CDF4848A-102

apparence
Identification du modèle : la surface du diaphragme est marquée des logos « hd » (haute résolution) et « 100 % », indiquant qu’il est optimisé pour l’audio sur toute la bande passante.
structure physique :
Cadre : en métal argenté, avec des trous de fixation standard aux quatre coins (diamètre des trous d'environ 2 mm), assurant une stabilité mécanique.
Système de diaphragme : diaphragme en métal gris foncé avec suspension en caoutchouc noir pour assurer une course linéaire
Méthode de connexion : deux broches de soudure blanc argenté sont visibles sur la face avant (la distance est d’environ 5 mm), ce qui est pratique pour le soudage direct du circuit imprimé.
Caractéristiques du procédé : le rebord en caoutchouc et le cadre métallique sont laminés par ultrasons, assurant une bonne étanchéité.
caractéristiques
Audio haute résolution : plage de réponse en fréquence optimisée (estimée entre 200 Hz et 20 kHz), distorsion harmonique<1%<>
anti-magnetic design: the metal frame shields external electromagnetic interference
fast heat dissipation: metal structure assists voice coil heat dissipation
double soldering point design: the pins are pre-tinned and support reflow soldering process
advantages
strong installation compatibility: square design avoids rotational offset, hole position is compatible with m2 screws
lifespan up to 5,000 hours: the aging resistance of the rubber overhang is better than that of the foam edge
sensitivity ≥85db (1w/1m)
instructions
installation: fix to the panel through the four corner holes, the recommended torque is 0.4-0.6n·m
welding: preheat the pins to 260±10℃ and then weld, the duration is<3 seconds="">
driver: recommended power 1-10w (impedance 4Ω/8Ω needs to confirm the specification)
application scenarios
professional audio equipment: mixer monitoring unit/amplifier sound module
industrial hmi: human-machine interface alarm device/cnc equipment status indication
medical equipment: medical monitor beep/diagnostic equipment sound unit
car system: car navigation sound/radar alarm sounder
smart home: high-end doorbell/security sensor sound module
faq
q1: what is your moq?
a: our standard moq is 100 units for regular models. we can offer a lower moq for pilot orders, but the unit cost will be higher.
q2: can we customize the color or material of the speaker?
a: yes. color and material customization is available for oem/odm orders. please contact us with your specific requirements for a quotation.
q3: do you provide odm/oem services?
a: yes, we specialize in odm and oem services. we can design and produce speakers according to your technical specifications or design drawings.
q4: how long does it take to develop a new product?
a: the development time depends on the complexity. it typically takes 4-8 weeks for a new design, including prototyping and testing.
q5: what are your payment terms?
a: we commonly accept t/t (bank transfer). for new customers, 50% deposit is required to start production, and the balance 50% before shipment.
q6: can i mix different products in one container?
a: yes, mixed orders are welcome. this is a cost-effective way to import. we will provide a detailed packing list for each product.
