本発明はテレビジョン受像機に用いることのできる音響
装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an audio device that can be used in a television receiver.
従来例の構成とその問題点
近年、テレビシロン受像機はその形状をコンパクト化す

る。Conventional configurations and their problems In recent years, there has been a remarkable tendency to make the shape of television receivers more compact.Within this trend, one of the factors that hinders compactness is the shape of the speaker. Rectangular speakers with good factors and speaker mounting positions are well thought out. The mounting positions of a conventional television receiver and speakers will be explained below.

2 is the cabinet, and 2 is the mounting tool 4 on the front of the cathode ray tube 3.
, 5, 6. 7 are fixed transparent front plates made of glass or transparent resin, 8 are side plates of the cabinet, 9
is a speaker attached to the side panel of the cabinet.
このようにスピーカ９をキャビネット１の側面に取付け

られる。By attaching the speaker 9 to the side of the cabinet 1 in this way, the width of the television receiver can be reduced. However, since the speaker has a directional sound pressure characteristic, the speaker may be located at a position offset from the front axis of the speaker. In other words, in front of the television receiver, the high-frequency sound pressure decreases significantly.
Problems include deterioration in sound quality, and since the speakers are attached to the side of the cabinet, it becomes difficult to reproduce sound if there is an obstacle in the position corresponding to the speaker, and there are restrictions on the installation location. As a means to solve this problem, an acoustic device can be considered in which a drive unit is attached to a front plate provided in front of a cathode ray tube and the front plate is used as a diaphragm.
以下にこの方式の音響装置について説明する。This type of audio device will be explained below.

である。FIG. 2 is a perspective view of a television receiver of this type. Reference numeral 10 designates a driving unit), and the other parts are the same as those in FIG. 1, so a description thereof will be omitted. The drive unit 10 vibrates in response to applied electrical signals and acts as a vibrator, and since this vibrator is fixed to the front plate 2, it causes the front plate 2 to vibrate. The front plate 2 covers the entire front surface of the cathode ray tube 3, and its area is much larger than that of the diaphragm of a conventional speaker. Therefore, vibrations from the drive unit 1Q attached to one end of the front plate can be efficiently converted into acoustic output.
この方式では、テレビジョン受像機にスピーカを取付け

けることもない。This method does not require space for installing speakers on the television receiver, so it can be easily made compact. There is no restriction from one place.
しかし、前面板に駆動用ユニットを固着する際、面接触
をよくする為、接着剤などを用いていたが、凝固に時間

離することがあるなどの問題点があった。However, when fixing the drive unit to the front plate, adhesives were used to improve surface contact, but it took time to solidify, and the adhesive part peeled off due to the vibration of the front plate after long-term use. There were some problems, such as:
