【発明の詳細な説明】
本発明は例えば小形のラジオ或いはラジオ付カセットテ
ープレコーダ等に用いられるスピーカ装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker device used in, for example, a small radio or a cassette tape recorder with a radio.
近時ラジオ或いはラジオ付カセットテープレコーダ等は
ますます小形化の傾向にある。Recently, radios and cassette tape recorders with radios are becoming more and more compact.
従って、これにともないこれらに組込まれるスピーカも
小形化されているが、スピーカを小形化するとその分再
生周波数特性が悪くなるため良質な音を得られなくなる
。Accordingly, the speakers incorporated in these devices have also been made smaller, but as the speakers are made smaller, the reproduction frequency characteristics deteriorate accordingly, making it impossible to obtain high-quality sound.
そこで、従来ではスピーカの音質を極力良くすルタめに
例えばラジオ付カセットテープレコーダケースの大部分
をスピーカで占めるような大口径スピーカを用いたもの
がある。Therefore, in the past, in order to improve the sound quality of the speaker as much as possible, for example, a cassette tape recorder with a radio has a large-diameter speaker that occupies most of the case.
ところがこのように大きなスピーカを用いるとケースの
大きさに制限があるため他の部品とともにダイヤル表示
盤が著しく小形化されてしまいダイヤル表示が読みずら
くなる１頃向にある。However, when such a large speaker is used, the size of the case is limited, so the dial display panel along with other parts has to be significantly downsized, making it difficult to read the dial display.

できるスピーカ装置を提供することを目的とする。The present invention has been made in view of the above-mentioned circumstances, and a dial display panel is arranged using a space approximately in the center of the entire surface of the speaker body, and this display panel and one drive section thereof are connected by a drive shaft passing through the speaker body. To provide a speaker device in which the dial display panel can be enlarged regardless of the housing case of the speakers by being connected, the display can be made easier to read, and the entire device including the dial display panel and one driving section thereof can be compactly assembled. The purpose is to
以下、本発明の一実施例を第１図および第２図に従い説
明する。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.
ところで、図は本発明のスピーカ装置をラジオ付カセッ
トテープレコーダに用いた場合を示したもので、大口径
のスピーカ本体１１をラジオ付カセットテープレコーダ
ケース１２の正面に取付ける。By the way, the figure shows a case where the speaker device of the present invention is used in a cassette tape recorder with a radio, and a large-diameter speaker body 11 is attached to the front of a case 12 of the cassette tape recorder with a radio.
そして、このスピーカ本体１１の正面中央部つまりスピ
ーカの音質に影響しない正面中央位置にダイヤル表示盤
１３を配置する。The dial display panel 13 is disposed at the center of the front of the speaker body 11, that is, at the center of the front that does not affect the sound quality of the speaker.
この場合表示盤１３はスピーカ本体１１の前面を覆うス
ピーカパネル１４に取付けられる。In this case, the display panel 13 is attached to a speaker panel 14 that covers the front surface of the speaker body 11.
また、このときスピーカパネル１４はダイヤル表示盤１
３の部分を含め透明又は半透明の樹脂により一体成形さ
れている。Also, at this time, the speaker panel 14 is connected to the dial display panel 1.
It is integrally molded from transparent or translucent resin, including the part 3.
一方、前記スピーカ本体１１の中心軸線上にマグネット
１５、ヨーク１６を貫通して軸１７を回転自在に設ける
。On the other hand, a shaft 17 is rotatably provided on the central axis of the speaker body 11, passing through the magnet 15 and the yoke 16.
この軸１７は一端に前記ダイヤル表示盤１３の指針１８

すプーリ１９を夫夫取付けていて、図示しない選局ダイ

にしている。This shaft 17 has a pointer 18 of the dial display panel 13 at one end.
A pulley 19, which forms part of the drive section of the dial display panel 13, is attached to the other end of the dial display panel 13. I am trying to have the user specify the dial position.
ダイヤル表示盤１３の裏面にはこの表示盤１３の照明用
ランプ２０を設ける。A lamp 20 for illuminating the display panel 13 is provided on the back surface of the dial display panel 13.
このランプ２０はリード線２１を前記軸１７に沿ってス
ピーカ本体１１の後方に導出し、図示しない制御回路に
接続している。This lamp 20 has a lead wire 21 led out along the axis 17 to the rear of the speaker body 11 and connected to a control circuit (not shown).
しかし、このような構成によると大ロ径スヒー力本体正
面の音質に影響しない略中央部のスペースを利用してダ
イヤル表示盤のみを配置するようにしたのでダイヤル表
示盤をスピーカ収容ケースに関係なく大きくすることが
でき、その分表示を読みやすくすることができる。However, with this configuration, only the dial display board can be placed using the space in the center, which does not affect the sound quality in front of the large-diameter speaker unit, so the dial display board can be placed regardless of the speaker housing case. It can be made larger and the display can be made easier to read.
まだ、ダイヤル表示盤の指針とこれの駆動部をスピーカ
本体を挾んで配置し、これら間をスピーカ本体を貫通す
るとともに回転自在にした駆動軸で連結するようにした
ので、ダイヤル表示盤およびこれの駆動部を含めて全体
をコンパクトにまとめることができる。Still, the pointer of the dial display board and its drive part were placed between the speaker body, and they were connected by a drive shaft that penetrated the speaker body and was rotatable, so the dial display board and its drive part were arranged to sandwich the speaker body. The entire structure, including the drive unit, can be made compact.
寸だダイヤル表示盤の照明用ランプのリード線を前記１
駆動軸に沿ってスピーカ本体の後方に導出したのでリー
ド線の長さを極力短くでき経済的に有利である。Connect the lead wire of the illumination lamp of the dial display panel to 1 above.
Since the lead wire is led out to the rear of the speaker body along the drive shaft, the length of the lead wire can be made as short as possible, which is economically advantageous.
従って、このよ５なスピーカ装置を上述したラジオ付カ

形化に寄与スることもできる。Therefore, when this type of speaker device is used in the above-mentioned cassette tape recorder with a radio, there is no need to consider the installation space for the dial display panel on the cassette tape recorder side, and it is possible to provide more leeway in the arrangement of the parts for transmitting signals. In addition, it can also contribute to further downsizing of cassette tape recorders.
尚、本発明は上記実施例にのみ限定されず要旨を変更し
ない範囲で適宜変形して実施できる。It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be implemented with appropriate modifications without changing the gist.

装置を提供できる。As described above, according to the present invention, the dial display panel is arranged using the space approximately in the center of the front of the speaker body,
By connecting this display panel and its drive section with a drive shaft that passes through the speaker body, the dial display panel can be enlarged regardless of the speaker housing case, making the display easier to read, as well as the dial display panel and its drive section. It is possible to provide a speaker device that can be made compact as a whole.
