooth audio frequency reflector of present embodiment is outer the access, go for the panel TV set that using, plug USB Bluetooth audio frequency reflector (4), the bass part of panel TV set (1) just can receive bass box (5) from blue teeth wireless and send, and replenishes the bass part of former television set.For manufacturing television set then can be a built-in bluetooth transmitters, directly is provided with on the circuit of television set, and frequency division transmits out with bass signal.
Embodiment 2: for being applied to notebook computer (2) and mp3, MP4 handheld devices such as (3):
A. notebook, MP3, MP4 have embedded with bluetooth, directly adorn driver, audio signal, and alt is by notebook, and the loudspeaker that MP3, MP4 carry send, and bass is amplified synthetic complete voice sound after by frequency division to bass box by the Bluetooth transmission signal.
B. notebook computer is not with embedded with bluetooth, USB Bluetooth audio frequency reflector (4) directly is inserted on the notebook USB interface, load onto driver after, USB sound card and notebook carry the sound card co-operation, bass is handled the back Bluetooth transmission by the USB sound card, and woofer receives and amplifies.
