Abstract

This invention is about a shoulder-mounting vibrating woofer speaker which is worn on users' shoulders, and which is a U-shaped speaker structure mounting a small-sized vibrating speaker unit and a small-sized woofer speaker unit. Shoulder-mounting woofer speaker is apart about 15cm from users' ears. This short distance between speakers and ears allows a small-sized and low-output woofer create rich sounds and save power usage at the same time. A woofer miniaturized to a suitable size enable to make a wireless vibrating woofer with low power usage operated by batteries, and this vibrating speaker unit supplements the defect of limited low frequency sounds of this small-sized woofer unit acting like a high output woofer speaker by creating live ambience and transmitting vibration to user's body.

Description

U SHAPE VIBRO WOOFER WHICH IS WEARING ON SHOULDER
[TECHNICAL FIELD] This invention is about a shoulder-mounting vibrating woofer speaker which is worn on users' shoulders, and which is a U-shaped speaker structure mounting a small-sized vibrating speaker unit and a small-sized woofer speaker unit.
[BACKGROUND ART] In case of current woofer speakers, they necessarily should have a wide speaker unit to enrich low-frequency sounds. Consequently not only the volume and weight of the speaker units get big and heavy with inefficient power usage, but also they cause inconvenience of shifting. Head-set model of vibrating woofer speakers have been invented recently to cover these disadvantages partly.
But the speakers squeeze and vibrate users ' heads directly causing them physical fatigue to body and brain when they use the speakers for a long time.
These speakers have also limitation to carry sounds from 4 or 5.1 channel. In case of current woofer speakers, they only serve one-sided, identical sounds to all people in the place where the speakers are installed, not allowing users the choice of selected sounds. Covering all those disadvantages, this invention includes a woofer speaker building deep sounds in spite of its small size, a woofer miniaturized to a suitable size for body mounting and a wireless vibrating woofer with low power usage operated by batteries.
This shoulder-mounting woofer also enhances 3D surround effects and alleviates the load thoroughly caused by headsets.
[DISCLOSURE OF INVENTION] To achieve above goal, this invention mainly consists of parts as follows. - Speaker structure upper body which the woofer speaker unit is fixed on. (100) - Speaker structure lower body which the vibration speaker unit is fixed on. (200) Amplifier which amplify input sound signal and filter mid-high frequency band. (300) - Woofer speaker unit which convert inputted low frequency band signal to sound. (400) - Vibration speaker unit which convert inputted low frequency band signal to live vibration. (500) Woofer speaker unit is fixed on speaker structure upper body(I OO) to transmit sound to ears directly, while vibration speaker unit is fixed on speaker structure lower body(200) to transmit maximum vibration.
Inside of U-shape structure body is cylindrical form to make sound rich and soft by resonating sound, it is internally divided by wall(900) to prevent interference of stereo sound. The description of an execution example according to this invention by attached drawings is as follows.
Fig.1 : Drawing of U shape vibro woofer which is wearing on shoulder according to this invention. Fig.2: Drawing of structure upper (housing)body of U shape vibro woofer which is wearing on shoulder according to this invention.
Fig.3: Drawing of structure lower (housing)body of U shape vibro woofer which is wearing on shoulder according to this invention.
Fig.4: Constructive drawing of U shape vibro woofer which is wearing on shoulder according to this invention.
Fig.5: Drawing for wearing of U shape vibro woofer which is wearing on shoulder according to this invention Operating process of vibro woofer speaker is as follows.
Amplifier(300) receives audio signal from audio signal output, and converts signal to sound via woofer speaker unit(400) after filtering of mid-high frequency band voice signal, simultaneously amplifier converts signal to up/down motion vibration via vibration speaker unit.
For this invention, besides woofer speaker unit, additional wide band sound speaker units(600) can be installed to raise surround sound effect. In this case, an amplifier doubly equipped with wide band amplifier is necessary.
For this invention, not a vibration-only speaker but a dual mode speaker which generates vibration and sound simultaneously can be adopted. [BRIEF DESCRIPTION OF THE DRAWINGS]

Amplifier(300) receives audio signal from audio signal output, and converts signal to sound via woofer speaker unit(400) after filtering of mid-high frequency band voice signal, simultaneously amplifier converts signal to up/down motion vibration via vibration speaker unit.
For this invention, besides woofer speaker unit, additional wide band sound speaker units(δOO) can be installed to raise surround sound effect. In this case, an amplifier doubly equipped with wide band amplifier is necessary.
For this invention, not a vibration -only speaker but a dual mode speaker which generates vibration and sound simultaneously can be adopted.
[INDUSTRIAL APPLICABILITY] Shoulder-mounting woofer speaker is apart about 15cm from users' ears.
This short distance between speakers and ears allows a small-sized and low- output woofer creates rich sounds and save power usage at the same time. A woofer miniaturized to a suitable size enable to make a wireless vibrating woofer with low power usage operated by batteries, and this vibrating speaker unit supplements the defect of limited low frequency sounds of this small-sized woofer unit acting like a high output woofer speaker by creating live ambience and transmitting vibration to user's body. This invention improves the 3D surround effects by stimulating neck and shoulder into which acute nerves are centralized and by generating sounds at just below users' ears delivering all detail sounds to users.
Furthermore this woofer has lower volume than other current woofers so that users can enjoy the sound without bothering other people. This woofer can play a similar role as a rear surround speaker when it is connected to other front speakers because sound speaker unit(600) is located behind user's ears. But, in this case, besides woofer speaker unit, additional wide band sound speaker units should be installed. This invention helps users to enjoy TV programs, DVD and music with live ambience by powerful vibration onto users body.
