しかしながら、従来の構造のスピーカでは、パチンコ業界でいうゴト師によるゴト行為には無力であった。すなわち、透音孔に針金等を突っ込んで、コーンを針金等で突っついてリード線を切断し、ガラス扉を開放しても、警告音がスピーカから出ないようにすることで、不正行為を行なったいた。これにより、パチンコ業界に甚大な被害が生じている。   However, conventional loudspeakers are powerless to goto acts by goto teachers in the pachinko industry. That is, cheating with a wire or the like into the sound transmission hole, cutting the lead wire with a wire or the like, cutting the lead wire, and opening the glass door prevents illegal sounds from coming out of the speaker. I hit it. This has caused tremendous damage to the pachinko industry.

そこで、本発明者は、鋭意検討の上、特許請求の範囲に記載の発明をなしたものである。本発明は、メインコーンと、ボイスコイルとボビンを有する振動部と、マグネットとヨークを有する静止部と、を備えた動電型スピーカと、前記振動板の正面側に配置された電飾部と、を備え、金属製のサブコーンを、前記メインコーンの正面に、配置し、前記サブコーンの裏側にリード線を配線したことを特徴とする遊技機用音響装置である。スピーカの、メインコーンと、振動部と、静止部は、遊技機用の一般的な構造が好ましい。   Therefore, the present inventor has made the invention described in the scope of claims after intensive studies.

For example, 0.05-1 mm and 0.1-0.5 mm are preferable, and 0.1-0.3 mm is particularly preferable. The diameter of the sub cone may be set at an appropriate ratio of the diameter of the main cone, and is not limited to a specific ratio. For example, 10 to 90% and 20 to 60% of the diameter of the main cone are preferable, and 30 to 50% is particularly preferable.

ボビンの前面の中央部にサブコーンの中心部を結合させる態様としては、接着、溶着等が好ましい。接着の態様は、接着剤、両面テープ等が好ましい。   As a mode in which the central portion of the sub cone is coupled to the central portion of the front surface of the bobbin, adhesion, welding, or the like is preferable.

この遊技機用音響装置1は、遊技機の音制御基板等により制御されるように構成されている。この実施形態においては、図柄が特定配列となって、一般入賞時やボーナス入賞時などの賞球獲得状態又はメダル獲得状態になった場合などにおいて、主制御基板からの指令信号によって音制御基板(図示略)を作動させて効果音を出力するようになっている。   The gaming machine acoustic device 1 is configured to be controlled by a sound control board or the like of the gaming machine. In this embodiment, the sound control board (in response to a command signal from the main control board in a case where the symbols are in a specific arrangement and a winning ball acquisition state or a medal acquisition state such as a general winning or a bonus winning is obtained. The sound effect is output by operating (not shown).

上記のような構成を備えた本実施形態の動作を説明する。まず、弾球遊技機からリード線140に電流が供給されると、ボイスコイル3に電流が流れ、これにより、マグネットで発生する磁束が鉄で出来たヨーク7に導かれボイスコイル3の所に強い磁場を作る。ボイスコイル3に流れる電流はこの磁場でローレンツ力を受け、振動部5が振動し、この動きがメインコーン2とサブコーン11に伝わり周りの空気を振動させ音を放出する。   The operation of this embodiment having the above configuration will be described. First, when a current is supplied from the ball game machine to the lead wire 140, a current flows through the voice coil 3, whereby the magnetic flux generated by the magnet is guided to the yoke 7 made of iron and is placed at the voice coil 3. Create a strong magnetic field. The current flowing through the voice coil 3 receives the Lorentz force by this magnetic field, and the vibration part 5 vibrates. This movement is transmitted to the main cone 2 and the sub cone 11 to vibrate surrounding air and emit sound.

遊技機の遊技中に、例えば、一般入賞時やボーナス入賞時などの賞球又はメダル獲得状態になった場合、音制御基板(図示略)から出力された音声信号は遊技機用音響装置1に入力され、この音響装置1から効果音等の音声が出力される。それとともに、電飾制御基板(図示略)からの電飾信号がLED基板101に出力されて、これに応答してLED100が発光する。   For example, when a winning ball or medal is acquired during a general winning or a bonus winning during the gaming machine, the audio signal output from the sound control board (not shown) is sent to the acoustic device 1 for the gaming machine. A sound such as a sound effect is output from the sound device 1. At the same time, an illumination signal from an illumination control board (not shown) is output to the LED board 101, and the LED 100 emits light in response thereto.

本実施形態によれば、ゴト師が針金でコーンを突付いても、金属製のサブコーン11で跳ね返されるので、リード線140は切断されずに済み、ゴト師がガラス扉を不正に開いても、警告音が正常に動電型スピーカ9から発生するので、不正対策の被害を防止することができる。   According to the present embodiment, even if Goto pierces the cone with the wire, it is rebounded by the metal sub-cone 11, so that the lead wire 140 is not cut and even if Goto opens the glass door illegally. Since the warning sound is normally generated from the electrodynamic loudspeaker 9, it is possible to prevent damage caused by fraud countermeasures.

本実施例は、メインコーン2の厚みが0.35mm、直径55mm、サブコーン11がアルミニウム製でその厚さが0.2mm、直径25mm、振動部5の軸方向長さ6mm、直径14mm、静止部8の直径19mm、軸方向長さ9mm、スピーカ9は抵抗8Ω、出力10Wである。   In this embodiment, the main cone 2 has a thickness of 0.35 mm, a diameter of 55 mm, the sub cone 11 is made of aluminum, the thickness is 0.2 mm, the diameter is 25 mm, the axial length of the vibration part 5 is 6 mm, the diameter is 14 mm, and the stationary part. 8 has a diameter of 19 mm, an axial length of 9 mm, the speaker 9 has a resistance of 8Ω and an output of 10 W.

なお、本発明は、上述の実施の形態に限定されるものではなく、本発明の技術的思想を逸脱しない範囲において、改変等を加えることが出来るものであり、それらの改変、均等物等も本発明の技術的範囲に含まれることとなる。例えば、音響装置1は円筒形に限らず、楕円、角形等でもよい。また、サブコーン11の形状、構造、配置等も発明の趣旨を逸脱しない範囲で適宜設定できる。LED部10の形状や構造も一例を示したもので、適宜、変形できる。振動部5も適宜変更でき、例えば、図7に示す通り、ボビン4の径を前述実施形態よりも細径にしたものでよい。LED部10は電飾のため設けたが、これをなくした構造でもよいことは無論である。   Note that the present invention is not limited to the above-described embodiment, and modifications and the like can be made without departing from the technical idea of the present invention. It will be included in the technical scope of the present invention. For example, the acoustic device 1 is not limited to a cylindrical shape, and may be an ellipse, a square, or the like. Further, the shape, structure, arrangement, and the like of the sub cone 11 can be set as appropriate without departing from the spirit of the invention. The shape and structure of the LED unit 10 are also examples, and can be appropriately modified. The vibration part 5 can also be changed as appropriate. For example, as shown in FIG. 7, the diameter of the bobbin 4 may be made smaller than that in the above embodiment. Although the LED unit 10 is provided for electric decoration, it is needless to say that the structure without the LED unit 10 may be used.
